Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
The air conditioner performs functions such as refrigeration/heating circulation or dehumidification through the compressor, the condenser, the expansion valve and the evaporator, can realize the regulation of the indoor environment, and improves the comfort of the indoor environment. The refrigeration cycle includes a series of processes, for example, involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
In the related art, in order to realize a constant temperature dehumidification function, an indoor electric heating device is usually controlled to be turned on or a refrigerant device is usually added to the air conditioner. However, the use cost is increased by adopting the electric heating mode, and the mode of adding the refrigerant device is not suitable for some air-conditioning products due to limited space or limited product cost, so that the application range is small.
In order to solve the above problem, an embodiment of a first aspect of the present invention provides an air conditioner.
As shown in fig. 1, the air conditioner 100 includes a compressor 1, a reversing device 2, an outdoor heat exchanger 3, an outdoor fan 4, an indoor fan 5, a first throttling device 6, a second throttling device 7, a first indoor heat exchanger 8, a second indoor heat exchanger 9, and a control module 10 (not shown in the figure).
The first indoor heat exchanger 8, the second throttling device 7 and the second indoor heat exchanger 9 are sequentially connected in series between the reversing device 2 and the first throttling device 6; and the control module 10 is configured to obtain an indoor ambient temperature, determine that a temperature difference between the indoor ambient temperature and a set temperature is smaller than a preset temperature difference, and execute a reheating dehumidification mode, wherein the first throttling device 6 is controlled to be fully opened and the second throttling device 7 is controlled to start throttling, the compressor 1 is controlled to operate at an initial set frequency, the outdoor fan 4 is controlled to operate at an initial set rotational speed, the indoor fan 5 is controlled to operate at a user set rotational speed, the time that the compressor 1 operates at the initial set frequency reaches a first preset duration, the operating frequency of the compressor is adjusted according to the indoor ambient temperature and the set temperature, the time that the outdoor fan 4 operates at the initial set rotational speed reaches a second preset duration, and the rotational speed of the outdoor fan 4 is adjusted according to the outdoor coil temperature.
Specifically, as shown in fig. 1, the first indoor heat exchanger 8 and the second indoor heat exchanger 9 are arranged in a tandem arrangement, air is supplied from the second indoor heat exchanger 9 side, and air is discharged from the first indoor heat exchanger 8 side. When the air conditioner operates in a reheating dehumidification mode, high-temperature and high-pressure gaseous refrigerant is discharged to the reversing device 2 from an exhaust port of the compressor 1, the gaseous refrigerant is cooled by the outdoor heat exchanger 3 and enters the first indoor heat exchanger 8 for heat dissipation after passing through the fully-opened first throttling device 6, then the refrigerant is throttled by the second throttling device 7 to become low-temperature and low-pressure liquid refrigerant, and the liquid refrigerant is subjected to heat absorption in the second indoor heat exchanger 9 to become the low-temperature and low-pressure gaseous refrigerant and returns to the compressor 1, so that a reheating cycle is completed.
Wherein, in the reheating dehumidification mode, the first indoor heat exchanger 8 exchanges heat between the flowing refrigerant and the indoor air, the temperature of the refrigerant reaching the second throttling device 7 is reduced, the opening degree of the second throttling device 7 is adjusted, and the temperature of the refrigerant entering the second indoor heat exchanger 9 is further reduced, that is, when the air conditioner operates in the reheating dehumidification mode, the second indoor heat exchanger 9 is a low-temperature evaporator, the first indoor heat exchanger 8 is a high-temperature condenser, the indoor inlet air exchanges heat with the second indoor heat exchanger 9 to reduce the ambient temperature, the indoor water vapor is separated out in the form of condensed water to achieve the effects of cooling and dehumidification, and become cool air with low humidity, and the temperature of the cool air can be raised through the first indoor heat exchanger 8, so that the inlet air temperature is close to or raised with the outlet air temperature, and the indoor ambient temperature is maintained at a certain temperature, the effect of constant temperature dehumidification is realized.
In addition, the air conditioner adjusts the operating frequency of the compressor 1 through the indoor environment temperature and the set temperature in the process of operating the reheating dehumidification mode, so that when the indoor environment temperature is lower than the set temperature, the operating frequency of the compressor 1 can be controlled to be increased to improve the air outlet temperature, or when the indoor environment temperature is higher than the set temperature, the operating frequency of the compressor 1 can be controlled to be reduced to reduce the air outlet temperature, and therefore the purpose of improving the air outlet temperature is achieved, the indoor environment temperature is maintained at the set temperature, and the constant temperature effect is achieved.
