At many locations worldwide, a temperature range of more
than 50 K (e.g. minimum temperature –15 °C and maximum
temperature +40 °C) has been measured in outdoor installa-
tions. When using equipment suitable for outdoor use, which
operates correctly at interior temperatures of up to +55 °C,
an air/air heat exchanger may be used for climate control
purposes. The air/air heat exchanger has hermetically sepa-
rated air circuits and uses the ambient air to cool the raised
interior temperature at the heat exchanger module. With
a correctly designed heat exchanger, this climate control
concept is capable of limiting temperatures inside the
enclosure which are 10 K higher than the ambient tempera-
ture. The application range of the installed components is
crucial when selecting the right climate control unit. If equip-
ment intended for indoor applications is used outdoors at
an ambient temperature of up to approximately +35 °C,
a compressor cooling unit must be used. Only cooling units
can achieve temperatures in the enclosure interior which are
lower than the ambient temperature.
