Hi there,
Can anybody help me with this question?

If a system is designed for a certain capacity and the evaporator (with fan) is also selected and say it has 100mē of heat transfer area then, if the same application is to be used with an evaporator without fans then what should be the heat transfer area compared to the one with fans? Is there any relations?
What I heard is that the area with fans should be multiplied by 2.5 or 3 which gives the surface of the evaporator without fans. Is this correct?
Cheers
