On the other hand, when the air conditioner is in refrigerant pump mode, humidification demand is determined based on outdoor temperature, air conditioner load rate, and the humidification efficiency of the humidification film. This allows the air conditioner to enter refrigerant pump mode earlier during transitional seasons, reducing compressor operating time and further improving air conditioner energy efficiency.

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0060] Figure 1 This is a front view structural diagram of an air conditioning unit in one embodiment of this application. Figure 2 This is a top view of the air conditioning unit in one embodiment of this application. Please refer to... Figure 1 and Figure 2 The air conditioning unit includes an exhaust fan 1, a water distributor 2, a humidifying membrane 3, a circulating pump 4, a condenser 5, a bypass valve 6, a temperature and humidity detection module 7, a refrigerant pump assembly 8, a compressor assembly 9, a blower 10, and an evaporator 11.

[0061] During hot seasons, the air conditioner operates in compressor mode. The compressor assembly 9 compresses the low-temperature, low-pressure gas flowing through the evaporator 11 into high-temperature, high-pressure refrigerant gas, which is then discharged to the outdoor condenser 5. The high-temperature, high-pressure refrigerant gas exchanges heat with the outdoor cold air through the condenser 5, thus obtaining a room-temperature, high-pressure refrigerant liquid. After being throttled and depressurized by a throttling valve (not shown in the figure), it flows through the evaporator 11 to exchange heat with the indoor circulating hot air. The heat-absorbing, evaporating refrigerant gas, becoming low-temperature, low-pressure refrigerant gas, is then compressed again by the compressor assembly 9. This cycle continues, dissipating indoor heat to the outdoor environment. To reduce the energy consumption of the compressor assembly 9, the outdoor air can be humidified and cooled. Specifically, the circulation pump 4 pressurizes the water in the water tank (not shown in the figure) and delivers it to the water distributor 2. The water distributor 2 has a built-in flow equalization device, ensuring that the circulating water is evenly sprayed onto the humidifying film 3. The outdoor air is isenthalpically cooled after flowing through the humidifying film 3. The cooled outdoor air then passes through the condenser 5, thus providing the condenser 5 with its heat exchange capacity.

[0062] During cold seasons, the air conditioner operates in refrigerant pump mode. The power system is the refrigerant pump assembly 8, which is connected to the liquid outlet of the condenser 5. The condensed liquid is transported to the evaporator 11, where the high-temperature refrigerant gas, after absorbing heat and evaporating, flows back through the condenser 5, indirectly exchanging heat with the cold outdoor air, and then condenses back into a low-temperature liquid. This cycle continues, dissipating indoor heat to the outdoor environment.

[0063] This application provides an air conditioning control method that can be applied to the air conditioner or air conditioning unit described above. The executing entity of this air conditioning control method can be a control module installed in the air conditioner. Optionally, the control module may include a processor and a memory, used to control the coordinated operation of various components of the air conditioner.

[0064] Figure 3 This is a flowchart illustrating an air conditioning control method in one embodiment of this application. Please refer to... Figure 3 The air conditioning control method may include steps S100 and S200.

[0065] S100: If the relative humidity of the outdoor air is less than or equal to the preset relative humidity, the humidification requirement will be determined based on the outdoor temperature and the air conditioner's operating mode.

[0066] S200: Controls the opening of the humidification membrane according to humidification needs.

[0067] The humidification requirement indicates whether humidification is needed, and the operating modes include refrigerant pump mode and compressor mode.

[0068] In some embodiments, the air conditioning unit includes a temperature and humidity detection module located on the outdoor side and behind the humidification membrane, and a pressure detection module located at the liquid outlet of the condenser. Both the temperature and humidity detection module and the pressure detection module are connected to the control module. The control module can obtain the relative humidity RH and outdoor temperature T of the outdoor air through the temperature and humidity detection module. If the relative humidity RH of the outdoor air detected by the temperature and humidity detection module is greater than the preset relative humidity RH1, it indicates that there is no humidification requirement, the humidification membrane does not work, the bypass valve is opened, and the outdoor fresh air flows directly through the bypass valve and the condenser. If the relative humidity RH of the outdoor air detected by the temperature and humidity detection module is less than or equal to the preset relative humidity RH1, it indicates that there is a humidification requirement, that is, the outdoor air needs to be humidified. Specifically, the humidification requirement can be determined according to the outdoor temperature T and the air conditioning operating mode. If step S100 determines that there is a humidification requirement, the control module outputs a humidification control signal to the humidification membrane to control the humidification membrane to open and humidify the outdoor air.

