Modern approaches to the substantiation of comfort parameters of the microclimate and rooms are mainly focused on the requirements of State Standart ГOCT P ИCO 7730 and ASHRAE Standard 55. The article describes a method for calculating the dependencies of the required air temperature on mobility, mobility and radiation temperature difference at various levels of metabolism and insulation of clothing for three classes comfort. For each class of comfort pre-built tables of iso-comfort microclimatic parameters, which are calculated for different levels of human metabolism and clothing characteristics. The obtained values from the tables of iso-comfort microclimatic parameters are substituted into the empirically derived equation for calculating the equivalent temperature. The results in the form of the equivalent comfortable temperature are approximated as a function of the level of metabolism and the characteristics of the clothes, as a result of which generalized calculated expressions of the parameter of the equivalent comfortable temperature are obtained. The results in the form of the equivalent comfortable temperature are approximated as a function of the level of metabolism and the characteristics of the clothes, as a result of which generalized calculated expressions of the parameter of the equivalent comfortable temperature are obtained. Thus, six data arrays with thermal comfort parameters for rooms of three classes are summarized by six calculated algebraic expressions. The obtained calculated expressions of equivalent comfortable temperature can be used in the design of air conditioning systems and in programming automatic climate control systems.
