Dear Sir/Madam,
There are two systems connected together to supply the air to the same zone, namely the CAV air condtioning system with fully outdoor air and the CAV air conditoing system with room air return. How is the system constructed in the EnergyPlus file?
For the detail,
I established two branches for the cooling process. The outdoor air is treated by "CAV air condtioning system with fully outdoor air" and the returen air is treated by "CAV air conditoing system with room air return". The treated air after these two loop is then mixed by a mixer box in "plant-condenser flow control" and a duct is created as a branch loop for mixing. The same method has been done on outlet loop of zone oulet but use the spliter as for spliting the return air back into return air node.
However, the serve statement as below was shown. Is it possible that a zone outlet connect to two return air branch inlet? Please help to solve the problem. I am urgant to establish this system. Look forward to your reply and please reply as soon as possible.
Many thanks in advance.
