5. Find the right climate control product
Required cooling capacity of climate control product
Qe (W) = Qv – k • A • T
T = (Ti - Ta)
---------------------------------------------------------------------------
Example: enclosure with area of 52 ft2 = 4.82 m2
Given: Painted Carbon Steel
Ta = 30°C (Maximum ambient temperature)
Ti = 40°C (Maximum enclosure internal temperature)
Heat load of components: 1000 W (Sum of All heat loss
of components – drives, PLCs)
Qe (W or BTU) = 1000 W - 5.5(W/m2C) * (4.82 m2) * (40°C - 30°C)
= 735 W = 2500 BTU ( q
