太陽熱利用給湯システムにおける貯湯槽内の温度性状と補助熱源機の稼働制御に関する研究

The authors manufactured a hot water supply system with solar panels. Water in a storage tank was heated by the fluid path through solar panels and a heat-pump as a back-up heater. This system was operated in three modes through a year, and following results were obtained. (1) In the case that using pattern of the hot water was based on an energy conservation handbook, the maximum hot water demand occurred in supplying to a bathtub. Then for the maximum demand it was necessary to prepare 300l hot water which was more than 50℃, in the storage tank. In other time, it was necessary to prepare 100l hot water which was more than 50℃. (2) The efficiency of solar energy to heat water in the storage tank was obtained. The prediction control of heat-pump operation was possible by using neural network. Furthermore, the authors showed an operation control method to supply for the maximum demand of hot water and to conserve energy.
