Abstract

ABSTRACT A sub-surface direct expansion geothermal heat exchange unit, which can be placed in sub-surface ground and/or water, consisting of at least one smaller interior diameter refrigerant liquid/fluid transport line (1) with an optional vertically oriented U bend (2) at the bottom, operatively connected to at least one larger interior diameter refrigerant liquid/fluid transport line (4), with at least one refrigerant flow metering device (5), designed to the system's compressor's BTU design capacity, which is optionally accessible, installed in the liquid/fluid line at one of an above-surface location and at the sub-surface point near to where the liquid/fluid line connects with the vapor/fluid line, for use when the system is operating in the heating mode, together with a refrigerant flow metering device by-pass means so as to enable additional refrigerant fluid flow at least one of around and past the refrigerant metering device when the system is operating in the cooling mode.
