In order to use the heat load calculations some general definitions need to be addressed. The calculations will reference the following basic definitions and formulas: One Ton of Refrigeration = 12,000 Btu per Hour Windows Sensible Cooling Load Calculation. The sensible cooling load of windows is calculated by multiplying the area of the windows by the glass load factor (GLF). The formula used is as follow: q = Aw(GLF) where, q = sensible cooling load, W. A = area of window, m2. GLF = glass load factor, W/m2.

Título original: heat load calculation manual.pdf. Cargado por Mohammed Jassim. Descripción: heat load manual. Cooling load calculation methodologies take into account heat transfer by conduction, convection, and radiation. Methodologies include heat balance, radiant time series [12] cooling load temperature night; therefore, in determining the heating load, credit for heat generation from internal heat sources such as lights, machinery, appliances, and people is usually ignored. Also in determining the heating load, credit for solar heat gain is usually NOT included and is generally ignored. Credit for solar heat gain is a plus factor in winter Examples of Heat Load Calculation. Here are some of the examples that explain how to calculate heat load using the heat load calculation formula. Example 1. Calculate the heat load of an electric convertor whose mass flow rate is 6.75 and the specific heat of the system is 1000 and the enthalpy ranges from 21.5 to 26.55. Solution- heat gain. Σ Using "conduction" WF coefficients calculate hourly cooling loads due t o conducti n heat gain and absorbed solar heat gain. Using "lighting" WF coefficients calculate hourly cooling loads due to lighting heat gain. Using "occupant/equipment" WF coefficients, calculate hourly cooling loads due to occupants and equipment. Heat Gain MAKING QUICK HEAT LOAD CALCULATIONS There may be times when you need to make a non-critical heat load calculation, either for basic cost-estimating purposes or for some other reason.Table 7 at the bottom of the next page will help you make a quick calculation of heat transmission through insu-lated walls. It lists the heat gain for various thick- methods of performing load calculations, or step-by-step instructions on how to perform the load calculations. This guide presents the key criteria required to create accurate heating and cooling load calculations and offers examples of the implications when inaccurate adjustments are applied to the HVAC design process.
