The claimed solution relates to the field of air conditioning systems for supplying air to the premises of public buildings. The air conditioning system contains a hot air exhaust line having a temperature of t ₁₂ = 40 ° C at the inlet of the line, providing the use of hot air for conditioning the supply air in a two-rotor air conditioner to obtain the set supply air parameters in the warm season.

In the hot air line of the inventive supply air conditioning system, two types of hot air can be used:

- Heated by the exhaust gases from the furnaces of boiler rooms to a temperature of t ₁₂ = 40 ° C, external or removed from the room air;

- exhaust gases purified from mechanical impurities from boiler furnaces having a temperature of t ₁₂ = 40 ° C.
