Recently, research and development of micro co-generation system is conducted actively. However, few studies were reported on the combined thermal efficiency based on the actual data measured all through the year. In this paper, firstly, we report actual data based combined thermal efficiency evaluation of micro gas turbine centered micro co-generation system especially focused on ambient temperature effect. During the measurement we found temperature fluctuation of heat transfer medium under the condition that the ambient temperature is less than 28 degree Celsius. Then, secondly, we report the analysis of this phenomenon by formulating the relation of heat balance taking account of nonlinearity of valve characteristics.
