Abstract

Abstract: Propane substituting for R22/R134a has a good future for protecting environment and saving energy. This paper designed and developed a new integral floor heat pump water heater with propane, analyzing from the propaneecharacteristics, system matching, several aspects of safety design, think that propane is a good alternative refrigerant with great advantage, it is the most potential refrigerant of environmental protection in small heat pump, with flammable explosive proposed to pay attention to the design, production and use of process problems.

Key words: Propane, Heat pump water heater, Environmental protection
