Patent number: 11927366Abstract: The present invention provides a cold-storage instantaneous heat pump water heater (HPWH). The HPWH includes a cold-water tank, a main evaporator, a compressor, and a hot water heat exchanger. In the present invention, heat of a working medium in the cold-water tank is absorbed by the main evaporator, and bathing water is rapidly heated by the hot water heat exchanger (condenser of the heat pump), thereby realizing instant heating with small input electrical power. Cold-water tank replaces the hot water tank of conventional HPWH avoiding energy loss during hot water storage. The working medium in the cold-water tank absorbs heat from the environment, to further improve energy utilization. In addition, there are three energy recovery evaporators to recover the waste heat of bathing.Type: GrantFiled: March 3, 2020Date of Patent: March 12, 2024Assignee: BEIJING UNIVERSITY OF CIVIL ENGINEERING AND ARCHITECTUREInventors: Rongji Xu, Yinshi Li
