不同空调热源的一次能源效率分析与比较
Analysis and comparison of primary energy efficiency between different heat sources for air conditioning
摘要：
针对目前能量利用效率分析方法的不足，在对热电循环中热量和电量的一次能源消耗率进行分析的基础上，提出了热量和电量的一次能源消耗量的折算方法。结合工程实例，对空气源热泵、集中供热、深井水水源热泵、地埋管地源热泵等常用空调热源方式的一次能源效率和影响因素进行了分析和比较，结果表明，在给定情况下，热网供热一次能源效率高于热泵。建议大规模集中供热应优先采用热电联供的方式。
Abstract：
In view of the deficiency in current analysis methods for energy use efficiency, puts forward a conversion method of primary energy consumption of heat and electric power on the base of analyzing the thermoelectric cycle. Taking a project as an example, analyses and compares the primary energy efficiency and influencing factors of common air-conditioning heat sources, such as air source heat pump, central heating, deep well water source heat pump, ground source heat pump etc. The result shows that the primary energy efficiency of heating network is higher than that of heat pump under given conditions. Suggests that heat and power cogeneration should be adopted as a priority mode for district heating.
