초록

몬트리올 의정서에 의해서 규제 받는 CFCs와 Halon의 대체 물질인 HFC-23, HFC-125, HFC-227ea, HFC-236fa와 불활성 화합물 $Ar, N_2, CO_2$의 열역학적 물성인 포화압력, 밀도, 엔탈피, 점도를 비교하였다. 본 연구에서는 소화제의 물성을 문헌 값을 온도의 함수로서 표시하였다. HFC 화합물의 열역학적 물성은 Halon-1301과 비슷하게 나타내었다. 불활성 화합물은 주로 혼합물로 이용되지만, 불활성 화합물의 물성은 Halon-1301에 비하여 바람직하지 않았다.

For CFCs and Halons regulated by Montreal Protocol and their alternatives of HFC-23, HFC-125 HFC-227ea, HFC-236fa and the mixtures of inert gases of $Ar, N_2 and CO_2$, the thermodynamic properties of saturated pressure, density, enthalpy and viscosity were compared. In this study, the data from literature were expressed as a function of temperature. Thermodynamic properties of HFC compounds were similar to those of Halon-1301. Inert gas was mainly used as a mixture, but the physical properties of the inert gas does not have the favorable advantages over those of Halon-1301.
