Description
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 compressors the 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
Test stand for piston compressor from refrigeration
Open process with air
Typical open two-cylinder compressor
Control of the experimental plant using a PLC, operated by touch screen
Screen mirroring: possible to mirror the user interface on up to 10 end devices
Drive via asynchronous motor with frequency converter for speed adjustment
Inlet pressure and outlet pressure (pressure ratio) adjustable via valves
Instruments: flow meter, sensors for pressure, temperature, speed, torque (via force)

Learning objectives And experiments
Determine characteristic variables of a piston compressor during experiments
Determination of the volumetric efficiency at different intake pressures, pressure ratios and speeds
Determination of the isothermal compressor capacity
Measurement of the mechanical and electrical power consumption in dependence of the high/low pressure and pressure ratio
Determination of the mechanical efficiency and the overall efficiency
Retrieve information from digital networks
Use digital learning media, e. G. Web Based Training 
Use visualisation systems
