The heat pump dryer recovers heat from the drying exhaust vapour that is lost in open conventional dryers. A properly designed heat pump dryer has a closed loop and fully recovers energy that is distributed for both the heating and cooling required in a drying process. The refrigerant flows through the evaporator where it absorbs latent heat from the exhaust vapour and recycles it through the condenser (Lock 1996).