Meanwhile, in the process, the rotating speed of the outdoor fan 4 is regulated by the temperature of the outdoor coil, so that when the temperature of the outdoor coil is higher, the pressure of the refrigerant in the system is higher, the rotating speed of the outdoor fan 4 is controlled to be increased, the pressure of the refrigerant in the system is reduced, and the problem that the reheating and dehumidifying mode is stopped due to shutdown protection caused by overhigh pressure is solved, or when the temperature of the outdoor coil is higher, the pressure of the refrigerant in the system is lower, the rotating speed of the outdoor fan 4 is controlled to be reduced, the pressure of the refrigerant in the system is improved, and therefore, the purpose of adjusting the pressure of the refrigerant in the air conditioner is achieved, and the constant-temperature dehumidifying function is normally realized.
The second throttling device 7 is powered on only when the reheat dehumidification mode is executed, and has throttling effect, and the second throttling device 7 is not powered on and has no throttling effect under other conditions.
For example, when the air conditioner 100 operates in the cooling mode, a high-temperature and high-pressure gaseous refrigerant is discharged from an exhaust port of the compressor 1 to the reversing device 2, is condensed by the outdoor heat exchanger 3 to become a low-temperature and high-pressure liquid refrigerant, is throttled by the first throttling device 6 to become a low-temperature and low-pressure liquid refrigerant, and enters the first indoor heat exchanger 8, the second throttling device 7 and the second indoor heat exchanger 9 in sequence, in the process, the low-temperature and low-pressure liquid refrigerant absorbs heat to become a low-temperature and low-pressure gaseous refrigerant, and then returns to the compressor 1 to complete a cooling cycle. Wherein the second throttling means 7 is not powered on and has no throttling effect.
And when the air conditioner operates in a heating mode, high-temperature and high-pressure refrigerant is discharged from an exhaust port of the compressor 1 to the reversing device 2 and then sequentially passes through the second indoor heat exchanger 9, the second throttling device 7 and the first indoor heat exchanger 8, the high-temperature and high-pressure refrigerant is condensed into low-temperature and high-pressure liquid refrigerant, then the low-temperature and high-pressure liquid refrigerant is throttled by the first throttling device 6 and enters the outdoor heat exchanger 3, and the low-temperature and high-pressure liquid refrigerant returns to the compressor 1 after being evaporated and absorbed heat, so that a heating cycle is completed. Wherein the second throttling means 7 is not powered on and has no throttling effect.
According to the air conditioner 100 of the embodiment of the present invention, based on the air conditioner structure described above, the control module 10 controls the air conditioner to execute the reheating and dehumidifying mode without starting the electric heating or setting the three-pipe system, so that the constant temperature dehumidifying effect can be achieved, and the air conditioner 100 has a wider applicability and is more suitable for the air duct type unit. And, in the operation reheating dehumidification mode process, through adjusting the operating frequency of compressor 1 with indoor ambient temperature and set temperature, also can improve the air-out temperature, avoid the air-out temperature to reduce, reach the effect of maintaining constant temperature, simultaneously, adjust the rotational speed of outdoor fan 4 with outdoor coil pipe temperature, can improve the refrigerant pressure in the air conditioner, avoid appearing because of the shutdown protection that the pressure takes place too high, normally realize the constant temperature dehumidification function.
In some embodiments, as shown in fig. 1, the first indoor heat exchanger 8 and the second indoor heat exchanger 9 are arranged side by side in an opposite manner, and a preset interval is provided between the first indoor heat exchanger 8 and the second indoor heat exchanger 9.
Wherein, be relative mode setting based on first indoor heat exchanger 8 and second indoor heat exchanger 9, both are in the state that is parallel to each other, both can make whole indoor air intakes get into second indoor heat exchanger 9, in order to cool down the dehumidification, then heat up entering first indoor heat exchanger 8, thereby can effectively avoid air outlet department the phenomenon of condensation to appear, can make the area of contact of indoor heat exchanger and air intake bigger again, improve heat exchange efficiency, and set up suitable clearance between first indoor heat exchanger 8 and the second indoor heat exchanger 9 and predetermine the interval promptly, thereby effectively avoid indoor cold and hot air to mix when guaranteeing dehumidification effect, reach better constant temperature dehumidification effect.
In some embodiments, the predetermined interval may range from 5mm to 10mm, for example, the predetermined interval may be 5mm, 6mm, 7mm, 9mm, or 10 mm. The preset interval cannot be too large so as to avoid the influence on the constant-temperature dehumidification effect caused by mixing cold air and hot air in the room; the preset interval cannot be too small, and the dehumidification effect is easy to reduce due to too small interval, so that the embodiment of the invention adopts the preset interval range to achieve a better constant-temperature dehumidification effect.
