B-63 空冷チラーを用いた冷媒サブクールシステム

抄録

Air-cooled chiller-units are popular facilities of central air conditioning system of office buildings. We applied Sub-cooling system, an energy-saving technology of multiple packaged air conditioning units for buildings, to this facility. This system is not only efficient but also less harmful to air heat exchanger of air-cooled chiller units. We introduced this system to a new building, operated for 4 months, and verified the advanced performance of this system. As a result, it was confirmed that the cooling capability increase by 12-13%, electric power consumption decrease by 12-15% (outdoor air temperature: 32.5〜30℃, cooling load factor: 20〜50%).
