4.3 mm 세관내 R-22와 R-407C의 증발 열전달과 압력강하
Evaporation Heat Transfer and Pressure Drop of Mixture Refrigerant R-22 and R-407C in a Diameter of 4.3 mm
초록
The evaporation heat transfer coefficient and pressure drop of R-22 and R-407C in a small diameter copper tube were investigated experimentally. The main components of the refrigerant loop are a receiver, a compressor, a mass flow mete, a condense and a double pipe type evaporate (test section). The test section consists of a smooth copper tube of 4.3 mm inner diameter. The refrigerant mass fluxes were varied from 100 to
