[TRNSYS-users] Ventilation schedule

[Issam Sobhy via TRNSYS-users]

Hi,

I would like to contact you about a question that i have regarding setting
a ventilation schedule in the Type 56 of TRNSYS.

Indeed, i want to establish a simulation with air renewal scenarios in
winter and also in summer.

In winter (Nov ---> April): the rate of air change is 1 vol/h from 8 a.m to
6 p.m

In summer (May ---> Oct): the air change rate is 4 vol/h, when the ambient
temperature is lower than the air temperature inside the zone, otherwise
the air exchange rate ventilation must be zero?

Please find enclosed the TPF of a single thermal zone in which i wrote the
equation, but i do not know yet how to do this for the summer ventilation
condition.

Do you have any idea how to deal with this type of execution?

I appreciate your cooperation and thank you for your attention.
