Investigation on Switchable Evaporation and Condensation Horizontal Single Tube Heat Exchange Experiment Platform

Abstract

Abstract In this experiment, the switchable evaporation and condensation horizontal single-tube heat exchange experiment platform is designed. And the equipment selection and construction of the experiment platform is completed through the design calculation. The experimental results show that the thermal balance error of the test section of the experiment platform is less than 15%, especially the condensation and evaporation experiment of R22 in 12.7 mm copper tube, and the evaporation experiment of R410A in 9.52 mm copper tube, the thermal balance error of the experiment is less than 5%. The experiment platform can realize heat exchange experiments with different refrigerants, and the test section of the experiment platform can be standardized replacement of tube types according to research needs.
