ENVIRONMENTAL CONTROL FOR AGRICULTURAL OR SMALL BUILDINGS
Saturated vapour pressure at the same temp.
0.892 m3 /kg
= 414,350 kJ/hr
Where: Q is the total heat transfer rate through an element (W)
A is the area of the building element (m2)
U is the coefficient of heat transfer for the element (W/ m2.o K)
is the temperature differential across element.
For the building as a whole, the total heat exchange rate will equal the sum of the Q values.
Total Heat Loss = 1844 W
