Abstract

The invention relates to a cascade type refrigerant circulation system, air-conditioner equipment and a control method of the cascade type refrigerant circulation system. The cascade type refrigerantcirculation system comprises a first refrigerant system (1), a second heat exchanger (3) and a second refrigerant system (2), wherein the first refrigerant system (1) comprises a first compressor (11), an outdoor heat exchanger (14) and a first throttling component (13), the second heat exchanger (3) comprises a first heat exchange portion and a second heat exchange portion configured to achieve heat exchange with the first heat exchange portion, and the first heat exchange portion communicates with the first refrigerant system (1) to form a refrigerant circulation loop. The second refrigerantsystem (2) comprises a second compressor (21), a second heat exchanger (22) and a second throttling component (23). The second refrigerant system (2) alternatively communicates with the second heat exchange portion or the outdoor heat exchanger (14) to form a refrigerant circulation loop.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a cascade refrigerant circulation system, an air conditioner and a control method for the cascade refrigerant circulation system. Background technique [0002] With the continuous development of society, air conditioners and heat pump equipment are becoming more and more diverse in the market, and refrigeration technology is becoming more and more mature. Taking the cascade refrigerant circulation system as an example, it can meet the special needs of users, such as the field of refrigeration, ultra-low temperature projects, ultra-high water temperature projects, high-temperature drying, etc. [0003] The cascade refrigerant circulation system has the advantages of high condensation or low evaporation. The advantages of the cascade refrigerant circulation system are not introduced here. However, the current conventional cascade system still has many components and the ov...
