AWA-SS series consists of a heat pump, water heater,
electrical module, circulation pumps and a control sys-
tem. AWA-SS series is connected to the Outdoor Unit
and heating medium circuits.
The heat source of the AWA-SS series is provided from
air. the Outdoor Unit of the system is a heat exchanger
for collecting the heat of air.
The air emits its heat to the refrigerant in the evapo-
rate of Outdoorunit. It then vaporises and is com-
pressed in the compressor. The refrigerant, the tem-
perature of which has now been raised, is passed to
the condenser where it gives off its energy to the heat-
ing medium circuit and, if necessary, to the water
heater. After the condenser there is a built-in electrical
module which cuts in if there is a high demand.
