AIR CONDITIONING SYSTEM WITH A HYBRID HOT AIR EXHAUST LINE Russian patent published in 2018 - IPC F24F5/00 F24F7/00 F24F12/00 

FIELD: air conditioning systems.

SUBSTANCE: invention relates to the field of air conditioning systems for supply air for maintenance of public buildings. Supply air conditioning system with a hybrid hot air extraction line contains air conditioning, an inflow fan, an exhaust fan, a hot air extract fan, the air conditioner contains a supply chamber and a main exhaust chamber, separated by a horizontal partition with rotor channels, an adsorption rotor regenerator and a rotor heat exchanger-heat exchanger built into the rotor channels, the adsorption rotary regenerator has oppositely directed supply and exhaust lines, the rotary heat exchanger has an inflow line, in addition, the air conditioner contains an additional extract air chamber of hot air. New is the fact that the system contains an air distribution unit and a hot air temperature closer with a rotary heat exchanger. Additional exhaust chamber of hot air is placed above the horizontal intermediate partition of the air conditioner with a rotor heat exchanger that has a hybrid hot air extraction line opposite to the inflow line. Air distribution unit contains a suction duct, a pressure duct containing two dispensing tees, an exhaust air exhaust fan, an additional exhaust fan, the intake air duct is connected to the outlet of the main exhaust chamber of the air conditioner and to the suction inlet of the exhaust fan; the discharge nozzle is connected to the pressure air duct of the air distribution unit, inlet duct of the hybrid hot-air extraction line is made with a variable cross-section and contains two collecting tees, distributing and collecting tees are pairwise interconnected by distributing ducts, hot air temperature closer contains a hot air inlet chamber and exhaust air exhaust chamber separated by a horizontal partition with a rotor channel, a rotary heat exchanger built into the rotor channel, inlet duct of the hybrid hot air exhaust line is connected by a duct to the outlet of the inlet chamber of the hot air temperature closer and to the inlet of the additional exhaust chamber of the air conditioner, the discharge air duct of the air distribution unit is connected by a duct to the inlet port of the exhaust chamber of the hot air temperature closer, the exhaust pipe of which is connected by an air duct to the suction pipe of an additional exhaust fan of the air removed from the room, and the exhaust pipe of the additional exhaust chamber of the air conditioner is connected to the exhaust air pipe of a hybrid hot air exhaust line, which is connected to the intake duct of the hot air exhaust fan, the outlet of the inlet chamber of the air conditioner is connected to the air inlet duct of the outside air intake duct.

EFFECT: expanding the functionality of the supply air conditioning system in the form of ensuring zero energy consumption for heating the supply air in the cold period of the year.
