What is a Screw Compressor?
The compressor is one of the main components of air conditioning systems in the refrigeration cycle. As we have mentioned in different sections, the refrigeration process consists of four main components, which include the compressor, condenser, expansion valve, and opera.
tour is done. The purpose of the compressor in the refrigeration cycle is to convert liquid into gas or vapor, and this process occurs on the refrigerant.
How to operate and process the activity of the screw compressor
If we want to define the screw compressor in a simple way, in general, this system has two spiral rotors, male and female. One of these rotors is connected to the main engine and the other one moves with the rotation of the main rotor. Therefore, after passing through the rotors, the refrigerant turns into high pressure steam.
In general, the operation process of the screw compressor includes four stages, in the first stage of the screw compressor, according to the suction part on which it is designed, the refrigerant enters the device. In the second stage, the moving rotors lead to the compression of the refrigerant by reducing the distance between the grooves along the length of the compressor, the process of the compressor continues until the movement of the rotors approaches the discharge point of the compressor, which is usually the pressure of the refrigerant in This part is very large, and in the last step, the compressed refrigerant vapor is released from the intended outlet.
5 Important Features of Screw Compressor
The screw compressor has the following features:
Absence of fluctuations when the working pressure is very high
Screw compressors have lower repair and maintenance costs than piston compressors and usually the parts involved are also less.
The third feature that can be mentioned for screw compressors is their volume and high capacity.
Another feature of screw compressors is their small volume compared to other similar models.
Screw compressors have less vibration
The benefits of the screw compressor that should be considered !!
Compressors have various advantages and disadvantages, among the advantages of screw compressors, we can mention 25-30% energy savings compared to piston compressors, and screw compressors usually transfer the refrigerant flow. They are completely uniform and also create less space and noise. The types of parts used in the screw compressor are static and therefore have lower depreciation. Capacity control in screw compressors is linear, and it is also possible to control the temperature of the output refrigerant by injecting oil into them.
