ABSTRACT:
A high coefficient of performance heat pump which extracts heat from or inputs heat into a liquid comprises a refrigerant compressor, a refrigerant, a plurality of refrigerant-fluid heat exchangers, two refrigerant expanders, two refrigerant check valves, a three way valve, refrigerant conduits, and liquid conduits connected in fluid tight communication. The apparatus can be employed to extract heat from or input heat into the earth, while heating or cooling air and/or water. An improved evaporator, refrigerant-liquid heat exchanger, component hook-up, and valve design are preferred embodiments.
