Technical Field

[0002] Currently, when indoor temperatures are too high, air conditioning can be used to lower the indoor temperature and improve user comfort. However, if the indoor humidity is high during the temperature reduction process, it will increase the energy consumption of the air conditioner.

[0003] To address this, some existing technologies have been optimized by using multiple adsorption heat exchangers with adsorbent surfaces. Dehumidification or humidification is achieved by alternately using one of these heat exchangers as an evaporator for refrigerant to adsorb moisture from the air, and another as a condenser for refrigerant to remove moisture from the adsorbent. This allows for the simultaneous treatment of both latent and sensible heat in the room, improving the air conditioner's energy efficiency ratio.

[0004] In the process of implementing the embodiments of this application, at least the following problems were found in the related technology:

[0005] The temperature of the heat exchanger affects both the latent heat and sensible heat of the room, making it difficult to regulate the relative humidity. Summary of the Invention

The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this application. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0035] Unless otherwise stated, the term "multiple" means two or more.

[0036] In this embodiment, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0037] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0038] Figure 1 This is a schematic diagram of the structure of a latent heat type air conditioner provided in an embodiment of this application.

[0039] The latent heat type air conditioner includes a compressor 01, an evaporator 02, and a condenser 03. The compressor 01 is connected to the condenser 03, the condenser 03 is connected to the evaporator 02, and the evaporator 02 is connected to the compressor 01. The compressor 01 provides high-temperature and high-pressure gaseous refrigerant to the condenser 03. The gaseous refrigerant condenses and liquefies in the condenser 03 and releases heat to form liquid refrigerant. The liquid refrigerant flows into the evaporator 02, where it evaporates and vaporizes and absorbs heat to form gaseous refrigerant. The gaseous refrigerant is then recovered by the compressor 01.

[0040] In addition, combined Figure 1As shown, the latent heat type air conditioner includes a latent heat treatment device 13, a heating device 04, and a cooling device 07. The heating device 04 pumps a first fluid to the latent heat treatment device 13 through a first pumping unit 10 to raise the temperature of the latent heat treatment device 13. The cooling device 07 pumps a second fluid to the latent heat treatment device 13 through a second pumping unit 12 to lower the temperature of the latent heat treatment device 13.

[0041] The aforementioned latent heat treatment device 13 may include zeolite, silica gel, activated carbon, or other organic polymer materials with hydrophilic or water-absorbing properties. The latent heat treatment device 13 can perform a moisture absorption process and a regeneration process. During the moisture absorption process, the latent heat treatment device 13 absorbs moisture from the air, causing the air moisture content to decrease and the moisture content in the latent heat treatment device 13 to increase. During the regeneration process, the latent heat treatment device 13 releases moisture into the air, causing the air moisture content to increase and the moisture content in the latent heat treatment device 13 to decrease. When the latent heat treatment device 13 is in a temperature decrease phase, it performs the moisture absorption process; when the latent heat treatment device 13 is in a temperature increase phase, it performs the regeneration process.

[0042] For example, the latent heat treatment device 13 includes a first circulating air path 15, a second circulating air path 16, and a fan 14. The inlet and outlet of the first circulating air path 15 are located indoors, and the inlet and outlet of the second circulating air path 16 are located outdoors. The fan 14 provides aerodynamics to the first circulating air path 15 and the second circulating air path 16. After the fan 14 is started, air is passed through the first circulating air path 15 or the second circulating air path 16.

[0043] During the moisture absorption process of the latent heat treatment device 13, the fan 14 is turned on, the first circulation air path 15 is opened, and the second circulation air path 16 is closed. Under the action of the fan 14, indoor air passes through the latent heat treatment device 13 and returns to the room. During the air circulation process, the latent heat treatment device 13 absorbs moisture from the air, reducing the moisture content in the air. During the dehumidification process of the latent heat treatment device 13, the fan 14 is turned on, the first circulation air path 15 is closed, and the second circulation air path 16 is opened. Under the action of the fan 14, outdoor air passes through the latent heat treatment device 13 and returns to the outside. The moisture in the latent heat treatment device 13 is carried outdoors by the outdoor air, preparing for the next moisture absorption process.