[0069] In step S100, the humidification requirement is determined based on the outdoor temperature and the air conditioner's operating mode, including the following two cases:

[0070] When the air conditioner is operating in compressor mode, the humidification requirement is determined based on the outdoor temperature and condensing pressure; or,

[0071] When the air conditioner is in refrigerant pump mode, the humidification requirement is determined based on the outdoor temperature, the air conditioner's load rate, and the humidification efficiency of the humidification membrane.

[0072] This application embodiment determines humidification demand based on outdoor temperature and the air conditioner's operating mode, and controls the humidification film to open accordingly. On one hand, when the air conditioner is in compressor mode, humidification demand is determined based on outdoor temperature and condensing pressure. The humidification film is then opened to cool the outdoor air, thereby reducing the condensing pressure of the condenser, which in turn reduces compressor energy consumption and improves air conditioner energy efficiency. On the other hand, when the air conditioner is in refrigerant pump mode, humidification demand is determined based on outdoor temperature, air conditioner load rate, and the humidification efficiency of the humidification film. This allows the air conditioner to enter refrigerant pump mode earlier during transitional seasons, reducing compressor operating time and further improving air conditioner energy efficiency. Furthermore, by determining humidification demand through these two methods and controlling the humidification film to open accordingly, automatic humidification control can be achieved, further improving the overall energy efficiency of the air conditioner.

[0073] Figure 4 This is a schematic diagram illustrating the process of determining humidification requirements based on outdoor temperature and condensing pressure in one embodiment of this application. Please refer to... Figure 4 This includes steps S110 and S120.

[0074] S110: Determine the first humidification requirement value based on the outdoor temperature and condensing pressure;

[0075] S120: If the first humidification demand value is greater than the preset demand value, then the humidification demand is determined.

[0076] Specifically, the outdoor temperature T (i.e., the current outdoor temperature) is obtained through the temperature and humidity detection module, and the condensing pressure P (i.e., the current condensing pressure) of the condenser is obtained through the pressure detection module. Based on the outdoor temperature T and the condensing pressure P, a first humidification demand value X1 is determined. The first humidification demand value X1 can be understood as the degree of need for humidifying the outdoor air under the current outdoor temperature T and current condensing pressure P. If the first humidification demand value X1 is greater than a preset demand value, then it is determined that there is a humidification demand, i.e., the outdoor air needs to be humidified.

[0077] Figure 5 This is a flowchart illustrating the process of determining humidification requirements based on outdoor temperature, air conditioning load rate, and humidification efficiency of the humidification film in one embodiment of this application. Please refer to... Figure 5 This includes steps S130 to S150.

[0078] S130: Determine the target temperature based on the load factor;

[0079] S140: Determine the expected temperature after humidification based on the outdoor temperature and the humidification efficiency of the air conditioner's humidification membrane;

[0080] S150: If the target temperature is higher than the expected temperature, determine the humidification requirement.

[0081] Specifically, for air conditioning units, there is a correlation between the load rate and the humidifier film opening temperature T2, and this correlation can be pre-stored in the control module's memory. For example, when the air conditioning unit's load rate is 100%, the humidifier film opening temperature T2 is 9℃; when the air conditioning unit's load rate is 75%, the humidifier film opening temperature T2 is 12℃. The control module can determine the target humidifier film opening temperature (hereinafter referred to as the target temperature) based on the air conditioning unit's current load rate.

[0082] In some embodiments, the humidification efficiency of the air conditioner's humidification film is a given initial value, for example, 70%. The expected temperature T3 after humidification can be determined based on the outdoor temperature T and the humidification efficiency of the air conditioner's humidification film. It is understood that the expected temperature T3 after humidification is lower than the outdoor temperature T. Since operating in compressor mode consumes more energy than operating in refrigerant pump mode, during transitional seasons (seasons transitioning from high-temperature to low-temperature seasons), it is advisable to activate the humidification film to allow the air conditioner to enter refrigerant pump mode earlier, thereby reducing compressor operating time and further improving the overall energy efficiency of the air conditioner. Therefore, during transitional seasons, if the expected temperature T3 has not yet been reached (i.e., it is lower than the target temperature T2), or if the target temperature T2 is higher than the expected temperature T3, it can also be determined that there is a need for humidification, i.e., the outdoor air needs to be humidified, thereby reducing compressor operating time and further improving the overall energy efficiency of the air conditioner.

