SYSTEM DIAGRAM
F370 consists of a heat pump, water heater, immersion
heater, fan, circulation pump and control system.F370 is
connected to the ventilation system and heating medium
circuits.
When the exhaust air at room temperature passes through
the evaporator, the refrigerant evaporates because of its
low boiling point. As a result, the air releases energy to the
refrigerant.
The refrigerant is then compressed in a compressor, causing
the temperature to rise considerably.
The warm refrigerant is led to the condenser. Here the refri-
gerant gives off its energy to the heating system 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 re-
turns to the evaporator.
