Hi, I'm currently trying to run a Thermal Simulation and I'm trying to create my profile for the heating in the building. My building occupied between 7 am and 10 pm and I only want heating to come on when the dry resultant temp in the rooms are below 21 deg say months Jan to Mar and Oct to Dec. I've created a timed absolute profile which i think is fine but I'm not to sure what stops the heating from continuing to be on when the desired temp in the room is reached say 23 deg. As it is now the dry resultant temps in winter months are higher than summer which doesn't make much sense. (other than the heating on during winter and off at summer). Any help/ideas will be grateful.
Thanks, Gary
Heating Profile
Re: Heating Profile
Hi,
I'm not quite sure how you would go about this. The usual method and the way the VE is designed to assist is to control conditioning based on the room air temperature.
The only way this might be achievable as you desire would be to create a daily modulating profile with the hours outside 7 - 10 set to 0 (off) and the hours from 1 - 10 set to a formula (tdr<21). You can then create a weekly profile that references this one say Monday to Friday and at weekends uses the Always off profile (assuming we're talking about a building occupied Mon to Fri), and then create an annual profile using this weekly profile Jan - March, off conts April - Sep and the new profile Oct - Dec again.
In the thermal template you can then assign this as the Heating profile, this way when the profile is in use the formula would ensure heating only occurs when the room dry resultant temp is less than 21. However, you would still then need to apply a Constant setpoint of say 21 that would be controlled by the room air temp.
It's the room temp setpoint value that controls the heating in the end so as sono as the air temp went over 21oC it would switch off and this way you'll never get it overheating the room more than you want.
Hope this makes sense, I think it's the closest you woul dbe able to get to what you want (it's the only approach I can think of anyway)
