摘要
本文以节能节材为目的,对水-水中高温热泵系统进行了优化设计,以经济参数F为目标函数对系统进行经济性评价。本文将水泵功率考虑在内,并研究了过热度,过冷度,两器水流量以及两器的面积分配对F的影响,旨在更全面的评价水-水热泵性能,实现系统各部件的最佳匹配。
Optimal design is done for water to water moderate and high temperature heat pump system from the viewpoint of saving energy and materials. A parameter F is defined as the objective function to make economic evaluation for the system. In this paper, work cost of water pump is taken into consideration, and some other factors influencing F are analyzed, which include superheat, subcooling, water flux of the heat exchanger and the distribution of the heat - transfer area of the heat exchanger. The aim of this study is to get a better understanding of the performance of water to water heat pump and to obtain the optimal, matching of various components of the system.
