It is extremely difficult to model the interactions between thermal zones which are connected by a large opening. If the zones are controlled to the same conditions, then there is little to be gained by making them interact, so you could neglect any conn...
When two surfaces are linked as interzone surfaces, the "exterior" side of these surfaces does not really exist. EnergyPlus links the two surfaces by using the inside temperature of surface A as the outside temperature of surface B, and the reverse. For...
Question: How to you calculate the enthalpy values for MaterialProperty:PhaseChange? 1. Choose a cold temperature and a small enthalpy value, such as -20C, and h1=0.1 J/kg 2. Calculate the enthalpy at the melting point(tMP) h2 = h1+(tMP - (-20))...
What is the meaning of 'Surface Ext Convection Coeff' report returned as 1000? I seem to remember that it means rain and this seems to be confirmed by weather data but what is the heat transfer coefficient in this case? or does rain mean some other mechan...
