Re: Negative Conduction from External Wall in Tropical Count

Hi

Could anybody elaborate on the answer given by geshen516, I'm particularly interested in this especially if you consider the heat conduction at an instant in time and any ignore effects of heat lag through the material.

I have a situation whereby I want to verify the conduction gain through a ...

2 identical models (except zoning) BUT different results

Any comments / observations welcome on the following:

I'm comparing two identical models with the only difference being the zoning of the space to obtain a temperature profile.

The basic building is a one floor building with a pitched roof.

The first model is created as a one zone and the ...

Re: Anomaly with heat transfer between 2 zones with a hole

John, thanks for you responses so far

I've placed an internal hole in one of the side walls to check that MacroFlo is working and it does account for air movement between these spaces, however the phenomenon with zero flow between the hole in the roof zone and living space remains.

Interrogating ...

Re: Anomaly with heat transfer between 2 zones with a hole

Hi John

I assume that when you say MacroFlo enabled you mean that the MacroFlo link is checked when you run Apache Simulation, and if so then I have been. I'm relatively new to IES but my understanding is that this applies the MacroFlo templates to the openings (windows / doors), and I'm not sure ...

Anomaly with heat transfer between 2 zones with a hole

I am conducting a project which is considering the effect of different roof designs on the indoor living space temperature. I have created a simple model, located in Nairobi, which consists of a living space and a roof zone.

The roof is constructed of tin which leads to very high temperatures in ...
