Specifications

1. The Air Conditioning Laboratory Unit is designed to demonstrate the working principles of air conditioning system.
2. All measurements a read manually and through computer linked software.
3. Air-cooling is provided by vapor compression refrigeration system with pressure, temperature and refrigerant flow measurement.
4. It should allow the construction of a full cycle diagram and the balancing of refrigerant system energy balance against the airside energy transfer.
5. The base unit comprises a variable speed radial acting axial flow fan discharging into a 250mm square duct with steam humidifier, electrical pre-heaters, direct expansion cooling coil/de-humidifier, electrical re-heaters and orifice plate for airflow measurement.
6. It should allow the construction of a full cycle diagram and the balancing of refrigerant system energy balance against the airside energy transfer.
7. Instrumentation allows the electrical power to each resistive load to be measured and balanced against the air enthalpy change and mass flow.
8. A complete instrumented air conditioning laboratory unit mounted on a frame and castor wheels.
