Here is the issue. I want my unit ventilator (Group Name: Zone HVAC Forced Air Units, Object Name: ZoneHVAC:UnitVentilator) and radiant cooling to work simultaneously, in this case I want unit ventilator to act as DOAS taking care of entire latent load of zone and partially sensible load. Thus, you can see in the .eio file that 100% OA air is conditioned through cooling coil installed in unit ventilator. I have the following queries: 1. Autosizing my Zone1Unt Vent Outlet air temp. gives 13°C, however, the output variable sheet shows indoor air temp. as high close to 28°C (thermostat has been set to 24°C). 2. Sizing Zone Cooling Design SAT has been mentioned as 13°C, when I reduce it to 11 or 12 °C, zone air temp. increases from 28° to 33°C (on a particular day in June). 3. Sizing Plant Design Loop exit temp. is mentioned as 10°C and in CHW Loop temp schedule I have mentioned 15°C. So, on which temp. my loop is running. Is it that because of this my indoor room air temp. is not coming close to setpoint. When I increase this loop exit temp. from 10°C to 15°C again the same thing happens zone air temp. increases from 28° to 33°C (on a particular day in June). Can anyone suggest the mistakes which I am making. Why the room air temperature is not getting close to the setpoint? regards, SACHIN SHARMA --- On Sat, 3/24/12, Jean marais <jeannieboef@xxxxxxxxx> wrote:
