Abstract

The purpose of this research was to study on performance of a heat pump dryer using R32 refrigerant by recovering waste heat from an external condenser. Drying was carried out with drying temperatures of 45, 50 and 55 °C and water flow rates in the heat exchanger of 2, 3 and 4 L/min. Criteria for evaluating performance of heat pump dryer include: drying rate (DR), specific moisture extraction rate, specific energy consumption (SEC) and coefficient of performance of heat pump (COPh). The result shown that the performance of a heat pump dryer with heat recovery is higher than that of a traditional heat pump dryer. It was also found that increasing in drying temperature and water flow rate in heat exchanger resulted in an increase in the drying rate, power of the heat pump dryer and the specific moisture extraction rate. Whereas the specific energy consumption had decreased.
