Abstract
A gas defrosting method is disclosed which provides a distinct two-step process for defrosting a frosted evaporator. In deliberate fashion, the method assures that only refrigerant vapor returns to the compressor and thereby protects the compressor from damage due to receiving liquid refrigerant. The method optimizes the heat transfer process by maintaining full refrigerant flow through the condenser and by controlling the vapor in a nearly saturated state, high density state. In addition, the method strives to minimize the compressor power expended during the defrosting process.
