I am having trouble understanding conceptually how HAP handles certain cooling loads. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>In my case, I have two adjacent rooms, one of which is air conditioned to 68 deg F and 50% RH, and the other does not need any A/C, just ventilation. There are a few set of rooms at one end of the station and another set of rooms at the other end of the station. Some of the rooms need A/C whereas some others don’t.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>In HAP, I haven’t been able to figure out, how to assign an order to the rooms. I would think this order is important to assess the heat transfer between the rooms correctly and correspondingly calculate the overall heat load.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>In order to estimate the heat load, I would like to have an independent a/c system for each room that needs to be airconditioned. Hence, I am using 5 CAV’s to air condition 5 spaces (rooms) and I am also using 4 CAV’s to ventilation ( not A/C) to ventilate the 4 non-A/C rooms. Also, there are corridors and windows.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>As mentioned earlier, I haven’t been able to figure out how to arrange the rooms in an order and how to group them. In the space properties, I see a tab for Partitions. But, it allows for a maximum of 2 partitions only. I am not sure if this is the way to specify internal walls.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The tutorial only comes with 2 examples, that does not consider a case where the rooms are conditioned differently.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Any suggestions would be greatly appreciated.<o:p></o:p></p><p class=MsoNormal><o:p>
