Title:
OUTSIDE INSTALLATION TYPE COOLING UNIT
Document Type and Number:
Japanese Patent JP2004012099
Kind Code:
A
Abstract:
To prevent failure of a controller due to generated voltage of a motor operating as a generator.
The outside installation type cooling unit is provided with a plurality of motors MA and MB mutually parallel-connected in an output side of the controller 50 and capable of operating the generator, fans FA and FB respectively connected to rotors of the motors, and heat exchangers 110 arranged in ventilation paths of the fans. Wind directions 401 and 402 with respect to the heat exchanger 110 by each fan FA and FB during normal operation are varied so that the generated voltages of the motors MA and MB generated when each fan FA and FB is forcibly rotated by wind force in a single direction from the outside cancel each other out.
