HVAC COOLING LOAD CALCULATIONS AND PRINCIPLES Sensible Heat Gain – is the energy added to the space by conduction, convection and/or radiation. Latent Heat Gain – is the energy added to the space when moisture is added to the space by means of vapor emitted by the occupants, generated by a process or through air infiltration from outside or adjacent areas.
Air Conditioning Calculations. When choosing an air conditioner, usually a 1 HP (horse power) equipment is able to remove 9,000 BTU/hr of heat. With better technology, some machines are able to remove 10,000 BTU/hr of heat with the same capacity. The higher the listed BTU/hr, the greater the cooling capacity.
Cooling Flow Calculation. Forced air cooling of electronic components results in a dramatic improvement over natural convection cooling. Reduction in the temperature of the air in the vicinity of the components being cooled. Improvement in the heat transfer coefficient of the components transferring heat to the air surrounding them.
Air Cooler Thermal Design. The air side heat transfer coefficient is usually the Briggs and Young correlation. It is from a "Chem. Eng. Prog. Symp. Ser. 59"., 1963. You have to be careful and not apply this equation equally to imbedded fins and tension wrapped fins. There is a contact resistance that has to be evaluated for the tension wrapped fins.
defined as dry air at 70 °F and 14.7 P.S.I.A. (29.92 in. mercury column). They can, however, be used in most cooling calculations unless extremely precise results are desired.
PMI Evaporative Cooling Sizing Calculator. Use the Calculator below to determine the appropriate cooler sizing based on your needs. Start by selecting the a geographic location the cooler will be used in and then cooler model. Refine your configuration by adjusting Static Pressure, Desired Indoor Temperature, Air Change Method and ceiling height. The resulted will appear to the right.
Air Cooled Heat Exchanger Sizing does preliminary estimation of Finned Area, Plot Size, Total Fan Power and Air Outlet Temperature CheCalc Chemical engineering calculations to assist process, plant operation and maintenance engineers.

Assuming efficiency AHP is the power required to move a given air volume against a given pressure. dpinWG = total pressure (in. Brake Horse Power - BHP. Brake horse power - the actual power a fan requires because no fan is efficient.
