think I saw something about this in the last issue of the ASHRAE

<P>
<FONT size=-1><FONT face=Arial><BIG>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 South-East Asia. 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>
Neeraj<BR>
