Problems solved by technology
However, in the heat pump system using a common compressor in the related art, as the temperature of the heat source decreases, the evaporation temperature and pressure of the system decrease, and the suction density of the compressor decreases, resulting in a decrease in the circulation flow of the refrigerant in the system, which in turn causes a decline in heating capacity and energy efficiency.
However, the heat pump system using frequency conversion compressor has complex control and high cost.

Description
technical field [0001] The invention relates to the technical field of electric appliance manufacturing, in particular to a heat pump system and an air conditioner with the heat pump system. Background technique [0002] As people's requirements for energy saving and environmental protection are getting higher and higher, heat pumps are gradually replacing traditional heating and hot water methods due to their high energy efficiency and environmental protection characteristics. However, in the heat pump system using ordinary compressors in the related art, as the temperature of the heat source decreases, the evaporation temperature and pressure of the system decrease, and the suction density of the compressor decreases, resulting in a decrease in the circulation flow of the refrigerant in the system, which in turn causes a decline in heating capacity and energy efficiency. . However, the heat pump system using the frequency conversion compressor has complicated control and ...
