What's the difference between piston and screw refrigeration compressors?
Screw is the inside of the two screw operation, the piston is the air pump, screw high efficiency, easy maintenance. The piston is more trouble.
Screw machine efficiency is very low, in contrast, popular point is that the screw machine is very power hungry
Screw with high efficiency. Easy maintenance, liquid resistance, no valve slice and well received. But can it run at high pressure or piston, such as CO2 compressor?.
Screw refrigeration compressors and piston refrigeration compressors in the same way compressed gas, volumetric compressors are that, that is, they are compressed by volume changes in the gas. The difference is that the two compressors differ in the way they work.The screw compressor works by relying on a positive rotor and a negative rotor engaged in the movement of the rotor, and by means of the space surrounding the inner wall of the casing around the rotor. When the rotor rotates, a rotor tooth, tooth and the inner wall of the casing is "V" shape of a tooth space called the element volume, the volume changes periodically, and it will be along the rotor axis by the suction outlet side of lateral movement, the refrigerant gas inhalation and compressed to a certain pressure after discharge.