An embodiment of a second aspect of the present invention provides a control method for an air conditioner in the above embodiment, and as shown in fig. 2, the control method at least includes steps S1-S4.
In step S1, the indoor ambient temperature is acquired.
Specifically, the indoor ambient temperature may be detected by a temperature sensor provided on an indoor unit of the air conditioner, for example, as shown in fig. 1, a temperature sensor 21 may be provided on the second indoor heat exchanger 9 side to detect the indoor ambient temperature and send the detected indoor ambient temperature to the control module of the air conditioner, or by another device in the room that can acquire the indoor ambient temperature, send the detected indoor ambient temperature to the control module of the air conditioner through the communication module.
In step S2, it is determined that a first temperature difference between the indoor ambient temperature and the set temperature is less than a first preset temperature difference.
The set temperature may be a temperature set by a user, for example, the user sets the temperature through a remote controller or a set key of an air conditioner APP on the mobile terminal, or sets the temperature through an operation mode such as a language and a key through an operation panel on the air conditioner body; alternatively, the set temperature may be an optimum temperature that is automatically set by the air conditioner according to actual conditions and that meets user comfort.
And, considering the conditions of the detection precision of the temperature sensor, the placement position of the temperature sensor, and the like, the embodiment of the present invention presets the allowable error temperature, that is, the first preset temperature difference, which may be preset according to the actual situation without limitation, for example, the first preset temperature difference is 2 ℃.
Specifically, whether a first temperature difference between the indoor environment temperature and the set temperature is smaller than a first preset temperature difference is judged, if the first temperature difference is smaller than the first preset temperature difference, the current indoor environment temperature is relatively stable, and therefore, in order to maintain the indoor environment temperature near the set temperature, the air conditioner is controlled to execute a reheating dehumidification mode, so that the indoor environment temperature is continuously maintained near the set temperature while dehumidification is performed; if the first temperature difference is not smaller than the first preset temperature difference, the current indoor environment temperature is not stable, and therefore the air conditioner is controlled to operate in a cooling mode or a heating mode to adjust the air outlet temperature of the air conditioner, so that the indoor environment temperature is reduced or increased to the set temperature, the indoor environment temperature is maintained near the set temperature while dehumidification is carried out, and a comfortable indoor environment is achieved.
And step S3, executing a reheating dehumidification mode, wherein the first throttling device is controlled to be fully opened, the second throttling device is controlled to start throttling, the compressor is controlled to operate at an initial set frequency, the outdoor fan is controlled to operate at an initial set rotating speed, and the indoor fan is controlled to operate at a user set rotating speed.
The initial setting frequency can be a frequency value set based on experience, the compressor is controlled to operate by the frequency value, the outlet air temperature can be enabled to be equal to or close to the dehumidification setting temperature more quickly, and the dehumidification efficiency is improved. The initially set rotation speed may be an empirically set rotation speed value, and the operation of the outdoor fan is controlled by the rotation speed value, so that the compressor can operate within a normal working pressure range to ensure the normal completion of the reheating and dehumidifying mode. The rotation speed set by the user can be a rotation speed value set by the user through a remote controller or an air conditioner APP on the mobile terminal or an operation panel of the air conditioner.
Specifically, when the air conditioner executes a reheating dehumidification mode, the first throttling device is controlled to be fully opened, the second throttling device is controlled to start throttling, the compressor is controlled to operate at an initial set frequency, the outdoor fan is controlled to operate at an initial set rotating speed, the indoor fan is controlled to operate at a user set rotating speed, constant-temperature dehumidification is achieved through the two indoor heat exchangers shown in the figure 1, and user experience is improved.
And step S4, the time of the compressor running at the initial set frequency reaches a first preset time, the running frequency of the compressor is adjusted according to the indoor environment temperature and the set temperature, the time of the outdoor fan running at the initial set rotating speed reaches a second preset time, and the rotating speed of the outdoor fan is adjusted according to the outdoor coil temperature.
The first preset time period may be a time threshold set based on experience, and when the operation time period of the compressor reaches the first preset time period, it may be determined that the compressor has operated stably, and the outlet air temperature of the air conditioner also reaches a stable state, for example, the first preset time period is 1 minute. The second preset time period may be a time threshold set based on experience, and when the operation time period of the outdoor fan reaches the second preset time period, it may be determined that the outdoor fan has operated stably and the pressure of the refrigerant in the air conditioner is also stable, for example, the second preset time period is 1 minute.