[0044] The heating device 04 may be provided with a first receiving cavity 05 to store a first fluid, which may be water or frozen brine, and the first pumping unit 10 may be a water pump; the cooling device 07 may be provided with a second receiving cavity 08 to store a second fluid, which may be water or frozen brine, and the second pumping unit 12 may be a water pump.

[0045] A first circulation pipeline 09 is provided between the heating device 04 and the latent heat treatment device 13. A first pumping unit 10 is installed on the first circulation pipeline 09 to provide power for the first fluid, so that the first fluid circulates between the heating device 04 and the latent heat treatment device 13.

[0046] A second circulation pipeline 11 is provided between the cooling device 07 and the latent heat treatment device 13. A second pumping unit 12 is installed on the second circulation pipeline 11 to provide power for the second fluid, so that the second fluid circulates between the heating device 04 and the latent heat treatment device 13.

[0047] Furthermore, a heat exchanger 06 is installed in the first receiving cavity 05 of the heating device 04. One end of the heat exchanger 06 is connected to the outlet of the compressor 01, and the other end is connected to the condenser 03.

[0048] During the refrigeration process, the heat generated by the condenser 03 is "waste heat". In this embodiment, the heat generated by the condenser 03 is applied to the regeneration process of the latent heat treatment device 13, which effectively utilizes the heat generated by the condenser 03 and improves the energy efficiency ratio of the air conditioner.

[0049] During the cooling process of the air conditioner, both the indoor temperature and the set temperature are obtained. The greater the temperature difference between the indoor temperature and the set temperature, the higher the operating frequency of the air conditioner compressor 01. Combined with the technical solution in this embodiment, the higher the operating frequency of the compressor 01, the higher the pressure of the refrigerant supplied by the compressor 01 to the heat exchanger 06, resulting in a higher temperature in the heat exchanger 06 and a higher temperature in the first fluid. Since the first fluid is used to heat the latent heat treatment device 13, the higher the temperature of the first fluid, the faster the heating rate of the latent heat treatment device 13 during the heating process. Simultaneously, the higher the temperature of the first fluid, the greater the maximum temperature change of the latent heat treatment device 13. During the cooling process, a larger temperature difference can be maintained between the latent heat treatment device 13 and the cooling device 07, thus increasing the cooling speed. This improves both the heating and cooling rates of the latent heat treatment device 13, increasing the rate at which the latent heat treatment device 13 processes latent heat. Even when cooling rooms with high humidity, a better latent heat treatment rate can be maintained, improving the energy efficiency ratio of the air conditioner.

[0050] Figure 2 This is a schematic diagram illustrating a control method for a latent heat type air conditioner provided in an embodiment of this application. The control method for the latent heat type air conditioner can be executed by the controller of the latent heat type air conditioner, or by a control panel communicatively connected to the air conditioner, or by a server in a smart home system. This embodiment of the application applies the control method for the latent heat type air conditioner to... Figure 1 The latent heat type air conditioner shown is illustrated by way of example.

[0051] Combination Figure 2 As shown, the control method for latent heat type air conditioning includes:

[0052] S201. Obtain the first indoor temperature and first relative humidity before the current moment, and obtain the second indoor temperature and second relative humidity at the current moment.

[0053] The temperature difference between the first temperature and the second temperature is within a preset temperature range, for example, the preset temperature range can be 2℃~3℃, 3℃~4℃, 4℃~5℃ or 5℃~6℃; the above temperature difference can be obtained by subtracting the second temperature from the first temperature.

[0054] Prior to the current moment, multiple times with the same temperature and relative humidity were recorded. Multiple temperatures and their corresponding relative humidity prior to the current moment can be obtained. The temperature that equals the sum of the second temperature and the preset temperature is defined as the first temperature, and the relative humidity corresponding to the temperature that equals the sum of the second temperature and the preset temperature is defined as the first relative humidity.

