A scroll compressor (also called spiral compressor, scroll pump and scroll vacuum pump) is a device for compressing air or refrigerant. [1] It is used in air conditioning equipment, as an automobile supercharger (where it is known as a scroll-type supercharger ) and as a vacuum pump .
The scroll-type supercharger is a scroll compressor used as a positive displacement orbiting-spiral supercharger. It is a compromise between the more rugged rotating lobe, and the more efficient sliding vane type superchargers, and is considered to offer the highest potential in regard to efficiency, noise and pressure fluctuation.
An animation of the operation of a scroll-type supercharger. Air is confined between the two spirals and is compressed as it is forced towards the centre. In automotive application, the spirals would have far fewer turns. The G-Lader is a scroll-type supercharger used in various Volkswagen Passenger Cars models.
In air conditioning, an inverter compressor is a compressor that is operated with an inverter. In the hermetic type, it can either be a scroll or reciprocating compressor . This type of compressor uses a drive to control the compressor motor speed to modulate cooling capacity.
A scroll compressor, also known as scroll pump and scroll vacuum pump, ... Therefore, work-consuming devices such as pumps and compressors (work is negative) require ...
Principal view of the pumping action of a twin-screw pump with a six-lobe female screw and a five-lobe male screw. A compressor (as opposed to a pump) would be shaped the same way, except that the shape of the lobes would change along the length of the screw, so that the volume of the trapped pockets would get squeezed smaller as they get closer to the exhaust port.
Air compressor supplies air into a nail gun.. An air compressor is a machine that takes ambient air from the surroundings and discharges it at a higher pressure. It is an application of a gas compressor and a pneumatic device that converts mechanical power (from an electric motor, diesel or gasoline engine, etc.) into potential energy stored in compressed air, which has many uses.
Today, the scroll compressor is a dominant technology in the HVAC& ;R industry. In air conditioning systems it is very common to use a number of scroll expanders in parallel because it increases the load sharing mechanism and part-load performance. In scroll expanders, the moment at which discharge and suction take place is only a function ...
