| Abstract: | Small HFC-32 air-cooled water chilling( heat pump) unit and water( ground) source heat pump unit is developed. The performance of air-cooled water chilling( heat pump) unit under series conditions are tested,including nominal cooling condition,nominal heating condition,maximum cooling load condition and maximum heating load condition. The performance of water(ground)source heat pump unit for water-loop application,ground-water application and ground-loop application under series conditions are also tested,including nominal cooling condition and nominal heating condition. The conclusions indicate that compared with similar HFC-410 A unit,the cooling( heating) capacity and power consumption of HFC-32 unit are higher than HFC-410 A unit,the energy efficiency for HFC-32 unit is a little lower than HFC-410 A unit,and the compressor exhaust temperature of HFC-32 unit is 16. 5 ~ 19. 5℃ higher than HFC-410 A unit. |
