Reciprocating compressors, or piston compressors, divided into hermetic, semi-hermetic and open, are used above all for applications with very high cooling capacity requirements.In the past these were also used in applications with very low cooling capacities due to their low costs, however they’ve progressively been replaced by rotary compressors. These compressors are extensively used in air conditioning and refrigeration because they are lighter, smaller and have fewer moving parts than reciprocating compressors and they are also more reliable. So, it contains all the compressor rotating components. These Compressors are characterized by high efficiency, durability and … All these actions are in sequence. The reciprocating compressor is similar to an automobile engine. When moving from BDC to the TDC position, the piston does not touch the cylinder at the top position, rather some volume is remains vacant between the top position of the piston and the cylinder, this volume is called as the clearance volume. A refrigerator compressor is the center of the refrigeration cycle. The refrigerant from the suction pipeline is taken inside the cylinder of the compressor via the suction valve. The rotary motion of the crankshaft is converted into the reciprocating motion of the piston inside the cylinder via the connecting rod.
