2020-11-12 15:44:13 -0500 | marked best answer | Boundary Condition using SurfaceProperty:OtherSideCoefficients I'm setting the boundary condition for all 6 surfaces of one zone including a ceiling, a floor, and four walls using "SurfaceProperty:OtherSideCoefficients". When I checked the outputs of "Surface Other Side Coefficients Exterior Air Drybulb Temperature", I found out that one of the object (Ceiling_BoundaryCondition) is always zero during the simulation time even though all the inputs are set as same as other objects. I'm not sure what makes this difference and need your help. <"SurfaceProperty:OtherSideCoeffcients" Inputs> <"Constant Temperature Schedule Name" Input> Schedule:File is used for "Constant Temeprature Schedule Name" input and confirmed it reads the right temperature set I've made in .csv file. <"Surface Other Side Coefficients Exterior Air Drybulb Temperature" Outputs> The temperature calculated for Ceiling Boundary showing "0" not like other boundary conditions at the floor and walls. |

2020-11-08 18:22:43 -0500 | marked best answer | DOAS modeling with varying/scheduled OA cfm Currently I am modeling a high-rise residential building and specifically have issues on modeling DOAS.
Firstly, I've tried to mimic the DOAS system using AHU (vav) with min/max fraction of OA schedules.
So here I am wondering if there is any way to model this AHU (actually DOAS) with varying OA (=SA) CFM following the schedule value I made based on a real-life OA flow rate calculated each hour. In summary, wondering the way to model DOAS system in EnergyPlus, 1) 100% Outdoor Air 2) conditioned to 72F using H/C coils 3) Max OA (=SA) design air flow rate known 4) different/varying hourly CFM during the day known 5) so hourly OA (=SA) flow rates following the schedule, not the count of people or CO2 or else. Thank you so much for any kind of helps/insights/comments in advance! |
