Based on the comfort zone psychrometric chart
from Figure 5.3.1 in Standard 55, space thermal environmental conditions are determined (i.e.
The comparison focused on the impacts of external shading strategies on indoor comfort probability based on the psychrometric chart
plot for ASHRAE-55 2013 comfort metrics.
The psychrometric chart
in Figure 2 illustrates the conditions in which the chilled water plant is able to operate at full economizer mode (48% of the year), partial economizer mode (40% of the year), and with the cooling tower off, which highlights the benefits of the medium-temperature chilled water loop.

Hence, Garcia's map is appropriate for this research's selection of site that will provide the basis of the diagnostic analysis of the climate and microclimate of it, and consequently, it is also suitable for the creation of psychrometric chart
for housing in Ecatepec zone.
ASHRAE, for example, offers a handful of apps, including an interactive psychrometric chart
, a duct fitting database, and searchable versions of standards with built-in calculators.
Included is a psychrometric chart
, which can be used to determine optimum drying.
On the psychrometric chart
, this process is represented by a horizontal movement along a constant humidity ratio, dewpoint temperature, or vapor pressure line (ASHRAE 2001).
The good news is that the Mollier charts fur the different formulations are provided along with a psychrometric chart
. You don't have to make your own; you can download them ...
In addition, the unit itself has a psychrometric chart
on its cover and a humidity calculator slide rule in the carrying case.
The software calculates the psychrometric points of the process and the resulting space conditions, and then displays the process on a psychrometric chart
Knowing the ambient (dry bulb) temperature and relative humidity, the total water vapor content or humidity ratio can be interpolated using a standard psychrometric chart
. Considering that 1 lb of blast air will melt 1 lb of iron, the air required for a given melt output easily can be calculated, making sure to correct the air density for temperature and pressure.
