摘要
FIELD: technology for measuring and evaluating microclimate.;SUBSTANCE: method for measuring and hygienically evaluating microclimate includes measuring, with closed doors and windows, open shutters or curtains and microclimate maintenance system working in automatic stationary mode, of outer air temperature and air temperature in the center of first, middle and last compartments of passenger car, in the middle and at the ends of its corridor in three vertically arranged points at levels of 0,1 m, 1,2 m and 1,7 m from the floor, and also at the beginning, in the middle and the end of the salon in two vertically arranged points at levels of 0,1 m and 1,2 m from the floor. The average temperature measured in passenger car is derived from a formula. Relative humidity is measured at the level of 1,2 m from the floor in the center of first, middle and last compartments, in the center and at ends of salon, resulting relative humidity characteristics are averaged. Air movement speed is measured at the level of 0,1 m, 1,2 m and 1,7 m from the floor in the center of first, middle and last compartments, in the middle and at ends of corridor, and also in the center of salon at the level of 0,1 m and 1,2 m from the floor at the beginning, in the middle and at the end of salon, and resulting air movement speed characteristics are averaged. Boundary surface temperatures are measured at the level of 0,4 m from the floor of a settee or a shelf in the first, middle or last compartment, and also in the corridor in front of passenger car compartment, at the level of 0,4 m from the settee, wall or window at the beginning, middle or end of salon, and average radiation temperature measured on boundary surfaces is derived from a formula. Alignment chart is used to determine the resulting temperature value for measured values of microclimate parameters. Resulting temperature value is compared to standard value for a certain climate zone to evaluate the operation of microclimate control system.;EFFECT: increased precision and reliability.;5 cl, 1 dwg, 4 ex
