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

摘要: 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。

Abstract: 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.
