Specification

[1] fundamentals of refrigeration in a simplified model

[2] typical compression refrigeration system with piston compressor, thermostatic expansion valve, evaporator and condenser (each in the shape of a pipe coil)

[3] 2 manometers with temperature scale for the refrigerant show the values of the refrigerant on the high and low pressure sides

[4] 2 water-filled tanks with thermometer to demonstrate the cooling and heating effect

[5] pressure switch to protect the compressor

[6] sight glass to monitor the aggregate state of the refrigerant

[7] refrigerant R134a, CFC-free
