Description

This paper describes the effectiveness of residential combined heat and power (CHP) systems by using load following gas engine in cold regions for energy conservation. First, evaluation of the basic performance of gas engine CHP system was executed. The AC electrical efficiency and heat recovery efficiency were 21.6% and 53.9% at approx. 1.2 kW, and the high performance was maintained at lower load conditions. Second, the dependence rate on electric power of each house was more than 80%. Finally, comparison with a rated output gas engine and the optimum energy demand conditions for the load following gas engine were shown by numerical analyses.
