  • To probe into the refrigeration performance of hole finned-tube under frosting,a wind-tunnel experiment research on the energy conservation performance was carried out when air flows over a single-row-plane finned-tube refrigeration exchanger under a frosting condition. The experimental results show that compared with a plane finned-tube refrigeration exchanger in the same experimental condition and geometric size,when the average face velocity is from 1.87 to 5.0 m/s,the cooling capacity of a three-symmetrical big-hole finned-tube refrigeration exchanger increases 3.0% to 16.8%,with an average value of 9.0%; the fin surface coefficient of heat transfer raises 49.7% to 80.1%,the mean value being 64.3%; the compressor COP (coefficient of performance) improves 15.0% to 30.2%,with an average of 23.0%; and resistance decreases 32.0%. During 5.5 h experimental time,only some holes on the surface of the three symmetry big-hole fins were jammed by frost to keep a predominant enhancement heat characteristic.
