资源简介：
By operating heat pumps (HPs) in series, it is possible to obtain closer match between working fluid and sink- and source streams, resulting in higher coefficient of performance (COP). For industrial HPs, it was found that serial connection of either two or three units results in an increase in COP and a decrease in net present value (NPV), due to the effects of economy of scale. However, connecting HPs in series may reduce the discharge temperature, which is of particular interest when assessing R717 HPs. Another possibility from serial connection is to mix different types of HP units, in order obtain specific characteristics. The technical and economical working domains were calculated for two serial connections. Both configurations result in an increased working domain for the investigated dual unit serial connections.
