ET 508

Two-Stage Air Compressor Simulator

Technical Description

This benchtop unit allows variables that affect the process (such as capacity, dead space, flow rate and state of the intake air) to be adjusted from the panel. The simulator can model operating states up to the theoretical limits. The significance of the dead space and air re-expansion thus becomes clear. The model comprises a control panel and a data acquisition card with software.

Learning Objectives / Experiments

- Basic principles of the multistage compression
process
- Special features of a multistage compressor
- Thermodynamic state variables
- Depiction of a compression process on a T-s
diagram and on a p-V diagram
- Condensation in the intercooler and aftercooler
- On-off pressure control with hysteresis

Features

* Simulated compressor system with intermediate
cooling and aftercooling₁
* Processing of the measured data on a PC
