The heating load is the quantity of heat energy that must be added to an area in order to maintain a comfortable temperature. The cooling load is the quantity of heat energy that must be evacuated from a room (cooling) in order to maintain a comfortable temperature.
Sensible and latent heat loads are the two forms of heat loads. Humans, fans, lamps, heaters, electric presses, and other sources are among the different sources. Friction, temperature rise from combustion, and fuels are all examples of heat sources.
The heating load is the amount of heat energy that must be provided to a specific location in order to maintain a comfortable temperature. The cooling load is the amount of heat energy that must be drained from space in order to maintain a comfortable temperature.
BTUs (British Thermal Units) are used to assess heat load (British thermal units). The amount of energy necessary to heat or cool a single pound of water by one degree is specified as one BTU, which is about 1055 joules.
Heat load (BTU) = Length (m) x Width (m) x Height (m) x 141. So, for a room measuring 5m x 4m x 3m = 60 > x 141 = 8,460 BTU. (For measurements in feet, the formula becomes: Heat load (BTU) = Length (m) x Width (m) x Height (m) x 4)
