EDDY EVAPORATIVE CONDENSER Russian patent published in 2005 - IPC

FIELD: compensation of refrigerant vapors in refrigerating plants.

SUBSTANCE: the eddy evaporative condenser has eddy heat exchangers in the form of large - diameter pipes with U-shaped ribs forming ducts for passage of refrigerant secured on the outer surface, axial-flow fans with profiled blades, nozzle fin with nozzles, circulating pump, filter, tray, drop separator and an outer guard. Eddy of air flow in the heat exchanger is effected by the axial-flow fan with profiled blades installed at angle ϕ=40°-65° between the generating line of the fan body and the tangent line to the blade at the air outlet hear the body wall. Eddy heat exchangers are made with a ribbing coefficient varying in accordance with relation: γ=πD/(nl)=1-5, where D - the pipe diameter; n-quantity of ducts; l-the duct width, which in turn vary within D=400-1000 mm; l -20-140 mm; the duct height l₁=20-60 mm; pipe wall thickness δ=3-6 mm; duct wall thickness, δ₁=2-4 mm, and pipe length L to diameter ratio D, L/D≤40.

EFFECT: reduced power and mass characteristics of the offered evaporative condenser.
