狭小戸建住宅における PV 発電を用いた温水式床暖房と潜熱蓄熱建材併用による冬期の空調消費電力削減効果

Phase Change Material utilizes direct gain to absorb solar radiation during the day and dissipate it at night, resulting in energy savings. However, narrow-detached houses with little solar radiation acquisition due to neighboring buildings may not absorb heat sufficiently, resulting in low room temperatures, and there is little knowledge of PCM utilization in such environments. In this study, the effect of reducing air conditioning power consumption in winter of the system of storing heat in PCM by hydronic floor heating using solar power generated on the roof surface for its own consumption is verified from a systematic heat load simulation.
