It is a measure of the heat content of a substance. Change in heat content at constant pressure. Standard conditions (DH o ) = 100 kPa and a stated temperature.
Sensible Heat. The sensible heat in a heating or cooling process of air (heating or cooling capacity) can be calculated in SI-units as. h s = cpρ q dt (1) . where . h s = sensible heat (kW) . cp= specific heat of air (1.006 kJ/kg oC) . ρ = density of air (1.202 kg/m3) . q = air volume flow (m3/s) . dt = temperature difference (oC) .
Sensible heat is heat exchanged by a body or thermodynamic system in which the exchange of heat changes the temperature of the body or system, and some macroscopic variables of the body or system, but leaves unchanged certain other macroscopic variables of the body or system, such as volume or pressure.

When a material changes temperature, it absorbs or releases sensible heat. The amount of heat depends on the mass, material, and temperature change (Q = mc∆T).
Sensible heat is literally the heat that can be felt. It is the energy moving from one system to another that changes the temperature rather than changing its phase. For example, it warms water rather than melting ice.
Sensible heat is directly linked to specific heat as it quantifies the energy needed to change a substance's temperature without changing its phase. The relationship can be captured using the equation Q = mcΔT, where Q represents sensible heat.
7 gru 2022 · Sensible heat is the heat transferred to an object that results in a change in its temperature, with no accompanying change in phase. In HVAC systems, this heat is often referred to as the sensible load, and calculating it is necessary to forecast the system's characteristics to implement.
