SYSTEM DIAGRAM
F110 consists of a heat pump, water heater, immersion
heater and control system.
When the air passes through the evaporator, the refrigerant
evaporates because of its low boiling point. In this way the
energy in the air is transferred 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 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 re-
turns to the evaporator.
