WebThis implies that free energy is a linear function of temperature. Combining the above two equations: -RTlnK eq = ΔHº – TΔSº. Remember that the enthalpy and entropy changes are regarded as constants with respect to temperature, so the equilibrium constant is exponentially dependent on temperature. Rearranging the above equation gives: WebNov 4, 2024 · Enthalpy-Based Free Cooling System. Outdoor air is a mixture of water vapor and dry air which takes more energy to cool down than dry air. Additionally moist air will make the occupants uncomfortable and can cause mold. Enthalpy-based sensing uses both a temperature and humidity sensor to make the free cooling decisions. The …
WebFree Cooling and Low Energy Systems. Free cooling take place when the external ambient air enthalpy (the term used for a combination of sensible heat and moisture content) is less than the indoor air enthalpy and the cool external air is transferred to the building envelope either directly or indirectly.
