It is widely used in oil and gas extraction and transportation, energy refining, aerospace weapons, power electronics, fine chemicals, military units, warehousing and logistics, metallurgy and mining, transportation, food and medicine and other industries. It is suitable for the instrument control room, laboratory, measurement room, analysis room and other places where the hazardous area is designated as zone 1 or zone 2, where flammable and explosive gases and dust exist or may exist. The unit can refrigerate, dehumidify, heat, ventilate, and maintain indoor positive pressure (optional). The shell material can be SS304/SS316L, carbon steell sprayed with plastic.
The unit air conditioner unit is a professional design made by our company based on years of design experience in the past, absorbing advanced design concepts at home and abroad, and aiming at various complex working environments and places. There are many types and models, and the cooling capacity can reach up to 3000kW, which can meet the needs of refrigeration, heating and ventilation in various explosive and dangerousl gas environments. The product has high energy efficiency ratio, low noise, beautiful appearance and small size, simple installation and convenient maintenance.
Product features
The unit can start automatically when the power is received, realizing fully automatic unattended operation. In addition, dry contacts are reserved forl the unit, with TCP/IP communication, MODEBUS-RTU communication function, Profibus-dp communication and other communication modes, which can realize functions such as fire protection interlocking.
Adopting the standard design of industrial air conditioners, each unit has been strictly inspected before leaving the factory, so that the unit can operate stably and reliably for a long time in harsh environments.
Precise control: The microcomputer controller is used to automatically sense the load of the air conditioner, and adjust the capacity output of the corresponding module according to the automatic control theory, so as to achieve the best match between the cooling (heat) capacity of the unit and the load of the air conditioner, so as to minimize the operating cost.
According to the needs of customers, the unit can use Siemens and other brands of PLC, and the electrical components can use well-known brands such as Schneider. The human-computer interaction interface adopts LCD text controller or explosion-proof touch screen, which has functions such as parameter setting, fault query, status display, etc., making the control more humane, reliable and comprehensive.
Emerson and other well-known brand compressors with high efficiency, safety and reliability, strong liquid shock resistance and high oil return capacity. The heat exchanger adopts high-performance inner-threaded copper tubes and hydrophilic aluminum foil fins or copper foil fins, which are processed by advanced mechanical tube expansion technology to achieve the best heat exchange efficiency.
The casing of the unit is made of 304/316L stainless steel and carbon steel sprayed with plastic, which has strong corrosion resistance and is elegant in appearance; the frame structure design strengthens the mechanical properties of the unit, and is easy to disassemble and maintain. The inner wall of the panel is attached with high-quality sound insulation and thermal insulation rubber and plastic materials, which can minimize the loss of cooling capacity and effectively reduce the noise of the unit.
The unit adopts a multi-blade double-inlet centrifugal fan, and the impellers have undergone strict dynamic balance calibration, with low noise, small vibration, and a good performance curve to make the work more efficient. The fan motor adopts Nanyang explosion-proof and other well-known brand explosion-proof motors, with reliable explosion-proof performance and stable operation.
Explosion-proof axial flow fans have the characteristics of high mechanical efficiency, small vibration, low noise, corrosion resistance and long life, and are suitable for various harsh environmental conditions.
The externally balanced thermal expansion valve of international famous brands such as Danfoss is selected, with reliable quality, good working characteristics and strong adjustment ability, which can prevent the change of static superheat caused by load change. The refrigeration system has protection devices such as high and low pressure protection. When the compressor is running abnormally, it will give an emergency alarm and provide protection; the explosion-proof fan has a thermal overload protection relay, which can protect the fan in time when it is overloaded; Real-time monitoring of the wind system of the air conditioning unit.
