清洁采暖背景下的分散供热方式选择

The choice of decentralized heating under the background of clean heating

对6种分散供热方式(电空气源热泵、电污水源热泵、电地源热泵、燃气空气源热泵、燃气锅炉和生物质锅炉)的适用性、环境性和经济性进行了对比分析。结果表明电热泵供热方式因其较高的能效比使其在经济性方面表现出明显的优势,且当其电能来自经过超低排放改造的热电厂时,其污染排放指标也低于其他能源形式。

The applicability,environmentality and economy of six decentralized heating modes(electric air source heat pump,electric sewage source heat pump,electric ground source heat pump,gas air source heat pump,gas boiler and biomass boiler)were compared and analyzed.The results show that the electric heat pump has an obvious advantage in economy because of its high energy efficiency ratio,and when its power comes from the ultra-low emission thermal power plant,its emission index is lower than other forms of energy.
