Descrição Geral

The Computer Controlled Basic Heat Exchangers Unit (TICC/SS) has been designed by Edibon to study and compare different types of small-scale heat exchangers working with parallel or counterflow arrangements.

The complete unit consists of two main elements: the service base unit and a heat exchanger.

The Basic Service Base Unit (TIUS/SS) is common for the optional "/SS" type heat exchangers. Its functions are:

  • Heating water in a computer controlled thermostatic bath.
  • Pumping the hot water.
  • Regulation and measurement of the cold water and hot water flows.
  • Measurement of the inlet and outlet temperatures of the cold water and the hot water.
  • Measurement of the pressure drop in the exchanger.

To supply cold water there are two options: tap water or our recommended element, the Refrigeration Water Recirculation Unit "TERA".

Other possibilities to be done with this Unit:

  1. Many students view results simultaneously. To view all results in real time in the classroom by means of a projector or an electronic whiteboard.
  2. Open Control, Multicontrol and Real Time Control. This unit allows intrinsically and/or extrinsically to change the span, gains, proportional, integral, derivative parameters, etc, in real time.
  3. The Computer Control System with SCADA and PID Control allow a real industrial simulation.
  4. This unit is totally safe as uses mechanical, electrical and electronic, and software safety devices.
  5. This unit can be used for doing applied research.
  6. This unit can be used for giving training courses to Industries even to other Technical Education Institutions.
  7. Control of the TICC/SS unit process through the control interface box without the computer.
