An experimental study of using water, methanol, and binary fluids in oscillating heat pipe heat exchanger

Abstract

The aim of this paper is studied experimentally the effect of using oscillating heat pipe heat exchanger as a heat recovery device in the air conditioning system to enhance the dehumidification capability of the cooling coil. Water and Methanol and binary fluid of Water/Methanol used as working fluids with 50% filling ratio. The dehumidification capacity of cooling coil can be enhanced by using oscillating heat pipe heat exchanger by enhancement ratio 25%, 21%, and 17% for Methanol, Binary, and Water respectively. The maximum total energy saved can be reached at 1645 W, 1849 W, and 1932 W for Water, Binary, and Methanol respectively.
