Dear Users Because my problem is very important for me I will ask again to remind my issues. I use type 56 (TRANBuild), type 97 (CONTAM) and type 3c (fan) to simulate ventilation. A. The problem is that each type have other outputs/inputs units: - It seems to me that outputs of type 97 are air change rate per hour. - Flow rate in type 3c and 56 is given by kg/hr. - I would like to get results in m3/hr. So my questions: 1) Should I do some conversion of units between fan (type 3c) and CONTAM (type 97) or between CONTAM and Type 56? 2) How can I get air flow in m3/hr or kg/hr form type 97? B. The second issue is that I calculate year-round infiltration and exfiltration for my model (natural ventilation) using type 97 and type 28b (Simulation Summary) and it appear that exfiltration is much larger… How it is possible??? It seems to me that exfiltration and infiltration air should be equal if there is no other way for air. Regards, Karol ------------------------------------------------ Karol Bandurski MSc.
