【Abstract】 Against the phenomenon that air source heat pump water heater can not work steadily, this paper comes up with a air source heat pump system with a flash evaporator, and it solves the shortcomings which the traditional heat pump system encounters to some extent. In addition, this paper makes theoretical calculation for heat pump cycle which uses R22 and R410A respectively, and analyzes the results.更多还原
