严寒地区区域供暖系统优化方案技术经济性分析

Analysis of the Renovation Plan of the Existing District Heating System in the Cold Area

严寒地区既有供暖系统改造作为我国老旧小区综合改造和性能提升的重要内容,是缓解我国环境问题和资源紧张的重要途径和关键环节。基于“煤改气”、“煤改电”政策对燃气锅炉供暖系统、空气源热泵复合供暖系统进行技术与经济分析,旨在为我国严寒地区区域供暖提供重要的参考价值。

As an important part of the comprehensive transformation and performance improvement of old residential areas in China,the transformation of existing heating systems in cold areas is an important way and key link to alleviate China’s environmental problems and resource constraints.Based on the policy of"coal to gas"and"coal to electricity",the technical and economic analysis of gas boiler heating system and air source heat pump composite heating system is carried out,aiming to provide important reference value for district heating in severe cold areas in China.
