This training set has been prepared to show the basic features of the mechanical compression refrigeration cycle,and the evaporation process of the refrigerant in the transparent evaporator can be observed with different nano-fluids in the system.

The training set is designed to teach the basic refrigeration cycle and its elements.Basic elements such as condenser,evaporator,expansion valve,compressor,capillary tube,filter dryer are introduced and their functios are explained.The PH diagram of the R-134a gas is used as the pressure-enthalpy diagram.
