- Abstract
- In the paper, a detailed model for a thermosiphon water heater, to be included in version 12 of the TRNSYS hourly simulation program, is presented. The model utilizes collector parameters determined from standard tests. The component is general for systems with or without in-tank auxiliary heaters. Results of the model compare well with experimental results for both auxiliary energy usage and thermosiphon flow rates and temperatures. TRNSYS is then used to investigate the design and performance of thermosiphon systems for a variety of conditions.
