Therefore when fresh air enter the building, the temperature decrease and the relative humidity reach 100% really quickly. There is condensation and thus heat release (latent heat). This amount of heat is high specially when the outside air (around 30°C) has to reach a temperature of -40°C!<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I decided to analyse the TRNSYS output: QLATG (latent energy gains including ventilation, infiltration…). Then I’ve compared it with the sensible heat and I noticed the following:<o:p></o:p></p><p class=MsoNormal>Sensible heat =10000 x Latent heat.<o:p></o:p></p><p class=MsoNormal>I was expected that the latent heat would have been about the same as the sensible heat (calculation done with a mollier diagram).<o:p></o:p></p><p class=MsoNormal>I decided to check the relative humidity inside the rooms: the relative humidity is almost always at 100%.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Question: I’m wondering if TRNSYS considers the heat released during condensation. The impact is probably huge on the energy demand of the building.<o:p></o:p></p><p class=MsoNormal>Does anybody know if TRNSYS can give me the energy which is released when the humidity inside the air is condensated? <o:p></o:p></p><p class=MsoNormal>I did not fix any humidity level inside the rooms.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks a lot for your
