四、在非干燥地区IEC的应用前面探讨的IEC的应用都是对干燥地区的。对非干燥地区当室外空气的含湿量高于室内空气时,单靠IEC系统是无法满足室内空调要求的,因为当以室外空气用作为一次和二次空气时,IEC系统没有去湿能力,它不能将室外空气的含湿量处理到低于室内空气。其次,对比较潮湿的地区,由于室外空气的干湿球温差不大,通过间接蒸发冷却也不能获得满意的冷量。为了解决这一问题,可以采用室内排风 Fourth, the application of IEC in non-dry areas IEC applications discussed earlier are for dry areas. For outdoor areas where the outdoor air has a higher moisture content in non-dry areas, the IEC system alone can not meet the requirements of indoor air-conditioning because the IEC system has no dehumidification capability when used as primary and secondary air with outdoor air, It can not treat outdoor air moisture below indoor air. Second, for relatively humid areas, due to the small difference in temperature between the wet and dry bulb of outdoor air, satisfactory cooling capacity can not be obtained by indirect evaporative cooling. In order to solve this problem, you can use indoor exhaust
