Thermal comfort and climate control
- Takenaka Corp., Osaka (Japan)
This article reports on ice thermal storage and heat recovery in Japan`s Crystal Tower. Crystal Tower, a curtain wall-faced, 37-story intelligent building with two basements and a total floor area of 925,630 ft{sup 2}, was completed in August 1990 in Osaka, Japan. It is located on the north side of Osaka Castle Park on a site surrounded by water and trees. In view of the stringent supply of electricity in summer, and of the fact that cooling accounts for 60% of peak daytime demand during the summer, there is clearly a demand for a new climate control system that can balance the supply and demand of electricity load by using thermal storage to shift the peak. Having considered all these factors, it was decided to use an ice thermal storage system to cool the building. It also was decided that the air-conditioning system would use natural refrigerant circulation by means of low-temperature brine.
