Abstract

Due to high humidity, high air temperature and hazardous compounds including chlorine, INDOOR SWIMMING POOLs are called an unhealthy environment. Therefore, the pollutants’ concentration, relative humidity and THERMAL COMFORT conditions must be simultaneously considered in designing the AIR CONDITIONING systems of INDOOR SWIMMING POOLs. In this study, a new approach has been presented for concurrent modeling of water evaporation mechanism, chlorine concentration level, occupants’ thermal sensation and temperature and velocity fields in a championship-size INDOOR SWIMMING POOL. In this regard, a new algorithm has been developed in order to apply adaptive boundary conditions at water-air interface in the pool. In the mentioned pool, the air enters the environment through a linear ceiling diffuser at temperature of 35oC, relative humidity of 30% and air exchange rate of 4 times per hour. The results show that the distribution of temperature, relative humidity and concentration of chlorine contaminant are significantly dependent on the height from the water surface. So, the volumetric average of relative humidity from the floor to 0.5m height is about 62%; while the volumetric average of relative humidity in the occupied zone is about 50%. Moreover, results indicate that in the distance of floor to 0.5 m height, the mean value of chlorine’s concentration is about 60% larger than its mean value in the occupied zone. Also, the temperature field and distribution of THERMAL COMFORT index are significantly dependent on the height.
