Abstract
Description
Technical field
[0001] The invention relates to a heat pump system, in particular to a high-efficiency natural energy heat pump, which belongs to the technical field of heat pump applications. Background technique
[0002] Heat pumps have obvious energy-saving advantages because their heating energy efficiency ratio is always greater than 1, and they have been vigorously promoted and applied in modern society where energy is scarce. After the refrigerant enters the condenser, it releases heating heat and condenses into a medium-temperature and medium-pressure liquid refrigerant, which is then decompressed into a low-temperature and low-pressure refrigerant through the throttling device, then flows into the evaporator to absorb heat energy, and finally returns to the compressor to complete the cycle . When the ambient temperature of the condenser is low, it is easy to cause insufficient refrigerant quantity of the system evaporator, too low return air pressure, too little re...
