1.
The coolant R134a is compressed in a highly efficient compressor that increases its pressure
and temperature.
2.
In a capacitor that is not in direct contact with water, the thermal energy contained in the coolant
is transferred to the water in the hot water storage tank.
3.
Condensed liquid flows from the expansion valve that is responsible for a drop in its pressure.
4.
The fluid absorbs thermal energy from the air flowing through the evaporator with the help of a fan.
R134a is a HFC coolant, and therefore does not damage the ozone layer. It is characterized
by excellent chemical and thermal stability, low toxicity, is not flammable and is compatible
with most materials.
