Description

The purpose of this study is to clarify the effect of building and system factors on the thermal performance of the solar floor heating system with Water Floor (water heat-storage floor) by simulation analysis. The examined building and system factors are the heat capacity of Water Floor, the material of heat-storage floor, the thickness of thermal insulation of building envelope, climate etc. From the results, it was found that Water Floor can raise generally 20% of comfortable time rate and is effective to raise thermal environment level, comparing to the concrete floor and plywood floor, and so on.
