FIELD: air conditioning equipment. SUBSTANCE: process complex has conditioned premise with baffle-type grids and air distributor, electric fan, dust filter, activated charcoal filter, electrostatic filter, carbon monoxide and hydrogen combustion unit, special gas filter, carbon dioxide absorbing unit, humidifier, and air heater. Carbon dioxide absorbing unit is made in the form of cryogenic system. Process complex is further equipped with absorber, cryogenic Stirling machine, liquefied air drain line, heat-insulated liquefied air storage vessel, line adapted for supplying liquefied air to absorber and provided with high-pressure pump and back valve which are part of cryogenic system, first and second regenerative heat-exchangers arranged upstream and downstream of carbon monoxide and hydrogen combustion system, respectively, and clean gaseous air line equipped with humidifier and adapted for connecting absorber to premise to be conditioned. Clean gaseous air line is extending through second regenerative heat-exchanger. Cooling circuit for cryogenic Stirling machine extending through air heater has pump and heat-exchanger. Cooling process water main is extending through heat-exchanger. EFFECT: increased efficiency, low weight and sizes, reduced consumption of power for air purification. 1 dwg
