Temperature conditions
Avoid hot
spots.
Final temperature Ts max
desired in the enclosure
is at least 5 °C higher
than the ambient temperature
Te max.
Final temperature Ts max
desired in the enclosure is
lower than the ambient
temperature Te max +5 °C.
Outside temperature is lower
than the lowest acceptable
ambient temperature
for the switchgear.
Risk of condensation.
Ts max ≥ Te max + 5 °C
Ts max ≥ Te max +5 °C
Need for a thermal system:
resistance heater

Solution
Install circulation
fans in the enclosure.
Oversize the enclosure
or the wall-mounting
enclosure.
Install ventilation louvers.
Install fans
for introducing fresh air.
Use an air-air
exchanger.
Use a cooling
unit.
Use an air-water
exchanger.
Heat using a
resistance heater.
Heat using a resistance
heater in order to
maintain the temperature
beyond the dew point
temperature.

Constraints
The amount of heat evacuated
is relatively low.
The amount of heat evacuated
is relatively low, larger dimensions.
The amount of heat evacuated
is low, it depends on the
layout of the components,
reduced IP (entry of dust).
Regular filter maintenance.
IP slightly reduced.
Regular filter maintenance.
Regular filter maintenance,
cannot be used beyond an
ambient temperature of 55 °C.
Needs a water circuit;
consumption if supplied
by the water mains.
