Space Heat Gain and Space Cooling Load
Space heat gain is the rate at which heat enters a space, or heat generated within a space during a time interval.
Space cooling load is the rate at which heat is removed from the conditioned space to maintain a constant space air temperature.
Figure 3 shows the difference between the space heat gain and the space cooling load. The difference between the space heat gain and the space cooling load is due to the storage of a portion of radiant heat in the structure. The convective component is converted to space cooling load instantaneously.
