I just star learning Trnsys and come up with a basic inquiry. Does anyone know how to create two airnodes within one zone in sketchup before exporting into Trnsys? We want to build a one-floor greenhouse mostly enclosed by glazing. The sloped roofs are also in glazing. We want to do the calculation concerning solar radiation and heat flow without HVAC system.
Currently we built two zones (the plant one and the air one) with the mutual surface set as virtual surface; however, even the two virtual surfaces disappeared when being exported into Trnsys, the two zones seemed to have no air flow connection. The results show that the plant zone has small range of temperature change, while the air zone has a much larger range. We realized we should build the sketchup model with two airnodes and one zone, but we didn't figure out how to do it. Another question is, in that case, is there anyway we can set different inputs according to the two airnodes?
Thank you in advance.
