Dear all,
I design a VAV system in EP, the type of all facility is autosize. The simulation is success, but i find there is a problem in the result file.
The temperature of cooling coil water oulet node is 18-20¡æ and the chilled water mass flow of cooling coil is small (the design chilled wter mass flow is caculated by the Plant Sizing ,and the delta T and exit temperature of the design Chilled water loop is 5¡æ and 6.67¡æ respectively),and the chiiled water is a constant water loop,thus most of chilled water is pass-by and the chilled water mass flow of Cooling Demand Bypass Branch get to two third of the design chilled water mass flow in the most running time.
I have changed the design condition of the Coil:Water:Cooling in all situation, but the resuts only have changed a litte and the overall trend is without change.
How can i do for it, or the heat exchanging effects of the Coil:Water:Cooling is rather well.
Best regards!
