DETAILED DESCRIPTION

[0036] In order to enable persons skilled in the art to more fully understand the features and technical content of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below with reference to the accompanying drawings, which are used only for reference and do not limit the embodiments of the present application. In the following technical description, in order to facilitate explanation, a plurality of details are provided to provide a full understanding of the disclosed embodiments. However, one or more embodiments can still be implemented without these details. In other cases, well-known structures and devices can be simplified to facilitate the drawings.

It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0038] Unless otherwise specified, the term "a plurality of" means two or more.

[0039] In the embodiments of the present application, the character " / " represents an "or" relationship between the objects before and after it. For example, A / B represents: A or B.

[0040] The term "and / or" is a description of the association relationship between objects, which means that there can be three relationships. For example, A and / or B means: A or B, or, A and B, the three relationships.

[0041] In the embodiments of the present application, the latent heat type air conditioner refers to an air conditioner with the function of handling latent heat, which can improve the refrigeration efficiency of the air conditioner, and is especially suitable for high-temperature and high-humidity application scenarios. The latent heat type air conditioner in the embodiments of the present application can be a split air conditioner or a packaged air conditioner.

[0042] Figure 1 is a structural schematic diagram of a latent heat type air conditioner provided by the embodiments of the present application. The same as the conventional air conditioner, the latent heat type air conditioner also includes a compressor 10, an evaporator 20 and a condenser 30, the compressor 10 is connected with the condenser 30, the condenser 30 is connected with the evaporator 20, and the evaporator 20 is connected with the compressor 10 again, the compressor 10 provides high-temperature and high-pressure gaseous refrigerant to the condenser 30, the gaseous refrigerant is condensed and liquefied in the condenser 30 and releases heat, forming liquid refrigerant; the liquid refrigerant flows into the evaporator 20, evaporates and vaporizes in the evaporator 20 and absorbs heat, forming gaseous refrigerant, and the gaseous refrigerant is recovered by the compressor 10 again.

[0043] In addition, in combination with Figure 1As shown, the latent heat type air conditioner includes a latent heat treatment device 40, a heating device 50, and a cooling device 60. The latent heat treatment device 40 absorbs moisture from the indoor air during the moisture absorption process and releases the moisture to the outside during the regeneration process. The heating device 50 has a first receiving cavity 51, which contains a heat exchanger 52 and a first fluid. One end of the heat exchanger 52 is connected to the outlet of the compressor 10, and the other end is connected to the condenser 30. The first fluid is used to heat the latent heat treatment device 40. Figure 1 The arrow between the heating device 50 and the latent heat treatment device 40 indicates the direction of heat flow, causing the latent heat treatment device 40 to perform a regeneration process; the cooling device 60 is provided with a second receiving cavity 61, and the second receiving cavity 61 is provided with a second fluid, which is used to cool the latent heat treatment device 40. Figure 1 The arrow between the cooling device 60 and the latent heat treatment device 40 indicates the direction of heat flow, causing the latent heat treatment device 40 to perform a moisture absorption process.

[0044] The aforementioned latent heat treatment device 40 can perform a moisture absorption process and a regeneration process. During the moisture absorption process, the latent heat treatment device 40 absorbs moisture from the air, causing the moisture content in the air to decrease and the moisture content in the latent heat treatment device 40 to increase. During the regeneration process, the latent heat treatment device 40 releases moisture into the air, causing the moisture content in the air to increase and the moisture content in the latent heat treatment device 40 to decrease.

[0045] The latent heat treatment device 40 may include zeolite, silica gel, activated carbon, or organic polymer materials that are hydrophilic or water-absorbing.

[0046] In this embodiment, the latent heat treatment device 40 absorbs moisture from the indoor air to reduce its moisture content, and then releases moisture into the outdoor air to further reduce its moisture content, preparing for the next moisture absorption process. For example, the latent heat treatment device 40 includes a first circulating air path 41, a second circulating air path 42, and a fan 43. The inlet and outlet of the first circulating air path 41 are located indoors, while the inlet and outlet of the second circulating air path 42 are located outdoors. The fan 43 provides aerodynamic power to the first circulating air path 41 and the second circulating air path 42, allowing air to pass through either the first or second circulating air path 41 after the fan 43 is started.

