I am doing One Floor Radiant Cooling. since I am not getting the desired temperature, I have removed all the sources of heat generation and just kept envelope (I cannot remove that,although). I have considered a temperature as low as 5 degC and could attain the desired temperature. few things are noticed
1) The delta T between the Floor surface temperature and air temperature is around 12k. why so huge delta T? there is a delta T between source and surface which is because of thermal resistance of the intermediate layers which is understandable. but the MRT is comparable to Air temperature. does this mean, the cooling is not happening?
please see the attached image. how to pull this huge delta T
please see the attched IDF file