[0083] In this embodiment, on one hand, a first humidification demand value is determined based on the outdoor temperature and condensing pressure. If the first humidification demand value is greater than a preset demand value (humidification demand threshold), the humidification film is activated to cool the outdoor air, thereby reducing the condensing pressure of the condenser, and thus reducing compressor energy consumption and improving air conditioning energy efficiency. On the other hand, a target temperature is determined based on the load rate, and the expected temperature after humidification is determined based on the outdoor temperature and humidification efficiency. If the expected temperature after humidification is less than or equal to the target temperature (humidification film activation temperature), the humidification film is activated to cool the outdoor air. This allows the air conditioner to enter refrigerant pump mode earlier during transitional seasons, thereby reducing compressor running time and further improving air conditioning energy efficiency. Furthermore, by determining the humidification demand through the above two methods and outputting a humidification control signal to control the humidification film activation based on the humidification demand, automatic indoor humidification control can be achieved, avoiding over-humidification and further improving the overall energy efficiency of the air conditioner. Combining the above embodiments, the humidification film can be activated in different ways in different seasons to improve the overall energy efficiency of the air conditioner.

[0084] Figure 6 This is a flowchart illustrating step S110 in one embodiment of this application. Please refer to... Figure 6 In some embodiments, step S110, determining the first humidification requirement value based on the outdoor temperature and condensing pressure, includes:

[0085] Step S111: Obtain the preset outdoor temperature and the preset condensing pressure of the condenser;

[0086] Step S112: Determine the second humidification requirement value based on the difference between the outdoor temperature and the preset outdoor temperature;

[0087] Step S113: Determine the third humidification requirement value based on the difference between the condensing pressure and the preset condensing pressure;

[0088] Step S114: Determine the larger of the second humidification demand value and the third humidification demand value as the first humidification demand value.

[0089] In some embodiments, a preset outdoor temperature T1 and a preset condensing pressure P1 of the condenser can be obtained and stored in the control module. For example, in water-scarce areas, the preset outdoor temperature T1 can be set to 30°C and the preset condensing pressure P1 can be set to 26 bar; in water-rich areas, the preset outdoor temperature T1 can be set to 15°C and the preset condensing pressure P1 can be set to 24 bar. The settings vary depending on the air conditioning operating mode. It is understood that for water-scarce areas, the preset outdoor temperature T1 and preset condensing pressure P1 are higher than in water-rich areas. Therefore, the difference between the outdoor temperature and the preset outdoor temperature, and the difference between the condensing pressure and the preset condensing pressure, are smaller than in water-rich areas. Consequently, the determined second and third humidification demand values ​​are smaller than in water-rich areas, thus effectively conserving water resources in water-scarce areas.

[0090] Optionally, the second humidification demand value X2 has a corresponding relationship or formula with the difference between the outdoor temperature T and the preset outdoor temperature T1. It can be understood that the higher the outdoor temperature T, the greater the difference between the outdoor temperature T and the preset outdoor temperature T1, and thus the greater the need to activate the humidification membrane, i.e., the larger the second humidification demand value X2. Similarly, the third humidification demand value X3 has a corresponding relationship or formula with the difference between the condenser's condensing pressure P and the preset condensing pressure P1. It can be understood that the higher the condenser's condensing pressure P, the greater the difference between the condenser's condensing pressure P and the preset condensing pressure P1, and thus the greater the need to activate the humidification membrane, i.e., the larger the third humidification demand value X3.

[0091] Preferably, determining the larger of the second humidification demand value X2 and the third humidification demand value X3 as the first humidification demand value X1 can maximize the satisfaction of humidification requirements. In practical applications, either the second humidification demand value X2 or the third humidification demand value X3 can also be determined as the first humidification demand value X1. This way, only one of the second humidification demand value X2 and the third humidification demand value X3 needs to be obtained, thereby reducing the computational load on the control module.

[0092] Figure 7 This is a flowchart illustrating step S140 in one embodiment of this application. Please refer to... Figure 7 In some embodiments, step S140, calculating the expected temperature after humidification based on the outdoor temperature value and the humidification efficiency of the air conditioner's humidification film, includes:

[0093] S141: Determine the wet-bulb temperature based on relative humidity and outdoor temperature;

[0094] S142: Determine the expected temperature using the following formula:

[0095] Expected temperature = Outdoor temperature - (Outdoor temperature - Wet bulb temperature) * Humidification efficiency.

[0096] In some embodiments, the wet-bulb temperature is determined based on the relative humidity RH and the outdoor temperature T, and then the expected temperature T3 is determined using the formula T3 = T - (T - wet-bulb temperature) * humidification efficiency.

[0097] Alternatively, the wet-bulb temperature can be determined directly using a wet-bulb thermometer instead of through calculation.

[0098] Figure 8A and Figure 8B This is a flowchart illustrating an air conditioning control method in another embodiment of this application.

[0099] Please refer to Figure 8A In some embodiments, the air conditioning control method further includes:

[0100] S300: Responds to water-saving operation commands and determines the first humidification demand value based on outdoor temperature and condensing pressure;

[0101] S400: Controls the opening degree of the air conditioner's bypass valve based on the first humidification demand value.

