Re: [TRNSYS-users] By-pass in TRNSYS

Dear Cristi,

You may build a schedule with equation tool or use special type in TRNSYS to define your seasons.
With equation tool you will have something like :

• WINTER = LT(TIME,1920)+GT(TIME,8520)
• SUMMER = GT(TIME,4848)*LT(TIME,7056)

Then, control your exchange with an equation like

• EXCHANGE = WINTER + SUMMER

Your exchange works in winter and summer (=1), and by pass (=0) the rest of the time

Best regards

Hello everybody!

 

I’m relatively new in TRNSYS and I want to simulate a ground-to-air heat exchanger. My question is: how can I simulate the by-pass for this type of exchanger? My exchanger is used to heat/cool the ventilation air during winter/summer, but in the inter-season is no need to use it. So, it must be by-passed. Thank you for your attention!
