Vortex tube cold test device

R434 a vortex tube cold test equipment, devices: 1, this is a demonstration of the vortex refrigeration principle teaching laboratory equipment. 2, the vortex tube refrigeration equipment is the role of the vortex tube by passing a high-speed air swirl isolated cold, heat two streams, obtained by the use of air flow cooling method, the core components include: intake manifold, nozzle, swirl chamber, plate, cold end of the tube, the hot end of the tube and flow control valves. 3, is provided on the device panel meter, thermometer, power meter, pressure gauge, etc. to record experiments, system operating parameters. Second, the experimental features: 1, measure input electric power conversion efficiency, heat output as well as between them. 2, the experimental device can be plotted as a heat pump performance curve at work. 3, may draw the actual vortex refrigeration cycle curve on the pressure-enthalpy diagram and comparison with the ideal cycle. 4, verifiable cold end of the tube and heat energy balance between the end of the tube. 5, assess the impact of the pressure ratio of the compressor for compression efficiency.
