The invention discloses a refrigerant circulation system and a refrigerant circulation method thereof. The circulation system comprises: a compressor, a first heat exchanger, a gas-liquid separator, a second heat exchanger, and a plate heat exchanger; The heat exchanger includes a first channel and a second channel that are independent of each other; the inlet and outlet of the first channel are respectively connected with the outlet of the compressor and the inlet of the gas-liquid separator through pipes, and the inlet and outlet of the second channel are respectively connected with the gas through pipes. The gas outlet of the liquid separator is connected with the inlet of the hot side of the plate heat exchanger; through the improvement of the first heat exchanger, the first heat exchanger is improved from a traditional single-channel structure to a double-channel structure, and the improved The combination of the first heat exchanger and the plate heat exchanger not only realizes the secondary liquefaction of the refrigerant, but also increases the amount of the refrigerant involved in the circulation in the refrigerant circulation system, increases the released heat, and then improves the heating capacity. While reducing energy consumption, it saves costs for users.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a refrigerant circulation system and a refrigerant circulation method thereof. Background technique [0002] Usually, when the air conditioner is heating in winter, the refrigerant passing through the compressor first enters the indoor condenser to liquefy the gas and release heat; then the refrigerant enters the outdoor evaporator through the expansion valve to realize liquid vaporization and absorb outdoor heat. ; After that, the refrigerant enters the compressor again for compression, and then enters the indoor condenser again for liquefaction and release of heat; through the continuous circulation of the refrigerant, the heating of the air conditioner is realized. [0003] However, in winter, the outdoor temperature is low, which makes the refrigerant circulation insufficient, resulting in insufficient heating capacity of the air-conditioning unit. It is necessary to...
