you probably dont care but does anybody know of a way to get back into an Instagram account? I stupidly lost my login password. I appreciate any tricks you can give me!
这个我想补充一下,一般air make up unit 是用在商业厨房上的,所有的餐馆厨房都配有make up air unit,因为体积大,都安装在屋顶上。 抽油烟机都会或多或少给家里造成negative pressure,但很多老房子因为没有那么密封,所以没什么关系。在1993年之后建的房子,我们统称为tight house,这种房子的特点就像豆壳视频里所说的那样,密封性很好,还有vapor barrier。这种情况如果房子里有负压产生,我们可以用HRV做一个补充。冬天家里门窗紧闭,不仅仅是抽油烟机,还有所有厕所里的抽气机都会造成房子负压。
Agree. Carbon monoxide poisoning from heating elements like hot water heater is real. In a negative air pressure situation, carbon monoxide from a hot water heater can be sucked into living space.
The manufacturers of HRV equipment advocate balance and will not discuss makeup air for any appliance. The units are designed to recover energy while exhausting foul air and replacing it with fresh outdoor air. www.greenbuildingtalk.com/Forums/tabid/53/aff/14/aft/82515/afv/topic/Default.aspx
