Frost Chill Cooling
Inside a Compressor
The operation of a compressor is fairly simple as the primary function is to compress refrigerant through the piston.
When the refrigerant enters the compressor through the Low Side, it enters the Piston cylinder and gets compressed. This causes the refrigerant to transform to High-Pressure at High Heat as it expells the refrigerant out of the High-Pressure pipe.
An important reminder is to know the difference between Low and High-Pressure pipes.
The purpose of oil in the compressor
The oil in the compressor allows cooling and lubrication of the piston and motor windings. Over time, this oil can become contaminated and can age the compressor rapidly.
It’s not recommended to ever replace the oil when it is contaminated as there is no telling how worn out the compressor is at any stage.
