[0029] Figure 1 is a schematic diagram of an air conditioner 10 according to an embodiment of the present invention.

[0030] refer to Figure 1 As shown, the air conditioner 10 of this embodiment includes two evaporators 12 and two heaters 14. Figure 1 The air supply duct inside the air conditioner 10 is not shown, but the evaporator 12 and the heater 14 are divided into two groups by a dotted frame in the figure. It can be understood that one evaporator 12 and one heater 14 in each group are arranged in the same air supply duct. The two air supply ducts are independent of each other inside the air conditioner 10, that is, the air flow after passing through the evaporator 12 of each air supply duct will not exchange air flow between the two air supply ducts. The heater 14 is located downstream of the air supply direction of the evaporator 12 and is usually arranged at the air outlet. Generally speaking, an air supply fan is also arranged in each air supply duct, and each air supply fan is usually arranged at a position between the evaporator 12 and the heater 14 in the respective air supply duct, and when working, it promotes the formation of an air supply airflow that passes through the evaporator 12 and the heater 14 in sequence and then blows out the air conditioner 10.

[0031] The two evaporators 12 are connected to the compressor 18 and the condenser 20 of the air conditioner 10 through the refrigerant pipeline. In some optional embodiments, an electric three-way valve 16 is provided at the intersection of the refrigerant pipelines of the two evaporators 12. By controlling the passage of the electric three-way valve 16, the refrigerant can be controlled to flow through one or two evaporators 12, thereby adjusting the working quantity of the evaporator 12. In some optional embodiments, the air conditioner 10 has both cooling and heating functions. By setting a four-way reversing valve 24 in the refrigerant pipeline, the working mode of the air conditioner 10 can be adjusted between the cooling mode and the heating mode. A throttling device 22 is also provided in the refrigerant pipeline. It can be understood that when the air conditioner 10 switches the working mode to the heating mode, the two evaporators 12 play the role of exothermic heating rather than heat absorption cooling.

[0032] Figure 2 1 is a flow chart of a dehumidification control method of an air conditioner 10 according to an embodiment of the present invention.

[0033] refer to Figure 2 As shown, the dehumidification control method of the air conditioner 10 generally includes:

[0034] Step S202: receiving a dehumidification instruction;

[0035] Step S204: obtaining the detected temperature of the working environment of the air conditioner 10, and calculating the temperature difference between the detected temperature and the set temperature of the air conditioner 10;

[0036] Step S206: adjusting the working quantity of the evaporator 12 and the heater 14 according to the size of the temperature difference.

[0037] According to the dehumidification control method of this embodiment, after receiving the dehumidification instruction, the air conditioner 10 will adjust the temperature according to the detected temperature T of the working environment. R The set temperature T of the air conditioner 10 S The temperature difference R T (R T =T R -T S ), adjust the working quantity of the evaporator 12 and the heater 14. In each air supply duct, since the working temperature of the evaporator 12 is significantly lower than the temperature of the ambient air flowing through it, the moisture in the air will be pre-condensed on the surface of the evaporator 12, so the humidity of the air flow passing through the evaporator 12 is reduced. However, when the humidity is reduced, the temperature of the air flow is also reduced due to the influence of the evaporator 12. In order to avoid the air flow temperature blown out by the air conditioner 10 being inappropriate, the heater 14 located downstream of the evaporator 12 in the air supply direction can increase the air outlet temperature of the air conditioner 10, so that no matter how high or low the detected temperature is, the air conditioner 10 can blow out an air flow with a suitable temperature to adjust the ambient temperature, and will not cause an excessive drop in the ambient temperature due to dehumidification.

[0038] Specifically, in some optional embodiments, according to the temperature difference R T The steps of adjusting the working quantity of the evaporator 12 and the heater 14 include: T When the temperature is less than a preset first temperature threshold T1, one evaporator 12 is controlled to operate, and one or two heaters 14 are controlled to operate.

[0039] Furthermore, in some optional embodiments, according to the temperature difference R T The step of adjusting the working quantity of the evaporator 12 and the heater 14 also includes: T When the temperature is greater than a preset first temperature threshold T1, the two evaporators 12 are controlled to operate, and the two heaters 14 are controlled not to operate.

[0040] The preset value of the first temperature threshold T1 can be 2 to 4°C, and can generally be set to 4°C. T When it is greater than the first temperature threshold T1, it indicates that the current detected temperature T of the working environment of the air conditioner 10 R Much higher than the set temperature T of the air conditioner 10 S Therefore, in order to reduce the ambient temperature while dehumidifying, both evaporators 12 of the air conditioner 10 can be controlled to work. T When it is less than the first temperature threshold T1, it indicates that the current detected temperature T of the working environment of the air conditioner 10 is R Approaching or falling below the set temperature T of the air conditioner 10 S However, in order to maintain the dehumidification function, it is still necessary to control one evaporator 12 to work. In order to neutralize the cold provided by the evaporator 12 and increase the temperature of the air flow blown out by the air conditioner 10, it is necessary to control one or two heaters 14 to work accordingly.

