how to set temperature in Air loop?
Hello. I'd like to ask you how to set setpoints of heating coil? I made a idf file with AirLoopHVAC, and AirLoopHVAC consists of fan, cooling coil, and heating coil. In Sizing:Zone, I put [Zone Cooling Design Supply Air Temperature] 12.5C, and put [Zone Heating Design Supply Air Temperature] 50C. Also I checked [Rated Outlet Air Temperature] is set as 32.2C in Class List [Coil:Heating:Water]
However I found out Mixed air temperature didn't change after went through the heating coil. (heating coil inlet air temp=18, and heating coil outlet coil temp doesn't change at all) So I checked heating coil water flow rate, and water flow rate=0kg/s.
I wanted to set heating coil outlet temperature 30C, and I expected that heating water flow rate would be automatically changed in order to reach set point 30C, but it didn't work. So I can I fix heating coil operation as I intend? please help!!
