Explosion-proof Packaged AC
Introduction:
The explosion-proof packaged cabinet AC is applied in integrated cabinets. It is a type of air conditioning equipment that can operate in very humid environments. This equipment uses high-efficiency fans and has relatively high production costs.
It is a device that can regulate the temperature, relative humidity, and flow velocity of the air inside the electrical control cabinet. The difference between cabinet air conditioner and ordinary air conditioner lies in the structure, service objects, and usage environment. The service objects of explosion-proof cabinet air conditioners are mainly electrical and mechanical equipment.


Application:
â—† For Zone 1 and Zone 2 explosive gas environments;
â—† For Class IIA, IIB, and IIC explosive gas environments;
â—† For temperature groups T1 to T4.
â—† Suitable for explosive hazardous environments such as petroleum refining, chemical, battery storage, paint rooms, chemical, pharmaceutical, military and military facilities;
â—† Suitable for use in larger spaces.

The target of explosion-proof cabinet packaged air conditioners is electrical, electronic, or mechanical components, not humans. Therefore, their set temperature can be set very high, between 30 ℃ and 45 ℃, with a default temperature of 35 ℃. In addition, electrical components have no requirements for wind speed or noise. In fact, the larger air circulation inside the cabinet can reduce the local heat island phenomenon of electrical components and help with their heat dissipation. In addition, except for outdoor cabinets, the vast majority of other cabinets are installed indoors, and some production environments are relatively complex, with harsh conditions such as high temperature, high humidity, high dust, and even oil or corrosive gases. Especially high temperature and high dust phenomena are relatively common. The working environment temperature of cabinet air conditioners is usually above 42 ℃, with a maximum of 70-80 ℃, and they must meet the following level requirements: such as being able to work continuously for 24 hours, being more robust than civilian products, and having a wider range of voltage requirements. This also requires cabinet air conditioners to meet the reliability requirements for use in this complex environment.

Features:
★ The product surface adopts surface temperature limiting protection technology, comprehensive anti-static technology, and various safety protection technologies;
★ Wide voltage design, suitable for unstable power sources in the field, voltage: 220V/50Hz, 220V/60Hz, 110V/50Hz;
★ Explosion proof markings: ExdibmbIIBT4 Gb, ExdibmbIICT4 Gb.

The cold air flow is directed into the heating area inside the cabinet through a splitter, while creating positive pressure inside the cabinet, preventing external air from entering and effectively cooling and purifying the cabinet. Small and compact multifunctional electronic control systems, variable speed drive systems, servo systems, and programmable logic control systems are extremely sensitive to heat and pollution. Overheating causes the failure of these sensitive electronic and electrical components, false display in the digital display system, drift in the control system, and misoperation of the system to stop at a load lower than the rated load.
The result is a decrease in production efficiency due to frequent machine or production line shutdowns. Fans can only provide insufficient cooling effect and often bring dirty, humid, and corrosive air from the environment into the cabinet, causing damage to electrical equipment. Air conditioners are bulky, difficult to install, and require frequent maintenance, resulting in high operating costs. The vortex cooler has no loss of moving parts and only uses an internal vortex tube to convert compressed air into low-pressure, evenly distributed cold air inside the cabinet.
Electrical equipment usually generates heat due to the action of current during operation, and high temperature can affect the service life and reliability of electrical components, and cause premature aging of insulation devices or a decrease in insulation value, resulting in increased resistance and heat generation of some conductors, and ultimately burning out. Usually, electrical components are labeled with the highest operating temperature or different performance corresponding to different temperatures.
