Hi Adnan, You have to model the flow from the AHU in TRNFLOW, e.g. with a fan. The inputs for TRNFLOW for the temperature, humidity and mass flow are the outputs from TYPE 928. I hope this will help you. Regards, Matthias From: TRNSYS-users <trnsys-users-bounces@lists.onebuilding.org> On Behalf Of adnan rasheed via TRNSYS-users Hi everyone, I am using TYPE 928 (fan coil unit) for room heating, which gives me output of air temperature, humidity and mass flow rate to introduce into the building for heating during night time. meanwhile i need to use natural ventilation in daytime using TRNFLOW. It seems like that TRNFLOW is not working when I switch on the ventilation type or vice versa. what can i do to resolve this problem? in the real building i natural ventilation and fan coil unit are both working.
