[Equest-users] I need to get help to "Cooling Setpoint Control: OA Reset" (urgent)!

[Jeon, MiYoung]

Energy saving from OA-reset control depends on the design values and weather data.

If you model OA-reset control, electric consumption for the space cool, heat rejection and pump & fan will be reduced.

I just ran a test to inform you the effects of OA-reset and as a result, an electric consumption saving is 2 %.

This is just one of various cases. In order to get a precise result, you should predict the saving using the hourly report and  weather data as well.

Thank you.

Thanks for your reply
I already tried this but my problem is not that the result is not much of what I expected.. not much saving from this OA rest control. I am wondering if I did it in a correct way

Dear Jasmine,

You can model ‘OA Reset Set-point control’ using chilled water loop’s controls.
There are four control sequences. (Fixed, OA-reset, Scheduled, Load-reset)
See the picture below. If you need help, feel free to contact me.

Thank you.

Dear eQuest expert,

Is there anyone who have experienced with modeling the chilled water supply reset according to “OA Reset Set-point control” in Cooling? In other words, chilled water supply temperature will be changeable according to OA temperature (Lower OA temp, high chilled water supply temp). Can you help me out on how to set up the model in order for this to be working successfully.

I really need to model this as accurate as possible. Your help would be greatly appreciative. Thanks so much for your help in advance. Cheers