[0047] In the dehumidification process of the latent heat treatment device 40, the fan 43 is turned on, the first circulating air path 41 is connected, and the second circulating air path 42 is disconnected. Under the action of the fan 43, indoor air passes through the latent heat treatment device 40 and returns to the indoor environment. In the process of air circulation, the latent heat treatment device 40 absorbs moisture in the air, thereby reducing the moisture content in the air. In the dehumidification process of the latent heat treatment device 40, the fan 43 is turned on, the first circulating air path 41 is disconnected, and the second circulating air path 42 is connected. Under the action of the fan 43, outdoor air passes through the latent heat treatment device and returns to the outdoor environment. The moisture in the latent heat treatment device 40 is carried into the outdoor environment by the outdoor air, preparing for the next dehumidification process.

[0048] The first fluid in the above-mentioned heating device 50 can be water or chilled brine. The second fluid in the above-mentioned cooling device 60 can also be water or chilled brine.

[0049] In the latent heat type air conditioner provided in the embodiments of the present application, the cooling device 60 can cool the latent heat treatment device 40, thereby enabling the latent heat treatment device 40 to have dehumidification capacity. The refrigerant at the outlet of the compressor 10 is first used to heat the heat exchanger 52 in the heating device 50, so that the heating device 50 has the capacity to heat the latent heat treatment device 40, thereby enabling the latent heat treatment device 40 to have regeneration capacity. In this way, multiple heat exchangers 52 with alternating switching functions are not required to simultaneously remove indoor sensible heat and indoor latent heat, thereby reducing the number of heat exchangers 52 and the complexity of the refrigerant pipeline, and reducing the production cost of the air conditioner.

[0050] At the same time, in the refrigeration process, the heat generated by the condenser 30 is "waste heat". In the embodiments of the present application, the heat generated by the condenser 30 is applied to the regeneration process of the latent heat treatment device 40, thereby effectively utilizing the heat generated by the condenser 30 and improving the energy efficiency ratio of the air conditioner.

[0051] In the process of cooling the indoor environment by the air conditioner, the indoor temperature and the set temperature are obtained, and the greater the temperature difference between the indoor temperature and the set temperature, the greater the operating frequency of the compressor 10. In combination with the technical solutions in the embodiments of the present application, the greater the operating frequency of the compressor 10, the higher the pressure of the refrigerant provided by the compressor 10 to the heat exchanger 52, and the higher the temperature of the heat exchanger 52, and the higher the temperature of the first fluid, and the higher the temperature of the first fluid, the faster the temperature rising rate of the latent heat treatment device 40 in the temperature rising process; at the same time, the higher the temperature of the first fluid, the greater the maximum amplitude of the temperature change of the latent heat treatment device 40, and in the temperature lowering process, the temperature difference between the temperature of the latent heat treatment device 40 and the temperature of the temperature lowering device 60 can also be maintained to be large, so as to improve the temperature lowering speed. In this way, the temperature rising rate of the latent heat treatment device 40 and the temperature lowering rate of the latent heat device are improved, and the rate of the latent heat treatment device 40 in treating latent heat is improved, that is, even if the room with high humidity is cooled, the better latent heat treatment rate can be maintained, and the energy efficiency ratio of the air conditioner is improved.

[0052] The latent heat type air conditioner in the above embodiments further includes a controller, and the controller executes the control method of the latent heat type air conditioner.

[0053] Figure 2 FIG. 1 is a schematic diagram of a control method of a latent heat type air conditioner provided by an embodiment of the present application. The control method of the latent heat type air conditioner can be executed by a controller of the latent heat type air conditioner, or by a control panel in communication connection with the air conditioner, or by a server in a smart home system.

