Description
This paper exhibits theexperimental study of the use of wasteheat from domestic refrigerator for drying clothes. A 0.4m3 capacity drying closet with a 100W blower was fitted tothe back side of an LG refrigerator which contains the condenser that emitswaste heat. Wet clothes of weights1.32kg, 1.96kg, 2.89kg, 3.12kg and 4.10kg were hung in the drying closet insuccession to dry when the refrigerator was in operation. Air flow temperature, drying closettemperature, hot air velocity in the drying closet, relative humidity and drying time weremeasured. Thedrying characteristics and performance of the drying closet wereevaluated. The results of thestudy revealed that wet clothes of weights 1.32kg, 1.96kg, 2.89kg, 3.12kg and4.10kg were respectively dried in 55, 65, 100, 105 and 130 minutes. Thedrying rate is in the range of 6.02kg/min to 11.06kg/min. Specific moisture extraction rate variedbetween 0.752kg/kWh and 1.833kg/kWh anddrying efficiency of the closet varied between 48.8 and 63.1%.
