Analysis and comparison of primary energy efficiency between different heat sources for air conditioning

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.
