SUPPLY AIR CONDITIONING UNIT WITH HOT AIR LINE AND CASCADE HEAT RECOVERY Russian patent published in 2018 - IPC F24F7/00 F24F12/00 F24F13/00 

FIELD: ventilation.

SUBSTANCE: invention relates to the field of air conditioning systems for supply air for maintenance of public buildings. Supply air conditioning system with a hot air line, comprising an air conditioner and a hot air line, in addition, there are at least four air conditioners, one temperature adjuster of supply and exhaust air and one supply air cooler, hot air line contains at least three intermediate air ducts, rotary recuperators-heat exchangers of air conditioners are built in the main rotor channels of horizontal partitions, adsorption rotary regenerators are built into additional rotor channels of horizontal partitions. Air conditioners are made by two-rotor and three-rotor. Supply air conditioning units of are installed in pairs in the opposite direction to the inlet nozzles of the main exhaust chambers and the outlet nozzles of the supply chambers and are arranged in two rows, with maintenance of work in technically achievable range of efficiency of heat recovery and formation of required cooling of supply air in the warm period of the year in the air conditioning system of supply air at the temperature of hot air at the entrance to the additional exhaust chamber of the two-rotor air conditioning system of the supply air conditioning no more than 40 °C and temperature drops of hot air at the entrances and exits of additional exhaust chambers of three-rotary air conditioners of the air conditioning system of supply air not exceeding 20 °C, providing deep utilization of heat of hot air.

EFFECT: expansion of the functionality of the supply air conditioning system in the form of cooling supply air in the warm period of the year in the air conditioning system, and also to ensure the eight-fold use of hot air obtained by using waste gases from furnaces and drying units.
