For indoor db temperatures other than 80˚ F, measure Indoor db and Indoor CFM, and plug these into the formula below. Measure outdoor db and indoor wet bulb,apply these to the chart above, find MBh and S/T, and plug these into the formula below. (Note: if indoor db is the only thing changing, total capacity, MBh, stays the same.)Sensible Capacity at Indoor db LOWER than 80 ˚F = ( MBh x S/T ) -Sensible Capacity at Indoor db HIGHER than 80 ˚F = ( MBh x S/T ) +( )( )( 80 - Indoor db ) x 835 x Indoor CFM1000( Indoor db - 80 ) x 835 x Indoor CFM1000428 04 5100 00 11