[0054] In combination with Figure 2 As shown in the figure, the control method of the latent heat type air conditioner includes:

[0055] S201, obtaining a first relative humidity of the indoor environment at a current time.

[0056] For example, the first relative humidity can be obtained by a humidity sensor arranged on the indoor unit of the air conditioner, or by a humidity sensor arranged on other smart devices in the indoor environment, or by a smart humidity sensor arranged in the indoor environment.

[0057] S202, in the case that the first relative humidity is greater than or equal to a first set relative humidity, alternately starting the temperature rising device and the temperature lowering device, so that the latent heat treatment device alternately executes the moisture absorption process and the regeneration process.

[0058] The first set relative humidity is greater than the lower limit of the human comfortable humidity and less than or equal to the upper limit of the human comfortable humidity, and is used to represent the entering condition of removing the indoor latent heat. For example, the first set relative humidity can be 50%, 55% or 60%. The embodiments of the present application do not limit the first set relative humidity, and a person skilled in the art can set the specific first set relative humidity according to the lower limit and the upper limit of the human comfortable humidity of the user.

[0059] The indoor environment is refrigerated by using the technical scheme, the indoor latent heat and the indoor sensible heat can be removed at the same time, and the energy efficiency ratio of the air conditioner is improved.

[0060] Figure 3a is a structural schematic diagram of a latent heat type air conditioner provided by an embodiment of the present application. As shown in Figure 3a , the latent heat type air conditioner further comprises a first circulating pipeline 70, the first circulating pipeline 70 forms a circulating passage between the first containing cavity 51 and the latent heat treatment device 40, and the first circulating pipeline 70 comprises a first pumping unit 71, the first pumping unit 71 is used to make the first fluid circulate and flow in the first circulating pipeline 70. By using the first circulating pipeline 70, the first fluid realizes the temperature rise of the latent heat treatment device 40. In the case that the first fluid is water or frozen brine, the first pumping unit 71 can be a water pump.

[0061] Figure 3b is a structural schematic diagram of a latent heat type air conditioner provided by an embodiment of the present application. As shown in Figure 3b , the latent heat type air conditioner further comprises a second circulating pipeline 80, the second circulating pipeline 80 forms a circulating passage between the second containing cavity 61 and the latent heat treatment device 40, and the second circulating pipeline 80 comprises a second pumping unit 81, the second pumping unit 81 is used to make the second fluid circulate and flow in the second circulating pipeline 80. By using the second circulating pipeline 80, the second fluid realizes the temperature drop of the latent heat treatment device 40. In the case that the second fluid is water or frozen brine, the second pumping unit 81 can be a water pump.

[0062] Figure 3c is a structural schematic diagram of a latent heat type air conditioner provided by an embodiment of the present application. In Figure 3c , the first circulating pipeline 70 and the second circulating pipeline 80 are shown at the same time. In the case that the first pumping unit 71 operates and the second pumping unit 81 stops, the latent heat treatment device 40 performs the dehumidification process; in the case that the first pumping unit 71 stops and the second pumping unit 81 operates, the latent heat treatment device 40 performs the regeneration process.

[0063] Figure 4is a schematic diagram of a control method of a latent heat type air conditioner provided in the embodiments of the present application. The control method of the latent heat type air conditioner can be executed by a controller of the latent heat type air conditioner, or by a control panel in communication connection with the air conditioner, or by a server in a smart home system. The embodiments of the present application exemplarily illustrate the control method of the latent heat type air conditioner applied to the latent heat type air conditioner shown in Figure 3c

[0064] In combination with Figure 4 , the control method of the latent heat type air conditioner comprises:

[0065] S401, obtaining a first relative humidity in a room at a current time.

[0066] S402, in a case that the first relative humidity is greater than or equal to a first set relative humidity, obtaining a first temperature in the room at the current time, and a second temperature and a second relative humidity in the room before the current time.

[0067] Wherein, a temperature difference between the second temperature and the first temperature is within a preset temperature range. For example, the preset temperature range can be 2℃-3℃, 3℃-4℃, 4℃-5℃ or 5℃-6℃.

