Description and operation
3.2.1
Self-Contained Air Conditioning Unit
ATTENTION
All Webasto air conditioning units pump seawater around the condenser to aid in the cooling process.
Cooling Cycle
The compressor compresses the refrigerant gas which is then condensed to liquid as it passes through
the seawater cooled condenser. The liquid refrigerant is injected through a small nozzle and
evaporates. This evaporation process produces the refrigeration effect. The evaporation takes place in
a tubular finned coil (also called: evaporator coil). A blower forces the air through the evaporator coil.
While passing through the evaporator the temperature of the air is lowered by approximately 15 °C
(59 °F).
Heating Cycle (option)
ATTENTION
The heat cycle becomes inefficient when the outside water temperature drops below 6 °C (43 °F) approx.
It is quite possible to produce heat with an air conditioning unit. For this purpose the unit shall be
equipped with a 4-way reversed cycle valve (option). During the heat cycle the condenser effectively
becomes the evaporator. It removes any available heat from the seawater and transfers it to the
refrigerant. The finned evaporator becomes the condenser and produces heat to approx. 45/50 °C
(113/122 °F).
