Using water wall like air humidifier

Abstract

Abstract This paper presents experimental results of the study of falling water film evaporation from water wall. The contribution is divided into several parts. The introduction is devoted to the theoretical part of the use, then the prototype of the water wall is presented and its most important parts are described. In order to verify the humidification performance of the water wall, experimental verification under laboratory conditions (climate chamber) was chosen. One task for the definition of water wall evaporation potential is to determine and develop the measuring system, which is clearly defined in article. The present document describes the methodology and boundary conditions during experiments. Plate heat exchanger ensured a water temperature in the system approximately 23 °C hot during all measurements. A total of 4 measurements were performed at different air temperatures and relative humidity. The results showed that at different temperatures and relative humidity of air, the water wall has a different humidification performance.
