Axial-flow blower arrangement


An axial-flow blower arrangement for the condenser (28) of a roof-mounted air conditioning installation including two evaporator units (3, 4) and a condenser unit (2) arranged between them comprises at least two blower modules (1), each of which has a box-shaped downwardly open hood (10) which has a cover wall (12) and walls (14, 15, 16, 17) which in the mounted condition extend downwardly from the cover wall and which together with the cover wall enclose an air suction chamber (26), out of which an axial-flow blower (23) mounted under the cover wall sucks air and discharges it into the atmosphere through an air outlet opening (20). The walls of the air suction chamber of each blower module extend in the mounted condition so far downwardly to the horizontally lying condenser (28) which completely covers over the open underside of the hood (10) and so terminate with the condenser that under the action of the axial-flow blower only air which has previously passed through the condenser can pass into the air suction chamber of the blower module..
