住宅における予冷予熱運転による太陽光発電電力の有効利用に関する実証研究

摘要

The housing section in Japan is promoting the introduction of renewable energy. However, it has problems such as surplus generation during alow load period and there could be a rise in voltage due to reversed power flow. Therefore, there is a need to use the generated surplus energy effectively. The aim of this study is to evaluate the effects of the precooling and preheating operation. To this end, we measured indoor environmental fectors, energy consumption, and skin sur&ce temperature and heat loss using a thermal manikin under ten conditions with different air conditioning in house with higher heat capacity.%夏季と冬季の予冷熱運転がPV発電の自家消費率及び熱的快適性に与える影響の把握を目的として、熱容量が大きく高断熱な対象住宅において空調運用条件が異なる10条件で物理環境•電力量•サ一マルマネキンを用いた温冷感予測の実験を行った。また、発電量などの実験データを用いてHP給湯器の昼間運転をシミュレーションし、比較•分析を行った。以下に本報で得た知見を示す。
