In the related art, when the outdoor environment temperature is lower, the controller component of the air source heat pump unit is affected by the temperature, the temperature of the cavity of the controller component is lower, components such as a capacitor, a fan driving component and a compressor driving component in the controller component cannot normally operate, and further the operation of the components such as a compressor and a fan of the air source heat pump unit cannot be accurately controlled, so that the air source heat pump unit cannot be accurately controlled to heat in a low-temperature environment.

Based on the above situation, the embodiment of the present disclosure proposes a temperature control method, please refer to fig. 1A, and fig. 1A is a schematic diagram of a temperature control method according to the embodiment of the present disclosure.

Illustratively, as shown in FIG. 1A, the air source heat pump unit includes a water side heat exchanger, a compressor, a fin heat exchanger, a fan, a main electronic expansion valve, an economizer, an auxiliary electronic expansion valve, a controller assembly, and the like. The controller component is connected with the auxiliary electronic expansion valve, the main electronic expansion valve, the fan and the compressor and is used for controlling the operation of the auxiliary electronic expansion valve, the main electronic expansion valve, the fan and the compressor to realize accurate temperature regulation.

The heating assembly is used for heating the cavity of the controller assembly, the fan in the cavity is used for increasing airflow flow of the cavity of the controller assembly, and heat generated by the heating assembly is conveyed to all positions of the cavity. The cavity temperature sensor is used for acquiring the temperature of the cavity. The power supply assembly is used for providing power to the controller, the heating assembly, the fan in the cavity and the cavity temperature sensor. The controller is used for controlling the operation of the heating component, the fan in the cavity and the cavity temperature sensor.

In the embodiment of the application, the controller starts the heating component and the fan in the cavity, and the fan in the cavity transfers the heat generated when the heater component heats to the whole cavity of the controller component, so that the temperature of the cavity of the controller component can be increased, and based on the temperature, each component contained in the controller component can normally operate, and therefore, the air source heat pump unit can be accurately controlled to heat in a low-temperature environment.

Referring to fig. 1C, fig. 1C is a schematic architecture diagram of a controller assembly according to an embodiment of the disclosure.

Illustratively, as shown in FIG. 1C, the controller assembly further comprises: the first driving assembly and the first temperature sensor are respectively connected with the controller and the power supply assembly. The first driving component is used for driving the fan controlled by the controller component to run, the first temperature sensor is used for collecting the temperature of the first driving component, the controller is used for controlling the first driving component and the first temperature sensor, and the power supply component is used for providing power supply for the first driving component and the first temperature sensor.

The first drive assembly may be, for example, in particular a fan drive assembly, which controls the operation of a fan in the air source heat pump unit. In the embodiment of the application, the operation of the fan can be controlled by the temperature of the first driving component acquired by the first temperature sensor. For example, when the first temperature sensor collects that the temperature of the first driving component is low, it is determined that the outdoor environment temperature is low, and the fan of the air source heat pump unit can be controlled to run at a low speed through the first driving component. When the fan of the air source heat pump unit runs at a low speed, current passes through the first driving assembly to generate heat, so that the temperature of the first driving assembly is increased. In the process of low-speed operation of the fan of the air source heat pump unit, the first temperature sensor collects that the temperature of the first driving assembly rises to the normal operation range of the first driving assembly, and the fan of the air source heat pump unit is controlled to stop operating through the first driving assembly under the condition that a user starts an instruction of the air source heat pump unit.

In the embodiment of the application, the operation of the fan of the air source heat pump unit is controlled through the first temperature sensor and the first driving component in the controller component, so that the low current flowing through the first driving component when the fan operates, the temperature of the first driving component is increased in a low-temperature environment, and the first driving component is ensured to be started and operated normally.

