![]() Compression chamber goes smaller with rotary movement and trapped. High efficiency scroll compressors have been also developed fitted with brushless DC motors and driven by inverters. Scroll compression principle Compressor sucks air through air inlet located at outer scroll. ![]() Two identical scrolls are paired together to form. A scroll is an involute spiral mounted on a flat plate. Their best feature is low noise operation and reduced vibrations. Scroll compressors use a simple compression concept based on the unique involute spiral shape of the scroll. The scroll compressor is a rotary positive-displacement machine used at present in small (5-35kW) air conditioning and heat pump units, and car air conditioning systems. They also have very high efficiency at the design compressor ratio, which however decreases at different working conditions. Capacity ranges are from 2 to more than 100 KW, and consequently their use is not spread in applications with low cooling capacity, where rotary and hermetic reciprocating compressors are preferred, and with very high cooling capacity, where screw and centrifugal compressors are preferred.Īdvantages of scroll compressors include smaller dimensions and lower weight than reciprocating compressors of the same capacity, even if higher than rotary compressors. Scroll compressors are widely used in home and commercial air-conditioning systems, in heat pumps and in air-conditioning systems for telephone applications and data centres. The fluid is compressed by rotation of the orbiting scroll around the fixed scroll until being discharged in the centre. This has several advantages over traditional compressors. Little began the development of a scroll-type compressor for refrigeration for the Trane Co. A scroll compressor, on the other hand, contains a moving scroll which creates the needed pressure. The scrolls are interleaved so as to be in contact with one another in various places and thus form a series of gradually thinner pockets of air towards the centre. A scroll compressor offered improved efficiency, with the added benefit of greater reliability, smoother operation, and lower noise. ![]() These scrolls move in a circular motion instead of upward and downward motion as piston action in a reciprocating compressor. ![]() Scroll compressors use two scrolls, one fixed and the other moving and coupled to the motor. A scroll compressor is a compressor that uses two or more spiral-shaped scroll pieces for the compression of the working fluid. ![]()
