What is the sensible heat formula?

The sensible heat formula calculates the heat transfer involved in raising or lowering the temperature of air without changing its moisture content. The correct formula is BTU = CFM x 1.08 x Temperature Differential.

In this formula, CFM stands for Cubic Feet per Minute and refers to the airflow rate. The factor of 1.08 is derived from the properties of air, representing the amount of heat carried by 1 cubic foot of air when the temperature changes by 1 degree Fahrenheit. The Temperature Differential is the difference between the inlet and outlet temperatures of the air. This formula is crucial for determining how much heating or cooling is required to maintain comfort levels in HVAC applications.

Understanding the relationship expressed in this formula is critical for HVAC technicians, as it allows them to assess system performance effectively and make informed decisions regarding equipment sizing and energy consumption.
