Proper distributions should have air directed toward areas of greatest heat loss. Multiple units may be used to greatest effect by positioning units around the perimeter.
outside temperature or unheated spaces. Calculate door as all glass. 3. Select heat-transfer coefficients from the table below (or the ASHRAE Handbook) and compute the heat-transmission loss for each area in BTU/HR by multiplying each area by the heat-transfer coefficient and the temperature difference. 4.
