项目摘要

The purpose of this project is to investigate how much peak electric demand in the day that is cut down by applying earth heat storage system using surplus electricity at night and photovoltaik system to small size buildings and residences. We constructed a residence so call "the Energy Producing & Saving House" in Kumamoto City. We have been carrying out this study since 1994. The results obtained at this project are as follows ;The results of electric generation efficiency during the period from 1996 to 1997 were presented.Regression Analysis was carried out to predict electric generation of the PV system under various weather conditions.After examining the results of the experiments mentioned above, the overall efficiency of the earth heat storage system is estimated to be approximately 1.5 times of electrical energy consumption of the chilling unit at night. It became clear, that the earth heat storage system serves as a heat source for space heating or cooling during daytime. For electlical power consumer In residences or small-scale buildings, the electricity costs can be reduced due to the lower user rate at midnight. Moreover, the system also alleviates the load on the city's power grid during daytime peak periods.

本项目的目的是调查在小型建筑物和住宅中应用利用夜间剩余电力的地热储存系统和光伏系统可以减少多少白天的峰值电力需求。我们在熊本市建造了一个被称为“能源生产和节约之家”的住宅。自1994年以来，我们一直在进行这项研究。该项目取得的成果如下：给出了1996 ~ 1997年的发电效率试验结果，并进行了回归分析，预测了不同气象条件下光伏发电系统的发电量，对试验结果进行了检验，结果表明，太阳能光伏发电系统的发电量与气象条件下的太阳能光伏发电系统的发电量基本一致，太阳能光伏发电系统的发电量与气象条件下的太阳能光伏发电量基本一致。估计地热储存系统的总效率大约是制冷单元在夜间的电能消耗的1.5倍。很明显，地球热存储系统在白天用作空间加热或冷却的热源。对于电力用户在住宅或小型建筑物中，由于午夜的用户费率较低，因此可以降低电费。此外，该系统还可以在白天高峰时段减少城市电网的负荷。