The second drive assembly may in particular be a compressor drive assembly, which controls the operation of a compressor in the air source heat pump unit, for example. In the embodiment of the application, the second driving assembly can be controlled to operate through the temperature of the second driving assembly acquired by the second temperature sensor. For example, when the second temperature sensor collects that the temperature of the second driving assembly is low, it is determined that the outdoor environment temperature is low, and the compressor of the air source heat pump unit can be controlled to operate at a low speed through the second driving assembly. When the compressor of the air source heat pump unit runs at a low speed, current passes through the second driving assembly to generate heat, so that the temperature of the second driving assembly is increased. In the process of low-speed operation of the compressor of the air source heat pump unit, the second temperature sensor collects that the temperature of the second driving assembly rises to the normal operation range of the second driving assembly, and under the condition that a user starting an instruction of the air source heat pump unit is not received, the compressor of the air source heat pump unit is controlled to stop operation through the second driving assembly.

In the embodiment of the application, the operation of the compressor of the air source heat pump unit is controlled through the second temperature sensor and the second driving component in the controller component, so that the low current flowing through the second driving component when the compressor operates is used for improving the temperature of the second driving component, the temperature of the second driving component is improved in a low-temperature environment, and the second driving component is ensured to be started and operated normally.

The temperature control method provided in the present specification will be described in detail with reference to specific examples.

Fig. 2 is a schematic flow chart of a temperature control method according to an embodiment of the present disclosure. As shown in fig. 2, the method of the embodiment of the present specification may include the following steps S101 to S103.

S101, acquiring a first cavity temperature of a controller assembly acquired by a cavity temperature sensor;

In one embodiment, the first cavity temperature may be a temperature of an internal cavity of the controller assembly acquired by the cavity temperature sensor. When the outdoor ambient temperature is low, the temperature of the cavity of the controller assembly is low, and thus the first cavity temperature acquired by the cavity temperature sensor is low. In the embodiment of the application, the frequency of the first cavity temperature of the controller assembly can be controlled by the outdoor environment temperature of the region where the air source heat pump unit is located and the operation condition of the air source heat pump unit, for example, if the outdoor environment temperature is-30 ℃ and the air source heat pump unit is in a standby state, the first cavity temperature of the controller assembly is controlled by the cavity temperature sensor every 3 seconds, and the first cavity temperature of the controller assembly is controlled by the cavity temperature sensor every 5 seconds when the outdoor environment temperature is-20 ℃ and the air source heat pump unit is in a standby state.

S102, acquiring a first duration of time that the temperature of the first cavity is smaller than a first temperature threshold;

In one embodiment, the first temperature threshold may be a temperature that determines whether the first cavity temperature of the controller assembly is lower than a temperature at which each of the controller assemblies is operating properly. For example, the power supply assembly, the first drive assembly, and the second drive assembly in the controller assembly typically do not operate properly at-30℃ due to the relatively low temperature. In view of the need to maintain the temperature of the controller components, such as the power supply component, the first drive component, and the second drive component, above-30 c, there may be a design margin of 3c, i.e., the temperature of the controller components is controlled to be not lower than-27 c. In order to make the temperature of the controller component not lower than-27 ℃, the air temperature of the cavity not lower than-23 ℃, so that the temperature of the cavity of the controller component is required to be maintained above-23 ℃, and a power supply component, a first driving component and a second driving component in the controller component normally operate. Based on this, the first temperature threshold may be set to-23 ℃, and when the first cavity temperature of the controller assembly is obtained to be less than-23 ℃, a timer is started to count, and a first duration of time that the first cavity temperature is obtained to be less than-23 ℃ is obtained, and in an embodiment of the present application, the first duration may be 5S (seconds).

It will be appreciated that when the first cavity temperature is greater than or equal to the first temperature threshold, then it is determined that the first cavity temperature of the controller assembly satisfies normal operation of the various components of the controller assembly, and the step of obtaining the first length of time is not performed, i.e., no adjustment is required to the first cavity temperature of the controller assembly.

And S103, when the first time length reaches a first time length threshold value, starting the heating assembly and the fan in the cavity, controlling the heating assembly and the fan in the cavity to increase the temperature of the first cavity to a target temperature, wherein the target temperature is greater than or equal to a second temperature threshold value, and the second temperature threshold value is greater than the first temperature threshold value.

