What does ΔT represent in the thermal load formula?

ΔT represents the temperature difference in the thermal load formula, which is crucial in calculating heating and cooling requirements for a building or space. This parameter reflects the difference between the desired indoor temperature and the outdoor or ambient temperature.

Understanding ΔT is essential for HVAC professionals because it helps determine how much heating or cooling is necessary to maintain a comfortable environment within a space. For instance, a higher ΔT indicates that more energy will be needed to either heat or cool a space effectively, as there is a larger gap between the outside and inside temperatures.

In practice, accurately calculating ΔT allows for the efficient design and operation of HVAC systems, ensuring that they can adequately handle the thermal loads throughout different seasons and conditions.
