Typical compression refrigeration system with piston compressor, thermostatic expansion valve, evaporator and condenser (each in the shape of a pipe coil)
Sight glass to monitor the aggregate state of the refrigerant
Fundamentals of refrigeration in a simplified model
2 water-filled tanks with thermometer to demonstrate the cooling and heating effect
Pressure switch to protect the compressor
2 manometers with temperature scale for the refrigerant show the values of the refrigerant on the high and low pressure sides.
