Description Air conditioning is a cooling product for rack cabinets. This product is used to cool electronic equipment inside the rack that are sensitive to rising temperatures and must be completely isolated from the outside air. Therefore, it can be used for rack cabinets that produce high internal heat or located in places where the ambient temperature is high outside. This product has several different operating modes with high reliability and away from any complexity can start working immediately after turning on. By rotating the internal fan, hot air is absorbed from the top of the cabinet and by passing it through the evaporator blades, its heat is taken and cold air is blown into the environment inside the cabinet from the bottom of the cabinet. Therefore, by creating a continuous and continuous air cycle, the temperature inside the cabinet is reduced to reach the desired temperature point. This operation is repeated for the external fan and reduces the temperature of the heat exchange by absorbing the cold air outside the cabinet.
