Development of water sandwich-type wall closed chamber test system for radiators and radiant terminals

Based on the analysis of the characteristics of water cooling system, presents that it is needed to be solved for the switching problem between internal heat source of the closed chamber and the wall surface heat source, so as to meet the test requirements of both radiators and heating/cooling radiant terminals. Combined with the system schematic diagram, analyses the composition and function realization method for heat and cold source circulating system, heat media circulating system for closed chamber sandwich-type wall and chilled water supplying system of a sample. Presents the configuration of software and hardware of the data acquisition and control system. By reproducibility and repeatability test of the system, the system meets the error requirements of the standard of GB/T 13754—2008.
