Piston Compressor Behaviour:

Description of Piston Compressor Behaviour:

Smaller refrigeration systems usually have a Piston Compressor. Piston compressors are positive displacement machines. These differ in their characteristics decisively from flow equipment which include the turbo compressors that are common in very large systems. In Piston Compressorsthe flow rate is mainly dependent on the displaced volume and speed. Due to the unavoidable dead space the flow rate drops with increasing pressure ratio. Because the flow rate is a measure for the refrigeration capacity of the refrigeration system, the properties of the compressor are important for the capacity of the whole system.

Specification of Piston Compressor Behaviour:

1. Experimental unit for piston compressor from refrigeration
2. Open process with air
3. Typical open 2-cylinder compressor
4. Drive via asynchronous motor with frequency converter for speed adjustment
5. Inlet pressure and outlet pressure (pressure ratio) adjustable via valves
6. Instruments: 2 manometers, flow meter, sensors for pressure, temperature, speed, torque (via force), flow rate, digital power indication
