By calculating these various saturations we can determine the necessary airflows, entering and leaving air temperatures, and equipment loads of the zone. Divide the heat load by the cooling capacity of the air conditioning unit in BTU, to determine how many air conditioners are needed. Psychrometric calculations use thermodynamic properties to analyze conditions and processes involving moist air. Thus, the heat gain for a particular component at a particular hour is the same as 24 h prior, which is the same as 48 h prior, etc.ДЄfter collecting all of the cooling load components for each space, the heating load is calculated.

Downloads equipment selection is done with. Details about COOLING AND HEATING LOAD CALCULATION MANUAL By Faye C. Design cooling loads are based on the assumption of steady periodic conditions (i.e., the design day's weather, occupancy, and heat gain conditions are identical to those for preceding days such that the loads repeat on an identical 24 h cyclical basis). Manual J Load Calculations: Estimates are correct for the amount of heating and cooling required for a residence.
