Description
NiYo Engineers’ Computer Operated Refrigeration Trainer is designed for the study of thermodynamics of vapour compression refrigeration cycle. Various concepts of the refrigeration cycle can be understood by experimentation and demonstration.
Refrigerant is compressed using a compressor. Type of compressor can be selected by the user and application, For example, hermetically sealed, semi-hermetic, open, reciprocating, scroll, rotary, etc. Condenser is air cooled. Evaporator is water cooled.
Depending on the training need one or more of the expansion devices can be selected for comparative studies. Expansion devices can be capillary, thermostatic expansion valve or electronic expansion valve.
The equipment has all the necessary sensors/transducers to measure the test parameters. The data is fed to the PC through a signal conditioning unit, interfacing and communication system. The results can be analysed in tabular as well as graphical form.
The software is Windows based menu driven and user-friendly.
System can be loaded from minimum to maximum capacity.
Capacity of the Trainer can be selected based on the training requirement.
