The feature of stadiums is that depth is large, and space is large, and volume is large.Because venue depth is large, the mode that surrounding is sent point, easily causes surrounding in shop to have the gradient of larger temperature, wind speed, cleannes to center, and, the closer to venue center, comfort level is poorer, and indoor air quality is poorer.Trace it to its cause, side feeding type air port is too far away apart from venue center, and wind speed can not be very large, and flowing of gas can not arrive venue center, therefore forms larger thermograde, and can not effectively foul atmosphere be discharged.
Stadiums depth is large, and space is large, bulky feature, and the installed capacity that makes venue air-conditioning is very large.The input of air conditioner facility is also very large.In order to pursue good looking appearance uniqueness, strengthen natural lighting in recent years, large area adopts transparent glass curtain wall and printing opacity dome, makes heat transfer across wall amount large, and heat insulation effect is poor.This just makes summer air conditioning load large.In order to save operating cost, summer air-conditioning ventilating system is not in most cases opened or is opened less, and result makes air quality and environmental degree of comfort be difficult to satisfy the demand, student for a long time under this condition athletic meeting cause the even danger such as heatstroke of anoxic.
The Northwest's air is dry, in venue design, does not also have humidification to consider, the source of students of colleges and universities is from all corners of the country, and the student of southern area lives at ordinary times and is not suitable with especially the dry of northwest, and moves under dry environment, and health is uncomfortable especially.
In sum, stadiums need improved problem mainly to comprise these aspects aspect air conditioner ventilating system at present: the first, and the improvement of Air Distribution, ensures environmental amenity and wholesomeness in shop; The second, change refrigeration unit refrigeration modes, reduce installed capacity, save power consumption, reduce energy consumption; The 3rd, air wetting function is reasonably set, make the subenvironment of venue be more suitable for sporter's health demand.
