WebCooling Capacity. The cooling capacity is defined as the amount of cooling (usually expressed in terms of kW or tons of cooling) delivered by the system divided by the … WebApr 1, 2006 · The kind of Btu that makes up 12,000 Btu in a ton of cooling is called total heat. Total heat is made up of two kinds of heat: sensible and latent. In heating mode, all of the Btus are sensible heat. An 80,000 Btu output furnace should deliver 80,000 Btu into the duct system. Cooling removes two kinds of heat. The 12,000 Btu per ton is made up ...
