A bench mounted vapour compression Refrigeration Cycle Demonstration Unit using a hermetic compressor and water cooled flooded glass condenser and evaporator. Internal electrical and mechanical safety devices allow for unsupervised operation by students. Standard instrumentation fitted enables measurement of the condenser and evaporator pressures and temperatures as well as water flow rates and water temperatures. A float controlled expansion device controls the flow of refrigerant in the system. Refrigeration Cycle Demonstration Unit operates on low-pressure non-toxic ozone friendly refrigerant.
Experimental Capabilities:
Investigation and demonstration of the pressure-temperature relationship during evaporation and condensation.
Demonstration of the vapour compression refrigeration and heat pump cycle with visual observation of all-important processes.
Demonstration of: -
Determination of effect of evaporating and condensing temperatures on the refrigeration rate and condenser heat output.
Determination of overall heat transfer coefficient in a simple shell and tube type heat exchanger.
Investigation of the effect of compressor pressure ratio on system performance.

The unit allows to study the buckling of pieces of different lengths, ranging from 300 mm. to 625 mm, to which different support conditions can be applied:
Rigidly fixed end conditions.
Pin-joined end conditions.
One end pinned and the other fixed.
To measure the compression force exerted on the structure, there is a system composed of an elastic ring whose deformation is measured.
The compression force will be directly proportional to the deformation registered in a dial gauge.
To carry out the practical exercises correctly, it is very important to apply the force with an only axial component. For that purpose, the unit has a differential screw placed at one end, which allows the system compression.

The pressure profile is indicated by the different heights reached by the lubricant in the tubes. The unit is intended for use with the basic module 13 measuring points that open out into measuring tubes are distributed around the periphery of the bearing shell. The unit enables the pressure distribution in a plain bearing with hydrodynamic lubrication to be displayed. Due to the radially adjustable bearing housing, the width of the gap can be adjusted in 1/100mm steps using a micrometer.

A rigid enclosure with acoustic lining may be placed over either noise source and attachments allow investigation of sound attenuation in ducts.
Each of two microphones may be connected to a DBA Filter and illuminated bar display to show relative loudness.
A self-contained unit for the demonstration of the methods of noise and vibration control. Variable control of both voltage sources allows speed control of both motors. An integral 240v electric motor and gearbox together with a 12v fan unit provide two noise sources.
Resilient mountings and mount bypass equipment allows investigation of modes of vibration at various frequencies and transmission of noise through solids.

The programme of exercises enables familiarisation with six different drive implementation and analysis methods: understanding the brief and the drawing, assembly, setting, adjusting, testing, and making calculations. This laboratory system is used to introduce combined drives and their correct assembly. A robust tubular steel frame with a square profile and bearing elements provide the accuracy for the setting of precise gearing. The flexibility of the set-up and the modularity of the components simplifies experimentation and implementation of the students' own ideas. All the system components are kept ready to hand and well protected in a housing system.
