Provided is an outdoor unit for a refrigeration device, the outdoor unit being configured so that, when the total amount of air supplied by the outdoor fans is reduced, a reduction in the total amount of air obtained by outdoor fans and passing through the outdoor heat exchanger is minimized. An outdoor unit for a refrigeration device is provided with: an outdoor heat exchanger (23); a first outdoor fan (28a) and a second outdoor fan (28b) which generate airflow passing through the outdoor heat exchanger (23); and a fan control unit. When a small amount of air is required, the fan control unit changes from a first operation state to a second operation state, the first operation state being a state in which the first outdoor fan (28a) and the second outdoor fan (28b) operate, the second operation state being a state in which the operation of the first outdoor fan (28a) is continued and the supply of electric power to the second outdoor fan (28b) is cut off. Also, after changing to the second operation state, the fan control unit performs fan on/off control for turning on and turning off the supply of electric power to both the first outdoor fan (28a) and the second outdoor fan (28b) on the basis of the monitoring of the values of electric currents relating to a timer and the fan motors or on the basis of the monitoring of the speed of the fans. |
