Problems solved by technology
[0002] Existing studies on single-tube heat transfer experiments mostly use experimental devices that can only meet the single heat transfer characteristics of evaporation or condensation. The physical parameters are also relatively simple, if both the evaporation heat transfer experiment and the condensation heat transfer experiment are carried out, it will not only expand the occupied area, but also increase the cost

Embodiment Construction
[0022] The usage method of the present invention will be described in detail below by taking specific embodiments as examples in conjunction with the accompanying drawings.
[0023] as attached figure 1 As shown, a schematic diagram of a switchable evaporation and condensation single-pipe heat exchange experimental device of the present invention includes: a refrigerant circulation system, a water circulation system and a real-time data acquisition system.
[0024] Refrigerant cycle system includes: liquid storage tank 1, dry filter 2, subcooler 3, diaphragm metering pump B4, pulsation damper 4, second plate heat exchanger HE2, experimental section 5, third plate heat exchanger HE3 .
[0025] In the refrigerant circulation system, a bypass circuit equipped with an electric regulating valve M1 is connected from the liquid receiver 1 to the B4 outlet of the diaphragm metering pump. When the refrigerant flow rate is too small, the refrigerant flow rate at the B4 outlet of the di...
