Case study: Evaluating comfort indexes in line with international standards

Figure 1 illustrates the HVAC performance under following specified key parameters:

> 2 air inlets at the ceiling across the entire width of the room:

T=20 C, 2 Kg/s

> 3 air outlets located in the rear wall (red taps)

> 2 diabatic walls, facing the street, with assigned transmittance

> External air temperature T=0 C

> People surface temperature T=37 C

Notably, on the rear side, the presence of over 20 individuals leads to improved heating conditions and a higher temperature. However, the presence of glass partition walls poses an obstacle, hindering temperature uniformity, as evident in the vertical section displaying the temperature map.

Towards the front of the room, a distinct temperature stratification can be observed. This stratification is reflected in a similar pattern within the heat flux map along the external wall.

Figure 2 provides an overview of the Comfort Indexes PMV & PPD, along with the computed indexes within the two volumes depicted in the render.
