Subjective thermal sensation and human body exergy consumption rate: analysis and correlation
Abstract
The exergy approach to design and operation of climate conditioning systems is relatively well established, while its exploitation in connection to human perception of the indoor environment is relatively rare. As a building should provide healthy and comfortable environment for its occupants, it is reasonable to consider both the exergy flows in building and those within the human body. There is a need to verify the human-body exergy model with the Thermal-Sensation (TS) response of subjects exposed to different combinations of indoor climate parameters (temperature, humidity, etc.). First results available on the relation between human-body exergy consumption rates and subjectively assessed thermal sensation showed that the minimum human body exergy consumption rate is associated with thermal sensation votes close to thermal neutrality, tending to slightly cool side of thermal sensation. By applying the exergy concept to the built indoor environment, additional results are going to be explored. By using the data available so far of operative temperature (to), the human body exergy consumption rates increase as to increases above 24°C or decreases below 22°C at relative humidity (RH) lower than 50%. While, at 85% of RH, the human-body exergy consumption rates decrease when to is increasing above 24 °C.
