PC Operated Interacting, Non-Interacting System Trainer

Description

NiYo Engineers’ PC Operated Non-Interacting System Trainer is an ideal training equipment to study process dynamics. An arrangement of three tanks can be configured as Single Tank System, Two Tank Interacting System or Two Tank Interacting System. Dynamic response of Step change and Impulse change can be measured..

A specially designed flow system ensures a constant flow rate that can be varied as per the need. To note level in two tanks and flow simultaneously, at an interval of 5 seconds is difficult to achieve. Add to this the task of applying disturbance. Our PC operated system comes to rescue here. You can set interval at which you want to log the data. You can remotely apply a disturbance of step change or impulse to steady state condition. Software calculates all the parameters and displays observed data along with predicted data. The data can be viewed in tabular as well as graphical form.

Components

  • Circular tanks, 3.5 lit
  • Sump tank
  • Constant flow generation system
  • Level transmitters
  • Flow sensor transmitter
  • Piping
  • Interface and data acquisition hardware
  • Windows based software
  • Computer
  • Compressor

PLC Controlled and Computer Interface Refrigeration Training System

Description

NiYo Engineers’ PLC Controlled Refrigeration Training System is the latest state of the art training system in refrigeration and air conditioning (HVAC). Temperature, pressure power input to the compressor, etc can be measured for better understanding of refrigeration cycle. He equipment can be operated in one of the four different modes,

  1. Normal mode
  2. Electrical wiring mode
  3. PLC Control mode
  4. Computerised mode

In normal mode the training system operates manually like any other refrigeration training system.

There is a facility to get hands-on experience in basic electrical wiring of a refrigeration system. In this mode, trainees can do the wiring of various systems that is usually found in commercial refrigeration system. After completing the wiring, it can be operated and tested for better understanding.

The refrigeration system can be interfaced with the PLC and controlled by the PLC. Trainees can write various PLC program, test it in the stand-alone mode before taking it on-line in the refrigeration system.

The training system is interfaced with PC. The software shows the real-time data like temperature, pressure, power consumption, etc. There is a data logging facility. The software calculates COP and plots the cycle on pressure-enthalpy (p-h) chart
