<p>Dear all,<br>
</p>
<div style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"><span style="BACKGROUND-COLOR: white">For my project, I have to simulate the heat transfer in a swimming pool. This swimming pool is divided (horizontally and vertically) into 36 zones. Sources of heat are the
lighting and the heating of the water which is 30°C. There is a ventilation in several zones which blows air at 35°C. Because I need some zones to have only one surface (which is not possible in TRNSYS), there are walls (</span><span style="BACKGROUND-COLOR: white">interior
wall</span><span style="BACKGROUND-COLOR: white">) which are only composed of air.</span></div>
<div style="MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px">When I simulate over 3 years, I obtain negative temperatures in somes zones during winter. What is not possible in a swimming pool where temperature do not generally come down below 20°C. I notice that the temperature
chart of a zone follows the one of the ambient temperature of the place where is situated the swimming pool.<br>
Do you have an idea to solve my problem or an idea of something (a parameter in TRNSYS or something like that) I forgot in my simulation ?</div>
