大连某疗养院海水热泵系统与传统空调方案的技术经济对比分析

Technical and Economical Evaluation of Using Seawater Source Heat Pump and Conventional System for Heating and Cooling in Dalian Sanitarium

沿海地区是利用海水源热泵进行供热供冷的理想位置。本文就大连地区如何利用海洋热资源进行了分析。首先对海洋气候条件下应用此项技术的要求和方案设计进行了讨论,然后结合实际工程(热负荷1.2MW,冷负荷1MW),对其可行性进行了研究,对初投资和运行费用进行了估算。结果表明,由于该项目所处位置和此项技术使用特点,海水源热泵系统在经济和技术上都是可行的。

Coastal areas are ideal sites for using the seawater-source heat pump technology （SWHP） to achieve cooling and heating. This paper presents a study on the utilization of ocean thermal energy in Dalian. Firstly, the technical requirements and the scheme design under the marine climate condition were discussed. Secondly, a feasibility study on a proposed district energy project in Dalian with an estimated 1.2MW heating load and I MW cooling load was carried out. In addition, the total initial investment and operation cost were estimated. It could be concluded that this system was both technically and economically feasible with the favorable geographical location and operational conditions.
