Measurement and evaluation of the indoor thermal environment in a large domed stadium

This paper describes the measurements and evaluation of the indoor thermal environments in a large domed stadium. This stadium was built mainly for pr ofessional baseball games, but it has a lot of other purposes. It will be u sed not only for many sport games but also for various entertainment events . To satisfy such purposes, various intelligent mechanical systems were equ ipped to control and create a suitable space and environment without consum ing excessive energy. A multi-zonal air-conditioning system with an under-s eat supply of conditioned air and displacement ventilation is one of these. Measurements, including temperature distribution, humidity, air flow and o utdoor weather conditions, were carried out for three seasons, with each me asurement period lasting for a week. In this paper, the results during the summer are discussed. The results show that the horizontal temperature dist ribution indicates that the air-conditioning system separates the space eff ectively and that each zone can run well separately. The vertical temperatu re distribution also indicates that the under-seat supply air-conditioning system provides air-conditioning to a limited area, or to the occupant zone only.
