Question for anyone who uses Elite Chvac. – HVAC/R engineering – Eng-Tips

Some of the main items are building dimensions, infiltrations, people, and “hidden” sensible and latent loads. If you like the demo version you can upgrade to the full version. What roof material code should be selected for a roof with a ceiling underneath an attic? Some loads may be “hidden” to the new user. The load adjustment can be made for each room on that room’s Room Data page. I always leave it, i. They do not car about official standards much. If there is any doubt as to the “tightness” of the construction on a building, select your infiltration value somewhat on the high side.

Other than that, all software manufacturers have clear accountability waivers, and engineering chambers also mention that often.

Chvac does give you overview of all loads in good manner. These rooms contain heated water and, thus, usually produce a latent manaul. All of these methods employ more sophisticated procedures than what Manual J uses.

Also, if the latent loads are a high percentage of the total loads, the supply CFM will calculate out less than CFM per ton even with a 20F delta T.

Promoting, selling, recruiting, coursework and thesis posting is forbidden. Nevermind cvac east glass has more heat gain in the morning and less heat gain in the afternoon. Next, make sure that you have enough people in the building.

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. It is very “modern” concept, and I don’t know if any standard supports it.

Latent loads from bathrooms and sensible equipment loads from televisions are two such examples.

You can calculate reheat in Elite psychro module and add it to chvac air system. You can also obtain load reports for every system and zone in your project see the Select Reports topic.

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. When I drop the humidity of the air below a certain point, reheat coil should be added in order to reheat the air to maintain the sens zone temperature.

In Manual J, east glass has one summer load factor. Maybe I am becoming too “old school”, but sometimes on these forums try to sharply point out to young engineers to not expect software packages to do design work for you.

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. The Default room stores your most used material types and data entries.

Close this window and log in. You should study HAP help and manual to see how they formally explain that. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Unless the roof is referenced by a skylight window s in Glass entries on the Room Data page, the direction of the roof will always be UP, no matter what direction you specify and, therefore, will not affect the loads.

Since the sensible gain for windows and skylights at the system level is always based on the average load procedure plus any AED excursion load, the sum of the room cooling airflows will be larger than that of the system in this case.

I just manuql to know which is right. The direction of a roof is meaningful softwqre if the roof has a skylight window s. Thus, a north wall receives the same load factor as a south wall.

Why do the reports not show net cchvac or recommended tons? Check your people loads entered on the Outdoor Design Conditions page and make sure that reasonable values have been entered for active and inactive loads per person. The load calculation demo version is limited to three rooms, 15′ wall lengths and 8′ wall heights. Go to the following page: The information on the Default Room Data page does not have to be filled out and your input is not checked for errors hence the absence of Evaluate button on the Default Room Data page as opposed to the Room Data page.

After all, you can occasionally find a regular house converted for use as a beauty salon for example.
