HPAC 42 is a cooling module that should be included
in a system where the main components are the heat
pump FIGHTER 1330 and exchanger module HPAC
42. FIGHTER 1330 has an integrated control system
to regulate the heating/cooling, integrated circulation
pumps and is connected via the HPAC module to the
external collector and the building's distribution system
for heating and cooling.

The heat exchange from the heat source (rock, ground
or lake) takes place via a closed cooling medium sys-
tem where water mixed with antifreeze circulates to
the heat pump.
Ground water can also be used as a heat source how-
ever, this requires an intermediate heat exchanger
between the HPAC and the ground water.