[0041] On this basis, in some further embodiments, at a temperature difference R T When the temperature difference R is less than the preset first temperature threshold T1, the steps of controlling one evaporator 12 to work and controlling one or two heaters 14 to work include: T When the temperature difference R is greater than the preset second temperature threshold T2 and less than the first temperature threshold T1, one evaporator 12 is controlled to work, and one heater 14 is controlled to work; T When the temperature is less than the second temperature threshold T2, one evaporator 12 is controlled to operate, and two heaters 14 are controlled to operate.

[0042] The preset value of the second temperature threshold T2 can be -2 to 0°C, and can generally be set to 0°C. TWhen the temperature is greater than the second temperature threshold T2 and less than the first temperature threshold T1, it indicates that the current detected temperature T of the working environment of the air conditioner 10 is R Approaching the set temperature T of the air conditioner 10 S , that is, the ambient temperature is at a relatively suitable temperature. In order to maintain the ambient temperature while dehumidifying, when controlling one evaporator 12 to work, only one heater 14 needs to be controlled to work to neutralize the cooling provided by the evaporator 12. T When the temperature is less than the second temperature threshold T2, it indicates that the ambient temperature is relatively low and needs to be raised. Therefore, while controlling one evaporator 12 to work, the two heaters 14 are also controlled to work to raise the ambient temperature.

[0043] Figure 3 is based on Figure 2 The flowchart of adjusting the working quantity of the evaporator 12 and the heater 14 in the dehumidification control method of the air conditioner 10 shown is a detailed flowchart of step S206 in the above embodiment.

[0044] refer to Figure 3 As shown, the dehumidification control method of the air conditioner 10 also includes:

[0045] Step S2062: Determine the temperature difference R T and the magnitude of the first temperature threshold T1 and the second temperature threshold T2;

[0046] In R T > In the case of T1, step S2064 is executed: the two evaporators 12 are controlled to work, and the two heaters 14 are controlled not to work;

[0047] When T2<R T When <T1, execute step S2066: control one evaporator 12 to work, and control one heater 14 to work;

[0048] In R T When <T2, step S2068 is executed: one evaporator 12 is controlled to operate, and two heaters 14 are controlled to operate.

[0049] In particular, in some optional embodiments, based on the execution of step S2066, the air conditioner 10 further controls the evaporator 12 and the heater 14 located in the same air supply duct to work. In other words, an evaporator 12 and a heater 14 in working state are located in the same air supply duct. Since the evaporator 12 and the heater 14 in working state are located in the same air supply duct, the air flow in this duct will be cooled by the evaporator 12 and heated by the heater 14 in turn, and the temperature when it is finally blown out of the air conditioner 10 is relatively close to the ambient temperature, and the air supply airflow temperatures blown out of the two air supply ducts are also similar, and will not cause discomfort to the user even if it is blown directly.

[0050] In the above embodiment, during the period of adjusting the working quantity of the evaporator 12 and the heater 14, the two air supply ducts of the air conditioner 10 both supply air at the same air supply speed, that is, even under certain circumstances, the evaporator 12 and the heater 14 in one of the air supply ducts are not working, the air supply duct still supplies air at the same air supply speed as the other air supply duct.

[0051] Based on the dehumidification control method of the air conditioner 10 in the above embodiment, the air conditioner 10 can reasonably control the supply air temperature while adjusting the humidity. Even if the air conditioner 10 is in a cold and humid working environment, it can increase the ambient temperature while dehumidifying and maintain the ambient temperature within a relatively comfortable range.

[0052] On this basis, the air conditioner 10 can further adjust the frequency of the compressor 18 and the air supply speed to improve the dehumidification efficiency of the air conditioner 10.

[0053] Figure 4 FIG. 1 is a flow chart of a dehumidification control method of an air conditioner 10 according to another embodiment of the present invention.

[0054] refer to Figure 4 As shown, the dehumidification control method of the air conditioner 10 includes:

[0055] Step S402: receiving a dehumidification instruction;

[0056] Step S404: obtaining the detected temperature of the working environment of the air conditioner 10, and calculating the temperature difference between the detected temperature and the set temperature of the air conditioner 10;

[0057] Step S406: adjusting the working quantity of the evaporator 12 and the heater 14 according to the size of the temperature difference;

[0058] Step S408: obtaining the detected humidity of the working environment of the air conditioner 10, and calculating the humidity difference between the detected humidity and the set humidity of the air conditioner 10;

[0059] Step S410: adjusting the frequency and air supply speed of the compressor 18 of the air conditioner 10 according to the size of the humidity difference.

[0060] According to the control method of this embodiment, after the step of adjusting the working quantity of the evaporator 12 and the heater 14 according to the size of the temperature difference, the dehumidification control method of the air conditioner 10 further includes: obtaining the detected humidity H of the working environment of the air conditioner 10 R , and calculate the detection humidity H R The air conditioner 10 sets the humidity H S Humidity difference R H (R H =H R -H S );According to humidity difference R H The size of the compressor 18 of the air conditioner 10 is adjusted to adjust the frequency and air supply speed.

