Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the invention provides a control method for improving comfort of an air conditioner and a control device 100 for improving comfort of the air conditioner, which are applied to an air conditioner 10, such as a constant frequency air conditioner, and can improve comfort of the constant frequency air conditioner. The air conditioner 10 includes a memory 11, a processor 12, and a control device 100 for improving comfort of the air conditioner.
The memory 11 and the processor 12 are electrically connected to each other directly or indirectly to enable data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The control device 100 of the air conditioner 10 for improving comfort of the air conditioner includes at least one software function module which may be stored in the memory 11 in the form of software or firmware (firmware) or solidified in an Operating System (OS) of a server. The processor 12 is configured to execute executable modules stored in the memory 11, for example, software functional modules included in the control device 100 for improving air conditioning comfort, a control program capable of running on the processor 12 for improving air conditioning comfort, and the like.
The Memory 11 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read Only Memory (PROM) 11, an Erasable Read Only Memory (EPROM), an electrically Erasable Read Only Memory (EEPROM), and the like. The memory 11 is used for storing a program, and the processor 12 executes the program after receiving an execution instruction.
Referring to fig. 2, the control method for improving the comfort of the air conditioner includes the following steps.
Step S100: receives a cooling command of the air conditioner 10.
It should be noted that the cooling command is used to control the air conditioner 10 to operate in the cooling mode. The cooling command may include controlling the air conditioner 10 to be turned on in a cooling mode, or switching the air conditioner 10 being operated to a cooling mode, such as switching the air conditioner 10 being operated in a ventilation mode to a cooling mode.
Step S200: the throttle device of the air conditioner 10 is controlled to the maximum opening degree in response to the cooling command.
The adjusting time can be saved when the throttling device is in the maximum opening degree, and the adjusting efficiency of the throttling device is improved. Alternatively, the throttle device of the air conditioner 10 may be an electronic expansion valve, and in this case, the electronic expansion valve is controlled to the maximum opening degree in step S200: when the air conditioner 10 is opened in the cooling mode, the electronic expansion valve is opened at the maximum opening degree; when the air conditioner 10 is switched to the cooling mode, the electronic expansion valve is adjusted to the maximum opening degree.
Step S300: indoor temperature data and set temperature data are received.
The indoor temperature data represents an actual temperature of the room where the air conditioner 10 is located, and the set temperature data represents a target temperature set by the air conditioner 10. Room temperature data may be obtained by sensors. The set temperature data may be set by a user or by system default, such as when the air conditioner 10 is turned on in a cooling mode.
In addition, it should also be noted that the indoor temperature data may be acquired after the air conditioner 10 is operated for a certain period of time, for example, after the compressor of the air conditioner 10 is operated for 10 seconds, and then the indoor temperature data is received
Step S400: differential temperature data is calculated.
It should be noted that, when the indoor temperature data is greater than or equal to the set temperature data, the air conditioner 10 can adjust the indoor temperature data to be close to the set temperature data when the cooling mode is operated, for example, the indoor temperature data is 30 ℃ (celsius), the set temperature data is 25 ℃, and the air conditioner 10 starts the cooling mode to adjust the indoor temperature data 30 ℃ to the set temperature data of 25 ℃. The difference temperature data is a difference value obtained by subtracting the set temperature data from the indoor temperature data, and represents a difference between the indoor temperature data and the set temperature data, for example, the indoor temperature data takes a value of 30 ℃, the set temperature data takes a value of 25 ℃, and at this time, the difference temperature data is: 30-25 deg.C to 5 deg.C.
It should be noted that step S400 may be executed after the air conditioner 10 is operated for a certain period of time, for example, after the air conditioner is operated in the cooling mode for one minute.
Step S500: and judging whether the difference temperature data is greater than or equal to zero.
It should be noted that, in step S500, the judgment of whether the difference temperature data is greater than or equal to zero means whether the difference between the indoor temperature data and the set temperature data is greater than or equal to zero. It is noted that "zero" here may have a certain error, such as the error is set to be ± 0.2, etc.
If the difference temperature data is greater than or equal to zero, step S600 is performed. Otherwise, the step S300 is continued or the operation is ended.
