Résumé

The purpose of this study is to enhance the heating capacity and increase COP under the frosting condition during heating operation of small capacity air-to-air heat pump. We applied an electric heater in front of outdoor unit of heat pump instead of indoor unit as usual. When the outdoor temperature is 2°C/1°C (DB/WB), the present heat pump turns on the electric heater in outdoor unit. The heating capacity increases 38.0% and COP increases 57.0% in comparison with those of conventional heat pump. When the outdoor temperature is 4°C/2°C (DB/WB), the electric heater is in ON/OFF mode according to the temperature of the evaporator. The heating capacity increases 9.1% and COP increases 71.1% in comparison with those of conventional heat pump. [Reprinted with permission from Elsevier. Copyright, 2009].
