Abstract : This paper exhibits the experimental study of the use of waste heat from domestic refrigerator for drying clothes. A 0.4m 3 capacity drying closet with a 100W blower was fitted to the back side of an LG refrigerator which contains the condenser that emits waste heat. Wet clothes of weights 1.32kg, 1.96kg, 2.89kg, 3.12kg and 4.10kg were hung in the drying closet in succession to dry when the refrigerator was in operation. Air flow temperature, drying closet temperature, hot air velocity in the drying closet, relative humidity and drying time were measured. The drying characteristics and performance of the drying closet were evaluated. The results of the study revealed that wet clothes of weights 1.32kg, 1.96kg, 2.89kg, 3.12kg and 4.10kg were respectively dried in 55, 65, 100, 105 and 130 minutes. The drying rate is in the range of 6.02kg/min to 11.06kg/min. Specific moisture extraction rate varied between 0.752kg/kWh and 1.833kg/kWh and drying efficiency of the closet varied between 48.8 and 63.1%.Keywords : Waste heat, refrigerator, clothes, drying