Step S600: the rotational speed of the external fan of the air conditioner 10 is controlled to be constant or increased, and the opening degree of the throttle device of the air conditioner 10 is controlled to be decreased so that the indoor temperature data is stabilized to the set temperature data.
In step S600, the rotation speed of the external fan of the air conditioner 10 is controlled to be constant or increased, and the opening degree of the throttle device of the air conditioner 10 is controlled to be decreased so that the indoor temperature data is stabilized to the set temperature data. It should be noted that "stabilizing the indoor temperature data to the set temperature data" herein does not only mean that the indoor temperature data is equal to the set temperature data, but that the indoor temperature data is within a certain error range of the set temperature data, for example, if the temperature difference between the indoor temperature data and the set temperature data is within 0.1 ℃, the indoor temperature data is considered to be stabilized to the set temperature data. For example, the set temperature data is 25 ℃, and if the indoor temperature data is 24.9 ℃, the indoor temperature data of 24.9 ℃ is considered to be stabilized to the set temperature data of 24.9 ℃. In addition, since the indoor temperature data dynamically changes with time, it can also be considered that the indoor temperature data is stabilized at the set temperature data when the temperature difference between the indoor temperature data and the set temperature data in a continuous period of time is within the error range, for example, if the temperature differences between a plurality of sets of indoor temperature data received within 2 minutes and the set temperature data are within the error range, it is considered that the indoor temperature data is stabilized at the set temperature data.
In addition, it should be noted that in step S600, the rotation speed of the external fan of the air conditioner 10 needs to be controlled to be constant or increased, and the rotation speed of the external fan should be less than or equal to the maximum rotation speed of the external fan of the air conditioner 10. For example, for an external fan of the air conditioner 10 with a maximum rotation speed of 900 rpm, the rotation speed of the external fan controlled in step S600 is less than or equal to 900 rpm.
Referring to fig. 3, in further embodiments of the present invention, step S600 may include sub-step S610 and sub-step S620.
Substep S610: and judging whether the difference temperature data is less than the first preset temperature and greater than or equal to the second preset temperature.
It should be noted that, both the first preset temperature and the second preset temperature are greater than zero, and the substep S610 is configured to determine whether the difference temperature data is between the first preset temperature and the second preset temperature. For example, when the first preset temperature is 5 ℃, the second preset temperature is 1 ℃, and Td represents the difference temperature data, the sub-step S610 can be expressed as: judging whether Td is more than or equal to 1 ℃ and less than 5 DEG C
If the difference temperature data is less than the first predetermined temperature and greater than or equal to the second predetermined temperature, substep S620 is performed.
Substep S620: the rotation speed of the external fan of the air conditioner 10 is controlled to increase, and the opening degree of the throttle device of the air conditioner 10 is controlled to decrease.
Further, in other embodiments of the present invention, sub-step S610 may further include sub-step S611 and sub-step S612, and sub-step S620 may further include sub-step S621 and sub-step S622.
Substep S611: and judging whether the difference temperature data is less than the first preset temperature and greater than or equal to a third preset temperature.
It should be noted that the third preset temperature is greater than the second preset temperature, and the third preset temperature is less than the first preset temperature, that is, the third preset temperature is between the first preset temperature and the second preset temperature. The third predetermined temperature divides the interval in the substep S610 into two, one of which is a difference temperature data smaller than the first predetermined temperature and greater than or equal to the third predetermined temperature, and the other of which is a difference temperature data smaller than the third predetermined temperature and greater than or equal to the second predetermined temperature. For example, the first preset temperature is 5 ℃, the second preset temperature is 1 ℃, the third preset temperature is 3 ℃, and the substep S611 can be expressed as follows: judging whether Td is more than or equal to 3 ℃ and less than 5 ℃ or not.
If the difference temperature data is less than the first predetermined temperature and greater than or equal to the third predetermined temperature, the sub-step S621 is performed: the rotation speed of the external fan of the air conditioner 10 is controlled to increase by a first number of revolutions per minute, and the opening degree of the throttle device of the air conditioner 10 is controlled to decrease by a first number of steps per minute.