[0061] It should be noted that before executing the step of adjusting the frequency and air supply speed of the compressor 18 of the air conditioner 10, that is, during the process of adjusting the working number of the evaporator 12 and the heater 14, the two air supply ducts of the air conditioner 10 both supply air to the outside at a preset air supply speed, and the compressor 18 also works at a frequency corresponding to the working number of the evaporator 12.

[0062] In some optional embodiments, the adjustment of the working quantity of the evaporator 12 and the heater 14 will be performed after the temperature difference is greater than the second temperature threshold and less than the first temperature threshold, that is, after the temperature difference is greater than the second temperature threshold and less than the first temperature threshold, and the air conditioner 10 adjusts the evaporator 12 and the heater 14 accordingly, the air conditioner 10 starts to adjust the compressor 18 frequency and the air supply speed of the air conditioner 10 according to the size of the humidity difference.

[0063] The air conditioner 10 can adjust the frequency of the compressor 18 and the air supply speed in the following manner. In some optional embodiments, according to the humidity difference R H The steps of adjusting the frequency and air supply speed of the compressor 18 of the air conditioner 10 include: H When the humidity is greater than a preset first humidity threshold H1, the frequency of the compressor 18 is increased, and the air supply velocity of the air supply duct where the evaporator 12 in the working state is located is reduced.

[0064] At the same time, in some optional embodiments, according to the humidity difference R H The step of adjusting the frequency and air supply speed of the compressor 18 of the air conditioner 10 also includes: H When the humidity is greater than a preset second humidity threshold H2 and less than a first humidity threshold H1, the frequency of the compressor 18 is controlled to remain unchanged, and the air supply speeds of the two air supply ducts are controlled to remain unchanged.

[0065] The first humidity threshold H1 may be preset in the range of 5% to 10%, for example, 5%, and the second humidity threshold H2 is usually 0. H When the humidity difference R is greater than the first humidity threshold H1, it indicates that the ambient humidity is too high, so it is necessary to improve the dehumidification efficiency of the air conditioner 10. By increasing the frequency of the compressor 18 and reducing the wind speed, on the one hand, the temperature of the working evaporator 12 can be reduced to improve the condensation efficiency of the water, and on the other hand, the water in the airflow passing through the evaporator 12 can be condensed more fully. H Between the first humidity threshold H1 and the second humidity threshold H2, it indicates that the ambient humidity is only relatively high, and the air conditioner 10 only needs to maintain dehumidification.

[0066] Figure 5 is based on Figure 4 The flowchart of adjusting the frequency and air supply speed of the compressor 18 of the air conditioner 10 in the dehumidification control method of the air conditioner 10 is a schematic diagram of the detailed flowchart of step S410 in the above embodiment.

[0067] refer to Figure 5 As shown, the dehumidification control method of the air conditioner 10 also includes:

[0068] Step S4102: Determine humidity difference R H and the magnitude of the first humidity threshold H1 and the second humidity threshold H2;

[0069] In R H >H1, execute step S4104: increase the frequency of the compressor 18, and reduce the air supply speed of the air supply duct where the evaporator 12 in the working state is located;

[0070] When H2<R H When

[0071] In particular, in the above step S4104, the air conditioner 10 only reduces the air supply speed of the air supply duct where the evaporator 12 in the working state is located, that is, when only one evaporator 12 is in the working state, then only the air supply speed in the air supply duct on this side is reduced, while the air supply speed of the air supply duct on the side where the evaporator 12 is not in the working state remains unchanged.

[0072] And based on the above embodiment, in some optional implementations, the humidity difference R H ​The greater the difference from the first humidity threshold H1, the greater the frequency of the compressor 18, and the smaller the air supply velocity of the air supply duct where the evaporator 12 in the working state is located. H The difference between the humidity threshold H1 and the first humidity threshold H1 adjusts the frequency and air supply speed of the compressor 18, which can ensure the dehumidification efficiency of the air conditioner 10 while making the air supply speed and the temperature of the air supply air flow of the air conditioner 10 more suitable, and will not be affected by the humidity difference R H Just slightly exceeding the first humidity threshold H1 causes a sudden drop in the supply air velocity and a significant cooling of the supply air flow.

[0073] In addition, in some optional implementations, the air conditioner 10 will also record the current operating parameters after receiving the dehumidification instruction, and then H When the temperature is lower than H2, the dehumidification is stopped and the operating parameters are automatically adjusted to the operating parameters when the dehumidification command is received. The operating parameters of the air conditioner 10 include various parameter information such as the operating mode, the air supply temperature, the air supply speed, and the swing state.

[0074] Figure 6 is a schematic block diagram of an air purification device according to an embodiment of the present invention.

[0075] refer to Figure 6 As shown, the air conditioner 10 has Figure 1 In addition to the two evaporators 12 and the two heaters 14, the air conditioner 10 further includes a control module 30. The control module includes a processor 32 and a memory 34, wherein the memory 34 stores a control program, and when the control program is executed by the processor 32, it is used to implement any of the above-mentioned dehumidification control methods of the air conditioner 10.

[0076] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention.
