新型可再生能源供热能效对比研究

Comparative Study on Heating Energy Efficiency of New Renewable Energy Sources

以西北某一园区的供热为例,根据该园区的地理位置条件确定太阳能供热、干热岩供热、污水源热泵供热这三种供热方式,并将这三种供热方式与传统供热能源比较,得出了该三种能源方式在经济性和环保性上的优越性,同时也对这三种供热系统进行能效分析,得出从经济性和回收周期来看,污水源热泵系统供热的初期投资费用最低,且具有良好的经济效益,为该园区最适合的供热方式。

Taking the heating of a certain park in the northwest as an example,according to the geographical conditions of the park,three heating modes,solar heating,dry hot rock heating and sewage source heat pump heating,are determined and provided.Compared with the traditional heating energy,the method has obtained the superiority of the three energy modes in terms of economy and environmental protection.At the same time,the energy efficiency analysis of the three heating systems is also carried out.It shows that from the perspective of economy and recycling cycle,the sewage source heat pump system has the lowest initial investment cost and good economic benefits,and is the most suitable heating method for the park.
