PA Hilton R634 Refrigeration Cycle Demonstration Unit

The R634 bench-top refrigeration demonstration unit is specifically designed for teaching and demonstrating the principle of vapor-compression refrigeration and heat pump cycle. Lecturers can design practical assignments that allow students to use this unit to investigate the pressure-temperature relationship during evaporation and condensation.

This unit is run with ozone-friendly, non-toxic, low-pressure working fluids for safety. All components are fitted inside clear, visible glass cylinders for students to observe the transient change of evaporation and condensation. A digital temperature indicator and refrigerant flowmeter can be fitted to the unit to support the learning activity.
