PENGARUH ALIRAN TURBULEN TERHADAP PERPINDAHAN KALOR KONVEKSI PADA KONDENSOR MESIN PENDINGIN KONVERSI UAP MENGGUNAKAN R410a DENGAN R32

Abstract

Forced convection turbulent flow in a pipe is a heat transfer phenomenon in which up to now is still being studied and developed to reveal the basic mechanisms actual symptoms. According to Kays and london has developed a correlation coefficient of convection and so also by There are two refrigerants used in this study is R410a which has physical properties that are fairly high pressure and flammable. While the R32 is a refrigerant which does not cause ozone depletion and have good properties, non-flammable, non-toxic and relatively stable. In the research that has been done to know the performance (COP) vapor compression cooling machine if using refrigerant R410 and R32 by varying the rotational speed condenser fan speed is 0.85 m / s, 1.6 m / s, 2.2 m / s, and 2.8 m / s