[0055] S202, Obtain the relative humidity difference between the second relative humidity and the first relative humidity.

[0056] S203. Based on the relative humidity difference, the second relative humidity, and the set relative humidity, adjust the first pumping rate of the first pumping unit and the second pumping rate of the second pumping unit.

[0057] During initial operation, both the first and second pumping rates are set to default values. During subsequent operations, the first and second pumping rates are adjusted based on the relative humidity difference, the second relative humidity, and the set relative humidity, adjusting the values ​​from the previous operation.

[0058] When the first pumping rate of the first pumping unit changes, the heating rate of the latent heat treatment device will change; when the second pumping rate of the second pumping unit changes, the cooling rate of the latent heat treatment device will change. This causes a change in the rate at which the latent heat is removed by the latent heat treatment device, which in turn causes a change in the relative humidity of the room as the temperature decreases.

[0059] When the first pumping unit is a water pump, the first pumping rate can be expressed by the water pump speed; when the second pumping unit is a water pump, the second pumping rate can be expressed by the water pump speed.

[0060] The first pumping rate and the second pumping rate can be adjusted as follows: when the first relative humidity is greater than or equal to the second relative humidity and the second relative humidity is less than the 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.

[0061] The relative humidity setting here can be user-defined, or it can be the most suitable relative humidity setting for the current weather or the current user, calculated based on existing big data algorithms or artificial intelligence algorithms.

[0062] Reducing the first and second pumping rates decreases the rate at which the latent heat treatment device removes latent heat from the room. As the indoor temperature decreases, the indoor relative humidity tends to increase. Reducing the rate of latent heat removal can reduce the counteracting effect on the increasing relative humidity, which is beneficial for the indoor relative humidity (second relative humidity) to approach the set relative humidity.

[0063] The first pumping rate and the second pumping rate can be adjusted as follows: when the first relative humidity is less than or equal to the second relative humidity and the second relative humidity is greater than the 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.

[0064] Increasing the first and second pumping rates improves the rate at which the latent heat treatment device removes latent heat from the room. As the indoor temperature decreases, the indoor relative humidity tends to increase. Increasing the rate of latent heat removal can enhance the counteracting effect on the increasing relative humidity, which is beneficial for the indoor relative humidity (second relative humidity) to approach the set relative humidity.

[0065] When the first relative humidity is greater than or equal to the second relative humidity, and the second relative humidity is greater than the set relative humidity, the first pumping rate and the second pumping rate can be kept constant, 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 decreased.

[0066] When the first relative humidity is less than or equal to the second relative humidity, and the second relative humidity is less than the set relative humidity, the first pumping rate and the second pumping rate can be kept constant, 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 decreased.

[0067] Optionally, reducing the first pumping rate based on the relative humidity difference and reducing the second pumping rate based on the relative humidity difference include: obtaining a first rate that is positively correlated with the absolute value of the relative humidity difference, thereby reducing the first pumping rate by the first rate; and obtaining a second rate that is positively correlated with the absolute value of the relative humidity difference, thereby reducing the second pumping rate by the second rate.

[0068] The correspondence between the absolute value of the relative humidity difference and the first pumping rate can be stored in a database first. Once the relative humidity difference is obtained, the first pumping rate corresponding to the absolute value of the relative humidity difference can be obtained. Similarly, the correspondence between the absolute value of the relative humidity difference and the second pumping rate can be stored in a database first. Once the relative humidity difference is obtained, the second pumping rate corresponding to the absolute value of the relative humidity difference can be obtained. The difference between two first pumping rates can be determined as the adjusted first pumping rate; the difference between two second pumping rates can be determined as the adjusted second pumping rate.

[0069] Optionally, increasing the first pumping rate based on the relative humidity difference and increasing the second pumping rate based on the relative humidity difference include: obtaining a third rate that is positively correlated with the absolute value of the relative humidity difference, thereby increasing the first pumping rate by the third rate; and obtaining a fourth rate that is positively correlated with the absolute value of the relative humidity difference, thereby increasing the second pumping rate by the fourth rate.