In an embodiment, the first time threshold may be a time threshold for determining whether to activate the heating assembly and the blower within the cavity when the first cavity temperature is less than the first temperature threshold. And when the time length that the temperature of the first cavity is smaller than the first temperature threshold reaches the first time length threshold, the temperature of the cavity representing the controller component is stably maintained to be lower than the first temperature threshold, and if the fact that the cavity of the controller component needs to be heated is determined, the heating component and the fan in the cavity are controlled to be started. For example, the heating assembly and the blower within the cavity may be controlled to be activated simultaneously to raise the temperature of the cavity of the controller assembly.

In an embodiment, when it is determined that the cavity of the controller assembly needs to be heated, the heating assembly may be started to heat the cavity first, and after the heating time of the heating assembly reaches a preset heating time, for example, 10S, the blower in the cavity is controlled to be started to deliver heat generated by the heating assembly to each position of the cavity of the controller assembly.

In another embodiment, the heating power of the heating assembly and the rotation speed of the fan in the cavity can be controlled, for example, if the rotation speed of the fan in the cavity can be controlled to be lower under the condition that the heating power of the heating assembly is lower, the rotation speed of the fan in the cavity can be controlled to be higher under the condition that the heating power of the heating assembly is higher, and the fan in the cavity can be controlled to operate at a higher rotation speed under the condition that the heat generated by the heating assembly is higher, so that the heat can be quickly conveyed to various positions inside the controller assembly.

In yet another embodiment, the heating assembly may be further controlled to operate at a higher heating power for a period of time after start-up, and during this period the blower within the cavity may be controlled to operate at a higher rotational speed. After heating reaches a certain time, the heating component is controlled to reduce heating power, and the fan in the cavity is controlled to reduce the rotating speed, so that the problem that the temperature of the cavity of the controller component rises faster to damage the component when heating is performed with larger heating power in the later heating period is avoided.

In one embodiment, the first chamber temperature is raised to a target temperature by a heating assembly and an indoor fan.

In the embodiment of the application, when the first cavity temperature of the controller assembly is lower than the first temperature threshold and the first time length of the first cavity temperature smaller than the first temperature threshold reaches the first time length threshold, the heating assembly and the blower in the cavity are controlled to be started, the blower in the cavity is used for conveying heat generated by the heating assembly to each position of the controller assembly, and the first cavity temperature of the controller assembly is improved, so that the components positioned at each position of the controller assembly can be normally started and operated, the controller assembly can also control the normal operation of the air source heat pump unit under the low-temperature environment, and the operation accuracy of the air source heat pump unit is improved.

Referring to fig. 3, a schematic flow chart of a temperature control method is provided in the embodiment of the present disclosure. As shown in fig. 3, the method of the embodiments of the present specification may include the following steps S201 to S204.

S201, acquiring a first cavity temperature of a controller assembly acquired by a cavity temperature sensor;

specifically, please refer to the description of step S101 in the above embodiment of the present disclosure, which is not repeated herein.

S202, when the temperature of the first cavity is smaller than a first temperature threshold value, acquiring first operation information of a fan in the cavity and second operation information of a cavity temperature sensor;

In one embodiment, when the first cavity temperature is less than a first temperature threshold, first operational information of the fan within the cavity and second operational information of the cavity temperature sensor are obtained. The first operation information is the operation information of the fan in the cavity, and the second operation information is the operation information of the cavity temperature sensor. The first operating information of the fan and the second operating information of the cavity temperature sensor in the cavity can be obtained when the first cavity temperature is smaller than the first temperature threshold value.

In other embodiments, the first operating information of the fan in the cavity and the second operating information of the cavity temperature sensor may also be obtained by a sensor such as a current detector.

