A new type of air source heat pump water heater system with scroll compressor through middle
injection of economizer in the course of compression is put forward operating reliably long and efficiently in
low temperature in this study. The experimental prototype is set up, System fundamentals and the operation
modes are introduced, Experimental research on operation characteristics of the unit in three different operation
conditions is done in the lab of enthalpy difference; Heating capacity and COP were 8.84 kW and 2.43,
respectively under the condition of environmental temperature of which is -7 and -8ºC, respectively for dry bulb
temperature and wet bulb temperature. The result shows that the unit operates reliably long and that heating
capacity and COP of the unit are improved in low temperature.
Key words: Air source heat pump water heater, economizer, low temperature, medial injection, , ,
