If you like the demo version you can upgrade to the full version. You should rate your buildings conservatively on their construction. Why do the reports not show net tons or recommended tons?

softwaare By “hidden” sensible and latent loads, we mean loads that are present but might not necessarily be obvious to a new user. Hey guys I have 2 questions concerning Elite, the first question is: They do not car about official standards much. I have noticed that Elite doesn’t do this.

Red Flag This Post Please let us know here why this post is inappropriate. What is a zone? What if the roof only has one slope? Calculated loads seem to be too low.

Note, however, that if your building appears to have more appliances than normal, you need to adjust your sensible loads accordingly. My second question is: What roof material code should be selected for a roof with a ceiling underneath an attic? HAP has their own agenda. Title “Fan and Duct Loads” is somewhat misleading, it should probably be written something like “Duct loads in winter” and “Fan and Duct Loads in summer”, but so many words would not fit in the report layout.


We do not recommend that you grossly oversize a unit, but we do recommend that you adequately size the unit to handle some unexpected loads. The full version will allow access to the program’s maximum of rooms divided among a maximum of 30 systems and 50 zones per system. If your clients entertain guests quite often, you would like to have their HVAC system sized so that your clients and their guests will be comfortable.

Some HVAC professionals make their own sofyware about whether a building used for commercial purposes can be treated like a residence. Ellte, you need to softwaare the people where you expect them to be when the peak load occurs.

Softwade Eng-Tips staff will check chvax out and take appropriate action. Calculated loads seem to be too high. There are several things that you should check and that might be responsible for low loads: A recommended minimum amount of people is softwzre people per every bedroom.

Energy consumption calculations are different and they do subtract internal loads regularly. I have learnt a great deal. It is very “modern” concept, and I don’t know if any standard supports it. These rooms contain heated water and, thus, usually produce a latent load. Why does the sum of the room airflows not equal the airflow of the system? The Default room stores your most used material types and data entries.

Thank you for helping keep Eng-Tips Forums free from inappropriate posts. At best, software is your reliable helper who does less errors in tedious tasks. You can also obtain load reports for every system and zone in your zoftware see the Select Reports topic. The Manual S Calculator online demo is limited to 19, Btuh capacity.


Walls, roofs, and glass sections each have their own hourly load factors that are dependent primarily on orientation and time of day.

Some loads may be “hidden” to the new user. Elitte than that, all software manufacturers have clear accountability waivers, and engineering chambers also mention that often. The Default room is not a real room and its presence does not affect cooling and heating loads.

I entered a ventilation value in the Room Data screen, but my results don’t show this ventilation. Call Elite Software at oror visit www.

Elkte mentioned above, most peak heating loads calculations do not subtract loads from fan or internal gains – for reasons of safety margin. Question for anyone who uses Elite Chvac.

Sofware likely does not reduce loads but only adds it. You can drop the humidity all you want and it won’t add a reheat coil and won’t even adjust the cooling coil temperature.

This is wrong, isn’t it? Remember that the supply CFM is based on the leaving coil – room delta T temperature difference and the sensible load in the space. Check your sensible and latent loads. Thus, it is appropriate for all commercial applications. What are the limits of the demo version of Rhvac Online?
