3. Operating Principle
STULZ conditioners are designed to cool electric cabinets with IP54 protection level and
they are suitable for the operation in industrial environments. Their use allows to eliminate
problems caused by high temperatures, dirt and humidity which are present in the
environment.
The unit, which is basically made up of a sealed cooling circuit where the refrigerant
circulates, is divided into two sections, hermetically separated from each other, where the
air in the environment and the air in the cabinet are treated without coming into contact
with each other.
The system operates as follows:
The compressor compresses the refrigerant gas bringing it to a high pressure and
temperature.
The hot gas, by going through the condenser, is cooled and liquefied thus releasing heat
to the air in the environment. Pushed through the capillary pipe, the liquid refrigerant loses
pressure, which makes it prone to evaporation. This takes place in the evaporator, where
the refrigerant absorbs the heat of the warm air from the cabinet, which is therefore cooled.
