Pool boiling experiment was conducted to investigate the effect of subcooling on boiling of R-113 using 25mm effective dia. flat surface copper heater. Pool boiling heat transfer measurements were taken for wide temperature range of 5 - 39o C subcooling and investigated thoroughly. Variation in value of wall superheat of incipience boiling, from 27 to 34o C and 7 to 11o C temperature excursion observed. Noticeable effect of subcooling on boiling heat transfer is observed. Degree of subcooling was maintained constant by regulating pressure and keeping constant fluid temperature for each test run. Tests were conducted by applying heat flux step by step and data were recorded at steady state condition for each step of heat flux. By using the high speed photography bubble behavior in different condition was recorded and visually analyzed.
