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
