Abstract Air source heat pump water heater is used in a similar heat pump room air heating operation mode, the system of the lower lateral condensation temperature water heating products。 Rated operating conditions, the heat pump water heater can usually get burned several times in the same power and water temperature of the same electric water heater of hot water, has the good power saving effect。 This article used for making living hot water for household air source heat pump water heater running conditions, system configuration scheme, choice of refrigerant and electrical safety technical requirements, design theme is efficient one-piece air source heat pump water heater。 the paper first introduces the air source heat pump water heater working principle and characteristics, as well as heating conditions were related to thermodynamic calculations。 Analysis refrigerant selection principles and constraints and finalize R134a as refrigerant; through displacement and cooling capacity and performance characteristics considering the choice of a scroll compressor Bitzer all closed  scroll  compressor,  Model  。  Known  cooling  conditions:  cold  water     inlet

temperature  15 ℃ ,  cold  water  temperature  55 ℃ ,  ambient  temperature  20 ℃ 。

Considering the election and straight tube condenser tube integral film sets evaporator, and condenser and evaporator design calculation。 In the electrical control and the corresponding auxiliary equipment is also a brief introduction。 Finally, air-source heat pump water heater performance testing, design requirements and performance factors measured are satisfied。