[0068] Before the current time, a plurality of temperatures and relative humidities at the same time are recorded. The plurality of temperatures before the current time and the corresponding relative humidities can be obtained, a temperature same as a sum of the first temperature and the preset temperature is determined as the second temperature, and a relative humidity corresponding to the temperature same as the sum of the first temperature and the preset temperature is determined as the second relative humidity.

[0069] S403, obtaining a relative humidity difference between the first relative humidity and the second relative humidity.

[0070] S404, adjusting a first pumping rate of a first pumping unit and a second pumping rate of a second pumping unit according to the relative humidity difference, the first relative humidity and a second set relative humidity.

[0071] In a first running, the first pumping rate and the second pumping rate are both default values. In a non-first running, the first pumping rate and the second pumping unit in a last running are adjusted according to the relative humidity difference, the first relative humidity and the second set relative humidity.

[0072] After the first pumping rate of the first pumping unit is changed, a temperature rising rate of the latent heat treatment device will be changed; after the second pumping rate of the second pumping unit is changed, a temperature falling rate of the latent heat treatment device will be changed. In this way, a latent heat removing rate of the latent heat treatment device is changed, and then the relative humidity in the room is changed with the temperature falling.

[0073] ​In the case that the first pumping unit is a water pump, the first pumping rate can be represented by the rotating speed of the water pump; in the case that the second pumping unit is a water pump, the second pumping rate can be represented by the rotating speed of the water pump.

[0074] The first pumping rate and the second pumping rate can be adjusted in the following manner: in the case that the second relative humidity is greater than or equal to the first relative humidity, and the first relative humidity is less than the second set relative humidity, the first pumping rate is reduced according to the relative humidity difference, and the second pumping rate is reduced according to the relative humidity difference.

[0075] The second set relative humidity herein is used to represent the set relative humidity in the room, which can be set by the user himself, or can be the set relative humidity most suitable for the current weather or the current user calculated according to existing big data algorithms or artificial intelligence algorithms.

[0076] The reduction of the first pumping rate and the second pumping rate reduces the rate at which the latent heat treatment device removes the latent heat in the room. As the temperature in the room decreases, the relative humidity in the room tends to increase. Reducing the rate of removing latent heat can reduce the counteraction to the increasing trend of relative humidity, which is conducive to the approach of the relative humidity in the room (the first relative humidity) to the second set relative humidity.

[0077] The first pumping rate and the second pumping rate can be adjusted in the following manner: in the case that the second relative humidity is less than or equal to the first relative humidity, and the first relative humidity is greater than the second set relative humidity, the first pumping rate is increased according to the relative humidity difference, and the second pumping rate is increased according to the relative humidity difference.

[0078] The increase of the first pumping rate and the second pumping rate increases the rate at which the latent heat treatment device removes the latent heat in the room. As the temperature in the room decreases, the relative humidity in the room tends to increase. Increasing the rate of removing latent heat can increase the counteraction to the increasing trend of relative humidity, which is conducive to the approach of the relative humidity in the room (the first relative humidity) to the second set relative humidity.

[0079] In the case that the second relative humidity is greater than or equal to the first relative humidity, and the first relative humidity is greater than the second set relative humidity, the first pumping rate and the second pumping rate can be maintained unchanged, or the first pumping rate and the second pumping rate can be increased, or the first pumping rate and the second pumping rate can be reduced.

[0080] In the case that the second relative humidity is less than or equal to the first relative humidity, and the first relative humidity is less than the second set relative humidity, the first pumping rate and the second pumping rate can be maintained unchanged, or the first pumping rate and the second pumping rate can be increased, or the first pumping rate and the second pumping rate can be reduced.

[0081] Optionally, the lowering the first pumping rate according to the relative humidity difference and the lowering the second pumping rate according to the relative humidity difference comprises: obtaining a first rate positively correlated with the absolute value of the relative humidity difference, and lowering the first pumping rate by the first rate; obtaining a second rate positively correlated with the absolute value of the relative humidity difference, and lowering the second pumping rate by the second rate.

