An underground probe for a heat pump system evaporator has an outer tube and an inner tube into which the coolant is released for recirculation through a heat exchanger

摘要

The heat pump system has a compressor (9) and evaporator heat exchanger (6) in which a liquid is circulated through a tube (17) into the inner tube (14) returning to the heat exchanger through the primary tube (3). Cooling water (13) enters at an inlet (23) and (23.3) into a tube (23.2) to exit at the outlet (23.1).
