A central split system geothermal heat pump
is a common style of ground-source HVAC
installation. Like a conventional split system, a geothermal split consists of multiple components integrated into a single system via refrigerant
lines and communicating cables. This setup typically includes an air handler
with an interior fan and an outdoor cabinet that houses the compressor
. Depending on the particular needs at hand, an extra coil might be included to accommodate duel fuel applications or a desuperheater to make use of excess hot water.
