Principle of operation
Ambient air is drawn in by the fan and passed over the evaporator. The
evaporator cools the air, i.e. it extracts the heat it contains. In the evaporator,
the heat removed is transferred to the working fluid (refrigerant).
With the aid of an electrically driven compressor, the absorbed heat is
"pumped" to a higher temperature level through an increase in pressure and
given off to the heating water via the condenser (heat exchanger).
In so doing, the electrical energy is used to raise the heat of the environment
to a higher temperature level.
Due to the fact that the heat energy extracted from the air is transferred to the
heating water, this type of appliance is referred to as an air to water heat
pump.
The air to water heat pump consists of the following main components:
Evaporator, fan, expansion valve, low-noise scroll compressor, condenser
and the control unit.
In the case of low ambient temperatures, air humidity may accumulate on the
evaporator in the form of frost, impairing the heat transfer. The evaporator is
automatically defrosted by the heat pump, as required, with the possibility of
vapor plumes forming at the air outlet.

Compared with oil boiler, gas boiler and electrical heater, heat pump is
the best solution with high efficiency, safety and environment protect.
This high temperature air source heat pump use advanced heating
technology and intelligent control system. So it can work with the floor
heating pipe, the fan coil or the radiator, and replace the boiler directly.
In addition, the inverter heat pump can be used to provide hot water for
sanitary use, like kitchen, shower, etc.
