Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, such as a multi-way valve body assembly and an air conditioning system. Background Technology

[0002] Air conditioning systems typically have cooling and heating modes. Through the circulation of refrigerant in a loop formed by the compressor, four-way valve, outdoor heat exchanger, throttling device, dehumidifying heat exchanger, and compressor, indoor temperature and humidity can be improved, enhancing user comfort. The dehumidifying function of an air conditioner is usually based on the principle of water vapor condensation. When humid air passes through a heat exchanger with a lower surface temperature, the air temperature drops significantly, causing the air humidity to reach a supersaturated state. Excess water vapor then condenses out as water, thus reducing the air humidity.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] Currently, four-way valves are commonly used in air conditioning systems to regulate the refrigerant flow in the refrigerant circulation loop, enabling the system to operate in heating, cooling, or dehumidification mode. However, existing four-way valves have a relatively complex structure.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0116] The first control unit is configured to control the first throttling element 81 and the second throttling element 82 to be fully open without throttling, control the opening of the dehumidification valve 83 to throttle, and control the indoor exhaust fan 94 to be shut off. The high-pressure refrigerant compressed by the compressor 4 flows through the system four-way valve 5 to the first port 101 of the multi-way valve assembly, and then through the second port 102 of the multi-way valve assembly into the reheat heat exchanger 72 for condensation and heat release, heating the air.

The high-pressure refrigerant compressed by the compressor 4 flows to the outdoor heat exchanger 6 via the system four-way valve 5, then flows through the heat recovery heat exchange assembly 71 into the fourth port 104 of the multi-way valve body assembly, and from the second port 102 of the multi-way valve body assembly into the reheat heat exchanger 72 for condensation and heat release, heating the air.

The high-pressure refrigerant compressed by the compressor 4 flows to the outdoor heat exchanger 6 through the system four-way valve 5 for condensation and heat release. After passing through the heat recovery heat exchange assembly 71, it recovers the indoor cooling capacity. Then, after being throttled by the second throttling element 82, it flows into the fourth port 104 of the multi-way valve body assembly. From the second port 102 of the multi-way valve body assembly, it flows into the reheat heat exchanger 72 and the dehumidification heat exchanger 73 for evaporation and heat absorption. After that, it flows into the third port 103 of the multi-way valve body assembly, and then flows back to the compressor 4 through the first port 101 of the multi-way valve body assembly and the system four-way valve 5.

[0125] The air conditioning system provided in this embodiment can achieve a heating mode.

[0126] The air conditioning system includes a fourth control unit, which can control the heating mode of the air conditioning system.

[0127] The fourth control unit is configured to control the dehumidification valve 83 to be fully open without throttling. The high-pressure refrigerant compressed by the compressor 4 flows through the system four-way valve 5 to the first port 101 of the multi-way valve body assembly, and then through the second port 102 of the multi-way valve body assembly into the reheat heat exchanger 72 and the dehumidification heat exchanger 73 for condensation and heat release, heating the air. After that, it flows into the third port 103 of the multi-way valve body assembly, and from the fourth port 104 of the multi-way valve body assembly, after being throttled by the second throttling element 82, it flows into the heat recovery heat exchange assembly 71 for evaporation and heat absorption, absorbing indoor heat. After being throttled again by the first throttling element 81, it flows into the outdoor heat exchanger 6, and then flows back to the compressor 4 through the system four-way valve 5.

[0128] As can be seen, the air conditioning system provided in this embodiment, whether operating in heating and dehumidification, constant temperature dehumidification, or cooling or heating mode, the refrigerant flows from the reheat heat exchanger 72 to the dehumidification heat exchanger 73 in the indoor dehumidification heat exchange component, which improves the operational stability of the air conditioning system and reduces the risk of refrigerant leakage.
