Hello, I am trying to figure out how to effectively cool a control cabinet which has a VFD in it. And I don't want to do this with an online heat transfer program. I would like to understand the equations which consider input heat and air flow.
So, here's the data:
- I have a vented enclosure with an internal volume of 3.72 square meters.
- There is a VFD in the enclosure which produces 1500W of waste heat.
- The enclosure has a fan capable of moving 100 cfm (0.472 cubic meters per second)
- The ambient temperature outside the enclosure will be 32 C.
Assuming that there is no heat transfer through the walls of the enclosure, and there is no heat source other than the VFD (no sunlight or nearby machinery), what will be the approximate temperature inside the enclosure? Please help me out and explain your answer.
thanks, Andy