Substep S612: and judging whether the difference temperature data is less than a third preset temperature and greater than or equal to a second preset temperature.
It should be noted that at least one of the substeps S611 and the substep S612 is satisfied, that is, if the difference temperature data is less than the first preset temperature and greater than or equal to the second preset temperature, and the third preset temperature is between the first preset temperature and the second preset temperature, the difference temperature data either satisfies that the difference temperature data is less than the first preset temperature and greater than or equal to the third preset temperature, or satisfies that the difference temperature data is less than the third preset temperature and greater than or equal to the second preset temperature. For example, the first preset temperature is 5 ℃, the second preset temperature is 1 ℃, the third preset temperature is 3 ℃, if Td is greater than or equal to 1 ℃ and less than 5 ℃, at least one of the two formulas of Td is greater than or equal to 3 ℃ and less than 5 ℃ and Td is greater than or equal to 1 ℃ and less than 3 ℃, wherein Td represents difference temperature data.
When the second preset temperature takes a value of 1 ℃ and the third preset temperature takes a value of 3 ℃, the substep S612 can be expressed as: judging whether Td is more than or equal to 1 ℃ and less than 3 ℃ or not.
If the difference temperature data is less than the third predetermined temperature and greater than or equal to the second predetermined temperature, the sub-step S622 is performed: the rotation speed of the external fan of the air conditioner 10 is controlled to increase by a second number of revolutions per minute, and the opening degree of the throttle device of the air conditioner 10 is controlled to decrease by a second number of steps per minute.
The second number of revolutions is smaller than the first number of revolutions, and the first number of steps is larger than the second number of steps. It should be noted that, in each of the above-mentioned sub-steps S621 and S622, the rotation speed of the external fan of the air conditioner 10 is controlled to increase and the opening degree of the throttle device of the air conditioner 10 is controlled to decrease, the difference temperature data when the sub-step S611 is established is larger than the difference temperature data when the sub-step S612 is established, and when the sub-step S611 is established, the sub-step S621 is executed, and when the sub-step S612 is established, the sub-step S622 is executed. The sub-steps S621 and S622 are respectively configured to control the rotation speed of the external fan of the air conditioner 10 to increase and control the opening degree of the throttling device of the air conditioner 10 to decrease, that is, when the difference temperature data is larger, the rotation speed of the external fan per minute increases more, and the opening degree of the throttling device decreases more. For example, the first revolution value is 25 (i.e., the rotation speed of the outer fan is increased by 25 revolutions per minute), the second revolution value is 2 (i.e., the rotation speed of the outer fan is increased by 2 revolutions per minute), the first step value is 10 (i.e., the opening degree of the throttle device is decreased by 10 steps per minute), and the second step value is 1 (i.e., the opening degree of the throttle device is decreased by 1 step per minute).
Further, in some other embodiments of the present invention, step S600 may further include sub-step S630 and sub-step S640.
Substep S630: it is determined whether the real-time rotational speed of the external fan of the air conditioner 10 is equal to the maximum rotational speed of the external fan of the air conditioner 10.
It should be noted that, in the above step S620, the rotation speed of the external fan needs to be increased, and the sub-step S630 is used to determine whether the external fan of the air conditioner 10 is operating within the maximum rotation speed range. For example, the maximum rotation speed of the outer fan is 900 rpm, and the sub-step S630 may be expressed as: it is determined whether the real-time speed of the external fan of the air conditioner 10 is equal to 900 rpm.
In addition, it should also be noted that the real-time rotation speed of the external fan of the air conditioner 10 may be directly obtained or may be measured by a sensor. The real-time rotation speed may be obtained at intervals, i.e. the sub-step S630 is performed at intervals, such as every 10 minutes.
If the real-time rotational speed of the external fan of the air conditioner 10 is equal to the maximum rotational speed of the external fan of the air conditioner 10, the sub-step S640 is performed.
Substep S640: the outer fan of the air conditioner 10 is controlled to maintain the maximum rotation speed of the outer fan of the air conditioner 10.
