Chiller Units Training Plant

A Chiller Units Training Plant that is designed to study the operation of a chiller and its components. For example the thermostatic expansion valve and flow switch.

The is designed so students can study the operation and theory associated with chiller units and to study the use of an intermediate fluid for transporting thermal or refrigerating power from the production / storage site to the air conditioning plant.

Faults can be introduced using the Manual Fault Simulator or the Electronic Fault Simulator to allow the students to troubleshoot the faults and diagnose the actions required to set the plant back into the correct and efficient operating condition

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

The refrigerant used complies with anti-pollution legislation.

Experiment

• Plant start-up and system monitoring using the protection and safety devices incorporated into the pilot plant
• Studying the operation of a chiller
• Studying the operation of a thermostatic expansion valve
• ON-OFF control
• Analysing system behaviour and reactions with the variation of:
• Air flow rate at condenser
• Air flow rate at air to water heat exchanger

Plotting the cycle in a refrigerant pressure-enthalpy diagram

• Obtaining data readings and calculation of:
• Thermal exchange surfaces
• Thermostatic valve superheat (hunting)
• Heat balances for the evaporator, condenser and compressor
• Refrigerant mass flow
• Ideal and actual Energy Efficiency Ratio 
• Volumetric compression efficiency
• Heat balances on water circuit
• Troubleshooting the system and its components using Fault Simulators
