A
heat pump works by transferring heat not by converting
electrical energy into heat. It removes energy from a low
temperature source (ambient air) and moves it to a high
temperature hot water tank.
1.Liquid (refrigerant) boils at a low temperature in an
evaporator.
output is low temperature and low pressure vapour.
2. Pressure and temperature of vapour increased in the
compressor.
electric motor used to drive vapour compressor.
output is high temperature and pressure vapour.
3. Heat exchanger in water tank.
output is heat transferred to water.
on refrigerant side output is warm liquid refrigerant.
4.Liquid is returned to the evaporator after passing through a
partially
open valve (tx valve or capillary tube).
output is low pressure cold liquid ready to be evaporated again.
