This new edition of Load Calculation Applications Manual presents two methods for calculating design cooling loads—the heat balance method (HBM) and the radiant time series method (RTSM)—in a thorough, applications-oriented approach that
Our free, easy-to-use HVAC load calculator will help you determine the necessary thermal output capacity (in BTUs) of any residential building.
Learning Objectives. Understand when a Manual J load calculation should be performed. Understand how to look up information for a Manual J calculation. Understand common mistakes made in Manual J entries. Understand how to use Manual J software packages for detailed load calculations.
Calculations are performed per ACCA Manual J 8th Edition, Version 2, and ACCA Manual D. All computed results are estimates as building use and weather may vary. Be sure to select a unit that meets both sensible and latent loads according to the manufacturer's performance data at
Cooling & heating load calculations are normally made to size HVAC (heating, ventilating, and air-conditioning) systems and their components. In principle, the loads are calculated to maintain the indoor design conditions.
