Effects of Atmospheric Gases on the Efficiency of Heating and Cooling Supply Components: Experimental Investigation of a Plate Heat Exchanger
Abstract
The paper presents measurement results for the influence of bubble flow (gas volume fraction up to 6 %) on the pressure drop und heat transfer in three plate heat exchanger test objects, which are operated with water as heat transfer fluid. The gas content effects the efficiency and auxiliary energy consumption of solar thermal systems. Therefore, the plate heat exchanger as one of their main components is investigated in detail. Furthermore, the research project is going to examine the effects on a solar thermal flat plate collector field.
