WL 230 Condensation Unit
Education / GUNT Hamburg / Thermal Engineering and HVAC / Fundamentals of Thermodynamics /
description

The experimental unit provides clear demonstrations of condensation processes in a glass cylinder. WL 230 has one condensation pipe with a polished gold-plated surface for dropwise condensation, and one condensation pipe with a matt surface for film condensation. The condensers are water-cooled. The cooling capacity can be determined. Sensors provide all relevant data which is indicated on digital displays. The measured values can be read on digital displays. The measured values are also transmitted directly to a PC via USB for further evaluation. The data acquisition software is included.

  The experimental unit WL 230 gives the student the opportunity to plot the vapour pressure curve for water during an experiment. Therefore the onset of the boiling of water is observed at different pressures in the reactor. The corresponding temperatures are noted. This experiment simplifies the understanding of the complex relationships in thermodynamics.
