The Evaporator

Aided by an electrical fan, the evaporator absorbs latent heat by forcing air across the evaporator coils from the surrounding air which removes the heat from the refrigerant and produces cold air which causes a change in the state of the refrigerant back into a vapour.

Partial Loss of refrigerant can result in lower evaporation pressures and possibly uneven frosting of the evaporator (if below degrees celsius.

It is important to maintain the system evaporating pressures as high as possible to reduce energy consumption, which also helps to reduce indirect global warming.

For every 1K increase in evaporating temperature the cooling effect capacity increases by 3% and the corresponding energy use decreases by 3%

The basic function of the condenser is to:

• Absorb latent heat from the space being cooled.
• Change the state of the refrigerant from a liquid state to a vapour state.
