Operation modes of local water evaporative air cooler cabins of self-propelled vehicles with regard to individual operators and variability of temperature conditions

The possibility of efficient use of local air cooler in cabins as a means of normalization of the thermal state of opera- tors with regard to their sex, weight and changing environment of air temperature during the day is considered. It is shown that for the assimilation of different heat generation levels of maximum possible number of operators the per-formance of device over the air must have infinitely variable adjustment. At the same time, it is shown that external temperature changing does not require air supply regulation. The degree of cooling air in apparatus irrigated nozzle re- tains constant throughout the whole range of initial temperature and air flow variation.
