Abstract
Self-propelled agricultural machinery is mainly utilized during the warm period of the year. Under such conditions, due to solar radiation and other heat sources, inside conditions of operator's cab could become detrimental. Therefore, generating and maintaining of comfortable microclimate is very important aspect of ergonomics in the machinery cab. Conventional approach for cab microclimate conditions analyze is based on the presumption that there is homogenous state. Standards for indoor microclimate conditions also recommend minimal non-homogeneity. In reality, the conditions are usually non-homogenous and transient, but human body occupies only minor part of total cab interior volume and there are no much possibility for change the postures. Beside of this, individual parts of the body have different thermal sensitivity and different influence on overall thermal sensation and thermal comfort. This fact was used in this paper as a basis for research in field of non-uniformity of microclimate parameters in tractor cab by localized distribution of conditioned air.