That is, if the rotation speed of the outer fan of the air conditioner 10 is increased to the maximum rotation speed of the outer fan, the outer fan is operated at the maximum rotation speed. At this time, the opening degree of the throttle device can be adjusted to improve comfort.
In some other embodiments of the present invention, step S600 may further include sub-step S650. If the difference temperature data is greater than or equal to zero, then substep S650 is performed.
Substep S650: the external fan of the air conditioner 10 is controlled to operate at a set rotation speed, and the throttle device of the air conditioner 10 is controlled to reduce the set number of steps per minute.
It should be noted that the difference between the sub-step S650 and the sub-steps S621 and S622 is that the external fan of the air conditioner 10 is controlled to operate at the set rotation speed in the sub-step S650, and the external fan of the air conditioner 10 is controlled to increase the first rotation speed or the second rotation speed per minute in the sub-steps S621 and S622. That is, the rotational speed of the outer fan is constantly operated in the sub-step S650, and the rotational speed of the outer fan is varied with time in the sub-steps S621 and S622.
Further, sub-step S650 may further include sub-step S651, sub-step S652, and sub-step S653.
Substep S651: and judging whether the difference temperature data is greater than a first preset temperature or not, or whether the difference temperature data is greater than or equal to zero and less than a second preset temperature or not.
It should be noted that the first preset temperature is greater than zero, and the second preset temperature is less than the first preset temperature. It should be noted that the first preset temperature and the second preset temperature may be the same as or different from the first preset temperature and the second preset temperature in the sub-step S610. Furthermore, in some embodiments of the present invention, substep S650 may be combined with substep S610 described above.
The set rotating speed comprises a first set rotating speed and a second set rotating speed, the set step number comprises a first set step number and a second set step number, and the second set step number is smaller than the first set step number. If the difference temperature data is greater than the first predetermined temperature, the sub-step S652 is executed: controlling an external fan of the air conditioner 10 to operate at a first set rotation speed, and controlling a throttle device of the air conditioner 10 to reduce a first set number of steps per minute; if the difference temperature data is greater than or equal to zero and less than the second predetermined temperature, the sub-step S653 is performed: the external fan of the air conditioner 10 is controlled to operate at a second set rotational speed and the throttle device of the air conditioner 10 is controlled to decrease at a second set number of steps per minute.
For example, the first preset temperature is 5 ℃, the second preset temperature is 1 ℃, and Td is more than or equal to 5 ℃ when substep S652 is executed; in performing substep S653, 0 ℃. ltoreq. Td < 1 ℃, where Td represents the difference temperature data.
It should be noted that the difference temperature data when the sub-step S652 is executed is larger than the difference temperature data when the sub-step S653 is executed, and the first set number of steps of the sub-step S652 is larger than the second set number of steps of the sub-step S653, which means that the opening degree of the throttle device decreased per minute is also larger when the difference temperature data is larger. For example, the first set step number is 180 (i.e., the opening degree of the throttle device is decreased by 180 steps per minute), and the second set step number is 0.1 (i.e., the opening degree of the throttle device is decreased by 1 step per ten minutes). In the sub-step S652, the difference between the indoor temperature data and the set temperature data is large, and the opening degree decreased per minute needs to be set to a large value to rapidly increase the cooling capacity, thereby improving the comfort. In sub-step S653, the difference between the room temperature data and the set temperature data is small, the room temperature data has substantially stabilized at the set temperature data, and the adjustment of the opening degree of the throttle device is also small.
In summary, the control method for improving the comfort of the air conditioner according to the embodiment of the present invention can control the rotation speed of the external air blower of the air conditioner 10 and reduce the opening degree of the throttling device of the air conditioner 10 according to the difference between the indoor temperature data and the set temperature data, that is, the difference temperature data, so as to ensure the comfort of the air conditioner 10 and improve the cooling efficiency.

In the embodiment of the present invention, the step S100 is executed by the first receiving module 110.
And the response module 120 is used for responding to the refrigeration instruction to control the throttling device of the air conditioner 10 to be opened at the maximum opening degree.
In the embodiment of the present invention, the step S200 is executed by the response module 120.
