Abstract

Solar-assisted cooling technology (SACH) was developed using a solar heat-driven ejector cooling system (ECS) to cool the condenser and reduce the power consumption of an inverter-type air conditioner (IAC). IAC provides cooling capacity for cooling load of a room, while ECS acts as a means of energy saving for IAC. A perfect system matching design of SACH is difficult since incident solar radiation is unpredictable and unstable. At high solar radiation, the cooling capacity provided by ECS can be larger than the condensing heat of the IAC. A modified SACH (named "SACH-y") is proposed in the present study, which adds another evaporator of the ECS to supply additional cooling capacity to the room. The measured net electrical COPe of SACH-y (using an IAC with COP 3.25) reaches 5.54. If the modern advanced IAC with COP 5.7 was used, the total net COPe will exceed 10.