Specifically, since the operating frequency of the compressor and the indoor environment temperature have a certain relationship, the higher the frequency of the compressor is, the higher the outlet air temperature of the air conditioner is, and thus the indoor environment temperature is also increased; otherwise, the indoor ambient temperature is lowered. Therefore, when the compressor runs at the initial set frequency for a first preset time, the running frequency of the compressor is adjusted according to the indoor environment temperature and the set temperature, so that the air outlet temperature of the air conditioner is adjusted, the indoor environment temperature is maintained at the set temperature, and the constant temperature effect is achieved.
And because the shutdown protection is triggered when the pressure of the refrigerant in the air conditioner is too high or too low, the reheating dehumidification mode is stopped, therefore, the refrigerant pressure in the system is judged according to the temperature of the outdoor coil, and the refrigerant pressure is higher when the temperature of the outdoor coil is higher, and is smaller when the temperature of the outdoor coil is lower. Furthermore, when the time that the outdoor fan operates at the initial set rotating speed reaches a second preset time, the rotating speed of the outdoor fan is adjusted according to the temperature of the outdoor coil, so that when the temperature of the outdoor coil is too high, the rotating speed of the outdoor fan is increased, the temperature of the outdoor coil is reduced, the pressure of a refrigerant in the system is further reduced, or when the temperature of the outdoor coil is too low, the rotating speed of the outdoor fan is reduced, the temperature of the outdoor coil is increased, the pressure of the refrigerant in the system is further increased, therefore, the purpose of adjusting the pressure of the refrigerant in the air conditioner is achieved, and the normal completion of a reheating dehumidification mode is ensured.
According to the control method of the air conditioner provided by the invention, two indoor heat exchangers, namely a first indoor heat exchanger and a second indoor heat exchanger, are arranged in an indoor unit, and the first indoor heat exchanger, a second throttling device and the second indoor heat exchanger are sequentially connected between a reversing device and a first throttling device in series, when the air conditioner executes a reheating dehumidification mode, a refrigerant flowing through the first indoor heat exchanger exchanges heat with indoor air, the temperature of the refrigerant reaching the second throttling device is reduced, and the temperature of the refrigerant entering the second indoor heat exchanger is further reduced, namely, when the reheating dehumidification mode is operated, the second indoor heat exchanger is a low-temperature evaporator, the first indoor heat exchanger is a high-temperature condenser, indoor inlet air exchanges heat with the second indoor heat exchanger to achieve the effects of temperature reduction and dehumidification to become cool air with low humidity, and then the cool air can promote the temperature through first indoor heat exchanger for the air inlet temperature is close with the air-out temperature or promotes, thereby realizes the effect of constant temperature dehumidification, and at this in-process, both need not to open the electrical heating, also need not to set up the three-pipe system, therefore the suitability is wider, also more is applicable to the tuber pipe formula unit machine. And in the process of operating the reheating dehumidification mode, the operation frequency of the compressor is adjusted by the indoor environment temperature and the set temperature, the air outlet temperature can be improved, the air outlet temperature is prevented from being reduced, the constant temperature maintaining effect is achieved, meanwhile, the rotating speed of the outdoor fan is adjusted by the outdoor coil temperature, the pressure of a refrigerant in the air conditioner can be improved, the shutdown protection caused by overhigh pressure is avoided, and the constant temperature dehumidification function is normally realized.
In some embodiments, when the reheating dehumidification mode is operated, the compressor is controlled to operate at 45Hz, and the outdoor fan is controlled to operate at 300 rpm, so that a constant-temperature dehumidification effect can be realized more quickly, the indoor environment temperature is effectively maintained at a set temperature while dehumidification is performed, the dehumidification time is shortened, and the dehumidification efficiency is improved.
In some embodiments, the compressor run time is controlled for 1 minute while the reheat dehumidification mode is operated; when the indoor environment temperature is lower than the set temperature, the indoor environment temperature is reduced, and in order to keep the constant temperature effect, the operation frequency of the compressor is controlled to be increased by 10Hz so as to improve the air outlet temperature of the air conditioner and the indoor environment temperature; when the indoor environment temperature is equal to the set temperature, the indoor environment temperature is maintained at a comfortable temperature, and the running frequency of the compressor is controlled to be kept unchanged in order to keep the constant temperature; when the indoor environment temperature is higher than the set temperature, the indoor environment temperature is increased, and in order to keep the constant temperature effect, the operation frequency of the compressor is controlled to be reduced by 10Hz, so that the air outlet temperature is reduced, and the indoor environment temperature is reduced. Therefore, by the control mode, the constant temperature effect can be effectively achieved while dehumidification is carried out, the operating frequency of the compressor is adjusted by taking 10Hz as a reference, the indoor environment temperature can be adjusted to be close to the set temperature more quickly, and the user experience is improved.
