Compressors

Compressors: What do they do?

The compressor is the heart of the A/C System. Its primary function is to:

• Pump refrigerant and oil through the system
• Generate suction & discharge pressure

TECH TIP: Putting a larger displacement compressor on a vehicle rarely makes it perform better and in some cases it can actually decrease performance. Most systems are designed for specific goals. These goals are determined by a number of factors: glass area, interior space, projected heat load, engine operating RPM, just to name a few. After all these factors have been calculated, the heat exchangers are designed for a specific BTU range. The compressor is then selected for the application.
