- The cooling load calculation determines the unit size there are two capacities that enable the equipment to provide comfort the first is sensible capacity how much sensible heat can the unit remove sensible heat is the heat energy measured on the dry bulb thermometer the second form of heat is called latent or hidden heat this is heat held in the humidity in the air removing this heat does not affect a thermometer however removing the heat held in the moisture in the air greatly increase comfort a properly sized unit removes both forms of heat producing a comfortable living space an oversized system cycles on and off too quickly and does not properly remove humidify producing an uncomfortable living space select the indoor and outdoor equipment combination based on the manufacturer s engineering data after the proper equipment combination has been selected satisfying both sensible and latent conditioning requirements the system must be properly installed only then can the unit provide 13
