Sensible heat is considered the measurement of which temperature?

Sensible heat refers to the heat that causes a change in temperature of a substance without changing its state (i.e., from solid to liquid, or liquid to gas). It can be measured by the increase or decrease in the temperature of air. The dry bulb temperature is the standard measure of air temperature using a thermometer that does not take humidity into account, making it the direct measurement of sensible heat.

When we assess the thermal comfort of a space or the performance of HVAC systems, the dry bulb temperature is often the reference point, as it provides an accurate representation of the thermal energy present in the air. Other temperature measures, like wet bulb, incorporate humidity and thus don’t solely reflect sensible heat. Therefore, dry bulb temperature is an essential concept in HVAC when assessing thermal loads, comfort levels, and system efficiencies.
