Computer Controlled Thermodynamic Cycle Of A Screw Compressor

Product Description

Computer Controlled Thermodynamic Cycle of a Screw Compressor

A Computer Controlled Thermodynamic Cycle of a Screw Compressor training plant for studying the energy transfer in a compressed air system.

The is controlled by a PC and software.

It includes industrial sensors and transducers.

The is designed to connect to the to expand the experimental capability.

The has been designed and manufactured to incorporate all current safety standards.

Experiments

• Analysing the pressure / volume diagram of the first and second stages of the compressor by experiment
• Determining the polytropic index
• Calculating the effective average pressure of the compressor

Checking the operation of the safety devices

• Using a T-s diagram for air to determine the characteristics of the thermal cycles by experiment
• For detailed study of the air characteristics it is necessary to connect the ACV85 to the ACV90 Compressed Air Dehumidification Training Plant
