Frequency converters, especially in MCC panels used in this sector,
cause excessive temperature increases. Therefore, proper ventilation is
required to prevent the panels from overheating.
Temperature increase directly affects the performance of devices inside
the panel or rack cabinet. Temperature increase tests, which are as
important as short circuits in panel type tests, are critical for the
safe and efficient operation of devices. Since temperature increase
reduces the current carrying capacity, the temperature inside the
panel/rack cabinet must be brought to the ideal level with proper
ventilation.
The temperature inside the panel/rack cabinet increases due to the
ambient temperature and the heat emitting devices inside (breaker,
busbar, server, etc.). This temperature increase is calculated by taking
into account the electrical loss power values in the catalogs of each
device used.
The IP protection level also contributes to the temperature increase by
preventing the heat from escaping to the outside. Therefore, it is
important to choose the right IP level for the panel/rack cabinet, not
the highest one. A high IP protection level does not always mean better
protection, and the wrong choice can cause excessive temperature
increase and therefore damage to the devices.
After the temperature increase is determined, the panel or rack cabinet
can be cooled according to the value obtained by the following methods:
• Natural Ventilation
• Cooling with fan
• Cooling with Air Conditioning
