摘要：

Heat　transfer　coefficients　in　nucleate　pool　boiling　for　refrigerants　under　saturated　conditions　at　0.9　MPa　were　measured　on　a　horizontal　copper　surface.　Those　refrigerants　were　the　pure　components　of　HFC-134a,　HFC-32,　HFC-125　and　two　kinds　of　binary　mixtures:　nonazeotrope　mixture　HFC-32/134a,　azeotrope　mixture　HFC-32/125　compared　to　pure　components,　both　binary　mixtures　showed　lower　heat　transfer　coefficients.　This　deterioration　was　more　pronounced　as　heat　flux　was　increased.　Experimental　data　were　compared　with　some　empirical　and　semi-empirical　correlations　available　in　literature.　For　binary　mixtures,　the　accuracy　of　those　correlations　varied　considerably　with　mixtures　and　heat　flux.　©　2007　Elsevier　Ltd.　All　rights　reserved.
