[0079] Air conditioning units execute a refrigeration cycle using a compressor, condenser, throttling device, and evaporator. The refrigeration cycle involves a series of processes, including compression, condensation, expansion, and evaporation, to cool or heat an indoor space.

[0080] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0081] The throttling device expands the high-temperature, high-pressure liquid refrigerant that condenses in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the throttling device, returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0082] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and a throttling device can be provided in either the indoor or outdoor unit.

[0083] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0090] The circulation device 23 is configured to generate circulation power and is located on the circulation pipeline between the energy storage device 21 and the indoor auxiliary heat exchanger 22.

[0091] In some embodiments, the circulation device 23 is a circulation pump.

[0092] The fan 16 is configured to generate airflow through the indoor auxiliary heat exchanger 22.

[0093] The air conditioning unit includes a refrigerant circulation system, an energy storage device 21, an indoor auxiliary heat exchanger 22, circulation pipes, a circulation device 23, and a fan 16. The refrigerant circulation system includes a compressor 11, a four-way valve 12, an outdoor heat exchanger 13, a first throttling device 14, and an indoor heat exchanger 15. The energy storage device 21 receives and stores the energy generated by the outdoor heat exchanger 13. The indoor auxiliary heat exchanger 22 is configured to exchange energy with indoor air and is connected to the energy storage device 21 through the circulation pipes. The circulation device 23 is installed on the circulation pipes. The fan 16 generates airflow that flows through the indoor auxiliary heat exchanger 22. Therefore, during bathing, the air conditioning unit can regulate the indoor temperature through the indoor heat exchanger 15 to ensure the comfort of the indoor temperature, and at the same time receive and store the energy generated by the outdoor heat exchanger 13 through the energy storage device 21; after bathing, the energy of the energy storage device 21 is circulated to the indoor auxiliary heat exchanger 22 through the circulation device 23, and the indoor humidity is regulated through the indoor auxiliary heat exchanger 22 to ensure the comfort of the indoor humidity after bathing.

[0094] In some embodiments, during bathing, the air conditioning unit enters heating mode: the four-way valve 12 is in the heating conduction state, the compressor 11 compresses to form a high-temperature refrigerant, which passes through the four-way valve 12 and enters the indoor heat exchanger 15. The indoor heat exchanger 15 heats the air, and the fan 16 runs, so the indoor air passes through the indoor heat exchanger 15, which heats the air in the bathroom to regulate the indoor temperature. Then the refrigerant is throttled by the first throttling device 14, evaporates and absorbs heat in the outdoor heat exchanger 13, which cools the air. Afterward, it returns to the compressor 11 after passing through the four-way valve 12.

[0095] The energy storage device 21 receives and stores the cooling energy generated by the outdoor heat exchanger 13.

[0096] After showering, the air conditioning unit enters dehumidification mode. The circulation device 23 circulates the cold energy stored in the energy storage device 21 to the indoor auxiliary heat exchanger 22. The fan 16 runs, and the hot and humid air in the bathroom condenses into water droplets when it encounters the cold indoor auxiliary heat exchanger 22, thus achieving the indoor dehumidification function and regulating the indoor humidity.

[0105] In some embodiments, heat pipe 24 is in contact with outdoor heat exchanger 13.

[0106] When the outdoor heat exchanger 13 is cooling, the cooling capacity of the outdoor heat exchanger 13 reaches the condensing section of the heat pipe 24 to cool the condensing section of the heat pipe 24. The gaseous medium in the condensing section of the heat pipe 24 will condense and release heat to become liquid. The liquid medium flows back to the evaporating section of the heat pipe 24 under the action of the capillary tube, absorbs the heat in the energy storage device 21 and vaporizes into gas. The gaseous medium returns to the condensing section of the heat pipe 24, realizing a cycle, continuously dissipating the heat of the energy storage device 21, and then the energy storage device 21 stores the cooling capacity.

[0107] exist Figure 2 In one embodiment, the air conditioning unit includes an energy storage circulation pipeline and an energy storage circulation device 25.

[0136] exist Figure 12 In one example, the indoor unit of the air conditioning unit was installed on the ceiling of the bathroom.

[0137] Therefore, air conditioning units can achieve heating mode, cooling mode, cold storage and dehumidification mode, and turbid heat recovery mode.

[0138] (1) Heating mode.