S203, when the first operation information is the fan fault-free information in the cavity and the second operation information is the cavity temperature sensor fault-free information, acquiring a first duration that the first cavity temperature is smaller than a first temperature threshold;

In an embodiment, the first operation information may be no-fault information of the fan in the cavity or fault information of the fan in the cavity, and the second operation information may be no-fault information of the cavity temperature sensor or fault information of the cavity temperature sensor. If the first operation information is the failure-free information of the fan in the cavity and the second operation information is the failure-free information of the cavity temperature sensor, the first cavity temperature acquired by the representative cavity temperature sensor can accurately represent the cavity temperature of the controller assembly, and the fan in the cavity can be controlled to normally operate, so that heat accumulation is avoided, the next step, namely starting a timer, is performed, and the first duration that the first cavity temperature is smaller than the first temperature threshold is acquired.

S204, when the first time length reaches a first time length threshold value, starting the heating assembly and the fan in the cavity, controlling the heating assembly and the fan in the cavity to increase the temperature of the first cavity to a target temperature, wherein the target temperature is greater than or equal to a second temperature threshold value, and the second temperature threshold value is greater than the first temperature threshold value.

Specifically, please refer to the description of step S103 in the above embodiments of the present disclosure, which is not repeated herein.

In the embodiment of the application, when the cavity temperature sensor and the fan in the cavity are determined to be fault-free, the first duration that the first cavity temperature is smaller than the first temperature threshold is acquired, so that the heating component and the fan in the cavity are started under the condition that the first cavity temperature is determined to accurately represent the cavity temperature of the controller component and the fan in the cavity is fault-free, and the accuracy of improving the first cavity temperature of the controller component is improved.

Further, in the embodiment of the present application, after the heating assembly and the blower in the cavity are started, there is a case that a control signal for starting the compressor is received, for example, it may be required to start the compressor for a user, and the indoor environment temperature is increased. And when the control signal is received, acquiring the second cavity temperature of the controller assembly detected by the cavity temperature sensor, and controlling the operation of the compressor of the air source heat pump unit based on the second cavity temperature when the second cavity temperature is smaller than or equal to a third temperature threshold, wherein the third temperature threshold is larger than the second temperature threshold.

Specifically, the second cavity temperature may be a temperature detected by the cavity temperature sensor upon receiving a control signal to start the compressor, which may be-20 ℃, for example. The third temperature threshold may be a temperature threshold that determines whether the compressor of the air source heat pump unit needs to be controlled when a control signal to start the compressor is received. When the second cavity temperature is less than or equal to the third temperature threshold, it is determined that the rotational speed of the compressor of the air source heat pump unit needs to be controlled, for example, the rotational speed of the compressor is controlled to run at a low speed of 15rps (revolutions per second).

Further, in an embodiment of the present application, an operation duration of the compressor according to the first rotational speed threshold may be determined based on the second cavity temperature, and the compressor may be controlled to operate according to the first rotational speed threshold during the operation duration. Specifically, when the second cavity temperature is less than or equal to the third temperature threshold (25 ℃), an operating duration of the compressor according to the first rotational speed threshold is determined based on the second cavity temperature. Illustratively, at a second cavity temperature of-20 ℃, determining that the compressor is operating at a first rotational speed threshold (e.g., 30 rps) for a period of 6 minutes; determining that the compressor is operated at a first rotational speed threshold (e.g., 30 rps) for 4 minutes at a second cavity temperature of-15 ℃; determining that the compressor is operated at a first rotational speed threshold (e.g., 30 rps) for 3 minutes at a second cavity temperature of-5 ℃; determining that the compressor is running at a first rotational speed threshold (e.g., 30 rps) for 2 minutes at a second cavity temperature of 10 ℃; at a second cavity temperature of 25 ℃, it is determined that the compressor is operated at a first rotational speed threshold (e.g., 30 rps) for a period of 1min.

In the embodiment of the application, after the heating component and the fan in the cavity are started, if a control instruction for starting the compressor is received, and the second cavity temperature of the controller component detected by the cavity temperature sensor is smaller than or equal to a third temperature threshold value, the operation of the compressor is controlled based on the second cavity temperature. By controlling the operation of the compressor, damage to the compressor caused by direct operation of the compressor at a relatively high rotational speed is avoided. And further, the operation time length of the compressor according to the first rotation speed threshold value is determined through the temperature of the second cavity, and the compressor is controlled to operate according to the first rotation speed threshold value within the operation time length, so that the operation of the compressor is accurately controlled.

