SYSTEM DIAGRAM
S135 is an exhaust air module.
When the air passes through the evaporator, the refri-
gerant evaporates because of its low boiling point. In
this way the energy in the air is transferred to the refri-
gerant.
The refrigerant is then compressed in a compressor,
causing the temperature to rise considerably.
The warm refrigerant is led to the condenser. Here, the
refrigerant gives off its energy to the hot water,
whereupon the refrigerant changes state from gas to
liquid.
The refrigerant then goes via filters to the expansion
valve, where the pressure and temperature are reduced.
The refrigerant has now completed its circulation and
returns to the evaporator.
