ESS 컨테이너 냉각용 루프 열사이폰 열교환기의 다양한 작동유체에 대한 특성과 성능 실험
An Experimental Study on the Characteristics and Performance of Various Working Fluids of a Loop Thermosyphon Heat Exchanger for ESS Container Cooling
Experiments were conducted on the operating characteristics and performance of various types of working fluid, filling amount and heat flow rate of a loop thermosyphon for cooling ESS battery container. As results of performance test on various working fluids, HFE-7100 and R-134a as a working fluids showed unstable operating and low performance due to vapor pressure drop, and performance was improved by increasing the number of vapor lines for reducing a pressure drop. In this study, n-pentane was more stable and showed better thermal performance among various working fluids.
