SUPPLY AIR CONDITIONING SYSTEM WITH HOT AIR DRAFTING LINE Russian patent published in 2018 - IPC F24F5/00 F24F7/00 F24F12/00 

FIELD: ventilation.

SUBSTANCE: claimed solution relates to the field of air conditioning systems for supply air for maintenance of public buildings. Supply air conditioning system contains air conditioners and a hot air drafting line. Air conditioner contains a supply chamber and a main exhaust chamber, an adsorption rotary regenerator and a rotary heat exchanger with heat exchangers having oppositely directed inflow and outflow lines. Air conditioners are arranged in a row towards the inlet nozzles of the main exhaust chambers and the outlet nozzles of the supply chambers with the connection of the inlet pipes of the main air-conditioning chambers with the distributing tee of the air removed from the room and outlet nozzles of the inlet chambers with a supply air collecting tee joint. Hot air drafting line contains a heat-insulated intermediate air duct, the inlet duct of the hot-air drawing line at the outlet is connected to the inlet branch of the additional exhaust chamber of the three-rotor air conditioner, the heat-insulated intermediate air duct of the hot air drafting line is connected at the inlet with the outlet pipe of the additional exhaust chamber of the three-rotor air conditioner and at the outlet with the inlet branch of the additional exhaust chamber of the two-rotor air conditioner. Exhaust outlet of the additional exhaust chamber of the two-rotor air conditioner is connected to the exhaust duct of the additional hot-air drafting line of the air conditioning system.

EFFECT: ensuring zero energy consumption for heating the supply air during the cold season in two air conditioning units of the supply air conditioning system without freezing the rotors of adsorption rotary regenerators of air conditioners and the stability of obtaining specified parameters of conditioned supply air with deep utilization of hot air heat.
