Dear Sara, thank you for that. I need to do that to simulate an intelligent heating control system. The recoded data I have got shows that the set point temperature varies throughout the day. Arianna

Dear Arianna,

In control file you can define different day types and in each day type different periods in day. This means that in theory you can have one set-point for every hour of every day. But practically you can't define 8760 control for a building. If it is important for you to keep the 24 hours profile for set-point temperature, you can divide the year to 3 or 5 seasons and for each season specify a different set point (depends on the season if cooling system needed or heating or both or neither).
On the other hand you can define your set point for cooling and heating for whole year (1 day type) and 24 hours. However, I am not sure what is the benefit of having different set-point for every hour? The HVAC system always have one set point for cooling and another for heating unless they are setback control which changes for night and day as well.

Hope that helps,

Hi All,

my previous email may not be that clear so I will try to be more specific. I would like to use a set point temperature that varies throughout the day. Can I do that in ESP-r? Please let me know,

thank you,

Arianna

Dear All,

I would like to use some monitored internal temperature as a temperature set point to calculate the heating load. I have daily averages for the month of January at the moment, do you know if there is a way in ESP-r to do that? I may be able to find some hourly data . Please let me know,

Thank you

Arianna