[0102] or,

[0103] Please refer to Figure 8B In some embodiments, the air conditioning control method further includes:

[0104] S500: Responds to water-saving operation commands and determines the target temperature based on the load rate;

[0105] S600: Determines the fourth humidification requirement value based on the difference between the target temperature and the outdoor temperature and the adjustment sensitivity;

[0106] S700: Controls the opening degree of the air conditioner's bypass valve according to the fourth humidification demand value.

[0107] In some embodiments, in response to a water-saving operation command, a first humidification demand value X1 can be determined based on the outdoor temperature and condensing pressure, and the opening degree of the bypass vent valve of the air conditioner can be controlled based on the first humidification demand value.

[0108] Alternatively, it can respond to water-saving operation commands and determine the target temperature based on the load rate. Then, the fourth humidification demand value X4 is determined using the following formula:

[0109] Fourth humidification requirement x4 = (Target temperature - Outdoor temperature) / Adjustment sensitivity * 100%

[0110] Determine the difference between the target temperature T2 and the outdoor temperature T, then divide it by the adjustment sensitivity, and multiply by 100% to obtain the fourth humidification demand value X4. The adjustment sensitivity can be understood as the adjustment range; for example, if the target temperature T2 is within the adjustment sensitivity range, no adjustment is needed. Alternatively, a PID algorithm can be used to determine the fourth humidification demand value X4.

[0111] In some embodiments, a water-saving button can be provided on the air conditioner remote control. When a user wants to save water, they can press the water-saving button. The air conditioner's control module responds to the water-saving operation command, determining and outputting an opening control signal for controlling the opening degree of the air conditioner's bypass ventilation valve based on a first humidification demand value or a fourth humidification demand value (preferably the larger of the first and second humidification demand values). Optionally, the opening control signal can also be determined and output based on either the first or fourth humidification demand value.

[0112] When the bypass vent valve is open, due to the resistance of the humidification membrane, most of the outdoor air will preferentially flow through the bypass vent valve to the condenser, reducing the amount of outdoor air passing through the humidification membrane. This reduces the water consumption of the humidification membrane, achieving water conservation. It's understandable that since the opening control signal is determined based on the first and fourth humidification demand values, even when the bypass vent valve is open, it's under the premise of meeting the maximum humidification demand. Therefore, it doesn't reduce the overall energy efficiency of the air conditioner while still achieving water conservation.

[0113] Optionally, the magnitude of the opening control signal can have a corresponding relationship or formula with the larger of the first humidification demand value and the fourth humidification demand value.

[0114] Understandably, in areas or seasons with abundant water, the bypass ventilation valve can be set to a closed state by default, only opening via a water-saving button when water conservation is needed. This increases the adaptability of the air conditioning equipment; furthermore, the default closure of the bypass ventilation valve reduces the bypass ventilation volume, further lowering the temperature of the humidified air and achieving energy savings.

[0115] This application also provides an air conditioning control device. The air conditioning control device includes:

[0116] The first determining module is used to determine the humidification requirement based on the outdoor temperature and the air conditioner's operating mode if the relative humidity of the outdoor air is less than or equal to the preset relative humidity. The humidification requirement indicates whether humidification is needed. The operating modes include refrigerant pump mode and compressor mode.

[0117] The control module is used to control the opening of the humidification membrane according to the humidification requirements;

[0118] Specifically, the control module is used for:

[0119] When the air conditioner is operating in compressor mode, the humidification requirement is determined based on the outdoor temperature and condensing pressure; or,

[0120] When the air conditioner is in refrigerant pump mode, the humidification requirement is determined based on the outdoor temperature, the air conditioner's load rate, and the humidification efficiency of the humidification membrane.

[0121] The air conditioning control device in this embodiment determines the humidification demand based on the outdoor temperature and the air conditioner's operating mode, and controls the humidification membrane to open according to the humidification demand. On one hand, when the air conditioner is in compressor mode, the humidification demand is determined based on the outdoor temperature and condensing pressure, and the humidification membrane is opened to cool the outdoor air, thereby reducing the condensing pressure of the condenser, and thus reducing compressor energy consumption and improving air conditioning energy efficiency. On the other hand, when the air conditioner is in refrigerant pump mode, the humidification demand is determined based on the outdoor temperature, the air conditioner's load rate, and the humidification efficiency of the humidification membrane. This allows the air conditioner to enter refrigerant pump mode earlier during transitional seasons, thereby reducing compressor running time and further improving air conditioning energy efficiency. Furthermore, by determining the humidification demand through the above two methods and controlling the humidification membrane to open according to the humidification demand, automatic humidification control can be achieved, thus better improving the overall energy efficiency of the air conditioner.
