Experimental optimization of an air source heat pump for drying fruits was conducted by varying the refrigerant charge; condenser fan speed and the ambient conditions to obtain the optimum operating parameters of the heat pump and the dryer as a single integrated unit. The results showed that; the coefficient of performance (COP) of the overall system and the cycle increased with the increase of condenser fan speed; ambient temperature and refrigerant charge. However; at high refrigerant charge and speed of the condenser fan; the COP of the overall system decreased because of the decreased heating capacity possible due to accumulation of refrigerant in the condenser and increased fan power consumption; respectively. For the developed system; the optimum refrigerant charge was observed to be 1650 grams and 840 rpm of condenser fan speed (60% of the full speed) and the appropriate operating ambient temperature of 20 °C. At this point; the COP of the overall system and the heat pump cycle were 3.75 and 5.20; respectively;
