Title:
HEAT PUMP UNIT
Document Type and Number:
WIPO Patent Application WO/2019/214425
Kind Code:
A1
Abstract:
Disclosed is a heat pump unit, comprising a liquid storage device (11) and a gas-liquid separation device (12), wherein the liquid storage device (11) is at least partially accommodated in the gas-liquid separation device (12), and a liquid heat transfer medium of high temperature and high pressure that is stored in the liquid storage device (11) can exchange heat with a gaseous heat transfer medium of low temperature and low pressure that is stored in the gas-liquid separation device (12) through a first housing (111). The heat transfer medium in the liquid storage device (11) obtains more frigories to improve the supercooling degree of the liquid heat transfer medium, and the heat transfer medium in the gas-liquid separation device (12) obtains more calories to improve the superheating degree of the gaseous heat transfer medium, such that the heat transfer efficiency of the heat pump unit is effectively improved.
