초록

Since the use of CFCs and HCFCs refrigerants are to be restricted due to the depletion of ozone layer, this experiment applies the R134a gas to study the performance characteristic from the superheat control for improving the energy efficiency. The experiments are carried out for the condensing pressure of refrigeration system from 1.5 MPa to 1.6 MPa by 0.05 MPa and for superheat temperature from 0$^{\circ}C$ to 5$^{\circ}C$ by 1$^{\circ}C$ at each condensing pressure. As a result of experiment, when the superheat temperature is 1$^{\circ}C$ at each condensing pressure, the refrigeration system has the highest performance.
