Structure

Graphic 3: Components of the compressor

Compressor

Electrical connection

Overheating protection OLP

The compressor (1) is integrated in the refrigeration circuit. The OLP (

ver

oad

rotector) overheating protection (2) and the electrical connections (3) are on the

top of the compressor.

3.4.2

Function

The compressor draws in the gaseous refrigerant and compresses it under high

pressure. During this process the refrigerant heats up considerably.
