· Refrigerated room with static evaporator
· Thermostat for controlling the room temperature
· Capillary tube
· On-off valves, sight glass, dehydrator filter
· Valve for plant vacuum, refrigerant charging and recovering
· Pipes connecting the various components painted with different colors
· Full set of instruments for data acquisition, including:
– flowmeter
– high and low pressure gauges
– 2electronic thermometers with Pt100 probes to be inserted into several test points along the hydraulic circuit
– digital multi meter
· Thermomagnetic – earth leakage control button
· Emergency button
· Power supply: 230V AC 50 Hz single-phase – 150 VA
· Refrigerant : R-600a/ R-134a

ON-OFF control: refrigerator thermostat
· Using the refrigerant pressure-enthalpy diagram as work and diagnosis tool: plotting the refrigeration cycle
· Data acquisition and calculation of:
– heat balances corresponding to evaporator, condenser, compressor
– refrigerant mass flow
– ideal and actual EER
– volumetric compression efficiency and its trend versus compression ratio
– condenser exchange surface
– heat transfer coefficient between air and refrigerant in the condenser
– heat losses through the room walls
