COOLING AGENT DISTRIBUTION SYSTEM FOR INDIRECT EVAPORATIVE COOLING DEVICE Russian patent published in 2020 - IPC F24F3/14 F28D9/00 

FIELD: ventilation and air conditioning.

SUBSTANCE: invention relates to a coolant distribution system used in indirect evaporative cooling devices with dry and wet channels. System comprises upper, middle and lower levels of coolant passage, first and second intermediate reservoirs with two inputs and two outputs, channels for air displacement and vessel with sensors. Upper level of coolant passage has bath, inlet and outlet, inlet channel, outlet channel, as well as inlet and outlet of first intermediate container. Average coolant flow rate has a bath, an inlet and an outlet, an inlet channel, an outlet channel connected in fluid communication with the channel for air displacement and a channel for air displacement through the inlet and outlet of the second intermediate reservoir. Lower level of coolant passage has bath, inlet and outlet, inlet channel, outlet channel, besides, inlet channel is connected with outlet channel via inlet and outlet of second intermediate reservoir, and with vessel with sensors, and outlet channel is connected to appropriate channel for air displacement.

EFFECT: this allows reliable and cheap cooling of air entering the room.