[0082] The absolute value of the relative humidity difference and the first rate can be stored in a database in advance, and the first rate corresponding to the absolute value of the relative humidity difference can be obtained after the relative humidity difference is obtained; similarly, the absolute value of the relative humidity difference and the second rate can be stored in a database in advance, and the second rate corresponding to the absolute value of the relative humidity difference can be obtained after the relative humidity difference is obtained. The difference between the first pumping rate and the first rate can be determined as the adjusted first pumping rate; the difference between the second pumping rate and the second rate can be determined as the adjusted second pumping rate.

[0083] Optionally, the increasing the first pumping rate according to the relative humidity difference and the increasing the second pumping rate according to the relative humidity difference comprises: obtaining a third rate positively correlated with the absolute value of the relative humidity difference, and increasing the first pumping rate by the third rate; obtaining a fourth rate positively correlated with the absolute value of the relative humidity difference, and increasing the second pumping rate by the fourth rate.

[0084] The absolute value of the relative humidity difference and the third rate can be stored in a database in advance, and the third rate corresponding to the absolute value of the relative humidity difference can be obtained after the relative humidity difference is obtained; similarly, the absolute value of the relative humidity difference and the fourth rate can be stored in a database in advance, and the fourth rate corresponding to the absolute value of the relative humidity difference can be obtained after the relative humidity difference is obtained. The sum of the first pumping rate and the third rate can be determined as the adjusted first pumping rate; the sum of the second pumping rate and the fourth rate can be determined as the adjusted second pumping rate.

[0085] Optionally, the adjusting the first pumping rate of the first pumping unit and the second pumping rate of the second pumping unit according to the relative humidity difference, the first relative humidity and the second set relative humidity comprises: obtaining an interval duration from the time corresponding to the second temperature to the current time, and in a case that the interval duration is less than or equal to a first set duration, adjusting the first pumping rate of the first pumping unit and the second pumping rate of the second pumping unit according to the relative humidity difference, the first relative humidity and the second set relative humidity. The interval duration less than or equal to the first set duration indicates that the indoor temperature decreases obviously at this time, and in the case that the indoor temperature decreases obviously, the indoor relative humidity is adjusted according to the above technical solution. In a case that the interval duration is greater than or equal to the first set duration, it indicates that the indoor temperature does not decrease obviously at this time, and other existing technologies can be used for separate dehumidification.

[0086] S405, controlling the first pumping unit and the second pumping unit to alternately operate according to the adjusted first pumping rate and the adjusted second pumping rate.

[0087] The first pumping unit is equivalent to starting the temperature raising device; the second pumping unit is equivalent to starting the temperature lowering device; the first pumping unit and the second pumping unit alternately operate, that is, the latent heat treatment device alternately performs the moisture absorption process and the regeneration process.

[0088] Optionally, the controlling the first pumping unit and the second pumping unit to alternately operate according to the adjusted first pumping rate and the adjusted second pumping rate comprises: alternately controlling the first pumping unit to operate at the adjusted first pumping rate for a second set time length and controlling the second pumping unit to operate at the adjusted second pumping rate for the second set time length.

[0089] Alternatively, the controlling the first pumping unit and the second pumping unit to alternately operate according to the adjusted first pumping rate and the adjusted second pumping rate can comprise: obtaining the weight or the electrical conductivity of the moisture absorption material in the latent heat treatment device; in the case that the weight or the electrical conductivity of the moisture absorption material is greater than or equal to a first set value, closing the second pumping unit, starting the first pumping unit, and switching the latent heat treatment device from the moisture absorption process to the regeneration process; in the case that the weight or the electrical conductivity of the moisture absorption material is less than or equal to a second set value, starting the second pumping unit, closing the first pumping unit, and switching the latent heat treatment device from the regeneration process to the moisture absorption process.

