ANALYSIS

L.L. Goshka
Climate system: the transition from a sanitary to physiological norms

In the article the system of standarts for ventilation systems design is analyzed. Present hygiene and sanitary standarts are based on sensory reactions. The author shows that these standarts don't guarantee tha health of users. He proposes to turn to standarts based on the human phisiology and calculation of carbonic gas permissible concentration.
