Compression Systems
Provides a Solid Understanding of Compression Systems in HVAC Equipment

This module includes detailed information on compression ratio and volumetric efficiency. Practical examples and solutions are included to help the reader understand why some systems are more efficient than others. The discharge and suction strokes of reciprocating compressors and how they relate to compression ratio and volumetric efficiency are explained.

Also covered in this module are;

• System flooding
• Migration
• Slugging
• Automatic pump-down systems—with electrical circuit analysis
• Crankcase heaters
• Suction line accumulators
• Oil separators

Compressor performance curves and graphs, compressor specifications, parallel compressors and their oil systems are also explained in detail. Voltage variation is explained as it applies to compressors.

A solid understanding of the compression system is necessary to successfully perform field service.
