In a scroll compressor refrigerant is compressed by two offset spiral disks that are nested together.
The upper disk is stationary while the lower disk moves in orbital fashion. The orbiting action of the lower disk inside the stationary disk creates sealed spaces of varying volume.
Refrigerant is sucked in through inlet ports at the perimeter of the scroll. A quantity of refrigerant becomes trapped in one of the sealed spaces. As the disk orbits the enclosed space containing the refrigerant is transferred toward the centre of the disk and its volume decreases.
As the volume decreases, the refrigerant is compressed. The compressed refrigerant is discharged through a port at the centre of the upper disk.

Does an Air conditioning scroll compressor work for an expander?
yes
Why is a scroll compressor more efficient than a reciprocating compressor?
The scroll compressor is one that has spirals rotating into each other. The screw compressor is where two spirals are rotating in opposite directions.
What is the difference between Digital Scroll Compressor and Inverter scroll compressor?
In digital scroll compressors, the motor runs continuously at full speed, and the capacity of the compressor is adjusted by a digitally controlled mechanical unloader (slide bar) which adjusts the vertical positioning of the orbital scroll with respect to the fixed scroll thereby reducing its capacity. In inverter scroll compressors, the relative positions of the scrolls does not change, but the speed of the motor is adjusted by a variable speed drive, which adjusts the capacity. The inverter scroll compressor is more energy efficient at part load conditions than a comparable digital scroll compressor. The digital scroll compressor will more closely match a specified load, but is not as energy efficient as a comparable inverter driven compressor. Both types of compressors have associated built-in mechanisms to maintain compressor lubrication at low flow.
What type of compressor trap the gas for compression?
scroll type compressor
What are the parts of refrigeration compressor?
The parts of a hermetic (sealed) reciprocating compressor is as follows; motor, crankshaft, bearings, valves, and pressure relief valve and piston(s). there are other smaller parts that can be named but these are the main players. The hermetic scroll compressor is a little different than the reciprocating compressor because it uses an orbiting scroll and a stationary scroll to compress the refrigerant instead of pistons. This is why a scroll compressor cannot run "backwards". The scroll compressor also has an oil pick up tube which differs from a reciprocating compressor. Now a "semi-hermetic" compressor is build like a small engine. It has an oil pump, reed valve plate, unloaders, pistons, bearings, etc. A screw compressor is in a class all to itself.
What is the Average warranty for a home air conditioning compressor?
If its a copeland scroll compressor it should be Life time..
What kind of compressor pumps are available from Compressor World?
There are many types of compressor pumps that are available from Compressor World. Examples of compressor pumps that are available from Compressor World includes scroll compressors and air compressors.
What is the life expectancy of a scroll compressor?
in residential air conditioning about 15 years
What is name of compressor used in domestic refrigerators?
Most of them are hermetically sealed scroll compressors
What is the material?
acummulator can we use filter dryer. we have about 20 scroll compressor already damage the orbiting and fix scroll vane, we want to know what action to be done.
How do you tell if you have a scroll or rotary compressor?
the shape or call the parts house with model number and make
How Does Heating From A Heat Pump Work?
The heart of the heat pump is the Copeland scroll compressor. The compressor continuously pumps the ozone safe refrigerant from the outside coils to the inside coils. The refrigerant carries the heat with it to be released inside the house. Then the warm air is circulated throughout the home by the furnace fan. In the summer the flow of the refrigerant reverses and the house is cooled in the same way. The scroll compressors are extremely reliable and virtually trouble free. Copeland is the largest manufacturer of heat pump compressors in the United States. Our Goodman heat pumps are built to last with reliable Copeland scroll compressors. Scroll compressors are very durable because they have fewer parts than the older reciprocating compressors and are also simpler in construction. Instead of pistons and valves which the older compressors had, the scroll compressor has a scroll that orbits to compress the refrigerant.
