MULTI-PURPOSE AIR CONDITIONING SYSTEM OF SUPPLY AIR WITH HYBRID HOT AIR EXTRACTION LINE Russian patent published in 2018 - IPC F24F5/00 F24F7/00 F24F12/00 

FIELD: ventilation.

SUBSTANCE: claimed solution relates to air conditioning systems for supply air for maintenance of public buildings. Air conditioning system for supply air with the hybrid hot air extraction line comprises an air conditioner, an outdoor air intake fan, main fan for extraction of air exhausted from a room, a fan for extraction of hot air, a controller, an adsorption rotary regenerator, a rotary heat exchanger. Air conditioning system of supply air comprises a inlet air duct of air exhausted from the room and an air distribution unit of exhaust air exhausted from a room in the air conditioner, a hybrid hot air extraction line comprises inlet and outlet air ducts, adsorption rotary regenerator comprises an inverter and is built into an additional rotor channel of the horizontal intermediate partition of the air conditioner, and the rotary heat exchanger is built into the main rotor channel of the horizontal intermediate partition. Air distribution unit comprises a suction duct, main and additional fans for extraction of air exhausted from a room, a variable cross section pressure duct containing at least two distributing tees of different capacity, inlet duct of the hybrid hot air extraction line is made with a variable cross-section, comprises at least two collecting tees of different capacity, air conditioning system of supply air further comprises a supply air cooler with inlet and outlet nozzles, terminal unit of temperature of supply air and air exhausted from a room, the inlet air duct of air exhausted from a room comprises distributing and collecting tees of air exhausted from a room built thereinto, wherein the total mass flow of air exhausted from a room, distributed through the distribution ducts, being equal to the difference in the mass flow rates of the air exhausted from a room at the inlet and outlet of the pressure duct of the air distribution unit, and the mass flow of air exhausted from a room at the outlet of the pressure duct being equal to the mass flow of hot air at the inlet to the air conditioning system, providing mixing of hot air and exhaust air exhausted from a room in the air conditioner, in the collecting tees of the inlet duct of the hybrid hot air extraction line to obtain the required range of temperature change of the mixed air at the inlet to the additional exhaust chamber of the air conditioner and a sixteenfold increase in its mass flow as compared to the mass flow of hot air at the inlet to the air-conditioning system.

EFFECT: expanded functionality of the air conditioning system.
