Compressor variable vane control regards the ability to alter a turbine's fin geometries position ranging from open to closed positions. By mechanically and pneumatically actuating (controlling) these geometries power outputs can be operator managed.

Mechanical control system for an compressor?
A rotary vane pump uses positive displacement to propel liquids. The inner rotor is offset from the outer cavity which creates an eccentric motion. The vanes are moveable which creates the difference is pressure needed to move the liquid.
The most important is the compressor, but the compressor alone can not cool down the chiller so next in line is the condenser after that is some kind of liquid flow control, that can be a capillary tube or a expansion valve then the evaporator where the real cooling happen then there is the thermostat that control te temperature
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.

Some do.
Depending on the refrigerator, it's TYPICALLY a "rotary vane" compressor, but that's not always the case.
A reciprocating compressor is one in which a piston or diaphragm moves in a reciprocating motion. The compressor used in the AC system of a Saturn is NOT a reciprocating compressor. It is most likely a "rotary vane" compressor.
use rotating members to compress and increase the pressure of the air.
Mechanical control system for an compressor?
a control variable is a variable that needs to be controlled
There are not any similarities between a control and a variable. However, a Control Variable, is a variable.
You can control it that's why its called control variable.
A control variable is a variable that is held constant in a research analysis.
what is the difference between a variable and a control
This type of compressor uses a special drive to control The speed of the unit. Also, saves more energy than a fixed speed equivalent.
