Thread-topic: Type 557 / double-u tube

Hello everyone,

I have a question regarding type 557 in TRNSYS. There are mainly two type (U-tube & Tube-in-tube). How can a 2U-tube ground heat exchanger be modelled? Should I change some parameters of the single U-tube one?

Is there probably a more user-friendly mathematical reference for type 557 other than type557-DST manual (I mean overview and mathematical reference like other TRNSYS components)?

Best regards,

Hoofar Hemmatabady
