Analysis of working conditions

To analyze the adequacy of natural lighting give the room a scheme for the calculation shown in Figure 4.2. The normalized value of the coefficient of natural light (PAC) for the fourth light zone in which Ukraine is determined by the actual value of air As far exceeds standard value for both winter and summer, natural ventilation (aeration) is ineffective. Therefore, to increase the effectiveness of ventilation in the room, additional measures. In assessing the weather conditions in the test room to compare the actual values ​​of microclimate parameters: air temperature, relative humidity, air speed, the intensity of thermal radiation in the presence of his sources in a room with normative values ​​established by SDS 3.3.6.042-99. The actual values ​​can be obtained by direct measurement or use of hand-finished measurements, if they are in sanitary passports examined the premises. The rate of movement of the air, in addition, can be found from (4.6) if the area that will move the air quantity to a vertical cross-sectional area of ​​the investigated areas.
