Compressors are available in many types and designs from many well known and popular brands around the world. This is an important part of the refrigeration system and should be carefully selected so that the system can be effective in the workplace. Here are the most popular compressors on the market today.
Compressors and compressor functions
The refrigeration compressor is a mechanical device that compresses the refrigerant at low pressure to high pressure and high temperature and removes the vapors from the system to cool the system.
At present, most refrigeration, air conditioning and storage systems require compressors. However, the choice of machine depends on many factors.
Compressors
Screw compressors
Screw compressors use a pair of screw or rotor joints that together compress the refrigerant that is introduced between them. Compression by this method can produce high pressures with a small amount of media and consume less energy than piston compressors.
Screw compressor investment costs and maintenance costs are average or low in compressors. However, the screw compressor is difficult to operate in polluted operating environments, high rotational speed and lower life expectancy than other designs.
Piston compressor
Piston compressors use pistons and cylinders to produce compressive forces similar to internal combustion engines or piston pumps. The reciprocating motion of the piston is based on the external compression of the refrigerant inside the cylinder.
Piston compressors have low initial investment costs. The installation design is quite simple and fast. The output power of the machine is large and can reach high pressure. But the cost of maintenance is usually quite high, the machine operation is often very shaky. At the same time, pistons are not designed to run continuously at full load.
Spiral compressors
Spiral compressors use two interlocking screws to compress the refrigerant. One fixed disk, the other disk moves in orbit.
The smooth running compressor does not produce the highest noise and performance in compressors. Flexible liquid handling can be achieved. However, in the closed machine, the repair is quite difficult and they can not operate in two dimensions. Spiral compressors are mainly used in commercial air conditioning and refrigeration systems.
Spindle compressors
Spindle rotary presses use two rotary joints as gears to compress the refrigerant. The suction and compression are done simultaneously
The equipment has very few moving parts, low rotational speed, low initial cost and maintenance and good adaptation to dirty environment. The major drawback of this machine is the lower refrigerant flow and lower pressure than other types of compressors.
Centrifugal compressor
Centrifugal compressors operate on the fixed displacement of the chamber rather than on the principle of volume as other compressors. When rotating propeller operation forces the center of gravity onto the refrigerant inside the compression chamber.
The compressor is suitable for high volume and low pressure fluid pressures. Compressors have a simple design, less moving parts and energy efficiency when operating in multi-level mode.
In addition to the structure and operating principle, the compressor is also divided into groups based on the degree of seal of the machine.
Sealed machines are engine parts that are mounted inside a sealed steel enclosure. Semi-closed motor compressors are mounted in the compressor housing and are joined together by a flange and fixed by bolts. The open compressor will have a separate engine to run the machine.
Compressed air compressors are better able to protect the equipment, but at the same time it is difficult to unload the machine for adjustment and repair. This is the opposite of open compressors. Compressors allow easier adjustment and repair of equipment, but parts without protection.
