Results of heat transfer and pressure drop investigation during flow boiling of R22, RI34a and R407C inside porous tube are presented. The experiments have been conducted for average saturation temperature 0°C, inlel vapour was set 0 and outlet 0.7. Mass flux density varied from about 250 to 650 kg/m²s. The stand and experimental procedure are described.