Further, in an embodiment, after the heating assembly and the blower in the cavity are started, the first cavity temperature of the controller assembly is collected in real time by the control cavity temperature sensor, the first cavity temperature is updated, when the first cavity temperature reaches a second temperature threshold, a timer is started for timing, a second time length when the first cavity temperature reaches the second temperature threshold is obtained, and when the second time length reaches a second time length threshold, the heating assembly and the blower in the cavity are controlled to be closed. The second temperature threshold may be a temperature value that determines to turn off the heating assembly after the heating assembly is started, and the second duration threshold may be a duration that determines to turn off the heating assembly and the blower within the cavity after the heating assembly is started. Illustratively, the second temperature threshold may be-15 ℃, and the second duration threshold may be 5S.

When the first cavity temperature reaches the second temperature threshold value, the heating assembly and the fan in the cavity are controlled to be closed, so that when the first cavity temperature of the controller assembly reaches the parts of the controller assembly in normal operation, the heating assembly and the fan in the cavity are closed, and the controller assembly is prevented from being damaged due to the fact that the first cavity temperature of the controller assembly is too high.

Referring to fig. 4, a schematic flow chart of a temperature control method is provided in the embodiment of the present disclosure. As shown in fig. 4, the method of the embodiments of the present specification may include the following steps S301 to S305.

S301, acquiring a first temperature of a first driving assembly acquired by a first temperature sensor;

In one embodiment, the first temperature sensor is coupled to the first drive assembly, whereby the first temperature sensor senses a first temperature of the first drive assembly.

S302, acquiring a third duration that the first temperature is smaller than a fourth temperature threshold;

In one embodiment, the fourth temperature threshold may be a temperature that determines whether the temperature of the cavity of the controller assembly meets the temperature at which the first drive assembly operates, which may be-27 ℃ for example. And when the first temperature is determined to be smaller than the fourth temperature threshold value, starting a timer, and acquiring a third duration when the first temperature is smaller than the fourth temperature threshold value.

S303, when the third time length reaches a third time length threshold value, controlling the fan of the air source heat pump unit to start by using a second rotating speed threshold value, and updating the first temperature;

In an embodiment, when the third time period is greater than or equal to the third time period threshold, and it is determined that the first temperature of the first driving assembly is maintained below the fourth temperature threshold, controlling to start the fan of the source heat pump unit by using the second rotation speed threshold. The second rotational speed threshold may be a rotational speed set to raise the temperature of the first drive assembly, which is typically low, and may be 10rps, for example.

It will be appreciated that the fan of the air source heat pump unit is controlled by the first drive assembly, and during the process of starting the fan of the control source heat pump unit to rotate at the second rotational speed threshold, a low current is generated in the first drive assembly, thereby increasing the first temperature of the first drive assembly.

Thus, under the condition that the fan is started, the first temperature sensor acquires the first temperature of the first driving assembly in real time.

S304, acquiring a fourth duration that the first temperature is greater than or equal to a fifth temperature threshold;

In one embodiment, when the first temperature is greater than or equal to the fifth temperature threshold, a fourth time period is obtained in which the first temperature is greater than or equal to the fifth temperature threshold. Illustratively, the fifth temperature threshold may be-15 ℃.

And S305, controlling to turn off the fan when the fourth time reaches a fourth time threshold.

In one embodiment, the fan is controlled to be turned off when the fourth time reaches a fourth time threshold. Illustratively, the fourth time length threshold may be 4min. It can be understood that when the fourth time period that the first temperature is greater than or equal to the fifth temperature reaches the fourth time period threshold, the first temperature of the first driving component is determined to be stably maintained at the fifth temperature threshold, and the first driving component can be normally started and operated, so that the fan can be controlled to be turned off.