[0090] In the process of reducing the indoor temperature, as the indoor temperature decreases and the absolute humidity in the indoor air decreases, the relative humidity in the room will change in different forms. The relative humidity difference between the second relative humidity and the first relative humidity can reflect the change of the relative humidity in the room, and in combination with the second set relative humidity, the rate of removing latent heat can be adaptively adjusted, and the current relative humidity in the room is adjusted, so as to facilitate the current relative humidity in the room to reach the second set relative humidity.

[0091] Figure 5a is a structural schematic diagram of a latent heat type air conditioner provided by an embodiment of the present application.

[0092] As shown in Figure 5a The latent heat type air conditioner further comprises a third circulating pipeline 90, the third circulating pipeline 90 circulates the second fluid between the surface of the condenser 30 and the second containing cavity 61, and the second fluid cools the condenser 30;

[0094] During the operation of the latent heat type air conditioner, the first fluid in the heating device 50 is heated by the heat exchanger 52 arranged between the compressor 10 and the condenser 30, so that the heating device 50 has the function of heating the latent heat treatment device 40. In this way, the temperature of the condenser 30 can also be reduced. In this case, the condenser 30 can be sprayed by the second fluid in the second containing cavity 61, so that the condenser 30 can be cooled more quickly. Since the temperature of the condenser 30 is relatively low, the temperature of the second fluid in the second containing cavity 61 will not be too high, so that the lower limit temperature of the latent heat treatment device 40 will not be too high, that is, the latent heat treatment device 40 can still maintain a large temperature variation range. In this way, the latent heat treatment device 40 can still maintain a high heating rate or cooling rate, that is, the latent heat treatment device 40 can still achieve a high rate of removing indoor latent heat.

[0096] In combination with FIG. 1, Figure 5b As shown in FIG. 1, the latent heat type air conditioner further comprises a third circulating pipeline 90, and the cooling device 60 further comprises a third containing cavity 62. The third containing cavity 62 is provided with a third fluid, and the third circulating pipeline 90 circulates the third fluid between the surface of the condenser 30 and the third containing cavity 62, so as to cool the condenser 30 by the third fluid.

[0098] Figure 6 FIG. 6 is a schematic diagram of a control method of a latent heat type air conditioner provided by an embodiment of the present application. The control method of the latent heat type air conditioner can be executed by a controller of the latent heat type air conditioner, or by a control panel in communication connection with the air conditioner, or by a server in a smart home system.

[0099] In combination with FIG. 1, Figure 6 As shown in FIG. 6, the control method of the latent heat type air conditioner comprises:

[0100] S601, obtain a third temperature of the condenser surface at the current time, and a fourth temperature of the spraying unit.

[0101] The fourth temperature of the spraying unit here refers to the temperature of the fluid sprayed by the spraying unit. In the case that the spraying unit sprays the second fluid, the temperature of the second fluid in the second containing cavity of the temperature reduction device can be obtained by the temperature sensor arranged in the second containing cavity, and the temperature of the second fluid in the second containing cavity is determined as the fourth temperature of the spraying unit; in the case that the spraying unit sprays the third fluid, the temperature of the third fluid in the third containing cavity of the temperature reduction device can be obtained by the temperature sensor arranged in the third containing cavity, and the temperature of the third fluid in the third containing cavity is determined as the fourth temperature of the spraying unit.

[0102] S602, obtain a first temperature difference between the third temperature and the fourth temperature.

[0103] The first temperature difference between the third temperature and the fourth temperature can be obtained in the case that the third temperature is greater than the fourth temperature.

[0104] Specifically, the difference between the third temperature and the fourth temperature can be determined as the first temperature difference.

[0105] In the case that the third temperature is less than or equal to the fourth temperature, the subsequent steps can not be performed.

[0106] S603, determine the current spraying rate of the spraying unit according to the first temperature difference.

[0107] The current spraying rate of the spraying unit includes the fluid flow rate and / or fluid speed currently sprayed by the spraying unit.

