DEVICE FOR ENSURING OPERATION OF EXTERNAL BLOCKS OF FREON CLIMATIC SYSTEMS OPERATING IN COLD MODE WITH SUB-ZERO OUTSIDE AIR TEMPERATURES Russian patent published in 2018 - IPC F24F13/20 

FIELD: ventilation.

SUBSTANCE: invention relates to outdoor units of freon climate systems and is intended to ensure their uninterrupted operation at low outdoor temperatures in winter. Technical result is achieved by the fact that the proposed design of the device to ensure the operation of the outdoor units of freon climate systems with vertical or horizontal emission of hot air from the outdoor unit condenser with its axial fan (fans), consisting of a spatial frame, assembled from metal rectangular pipes, which is rigidly fixed on a foundation base, on the side and end sides of the internal volume of the spatial frame are fixed boxes for electric roller shutters, inside of which there are the shutters of the roller shutters, on top of the spatial frame there is a horizontally fixed air valve with a modulating electric drive, electronic control controller and two temperature sensors are installed inside the spatial frame of the device, one installed in the upper part and the other in the lower part of the internal volume of the device, and the outside temperature sensor is installed outside.

EFFECT: technical result of the invention is to ensure the operation of the device in a fully automatic mode by regulating the required amount of fresh air and without changing the direction of the air flow generated by the fan, that allows to use the proposed device for various types of outdoor units of freon climate systems.
