Vapour-Compression Refrigeration Unit

Vapour-Compression Refrigeration Unit



The vapour-compression refrigeration system is the most common refrigeration system used today.
RA1 is a computer controlled vapour-compression refrigeration system with automatic recording of appropriate process variables using an integral USB interface device. This allows the student to gain a thorough understanding of the refrigeration process by changing the operation of different parts of the process and recording the response of the complete system.

The software includes a range of functions and capabilities designed to make the operation of the equipment and processing of the results more straightforward, and also to enhance student understanding of the subjects being covered. It includes:

– Diagrammatic representation of the equipment, complete with continuous real time display of the various sensor outputs and instantaneous Coefficient of Performance

– Automatic data logging of sensor values into spreadsheet format

– Allows operator control of compressor speed (motor speed), condenser cooling water flowrate (pump speed) and evaporator heating water flowrate (pump speed)

– Incorporates maximum and minimum temperature limits to protect the equipment against misuse

– Additional USB driver is included that allows the outputs to be read in other software programs such as Labview™.
