Description

Reducing energy consumption of the hot water supply system plays an important role in considering energy conservation in hospitals, residential buildings and hotels. Acquisition of water temperature data in water supply and distribution pipes in the region is essential to devising an energy conservation plan for the hot water supply system. Based on the statistical yearbook of the water works, we have analyzed water temperatures at 640 purification plants throughout Japan, and developed simplified prediction methods of water temperatures in distribution pipes. We further compared the predicted temperatures with actual temperatures of water in distribution pipes and tested the validity of the prediction methods.
