NH3 냉동장치의 과열도에 관한 성능 특성 연구(III)－열교환기 타입별 비교－ = The Study on The Performance Characteristics due to the Degree of Superheat in NH3 RefrigerationSystem(III) －The Comparison of Heat Exchanger Types－

다국어 초록 (Multilingual Abstract)

Recently, production and use of freon substances are restrained due to depletion 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 is to find the optimal operating conditions by comparing the performance between the shell and tube type and shell and disk type heat exchangers using the ammonia refrigerant, and to verify the superiority of the shell and disk type heat exchanger that is not used in field of refrigeration and air conditioning. Finally, this study shows that the shell and disk type heat exchanger is applicable to the ammonia refrigeration system, and this system minimizes the refrigerant charge and installation space.
