[TRNSYS-users] Ventilation schedule

[hotline via TRNSYS-users]

Issam,

You can use TYPE 2 hysteresis controller to get a control signal of 1 or 0, depending on the ambient and room temperature.
Check out the manual on page 4-13 ff.  where the Type is described and where it is explained how to set it up. In TRNSYS 18 (will be released soon) there is the TYPE 168, which was developed to tackle exactly this issue.

Best,

Betreff: [TRNSYS-users] Ventilation schedule

Dear all,

I have a query regarding ventilation schedule setting in Type 56 of TRNSYS.  I want to establish a simulation with air change scenarios in winter and 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?