[0108] The current spraying rate of the spraying unit corresponds to the third pumping rate of the third pumping unit.

[0109] The spraying unit can be controlled to spray the fluid (the third fluid or the fourth fluid) to the condenser surface in the process of alternately starting the temperature increasing device and the temperature reduction device (the first relative humidity is greater than or equal to the first set relative humidity), that is, in the process of removing the indoor latent heat; or the spraying unit can also be controlled to spray the fluid to the condenser surface in the case that the first relative humidity is less than the first set relative humidity.

[0110] In the case that the first relative humidity is greater than or equal to the first set relative humidity, the process of reducing the temperature of the condenser by the spraying unit and the process of removing the indoor latent heat by the latent heat treatment device are performed synchronously.

[0111] In combination with the foregoing embodiments, the latent heat type air conditioner can include a compressor, a temperature raising device, and a latent heat treatment device, the temperature raising device is provided with a first containing cavity, the first containing cavity is provided with a heat exchanger and a first fluid, one end of the heat exchanger is communicated with a gas outlet of the compressor, and the other end is communicated with a condenser, and the first fluid is used to raise the temperature of the latent heat treatment device, so that the latent heat treatment device performs a regeneration process.

[0112] On the basis of the structure, the current spraying rate of the spraying unit is determined according to the first temperature difference, including: obtaining a first spraying rate positively related to the first temperature difference; obtaining a fifth temperature of the first fluid; in the case that the fifth temperature does not satisfy a high temperature condition, obtaining a second spraying rate negatively related to the fifth temperature; and determining the current spraying rate according to a rate difference between the first spraying rate and the second spraying rate.

[0113] The fifth temperature of the first fluid does not satisfy the high temperature condition, and the first fluid can continue to be raised in temperature; the lower the fifth temperature, the greater the second spraying rate, and the smaller the rate difference between the first spraying rate and the second spraying rate, so that the current spraying rate is smaller, and the third temperature on the surface of the condenser has a temperature raising trend; since the refrigerant sprayed by the compressor first passes through the heat exchanger and then passes through the condenser, the third temperature on the surface of the condenser is lower than the temperature of the heat exchanger, and the temperature of the heat exchanger does not satisfy the high temperature condition, so the third temperature on the surface of the condenser will not be too high; in the case that the third temperature on the surface of the condenser has a temperature raising trend, the temperature of the heat exchanger also has a temperature raising trend, and the fifth temperature of the first fluid can have a temperature raising trend, which is conducive to maintaining a higher upper limit temperature of the latent heat treatment device, and is conducive to improving the rate at which the latent heat treatment device removes indoor latent heat.

[0114] In addition, in the case that the third pumping unit corresponding to the spraying unit is respectively communicated with the second containing cavity and the spraying unit, the third pumping unit can pump the second fluid in the second containing cavity to the spraying unit, and the spraying unit uses the second fluid to cool the condenser. That is, the second fluid in the second containing cavity of the cooling device can be used to cool the condenser, and can also be used to cool the latent heat treatment device.

[0115] In this case, the current spraying rate of the spraying unit is determined according to the rate difference between the first spraying rate and the second spraying rate, which can reduce the spraying rate of the spraying unit, reduce the amount of second fluid that exchanges heat with the condenser, and further reduce the heat absorbed by the second fluid on the surface of the condenser, which is conducive to maintaining a lower temperature of the second fluid in the second containing cavity of the cooling device, and is conducive to making the latent heat treatment device have a lower lower limit temperature, and further making the second fluid and the latent heat treatment device have a larger temperature difference during the process of cooling the latent heat treatment device, which is conducive to quickly cooling the latent heat treatment device and improving the rate at which the latent heat treatment device removes indoor latent heat.

[0116] The fifth temperature does not meet the high temperature condition, which may include: the fifth temperature is lower than or equal to the first preset temperature.

