ventilation when dealing with heat


Warehouses bulk materials

The chemical industry raw material storage and finished goods are usually not heated and ventilated. At the same time every now and stores bulk materials (eg, warehouse super-phosphate) are premises with abundant dusty. In these areas people are working at times continuously during the shift. Therefore, leave the premises of warehouses street... read more >>

Ventilation under the joint allocation of heat and moisture

With considerable heat haze - education is not observed. In some areas of the premises where the specific heat for some reason reduced the ability of local fog formation. In such cases, the zone of low heat release should be considered in isolation from the rest of the room. Ventilation of the "cold" zones is solved on the basis of anti-fog... read more >>

ventilation when dealing with heat

Heat in its pure form, ie not accompanied by other hazards, although rare, but occur. An example is the pump room by compressor, machine rooms, mechanical and extrusion mills in operation without an emulsion, etc.

The so-called hot shops are characterized by heat, which is accompanied gassing, and sometimes dust emission. Wet mills... read more >>

ventilation when dealing with moisture

As a rule, vlagovydeleniya accompanied by heat. However, if the allocation of water is relatively high, and the related heat dissipation are negligible, we can assume that there is a net vlagovydelenie. These cases include, for example, the allocation of water vapor with large surfaces at low temperature, the pair breaks into the room, drying... read more >>


Vlagovydeleniya in the air of industrial premises occur mainly as follows:

directly into the room;

with the air more humid than the indoor air (including people with breathing);
from open water surfaces or wetted materials due to their own heat or by heat supplied from outside;

with boiling water;

with cold surfaces...
