Abstract (en)
[origin: CN207050304U] The utility model relates to a ventilation unit for refrigeration plant (1), its design be used for the installation with arrange refrigeration plant department and the fan has and with fan tandem arrangement's heat exchanger (3), wherein fan design and arranging for heat exchanger (3) do, pass heat exchanger (3) and leave ventilation unit at conveying air flow in service, its characterized in that, the fan design is for inclined flow type fan (2) and inhale air mass flow and discharge along the slant with the angle for its rotation axis (RA) along the axial in service. According to the utility model discloses a ventilation unit can be more high -efficient ground and moving with littleer defrosting frequency.
