How to estimate the heat generated from the wash station?
(OP)
I am working on a project, and need to estimate how much heat is generated from the wash station using hot water spray at 100 F. The overall flow of the hot water spray is 5 gpm. If the wash station is exhausted at 3 cfm/sq ft, do I still need to cool the space? The wash station is enclosed in an air-conditioned space and very little cooling load from lighting and people. Thanks for help!





RE: How to estimate the heat generated from the wash station?
You need to provide enough air (either make-up or transfer) to balance the air being exhausted. Most likely the wash station is designed to be NEGATIVELY pressurized to keep fumes and oder from escaping the area. Therefore, the exhaust air CFM will be more than the supply, makeup air or any transfer air CFM in that space. The CFM amount depends on your assumptions and/or design criterions.
This is my general understanding of the situation...Hope it a start in the right direction for you.

What is the temperature of the space directly outside of the wash station?
Can you use transfer air and accept a slightly higher temp in the wash station than in the adjacent space? If you position a transfer air duct to impinge on the wash station operator and then exhaust it above the area that creates most of the heat gain, it might be acceptable solution.
