Hi everyone,
I am now facing some problems regarding HVAC zoning.
1 I have a project of a 3-story school building. For each floor, I have
different zoning plans. However, in schematic wizard, I can only draw one
type of building footprint and HVAC zoning plan. Can you help me design
different zoning plan in each floor?
2 I tried to find loads report from SIM file and I found that it was said
'Space temperature used for the loads calculations is 70F'. However, in
Air-Side HVAC, the default indoor design temperature for each zone is 75F
in summer and 70F in winter. Can I change the temperature for loads
calculation from 70F to the default design temperatures?
3 What is the function of zone group definitions?
4 I am not sure about some default names of the zones:
In Air-side HVAC, SW Zone(fG.z1); SW SpcPlen(fG.z1);
In Internal loads summary, SW Space(fG.s1); SWSpPlen(fG.s1)
Can you help me explain them?
I really appreciate your help! Thanks a lot!
Best,
Siliang
Hi Siliang:
1) You cannot do anyone more that one floor plan in Schematic Wizard. If you change to Design Development (DD) Wizard, you will be able to do multiple floor plans that are different.
2) LOADS (before air side) are the external and internal loads calculated on the base temp of 70 DegF. That is fixed.
When you move further down the program (Air Side), your space temperatures will be controlled by the 75 Cool, 70 Heat thermostat setting. THOSE you may change.
3) Zone group definitions assign the different space to different HVAC zones. You may have spaces on multiple floors assigned to a single HVAC system for example.
4) In the definitions of the spaces, you will note the "s" designation. In the HVAC portion, you will note the "Z" (for zone) designation. Every space (containing windows, walls people, lights, etc) MUST be assigned to an HVAC ZONE.
