Functions of a Refrigeration Compressor | Hunker A refrigerator compressor is the center of the refrigeration cycle. It works as a pump to control the circulation of the refrigerant, and it adds pressure to the refrigerant, heating it up. The compressor also draws vapor away from the evaporator to maintain a lower pressure and lower temperature before sending it to the condenser.

Refrigeration Basics - Basics Part 2 There are 4 main components in a mechanical refrigeration system. Any components beyond these basic 4 are called accessories. The compressor is a vapour compression pump which uses pistons or some other method to compress the refrigerant gas and send it on it's way to the condenser.
REFRIGERATION COMPRESSOR OPERATION, DATA & MAINTENANCE MANUAL • Should the compressor be stopped due to uncharacteristic indications, investigate and repair the problem prior to restarting the compressor. • Do not operate the compressor beyond the design specifications and limits. • Remain at a safe distance from the compressor driving system when the compressor is operational
Refrigerating Compressor | Article about Refrigerating ... One of the most important characteristics of a refrigerating compressor is the refrigerating capacity of the refrigerating system, which, for a given refrigerant and under given temperature conditions, is proportional to the volumetric refrigerating capacity.
Vapor-compression refrigeration - Wikipedia Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air-conditioning of buildings and automobiles. It is also used in domestic and commercial refrigerators, large-scale warehouses for ...
Function of Reciprocating compressors in a refrigeration circuit The basic components of any refrigeration system (Figure 11.1) working on the vapour compression cycle, are the compressor, condenser, expansion valve, evaporator and the refrigerant fluid which is alternately vaporized and liquefied during the refrigeration cycle.
What Is the Function of a Compressor in an HVAC System? | Hunker The compressor is the heart of the cooling function of heating, ventilation and air conditioning (HVAC) systems.
