变配电室降温方式的适应性选择

摘要

Electrical transformation and distribution rooms have large heat generation,which need cooling by ventilation and air conditioning.The cooling mode is often determined by empirical estimation,resulting in unreasonable design,high initial investment or operating cost,and so on.Aiming at the characteristics of heat generation in electrical transformation and distribution rooms,combined with the climate division of China,puts forward a quick search table of air change rate and air conditioning cooling load for similar design reference.%变配电室发热量大,需要通风空调降温.确定降温方式时,工程上往往凭经验估算,导致设计方案不合理,造成一次投资或运行费过高等问题.针对变配电室的发热特点,结合我国气候分区,提出了换气次数/空调冷负荷速查表,供同类设计参考.
