Recirculating Air Conditioning Unit

Lab Catalog Supply Code: EEZ0013


Recirculating Air Conditioning Unit Specification:


  • Comprehensive Air Conditioning teaching system, complete with initial heating stage, humidifier, chiller/dehumidifier, final heating stage, climatic chamber with window, return duct and adjustable recirculation.
  • Transparent conditioning duct (200mm x 200 mm) for complete visibility of the process
  • Computer controlled via USB interface, with complete educational software including data logging, graph plotting with real time updates, mimic diagrams, data export
  • Educational software, replicating the psychrometric chart calculations
  • Six sets of Temperature and Relative Humidity measurements at the various stages of the process
  • RH sensors come with calibration values which can be entered into the software for best accuracy
  • Electronic flowmeters (2) measure the flow in each duct
  • Measurement of refrigerant pressures, temperatures and flow
  • Dual control of boiler setting with a fast heat up setting and a gentle setting for control
Features:
  • Transparent Duct for full visibility of the process and the components
  • Includes pre-heaters, humidifier, chiller/dehumidifier and reheaters
  • Fully instrumented, with temperature and Relative Humidity sensors at every stage of the process, plus an air flow sensor.
  • RH sensors calibrated for maximum accuracy.
  • Suitable for both vocational training and for rigorous academic analysis of the thermodynamic principles involved
  • Fully computer controlled with real time data logging of results.
  • Capability of using PID control for preheat, humidity and reheat allows stable conditions to be set up for investigations.
