Advantages and disadvantages of high and low temperature test chamber refrigeration: reciprocating compressor also known as piston compressor. The working chamber of the compressor is the cylinder. The piston moves up and down in the cylinder, thus completing the processes of compression, steam exhaust, expansion and steam absorption.

I. advantages: it is widely used, with mature manufacturing technology, simple structure, low requirements for processing materials and processing technology, low cost, strong adaptability, can adapt to a wide range of pressure and cooling capacity requirements, and strong maintainability.

Two, disadvantages: can not achieve a higher speed, the machine is large and heavy, not easy to achieve lightweight, exhaust discontinuous, the air flow is prone to fluctuations, and there is a greater vibration when working. Due to the above characteristics of crankshaft connecting rod compressor, few small displacement compressors have adopted this kind of structure. At present, crankshaft connecting rod compressor is mostly used in large displacement air conditioning systems of buses and trucks.
