Summary

Experiments are carried out on a R114 dehumidifying heat pump installed in a closed circuit drying tunnel. The influence of auxiliary heat input before condenser and/or evaporator are studied. Actual coefficient of performance varied from about 2 to 3. Studies throw light on the significance of the location of the auxiliary heat input in the drying circuit. It is observed that the dryer temperature could be controlled within certain limits using the low grade heat input before the condenser or evaporator. This could substitute high temperature heat conventionally input after the condenser. This is also significant if the same dryer has to be used for drying different materials which require different drying temperatures.
