Abstract

The invention provides a hot water system of a heat pump, which comprises a refrigerant loop pipeline formed by the serial connection of a compressor, a first heat exchanger, an expansion unit and a heat exchange module, and a liquid-cycle-cooling pipeline connected with a valve, the heat exchange module and the first heat exchanger. The heat exchange module comprises a second heat exchanger and an efficiency enhancer. Liquid flows from the input pipe of the liquid-cycle-cooling pipeline to the efficiency enhancer of the heat exchange module after flowing through the valve, and then flows out of the output pipe of the liquid-cycle-cooling pipeline after flowing through the first heat exchanger. When the liquid flows through the heat exchange module, heat exchange is carried out between the liquid and a refrigerant in the efficiency enhancer. Therefore, the temperature of the refrigerant is increased before the refrigerant flows into the compressor. When the liquid flows through the first heat exchanger, heat exchange is carried out between the liquid and a refrigerant in the first heat exchanger. Therefore, the temperature of the liquid flowing out of the output pipe of the liquid-cycle-cooling pipeline is increased.

Description

technical field [0001] The invention relates to a heat pump water heating system, in particular to a heat pump water heating system capable of improving heating efficiency. Background technique [0002] The heat pump hot water system is designed according to the reverse-Rankine cycle (Rankine cycle), using the compressor to compress the gaseous refrigerant into a high-temperature and high-pressure superheated refrigerant to heat the liquid, and expand it through the constant enthalpy of the expansion valve to become a low-temperature and low-pressure refrigerant. Refrigerant, and then through a fin-tube heat exchanger (such as an evaporator) to obtain heat from the outside of the heating equipment. [0003] like figure 1 As shown, it schematically shows the basic components of a traditional heat pump water heating system. The heat pump water heating system mainly includes an evaporator 11 , a compressor 12 , a condenser 13 , an expansion valve 14 and a water storage tank 15...
