摘要:
The invention relates to a method for regulating the atmosphere in a substantially closed sports/exercise space (1) or an animal shelter (11), especially in terms of partial oxygen pressure. In the method, the normal atmosphere of said space (1; 11) is admixed with nitrogen for the creation of a desired low-oxygen (oxygen content appr. 21%) atmosphere. Said mixing of nitrogen or oxygen with air is carried out at normal air pressure.
