Understanding Hermetic Compressors

Introduction to Hermetic Compressors

• The presenters are students of mechatronics from the Instituto Tecnológico Superior de Coaxaqualcos, introducing the components of a hermetic compressor found in refrigerators and air conditioning systems.

Types of Compressors

• This hermetic compressor is categorized under positive displacement compressors, specifically reciprocating or alternative types that utilize a piston for gas compression and pumping.

Initial Inspection and Testing

• To test the compressor directly, three connections must be identified using a multimeter set to ohms. Measurements will help identify the start winding, run winding, and common connection.

• Only one pair of connections showed resistance; the other two combinations indicated an open circuit.

Internal Inspection Findings

• An internal inspection revealed a cut connection within the compressor. The unit has three connections for refrigerant flow.

• Oil was extracted from one connection; this oil is crucial for lubricating compressor parts through splash lubrication but can cause blockages if mixed with refrigerant.

Compressor Mechanics

• The animation illustrates various parts of the compressor. The oil is stored in the crankcase, providing lubrication during each movement of the mechanism.
