A correct enthalpy relationship as thermal comfort index for livestock

Abstract: Researchers working with thermal comfort have been using enthalpy to measure thermal energy inside rural facilities, establishing indicator values for many situations of thermal comfort and heat stress. This variable turned out to be helpful in analyzing thermal exchange in livestock systems. The animals are exposed to an environment which is decisive for the thermoregulatory process, and, consequently, the reactions reflect states of thermal comfort or heat stress, the last being responsable for problems of s… Show more

“…1) proposed by Rodrigues et al (2010): fiber tile showed little variation with respect to enthalpy. The maximum mean enthalpy values between the roofing materials, were of 62.5, 62.5 and 63.0 kJ kg -1 dry air for the shelters covered with recycled tile, thatched roof and cement fiber tile, respectively, at 11 h. The minimum mean enthalpy values between the roofing materials, with values of 52.5, 53.5 and 52.5 kJ kg -1 dry air for the shelters covered with recycled tile, thatched roof and cement fiber tile, respectively, at 4 h (Figure 1).…”
