那完蛋了,我家筒灯、射灯宛如群星璀璨。这几年我就三天两头换灯泡了,几乎之前的灯泡都换了一遍了
不过暖空气一定就=湿空气么?我那次就是把屋里的暖气送进阁楼,等于是烘干了那些钉子头,后来不是就再也没有嘀嗒水了么?
太麻烦了,弄个房子天天净伺候它了
一个老式的筒灯一天可以排1/3加仑的水到阁楼里。
How much of an impact do recessed fixtures have on the total air leakage of a typical home? According to a 1992 study performed by the Mechanical Engineering Department at Penn State University, shortly after the new ICAT-Rated fixtures became widely available, it is estimated that one conventional Non-IC or IC-rated fixture can be responsible for the loss of between $5 and $30 per year worth of energy and can dump about one-third of a gallon of water daily into a cold attic.
过去的筒灯还故意开些口散热,后来的 IC rated (insulation contact 可接触保温材料)也不一定密封,顶楼筒灯要用 ICAT (又可以接触保温材料又密封)。
钉子头的冷凝水暂时没了,但是木材和灰板里的水分应该很高,会发霉的。如果问题根源没找到,今年冬天还会有问题。
你这个冷凝水问题很严重,除了检查筒灯也要检查阁楼里面那些暖通设备和管道有没有漏风。找个专业人士好好彻底检查一下。
