Talk about the compression refrigeration device of the refrigeration device in the dust-free workshop


There are three main types of refrigeration equipment in the clean room, namely compression refrigeration equipment, absorption refrigeration equipment and steam jet refrigeration equipment. Today, Jiangsu Jincheng industrial air conditioner manufacturer will introduce to you the compression refrigeration device of the refrigeration device of the clean room.


The compression refrigeration equipment of the refrigeration equipment in the clean room includes three types: piston (reciprocating) type, centrifugal type and screw type.


The main equipment of a piston (reciprocating) compression refrigeration device is a piston refrigeration compressor, commonly used as working fluids ammonia (NH3), Freon-12, 22 (F-12, 22). This type of equipment is driven by electric motors, is easy to use, has a wide variety of products, and has a complete range of products, which can meet the requirements of various types of air conditioning and cooling, and is widely used. However, one-time investment is large, equipment costs are high, power consumption is large, and maintenance and management are more complicated.


The main equipment of a centrifugal compression refrigeration device is a centrifugal refrigeration compressor, and the commonly used working fluids are Freon-11, 113, 114 (F-11, 113, 114). This machine has the same principle as the piston refrigeration compressor, but it only has a rotary motion, which is smoother than the piston type, has less vibration, and has fewer parts. It is often combined with an evaporator and a condenser, and the equipment is compact and has a small footprint. The centrifugal refrigeration compressor has a large refrigeration capacity, so this type of equipment is only used when the air conditioner consumes a large amount of cold.


The main equipment of the screw compression refrigeration device is the screw refrigeration compressor, and the commonly used working fluids are Freon-12, 22, and ammonia (F-12, 22, R717). Compared with the piston type, the currently produced screw refrigeration compressor has a slightly lower efficiency, but due to its simple structure, small volume, high suction coefficient, low exhaust temperature, large single-stage compression ratio, and it is not sensitive to wet stroke. It has the advantages of small exhaust pulsation, few wearing parts, long column repair period, and stepless adjustment of cooling capacity. Therefore, it is widely used in various refrigeration devices. Generally, this machine has good technical and economic indicators when used in refrigeration devices within the capacity range of (120-800)x105kJ\h.


Jiangsu Jincheng Air Conditioning Engineering Co., Ltd. has been focusing on the design, development and production of industrial air conditioning equipment for many years. Its industrial refrigeration is widely used. The main products are: industrial air conditioning, chemical fiber industrial air conditioning, textile industrial air conditioning, chemical fiber industrial refrigeration, and dust-free workshop refrigeration , Ventilation ducts, cooling towers, refrigerators and other air conditioning units and accessories.


Jiangsu Jincheng is a rare conscience manufacturer in the industrial refrigeration industry. If you want to know more product information, please contact: Mr. Song 13705113637 Website: http://q045.cn/
