Sorry, Benncool and coolwhip, I mean the dehumidifying ability about the coil. But I would like know how the fin's thickness affect it, rather than the fin space.

Sorry, Bencool, I mean the dehumidifying ability about the coil. But I would like know how the fin's thickness affect it, rather than the fin space.

I am wondering how to answer this question: how the fin's thickness influence the humidifying ability of a fan coil, provided that the face velocity is kept constant?

Sorry, I made a mistake.It...

I already understood the basic principle for motor speed varing. If someone want to get the answer, I'd like to post it. By the way, I do not think the " site supporter' way is a better way for...

The variable speed fans is usually small fans in air conditioner. Some people say varying its speed by changing the number of poles, but others say by changing the winding resistance then getting...

I mean the principles for it, for example, variable frequence or number of poles.
