DOAS system provide conditioned air to other system
Hi All,
I need help to simulate the following system in EnergyPlus: The building is high-rise building. Each floor is served by a separate air handling unit. There is one outside air intake. The outside air is heated or cooled by a dedicated DOAS system and then this conditioned air is provided to floor AHUs where it is mixed with the return air and further conditioned by variable air volume system with chilled water and hot water coils.
It sounds like you have one DOAS serving multiple AHUs which each serve multiple zones. This feature was just added to EnergyPlus with version 9.2. Since this is new as of 9/27/2019, I haven't tried implementing it yet, but make sure you are using the latest version of EnergyPlus otherwise what you are trying to do won't work. Hopefully someone else with experience using or creating this feature can answer your question.
