Why climate control?

• Components generate heat (heat loss Qv)

Reduction of the service life according to Arrhenius' law

( )• Service life of components is

reduced when temperature is too high• Examples include:

Find the right climate control product

Required cooling capacity of climate control product

Qe (W) = Qv – k • A • TQe (W) = Qv – k • A • T

T = (Ti - Ta)------------------------------------------------------------------------------------------------------------------------------------------------------Example: enclosure with area of 52 ft2 = 4.82 m2

Given: Painted Carbon SteelGiven: Painted Carbon SteelTa = 30°C (Maximum ambient temperature)Ti = 40°C (Maximum enclosure internal temperature)Heat load of components: 1000 W (Sum of All heat lossHeat 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 (Required cooling capacity)
