[TRNSYS-users] R: How to make schedule for fan ?

[ahmad abbasian via TRNSYS-users]

Dear Toni

Thank you for your guidance.


I will read about the schedule type and inform you if any question is remained. I just have a drawback... In a single speed fan when the zone temperature is higher that 25 , the thermostat  turns it on , and when it reaches the 25, turns fan off. How should be control strategy for a variable speed fan to decrease the energy consumption in compare to single speed fan ?


Thank you

Hallo Ahmad,
you need to use a Schedule type….for a variable spped fan you need to control the Control Function of the fan because the Mass flow rate is Always the product between the Maximum flow rate and the CF. Everything is clear?

I need a fan to be turned on at 8 and turned off at 18 every day during the workdays and to be turned off all over the weekend days.  How should I implement it?

using the single speed fan, the fan is just turned on or off, but using the variable speed fan how it works? I mean that when the part load is in operation?


Thank you
