污水源热泵热能经济技术分析

Cost-effectiveness analysis of sewage source heat pump

污水源热泵是一种以城市或工业污水作为热源/热汇的空调系统。文章介绍了污水源热泵的工作原理和性能特点,利用财务净现值法和动态费用年值法对污水源热泵和风源热泵系统进行了经济技术对比分析;结果表明,采用污水源热泵可以大幅降低固定资产投资,减少能源和水资源消耗,具有较大的经济和社会效益。

Sewage source heat pump （SSHP） utilizes sewage as source for heating and cooling. The paper introduces the working principle and the performance characteristics of the SSHP and compares the SSHP with the air source heat pump by the financial net present value method and the annual cost method. The result shows that using the SSHP can reduce the fixed assets investment and decrease energy and water resources consumption, thus big economic and social benefit can be achieved.