In the embodiment of the application, when the first temperature of the first driving component is lower, the fan is started to operate according to the second rotating speed threshold value, the first temperature of the first driving component is increased, and when the first temperature of the first driving component reaches the normal operation of the first driving component, the fan is closed, and the first temperature of the first driving component is increased by opening and closing the fan, so that the normal starting and operation of the first driving component in a low-temperature environment are controlled.

Referring to fig. 5, a schematic flow chart of a temperature control method is provided in the embodiment of the present disclosure. As shown in fig. 5, the method of the embodiments of the present specification may include the following steps S401 to S405.

S401, acquiring a second temperature of a second driving assembly acquired by a second temperature sensor;

In one embodiment, the second temperature sensor is coupled to the second drive assembly, whereby the second temperature sensor senses a second temperature of the second drive assembly.

S402, obtaining a fifth duration that the second temperature is smaller than a sixth temperature threshold;

In one embodiment, the sixth temperature threshold may be a temperature that determines whether the temperature of the cavity of the controller assembly meets the temperature at which the second drive assembly operates, which may be-27 ℃ for example. And starting a timer when the second temperature is determined to be smaller than the sixth temperature threshold value, and acquiring a fifth duration when the second temperature is determined to be smaller than the sixth temperature threshold value.

S403, when the fifth time length reaches a fifth time length threshold value, controlling the start of a compressor of the air source heat pump unit by a third rotating speed threshold value, and updating the second temperature;

in an embodiment, when the fifth time period is greater than or equal to the fifth time period threshold, and it is determined that the second temperature of the second driving assembly is maintained below the sixth temperature threshold, the compressor of the source heat pump unit is controlled to be started and controlled by the third rotation speed threshold. The third rotational speed threshold may be a rotational speed set to raise the temperature of the second drive assembly, which is typically low, and may be 10rps, for example.

It will be appreciated that the compressor of the air source heat pump unit is controlled by the second drive assembly, and that during the start-up control of the compressor of the air source heat pump unit to rotate at the third rotational speed threshold, a low current is generated in the second drive assembly, whereby the second temperature of the second drive assembly may be increased.

In some cases, the actions or steps recited in the claims can be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results.

The controller assembly in this specification may include one or more of the following: processor 110, memory 120, input device 130, output device 140, and bus 150. The processor 110, the memory 120, the input device 130, and the output device 140 may be connected by a bus 150.

The processor 110 connects various parts within the overall controller assembly using various interfaces and lines, performs various functions of the terminal 100 and processes data by executing or executing instructions, programs, code sets, or instruction sets stored in the memory 120, and invoking data stored in the memory 120. Alternatively, the processor 110 may be implemented in at least one hardware form of digital signal Processing (DIGITAL SIGNAL Processing, DSP), field-Programmable gate array (Field-Programmable GATE ARRAY, FPGA), programmable logic array (Programmable Logic Array, PLA). The processor 110 may integrate one or a combination of several of a central processing unit (Central Processing Unit, CPU), an image processor (Graphics Processing Unit, GPU), a modem, etc. The CPU mainly processes an operating system, a user page, an application program and the like; the GPU is used for being responsible for rendering and drawing of display content; the modem is used to handle wireless communications. It will be appreciated that the modem may not be integrated into the processor 110 and may be implemented solely by a single communication chip.

In order to ensure that different third party application programs can achieve better operation effects, the operating system allocates corresponding system resources for the different third party application programs. However, the requirements of different application scenarios in the same third party application program on system resources are different, for example, under the local resource loading scenario, the third party application program has higher requirement on the disk reading speed; in the animation rendering scene, the third party application program has higher requirements on the GPU performance. The operating system and the third party application program are mutually independent, and the operating system often cannot timely sense the current application scene of the third party application program, so that the operating system cannot perform targeted system resource adaptation according to the specific application scene of the third party application program.

In order to enable the operating system to distinguish specific application scenes of the third-party application program, data communication between the third-party application program and the operating system needs to be communicated, so that the operating system can acquire current scene information of the third-party application program at any time, and targeted system resource adaptation is performed based on the current scene.
