寒冷地区分布式清洁供暖技术研究进展

Research Progress of Distributed Clean Heating Technology in Cold Regions

分布式清洁能源已应用于北方寒冷地区供暖中,本文分析了我国北方现有分布式清洁供暖技术的优劣,包括太阳能供暖、空气源热泵、污水源热泵、土壤源热泵、中深层无干扰地热和天然气供暖等,并对其在清洁供暖中存在的共性问题进行分析,探讨解决路径。研究发现:太阳能供暖多作为常规采暖的辅助热源;准双级压缩可解决空气源热泵室外机结霜问题;地源热泵可为唯一供暖热源方式,应用受周围可提供热源的限制;天然气供暖热保证率好,造价高。受国家鼓励机制影响,多能互补、系统集成将是今后清洁供暖领域发展的热点。

Distributed clean energy has been applied in the heating of cold areas in the north.The advantages and disadvantages of the existing distributed clean heating technologies in the north of China,including solar heating,air source heat pump,sewage source heat pump,ground source heat pump,medium-deep non-interference geothermal,natural gas heating,etc.and the common problems in the clean heating are analyzed,and the solutions are discussed.The results show that,solar heating is mostly used as an auxiliary heat source for conventional heating;quasi-double-stage compression can solve the frosting problem of the outdoor unit of the air source heat pump;ground source heat pump can be the only heating source,and its application is limited by the heat source available around;the thermal guarantee rate of natural gas heating is good,and the cost is high.Influenced by the national incentive mechanism,multi-energy complementation and system integration will be the focus of the development ofclean heating in the future.
