Small machine shop.
HVAC contractor asked what/how to calculate the cooling load for each machine should be. Supplier of the milling equipment suggested that normal operating load would be 30-50%. All have VFDs. A DuraPulse VFD for 230v 3PH 40HP is rated at 30KW. Is it to simple to just use 15KW for the cooling load?
Using that basis I come up with about 83KW of cooling load, 283K btu, or a bit shy of 24 Tons of cooling just for the machinery in the shop.
