- A building or room gains heat from many sources. Inside occupants, computers, copiers, machinery, and lighting all produce heat. Warm air from outside enters through open doors and windows, or as ‘leakage’ though the structure. However the biggest source of heat is solar radiation from the sun, beating down on the roof and walls, and pouring through the windows, heating internal surfaces.
- The sum of all these heat sources is known as the heat gain (or heat load) of the building, and is expressed either in BTU (British Thermal Units) or Kw
- For an air conditioner to cool a room or building its output must be greater than the heat gain. It is important before purchasing an air conditioner that a heat load calculation is performed to ensure it is big enough for the intended application.
- There are several different methods of calculating the heat load for a given area. The heat gain of a room or building depends on the size of the area being cooled, the size and position of windows and whether they have shading, the number of occupants, heat generated by equipment and machinery and heat generated by lighting.
- Using XactRate’s heat load calculator you can accurately estimate the heat gain or heat load of a particular building. Manually calculating the heat load to determine the size of the air conditioner is a complicated task. XactRate’s heat load calculator makes this easier and completely automated, and therefore takes the guesswork out of the entire process.
