Sensible Heat Load

Heat needed to change air or water temperature without a phase change.

Latent Heat Load

Heat absorbed or released when moisture condenses or evaporates — the hidden load air conditioners fight.

Coefficient of Performance (Cooling)

Cooling delivered per unit of work input — higher is more efficient.

Energy Efficiency Ratio (EER)

Cooling capacity in BTU/h per watt of power — a common AC rating.

Airflow (Sensible)

Air volume flow needed to carry a sensible heat load (imperial units).

Carnot COP (Refrigerator)

Maximum possible cooling efficiency between two temperatures (in kelvin).
