DEVELOPMENT OF SYSTEM FOR REDUCING FRESH AIR LOAD BY USING SOLAR COLLECTOR AND PCM IN COLD REGION

Numerical analysis of system efficiency by using characteristics of elements

Abstract

The number of house with thick insulation and air tightness is increasing in cold climate region to decrease heating energy and to save daily life cost. Decreasing fresh air load is important to save heating energy in such houses. The purpose of this study is to develop pre-heating system by using solar air heat collector with thermal storage system. First, we examined the performance of the solar air heat collector and thermal storage system. Second, we made the numerical model. Third, we analyzed the possibility and the application of the system by using the numerical model.
