How Heat Pumps Work
A ‘‘Heat Pump’’ is a mover of heat, utilizing the available renewable heat from
the outside air. It works on the same principle as a refrigerator, but in reverse!
STAGE ONE
The vapor then passes to the compressor and is compressed. When compressed
the pressure is increased and the temperature of the vapour rises, effectively
concentrating the heat.
The hot vapor passes to the second heat exchanger (the condenser) where
the heat is rejected and the vapor condenses back into a liquid. In the case
of Altherma the rejected heat is passed into the water of the central heating
and hot water system ready for use in the home.
The liquid refrigerant than passes through an expansion valve, reducing
its pressure and temperature, ready to start the whole cycle once again.
The heat transfer medium (the refrigerant) is colder than the heat source
(the outside air). As the outside air passes across the first heat exchanger
(the evaporator) the liquid refrigerant absorbs the heat and evaporates.
