2 TECHNICAL AND DIMENSIONAL SPECIFICATIONS
2.1 Operating principle
The air-water heat pump uses the energy of the air existing in the environment. The air required for
the proper operation of the heat pump can be drawn from the outside through a window (minimum
temperature -20°C) or from the surrounding environment or from other environments through ducts.
The air drawn from the environment is sucked through a fan and the heat existing in air is absorbed
during the passage in a heat exchanger (evaporator). In the evaporator the heat taken from the air is
caused to evaporate at low pressure by the refrigerant (the working fluid in the refrigerant circuit,
is as in a household fridge). The vaporized coolant is sucked by a compressor and raised to a
higher level of pressure (as in a bicycle pump) and temperature. In a second heat exchanger
(condenser) the higher temperature heat is absorbed and transferred to the water; this way the
