Résumé

The heat pump is widely used recently. For high thermal comfort and the decrease of start-stop loss, the continuous capacity modulation of heat pump becomes necessary. A novel capacity modulation method for the scroll compressor heat pump based on refrigerant injection and release technologies is advanced. The experiments indicate that the refrigerant injection increases the heating/cooling capacity by 21.9/21.4%, enhances the heating COP/cooling EER by 5.6%/9.0% when the glycol inlet temperature of condenser and evaporator fix at 40? and 0? respectively; The refrigerant release decreases the heating/cooling capacity by 26.6/31.4%, enhances the heating COP/cooling EER by 16.0%/8.4% when the condensing and evaporating temperature fix at 40? and 1.7? respectively. The technology combining refrigerant injection and refrigerant release is a remarkable capacity modulation method for the scroll compressor heat pump, which can modulate the capacity continuously within a wide range as well as increase its energy efficiency ratio.
