海水制冷热泵装置的节能分析与材料优选

Analysis on energy saving and materials of seawater refrigeration equipment and heat pump

海水具有温度相对稳定、能量蕴含量大等特点,本文对近海地区采用海水作为制冷热泵冷热源的节能特性进行了系统的分析,对耐海水腐蚀金属材料的研究情况进行了介绍,对天津地区适宜用作海水换热器的材料进行了优选,为近海地区高效制冷热泵装置的设计与应用提供了参考。

There is large quantity of energy in seawater whose temperature change is relatively small in different seasons.In this paper,the energy saving principle of refrigeration equipment with seawater as heat sink and heat pumps with seawater as heat source is analyzed,and materials which are suitable for seawater heat exchanger in Tianjin are selected.Results and information given in this paper can be an important help to design and applications of high efficiency refrigeraiton equipment and heat pumps.
