Aimed at source below 200 ℃

organic refrigeration R600a was selected as the working fliud

and the system was built by organic medium R600a and plate evaporator. The paper firstly theoretical analysis the steady state mathematical of plate evaporator

which provides the necessary theoretical foundation for the experiment and data analysis. In the experiment

the different value of overheat was measured when the system changes the flow rate of the R600a refrigerants

and the paper finally confirms the basic transfer function relationship of the type evaporator and the overheat.
