Nowadays CFCs and HCFCs refrigerants are restricted because it cause depletion of ozone layer. Accordingly, this experiment apply the NH₃ gas and not CFCs and HCFCs for refrigerant to study the performance characteristic from the superheat control and improve the energy efficiency from the high performance. The condensing pressure of refrigeration system is increased from 14.5bar to 16bar by 0.5bar and superheat temperature is increased from 0℃ to 10℃ by 1℃ at each condensing pressure. As the result of experiment, when the superheat temperature is 1℃ at each condensing pressure, the refrigeration system has the high performance.

Nowadays CFCs and HCFCs refrigerants are restricted because it cause depletion of ozone layer. Accordingly, this experiment apply the ammonia gas and not CFCs and HCFCs for refrigerant to study the performance characteristic from the superheat control and improve the energy efficiency from the high performance. The condensing pressure of refrigeration system is increased from 15.0bar to 16bar by 0.5bar and superheat temperature is increased from 0℃ to 10℃ by 1℃ at each condensing pressure. As the result of experiment, when the superheat temperature is 0℃ at each condensing pressure, the refrigeration system has the high performance.
