Author(s): Shrikant Kathwate, Sachin Kardile, Mohnesh Mandhre
Abstract: This study concerned with a hot gas defrosting method for the removal of frost which formed on the evaporator operating at sub-zero temperatures in an air source heat pump, the performance of unit degrades. Thus alternative defrosting methods are being studied. This paper presents a literature review of the available defrosting methods. The review includes an ongoing efforts by various researchers to develop and design a hot gas defrosting system (HGBS) for an air source heat pump.
