영문 초록

The purpose of this project is to find the best alternative refrigerants by analyzing the temperature and pressure distributions of 4 kinds of refrigerants in Copper tube. Four refrigerants are commonly used CFC-12 and three alternatives which are HCFC-22, HFC-134a and HFC-152a. The pressure and temperature variations along flow direction in tube are numerically analyzed by a commercial thermalfluid code, PHOENICS. The results say that HFC-134a has the smallest pressure drop along flow direction among four refrigerents and that CFC-12 shows the largest temperature decrease as it flows in tube but HFC-134a also has very same trend of temperature variation with CFC-12 and so HFC-134a is the best alternative, while considering the variations of pressure and temperature.
