Abstract
ZEH (Zero Energy House) is the prospective model of housings which enables the reduction of energy consumption in domestic uses. The authors are developing a Stirling engine solar power generation system using a hybrid heat source, which produces electricity and warm water from solar and woody biomass. This paper presents a 500W Stirling engine generator installed in that system. It is a two-piston type Stirling engine driven by a crank mechanism and has a generator built-in. In addition, dependency on He gas mean temperature in a hot space of the Stirling engine generator is made clear.
