ABSTRACT = {In the present study, an analysis of the heat and mass transfer in a ventilated
cavity in a warm climate zone was carried out to analyze, among others, the temperatures
and percentage of relative humidity (<i>RH</i>). The governing equations of the mathematical
model were solved through the finite volume method. We used the <i>k-ε</i> turbulence mode
to find the results of the variables of interest in seven climate records on a given day.
The velocity of the inlet flow of the air-H<sub>2</sub>O mixture was varied through the Reynolds
number (<i>Re</i>) from 500 to 10000. The outdoor weather conditions considered were
solar radiation, ambient temperature, and <i>RH</i>. It was found that at low velocities, flow
recirculation was formed inside the cavity which increased the temperature and concentration
of <i>RH</i>. For Re=5000 the flow is predominantly forced, which tends to set the values of
temperature and <i>RH</i> as 20°C and 20% respectively. The values of the <i>RH</i> increase in the
afternoon hours when the solar radiation decreases to the value of zero. However, the mass
transfer through the values of <i>Sh</i> is maintained with similar values in the seven weather
records. It was concluded that when air conditioning supplies air at speeds higher than
0.26 m/s at low temperatures it produces cooling with low <i>RH</i>, this causes discomfort, illness
and/or discomfort to the users.},
