What is a scroll compressor?
Scroll Compresor is used in air -conditioning and cooling systems to compress refrigerant gas for cooling. The design of the scroll system has existed since the beginning of the 20th century, but the techniques of accurate machining did not support commercial development only in the 1970s. The scroll consists of two spiral sections, one stationary and one that orbits in a circle and creates a compression effect needed for cooling.
Cooling systems require that the compressor function properly, because the refrigerant gas needs to be compressed and then expand to reduce the gas pressure. This pressure drop in combination with a change in refrigerant from liquid to steam reduces the temperature of the circulating inside metal coils and provides cooling. The low -pressure gas then returns to the compressor and the cycle is repeated until the desired temperature is reached.
The compressor design consists of two parts of a scroll or spiral, one welded to the compressar body and the other connected to the electric motor. When the engine triggers, moving the scroll is aboutIt turns orbital movement that could be described as the movement of marble inside the pelvis. Movement is rather circular than moving back and forth, which is found in reciprocal compressors.
As a scroll around the stationary part, pockets of refrigerant are captured between two scroll parts. The gas gas entry is the Svička on the outside of the widest part of the scroll and the high -pressure output is in the center. The trapped gas moves around the coil spiral and moves to a growing small area, resulting in higher pressure. When the gas reaches the center of the scroll unit, it is at the desired drain pressure and leaves the compressor.
Scroll Compresor can be very durable because there are few moving parts and the unit is not subject to some kind of SSOR composition. If a liquid refrigerant enters, the reciprocal compressors can be damaged by pistons because the liquid does not celebrate and may damage or even destroyPresor. The scroll accepts some liquid, because the section moving with a scroll is not locked against the stationary part and can move slightly if the liquid enters. The effect of the liquid on the compressor is called "liquid sliding" and the compressor shifting is a good choice if it is likely to be likely.
Reciprocation compressors use pistons and cylinders, similar to automotive engine, to compress refrigerant gas. The pistons have rings that seal the walls of the cylinder and allow gas pressure to climb. Once the rings and cylinders are worn, the gas can bypass the pistons, resulting in a lower compressor and a possible failure of the compressor. Scoll Compressor is sealed with two scroll members sliding against each other and maintaining compression with a smaller gas or gas. The efficiency of compression can increase over time as sliding the compressor surfaces will polish and improves the ability to seal.
Most compressors must be installed in a specific orientation, either upright for most reciprocal compressors or hipsfor screw compressors. Since the end of the 20th century, manufacturers have selected to provide scrolling compressors that can be mounted in or on their side, allowing flexibility in the customer's equipment. The surrounding movement of scrolls also leads to lower vibrations, which can make them an advantage in applications where noise or vibration needs to be controlled.