[0070] The correspondence between the absolute value of the relative humidity difference and the third rate can be stored in a database first. After obtaining the relative humidity difference, the third rate corresponding to the absolute value of the relative humidity difference can be obtained. Similarly, the correspondence between the absolute value of the relative humidity difference and the fourth rate can be stored in a database first. After obtaining the relative humidity difference, the fourth rate corresponding to the absolute value of the relative humidity difference can be 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.

[0071] Optionally, adjusting the first pumping rate of the first pumping unit and the second pumping rate of the second pumping unit based on the relative humidity difference, the second relative humidity, and the set relative humidity includes:

[0072] The system calculates the interval between the moment corresponding to the second temperature and the current moment. If the interval is less than or equal to a first set interval, it adjusts the first pumping rate of the first pumping unit and the second pumping rate of the second pumping unit based on the relative humidity difference, the second relative humidity, and the set relative humidity. An interval less than or equal to the first set interval indicates a significant drop in indoor temperature; in this case, the indoor relative humidity is adjusted according to the aforementioned technical solution. If the interval is greater than or equal to the first set interval, it indicates that the indoor temperature drop is not significant, and other existing technologies can be used for dehumidification alone.

[0073] S204. Control the first pumping unit and the second pumping unit to operate alternately according to the adjusted first pumping rate and the adjusted second pumping rate.

[0074] Optionally, controlling the first pumping unit and the second pumping unit to operate alternately according to the adjusted first pumping rate and the adjusted second pumping rate includes: alternately controlling the first pumping unit to operate at the adjusted first pumping rate for a second set duration, and controlling the second pumping unit to operate at the adjusted second pumping rate for a second set duration.

[0075] Alternatively, controlling the alternating operation of the first pumping unit and the second pumping unit according to the adjusted first pumping rate and the adjusted second pumping rate may include: obtaining the weight or conductivity of the hygroscopic material in the latent heat treatment device; if the weight or conductivity of the hygroscopic material is greater than or equal to a first set value, shutting down the second pumping unit and starting the first pumping unit to switch the latent heat treatment device from the hygroscopic process to the regeneration process; if the weight or conductivity of the hygroscopic material is less than or equal to a second set value, starting the second pumping unit and shutting down the first pumping unit to switch the latent heat treatment device from the regeneration process to the hygroscopic process.

[0076] During the process of lowering the indoor temperature, the indoor relative humidity will change in different ways as the indoor temperature and the absolute humidity of the indoor air decrease. The relative humidity difference between the first and second relative humidity can reflect the change in indoor relative humidity. Combined with the set relative humidity, the rate of latent heat removal can be adjusted adaptively, thereby adjusting the current indoor relative humidity to make it easier to reach the set relative humidity.

[0078] Combination Figure 3 As shown, the control method for latent heat type air conditioning includes:

[0079] S301, Obtain the current indoor temperature and relative humidity.

[0080] S302. Determine the target temperature range based on the sum of the second temperature and the upper limit temperature of the preset temperature range, and the sum of the second temperature and the lower limit temperature of the preset temperature range.

[0081] For example, the sum of the second temperature and the upper limit temperature of the preset temperature range is determined as the upper limit temperature of the target temperature range; the sum of the second temperature and the lower limit temperature of the preset temperature range is determined as the lower limit temperature of the target temperature range.

[0082] The preset temperature range here can be 2℃~3℃, 3℃~4℃, 4℃~5℃, or 5℃~6℃.

[0083] S303: Obtain multiple historical temperatures up to the current moment.

[0084] It can periodically detect and record multiple historical temperatures up to the current moment.

[0085] S304. Determine the first temperature within the target temperature range from multiple historical temperatures.

[0086] If there is only one historical temperature within the target temperature range, then that historical temperature is determined as the first temperature; if there are multiple historical temperatures within the target temperature range, then the most recently obtained historical temperature is determined as the first temperature.

[0087] S305. Obtain the relative humidity difference between the second relative humidity and the first relative humidity.
