PROBLEM TO BE SOLVED: To provide a method for processing ventilation surrounding atmosphere in which heat is effectively utilized, an expenditure of facility and an operating expenditure of an air conditioning system are reduced. SOLUTION: An air conditioning system has a vapor pipe pit 22 storing vapor pipes 20a, 20b connected to an air conditioning boiler 16. An inner part of the vapor pipe pit 22 is divided into an upper section and a lower section, wherein the upper section is provided with a first air passage 32 and the lower section is provided with a second air passage 34, respectively. An end part of the first air passage 32 facing at the air conditioning boiler 16 and an end part of the second air passage 34 facing at the air conditioning boiler 16 communicate with each other. Surrounding atmosphere is fed into the first air passage 32 and flowed in the first air passage 32, the communicating part 33 and the second air passage 34 in the vapor piping pit 22. The surrounding atmosphere is heated with the generated from vapor pipes 22a, 22b while the surrounding atmosphere passes and then the heated surrounding atmosphere is supplied into a building 10 as ventilation surrounding atmosphere. |
