<p><font size=3 color=black face=Arial><span style='font-size:12.0pt;
font-family:Arial'>Dear all,<br>
<br>
Is there a (well documented) relationship between convective air flow against
the skin versus the thermal comfort expectation lowered (theoretical deg. F
raised for zone thermostat set-point)?<br>
<br>
I am trying to ascertain the cooling benefit of low power high-speed ceiling
fans that are prevalent in <st1:place w:st="on">South-East Asia</st1:place>.
They are especially useful in better air distribution and heat transfer from
the skin of the occupants via convection. For modeling the strategy is going to
be two fold -- [1] model the actual (low) fan power for the fans in each space
considered, and [2] model a different (higher) thermostat set-point expectation
since thermal comfort cannot be modeled in eQuest. Does this seem okay? --
Looking for peer validation.<br>
<br>
Thanks in advance.<br>
<br>
regards,<br>
