The Evaluation on the Performance of Sea Water Heat Pump System by using Unused Energy

Abstract

With reference to the sea water thermal source heat pump system introduced for supplying heat to the Seaside Momochi Area located in the western part of Fukuoka city, measures for improving the system's efficiency are described first, and then an evaluation of the performance and the energy saving effects of the system are presented. It has been confirmed that the coefficient of performance (COP) under heating and cooling operations of the system reaches 3.46 and 4.86, respectively and the energy saving factor reaches 26% and 47%, respectively.
