利用跨季节储热水体余热调峰供热技术经济分析

Economic analysis of seasonal thermal storage and peak regulation for heat supply of waste heat

在“双碳”背景下,供热行业逐渐从煤炭供暖向清洁采暖转型。但短时间内煤炭仍为供热主力,本文以清洁能源作为调峰热源,对比了几种清洁采暖调峰系统的经济性。提出了一种集成吸收式热泵的余热跨季节储热调峰供热系统。相对于燃汽调峰供热系统,投资回收期可降至3.59年。研究结果为发展余热供热提供了参考。

Under the background of "carbon peaking and carbon neutrality goal",the heating industry has gradually transformed from coal heating to clean heating.However,coal is still the main heat supply in a short period of time.In this paper,the economy of several clean heating and peaking systems is compared by using clean energy as peak heat source.A heat supply system with integrated absorption heat pump for waste heat seasonal storage and peak regulation is proposed.Compared with the gas peaking heating system,the payback period can be reduced to 3.59 years.The results provide a reference for the development of waste heat supply.