[0117] Alternatively, in the following cases: the latent heat type air conditioner further includes a cooling device, which has a second receiving cavity containing a second fluid. The second fluid is used to cool the latent heat treatment device, enabling the latent heat treatment device to perform a moisture absorption process; the fifth temperature does not meet the high temperature condition, including: the second temperature difference between the fifth temperature and the sixth temperature of the second fluid is less than or equal to a second preset temperature. In this way, the fifth temperature of the first fluid can have a rising trend, while the sixth temperature of the second fluid can have a falling trend. This is beneficial for maintaining a higher upper limit temperature and a lower lower limit temperature of the latent heat treatment device. During the heating or cooling process of the latent heat treatment device, a higher temperature difference can be maintained between the latent heat treatment device and the first fluid (heating process) or the second fluid (cooling process), which is beneficial for improving the rate at which the latent heat treatment device removes latent heat from the room.

[0118] The above-mentioned determination of the current spray rate based on the rate difference between the first spray rate and the second spray rate may include: determining the rate difference between the first spray rate and the second spray rate as the current spray rate.

[0119] S604. Control the spray unit according to the current spray rate.

[0120] The current spray rate can correspond to the third pumping rate of the third pumping unit. After determining the current spray rate, the third pumping rate of the third pumping unit corresponding to the current spray rate can be determined. Then, the third pumping unit can be controlled according to the third pumping rate to achieve the control of the spraying unit.

[0121] The higher the third temperature on the condenser surface, the greater the first temperature difference. Thus, the first temperature difference reflects the level of the third temperature on the condenser surface. Based on the first temperature difference, the spray unit is controlled to spray the condenser surface, thereby cooling the condenser surface. This helps to lower the internal temperature of the condenser, improve the condensation effect, and further improve the evaporation effect inside the indoor evaporator, thus increasing the cooling efficiency of the air conditioner.

[0122] Figure 7 This is a schematic diagram of a latent heat type air conditioner provided in an embodiment of this application.

[0123] Combination Figure 7 As shown, the latent heat type air conditioner also includes a proportional valve 11. The inlet of the proportional valve 11 is connected to the outlet of the compressor 10, the first outlet of the proportional valve 11 is connected to the heat exchanger 52, and the second outlet of the proportional valve 11 is connected to the condenser 30.

[0124] On the basis of the structure, determining the current spraying rate of the spraying unit according to the first temperature difference can include: obtaining a first spraying rate positively correlated with the first temperature difference; obtaining a first refrigerant flow of the first outlet and a second refrigerant flow of the second outlet; determining a third spraying rate negatively correlated with the first refrigerant flow and positively correlated with the second refrigerant flow according to a corresponding relationship between the refrigerant flow and the spraying rate; and determining the current spraying rate of the spraying unit according to a rate sum of the first spraying rate and the third spraying rate.

[0125] The greater the third spraying rate, the greater the current spraying rate, and the better the cooling effect of the spraying unit on the condenser; the third spraying rate is negatively correlated with the first refrigerant flow, that is, the less the refrigerant flow flowing to the heat exchanger, the worse the cooling effect of the spraying unit on the condenser, which is conducive to improving or maintaining the temperature of the heat exchanger and further improving the rate of removing indoor latent heat by the latent heat treatment device; the third spraying rate is positively correlated with the second refrigerant flow, that is, the more the refrigerant flow flowing to the condenser, the better the cooling effect of the spraying unit on the condenser, which is conducive to following the rate of generating heat by the condenser, adaptively adjusting the cooling effect of the spraying unit on the condenser, and balancing the two, which is conducive to maintaining a stable temperature of the heat exchanger and further enabling the latent heat type air conditioner to have a relatively stable refrigeration efficiency.

[0126] Specifically, the rate sum of the first spraying rate and the third spraying rate can be determined as the current spraying rate of the spraying unit.

[0128] As shown in Figure 8 The latent heat type air conditioner further includes a four-way valve 12, which is in communication with one end of the heat exchanger 52, the evaporator 20, the gas inlet of the compressor 10, and the gas outlet of the compressor 10.
