Abstract
Most of the energy in the university campus is consumed by air-conditioning units and therefore it must be managed for saving energy. In recent years, adoption of the multi-split air-conditioning system has increased, but the actual situation of its operation has not been clarified and hence, rational examination cannot be conducted reading its design and use. After performing operative fact-finding of the air-conditioning system at Tokyo University, the actual situation that capacity was excessive and driving of the low load factor caused an efficiency drop became clear. Therefore, an actual survey of buildings subjected to modification was conducted by defining their own capacity selection criterion in order to correct the excessive capacity. The examined operations were reported in order to achieve more energy saving and realize the concept of equipment selection.
