Micro combined heat and power(MCHP)is an effective way of energy conservation.This article mainly aims at establishing a thermodynamic model and analyzing the energy efficiency of micro congeneration system by setting the reference object.Analyze the impact of user's heat to power ratio and purchasing electricity quantity from public grid on CHP energy saving potential under integrating the building load.In this paper
analysis was carried out by importing the MCHP into an office building based on the measured heating and power load characteristics.Calculation was found that the average daily energy saving ratio can reach up to 22.76%-23.16%
the unit exergy efficiency can reach 48.06% in congeneration system during the heating season.
