What is a Piston Type Semi Hermetic Compressor?

This type of compressor features a semi-hermetic design that allows for easy maintenance while providing a sealed environment for the refrigerant. Unlike fully hermetic compressors, which are sealed permanently, semi hermetic units can be opened for servicing, making repairs and replacements more straightforward without compromising system integrity.

Key Components and Operation

At the heart of the piston type semi hermetic compressor is its reciprocating mechanism. The primary components include cylinders, pistons, and valves. Refrigerant enters through the suction valve, where it is then compressed by the piston moving within the cylinder. This process generates high pressure, allowing the refrigerant gas to exit through the discharge valve, entering the condenser.
