The unit is with reliable performance, compact structure, convenient operation, and beautiful appearance. It is widely used in oil and gas extraction and transportation, energy refining, aerospace weapons, power electronics, fine chemicals, military industrial units, warehousing and logistics, metallurgical mines, transportation, food and medicine. Inflammable and explosive gas and dust instrument control room, laboratory, measurement room, analysis room and other places where the hazardous area is designated as zone 1 and zone 2, with refrigeration, dehumidification, heating, ventilation, and maintaining indoor positive pressure (Optional) and other functions, the shell material is SS304/SS316L carbon steel sprayed.
Marine air-conditioning units are professionally designed by our company based on years of experience in explosion-proof air-l conditioning design, absorbing advanced design concepts at home and abroad, and aiming at the characteristics of various complex working environments and places. Refrigeration, heating and ventilation needs of explosive hazardous gas environment. The product has high energy efficiency ratio, low noise, beautiful appearance and small size, simple installation and convenient maintenance.
With auto start function, which can realize fully automatic unattended operation. Dry contacts are reserved for the unit, which canl realize functions such as fire protection interlock. With TCP/IP communication, MODEBUS-RTU communication function, PROFIBUS-l DP communication and other communication modes.
Industrialized design air conditioners, and 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 capacityl 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.
Unit can use Siemens and other brands of PLC upon request, and the electrical components can use well-known brands such asl 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 are used, 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,l which are processed by advanced mechanical tube expansion technology to achieve the best heat exchange efficiency.
Housing option: 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. l 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, withl low noise, small vibration, and a good performance curve to make the work more efficient. The fan motor adopts a well-known brand motor with reliable performance and stable operation.
Marine 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. l it will give an emergency alarm and provide protection; the explosion-proof fan has a thermal overload protection relay, which canl protect the fan in time when it is overloaded; Real-time monitoring of the wind system of the air conditioning unit.
