The inventive air conditioning air supply system provides supply air for public buildings with parameters in the warm season: temperature t ₇ = 20 ° C, moisture content d ₇ = 7.9 g / kg dry. air., relative humidity ϕ ₇ = 0.53.

The supply air conditioning system uses exhaust air entering the exhaust chambers of the air conditioners with parameters: temperature t ₁₀ = 22.1 ÷ 21 ° C, moisture content d ₁₀ = 8.9 g / kg dry. air

The specified exhaust air parameters are obtained in the inventive supply air conditioning system by treating the air removed from the room with parameters: temperature t ₈ = 23 ° C, relative humidity ϕ ₈ = 0.5 (in units) and moisture content d ₈ = 8.9 g / kg dry air in the closer of the temperature of the supply and exhaust air and the treatment of the supply air in the closer of the moisture content of the supply air when the temperature of the outside air changes during the warm season in the range t ₁ = 15 ÷ 30 ° C, relative humidity ϕ ₁ = 0.7 (in fractions of a unit) and moisture content in the range of d ₁ = 7.6 ÷ 19.1 g / kg dry. air
