| Abstract |
Recently, production and use of Freon substances are restrained due to destruc-tion of ozone layer and grobal warming. In this aspect of environmental problems, the best solution is to use the natural refrigerant such as ammonia. Thus, this study apply the NH3 and R22 to study the performance characteristic from the superheat control and compare the energy efficiency of two refrigerants from the high performance. The condensing pressure of refrigeration system is increased from 1,500kPa to 1,600kPa and degree of superheat is in-creased from 0 to 10℃ at each condensing pressure. As the result of experiment, when com-paring the each COP, we knew the NH₃is suitable as the alternative refrigerant of the R22. |