[0139] When the four-way valve 12 is in the heating state, the compressor 11 compresses the refrigerant to form a high-temperature refrigerant, which enters the indoor heat exchanger 15 through the four-way valve 12. The indoor heat exchanger 15 heats the air, and the fan 16 runs to generate circulating airflow, heating the air in the bathroom. Then, the refrigerant is throttled by the first throttling device 14 and evaporates and absorbs heat in the outdoor heat exchanger 13. The outdoor heat exchanger 13 cools the air, and the outdoor fan 131 runs, allowing the refrigerant to return to the compressor 11 through the four-way valve 12.

[0141] (2) Cooling mode.

[0142] When the four-way valve 12 is in the cooling-conducting state, the compressor 11 compresses the refrigerant to form a high-temperature refrigerant, which then enters the outdoor heat exchanger 13 through the four-way valve 12. The outdoor heat exchanger 13 provides heating, and the outdoor fan 131 operates. Then, the refrigerant is throttled by the first throttling device 14 and evaporates in the indoor heat exchanger 15, absorbing heat. The indoor heat exchanger 15 provides cooling, and the fan 16 operates to generate circulating airflow, cooling the indoor air. The refrigerant then returns to the compressor 11 through the four-way valve 12.

[0143] (3) Cold storage and dehumidification mode.

[0144] When the four-way valve 12 is in the heating state, the compressor 11 compresses the refrigerant to form a high-temperature refrigerant, which then enters the indoor heat exchanger 15 through the four-way valve 12. The indoor heat exchanger 15 heats the air, and the fan 16 runs to generate circulating airflow, heating the air in the bathroom. Then, the refrigerant is throttled by the first throttling device 14 and evaporates and absorbs heat in the outdoor heat exchanger 13. The outdoor heat exchanger 13 cools the air, and the outdoor fan 131 runs, returning the refrigerant to the compressor 11 through the four-way valve 12. The energy storage device 21 receives and stores the cooling energy generated by the outdoor heat exchanger 13.

[0145] When the circulation device 23 is started, the circulating medium absorbs the cold energy in the energy storage device 21 and transfers it to the indoor auxiliary heat exchanger 22. The fan 16 generates a circulating airflow that passes through the indoor auxiliary heat exchanger 22. When the hot and humid air in the bathroom encounters the cold indoor auxiliary heat exchanger 22, it condenses into water droplets, thus achieving the dehumidification function.

[0146] (4) Turbidity heat recovery mode.

[0147] When the exhaust fan 3 is turned on, the hot and humid air in the bathroom is exhausted, ensuring that the air in the bathroom is fresh during showering. The exhausted hot and humid air is delivered to the outdoor heat exchanger 13 of the outdoor unit through the exhaust duct 31, which increases the temperature of the outdoor heat exchanger 13 (in some embodiments, the air conditioner is in heating mode and the outdoor heat exchanger is in cooling mode during showering, so the hot and humid air exhausted from the exhaust duct 31 can increase the temperature of the outdoor heat exchanger 13), thereby improving the efficiency of the entire system and realizing energy recovery.

[0155] Water tank 61 is connected to heat exchanger 51 via a circulation pipeline, and water pump 62 is located on the circulation pipeline. When water pump 62 is running, the medium circulates between water tank 61 and heat exchanger 51 to transfer heat from heat exchanger 51 to water tank 61, thereby increasing the water temperature in water tank 61.

[0156] In some embodiments, the air conditioning unit further includes a switching device.

[0157] Heat exchanger 51 and indoor heat exchanger 15 are connected to the refrigerant circulation system via a switching device.

The outdoor heat exchanger 13 cools the air, and the outdoor fan 131 runs. The refrigerant returns to the compressor 11 through the four-way valve 12.

The water pump 62 starts to transfer the heat from the heat exchanger 51 to the water tank 61, raising the water temperature in the tank and producing hot water. Then, the refrigerant in the indoor heat exchanger 15 is throttled by the first throttling device 14, and the refrigerant in the heat exchanger 51 is throttled by the second throttling device 52, entering the outdoor heat exchanger 13 to evaporate and absorb heat. The outdoor heat exchanger 13 cools the air, and the outdoor fan 131 runs, returning the refrigerant to the compressor 11 through the four-way valve 12.

The outdoor heat exchanger 13 cools the air, and the outdoor fan 131 runs, returning the refrigerant to the compressor 11 through the four-way valve 12.
