AIR CONDITIONING PLANT Russian patent published in 2019 - IPC F24F12/00 F24F7/00 

FIELD: ventilation.

SUBSTANCE: invention relates to mechanical ventilation systems providing for indirect evaporation cooling of inlet air. Air conditioning installation includes air supply air valves and exhaust air valves connected to air filters, adiabatic humidifier, air heater in lower installation tier, as well as plate heat exchanger, at the same time intermediate sections are additionally introduced in upper tier of installation after air filter, before plate heat exchanger and in lower tier of plant after plate heat exchanger in front of fan section, wherein intermediate sections at level of each tier are connected to each other by control valves on vertical panels, intermediate section of upper tier directly adjacent to air filter is connected to intermediate section of lower tier, directly adjacent to plate heat exchanger, bypass with control valve, and intermediate section of upper tier adjacent to plate heat exchanger is connected to intermediate section of lower tier, adjacent to fan section, through control bypass valve, in addition, additionally introduced are intermediate sections in upper tier of plant after air filter in front of plate heat exchanger and in lower tier of plant after adiabatic humidifier in front of fan section, wherein intermediate sections at level of each tier are connected to each other by control valves on vertical panels, intermediate section of upper tier directly adjacent to air filter, is connected to intermediate section of lower tier immediately adjacent to adiabatic humidifier, through control bypass valve, and intermediate section of upper tier, adjacent to plate heat exchanger, is connected to intermediate section of lower tier, adjacent to fan section, bypass with control valve.

EFFECT: method makes it possible to use the air conditioning unit throughout the whole year using one adiabatic humidification section.
