Total Energy Consumption Optimization Design of Surface-Water Source Heat Pump Systems

Abstract

This paper deals with the study of transmission and distribution energy consumption (TDEC) optimization design about surface-water source heat pump system. Three mathematical model have been established. The fitted polynomials of COP, Ne, Nc were obtained by the MATLAB curve fitting toolbox according to datum from product samples. The differences between two operating states which are constant flow and variable flow were analyzed and compared. Under variable flow operating state it was found that there exists an maximum energy conversation rate12.68% of TDEC; the heat pump unit will consume more than average 8.41% energy, while COP will decline average 7.61%, the mean energy conversation rate of Ne and Nc are 49.38% and 38.86%, the average declination rate of tein and tcout are 17.09% and 5.73% compared with constant flow operating state.
