Summary

Because Japan is consuming a lot of energy and most of energy supply id depending on other countries, more efficient energy saving technology is required. Energy consumption of industrial and service sections in Japan account for about 60% of the total energy consumption, and about 30% of the consumption in these sections is consumed by building heat source system. "Total optimal control system for heat sources" (hereinafter referred to as "TOCS") have been developed, and it can reduce energy consumption to 50% or less. There are many energy saving systems, such as heat recovery system producing cold and hot heat simultaneously, cooling towers using outside air as a cooling heat source without chilled water during the free cooling operation and refrigerators with inverters working efficiently during the partial loading operation. But in such systems, energy efficiency changes according to the amount of required cool and warm heat and condition of outside air because all instruments of heat source system is connected. By adopting the "TOCS", it can operate them co-ordinately to maximize the energy efficiency.
