2 TECHNICAL AND DIMENSIONAL SPECIFICATIONS
2.1 Operating principle
The all in one air to 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) / 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 the 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, as in a household fridge). The vaporized
refrigerant is drawn through a compressor and raised to a higher level of pressure and
temperature. In a second heat exchanger (condenser) the higher temperature heat is absorbed
and transferred to the water; this way the vaporized refrigerant fluid condenses back to the liquid
state as a consequence of thermal dissipation. The liquid refrigerant, flowing through a choking
component (expansion valve), undergoes a low-pressure expansion (dilatation) and, after
returning to the evaporator, it can again draw heat from the surrounding environment.
The hot water heat pump operates at ambient temperatures ranging between -20°C and
+43°C.
The hot water heat pump is a connection-ready equipment whose function is heating drinkable
water; it basically consists of the water tank and of the refrigerant, air and water circuit
components, as well as of all the control, adjustment and monitoring devices required for
automatic operation.
> Use of the environment energy
Refrigerators, washing machines, heating systems and other equipment/electric appliances
generate heat that in most cases is not reused. Instead of being dispersed into the environment,
generating pollution, the hot air in question can suitably be used to heat sanitary water: a
sensible and environment-friendly solution.
An important benefit is the air dehumidification resulting from heat suction, decreasing the
degree of humidity in cellars and laundries.
This has two beneficial effects: environment protection and production of cheap hot sanitary
water.
