Document Type and Number:
WIPO Patent Application WO/2021/258689
Kind Code:
A1
Abstract:
The present application provides a heat exchange system, an air conditioning apparatus, and a control method for an air conditioning apparatus. The heat exchange system comprises: a compressor; a four-way valve; a first heat exchanger; a throttling device; a second heat exchanger; a liquid storage device comprising a first communication port and a second communication port, the first communication port being communicated with an air suction port, and the second communication port being communicated with one end of the second heat exchanger; a first valve body disposed on a flow path between the liquid storage device and the compressor; a second valve body disposed on a flow path between the second communication port of the liquid storage device and the throttling device; and a measurement device for measuring the amount of a refrigerant for heat exchange circulation in the heat exchange system, wherein when the heat exchange system operates in a heating work condition, working states of the first valve body and the second valve body are controlled according to the amount of the refrigerant of the heat exchange system. According to the heat exchange system provided in the present application, the amount of the refrigerant for heat exchange circulation in the heat exchange system can be increased or reduced according to actual situations, so as to reduce the power of the heat exchange system and improve the energy efficiency of the heat exchange system.
