复合热泵热水系统的经济环保效益分析

Economic and Environmental Benefit Analysis of Composite Heat Pump Hot Water System

针对某高校洗浴中心的空气源和污水源复合热泵热水系统,本文从经济性和环保性两个方面出发,比较分析复合热泵热水系统与传统热水系统的优劣性。结果表明,复合热泵热水系统能耗最低,热水能耗仅11.8 kWh/t;系统初投资高,但运行费用低,费用年值为67.5万元,仅约燃油锅炉的38%,电锅炉的55%;与燃气锅炉相比,环保效益不明显,但远小于其他用电热水系统。

Aiming at the air source and sewage source composite heat pump hot water system of a college bathing center,this paper analyzes the advantages and disadvantages of the composite heat pump hot water system and the traditional hot water system from two aspects of economy and environ-mental protection.The results show that the composite heat pump hot water system has the lowest energy consumption,the hot water energy consumption is only 11.8 kWh/t;the initial investment of the system is high,but the operating cost is low,the annual cost is 675,000 Yuan,only about 38%of the oil-fired boiler,55%of electric boiler;compared with gas boilers,environmental benefits are not obvious,but much smaller than other electric water heating systems.
