Experimental Setup and Methodology on Active Mechanisms for Enhancing Heat and Mass Transfer in Sorption Fluids (RP-1462) (ST-16-013)

Enhancement of heat and mass transfer in sorption fluids coulde improve the overall performance of an absorption chiller. Active mechanisums were proposed as a potential effective means to achieve this goal. A testing facility is needed to evaluate the impact on the performance of chiller after adding an active mechanisums. The challenges we face include the fulfillment of mechanism motion to driving extra heat and mass transfer in an absorber, the measurement of related variables and the stablility & repeatability of findings. The issues come from the fact that an absorption chiller is a close-loop system with large heat exchangers, has a low inside pressure and can sustain only small pressure drop along the refrierant loop. Measures are needed to exclude the impact from the vibration to the untargeted components in the system. In this paper, we introduce the details of the lab construction methodology, including the vibator, the auxiliary water loop system, and the measuring instruments. Then, we present several examples to show the operation and testing procedure and stability. At last, the experiment plan matrix and analysis methodology are presented which will be applied in the next phase experiment. This paper provides useful information of active mechanism experiment setup and test methodology for the researchers in the same area who may conduct related work.
