Cooling load
The cooling load is equivalent to the rate at which heat must be extracted in order to maintain a constant indoor temperature
The component of cooling load
1.Heat gain during summer due to conduction, convection, or radiation are all sensible load which tend to increase the DBT of room air
2.The Transmission load is positive gain in summer
3.People loss part of their body heat by perspiration which is a latent load which tends to increase  the moisture  content of the air
4.The ventilation  air drawn in from outside  can be both a sensible and latent load.
Space load ( SL) is maximum sensible heat generated in the space 
SL = Solar radiation + Transmission+ Electric power+ People (sensible heat)
Equipment  Load ( EL) is maximum total heat transferred to the cooling coil ( including that for cooling / dehumidifying the  ventilation air )
EL = Solar radiation + Transmission+ Electric power + People + Outside Air
