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.
