In order to more clearly illustrate the control method provided by the embodiment of the present invention, a specific control example is provided below, and the specific control steps are shown in fig. 4:
after the unit is electrified and initialized and started, the dual systems normally operate. If the first outer fan is detected to be out of order and the second outer fan is not out of order in the operation process, the first outer fan is closed first, and the other load working states of the system corresponding to the first outer fan are kept. And simultaneously, opening a partition air valve port and operating the second outer fan to the highest load state. The second outer fan can be utilized to exhaust heat of the first heat exchanger and the second heat exchanger together, so that the system corresponding to the first outer fan can still keep refrigerating operation. If the first outer fan is still in fault after a certain time, the second outer fan is recovered to be in a normal load state, and the partition plate air valve port is closed. And simultaneously, immediately closing all loads of the system corresponding to the first outer fan, stopping the system corresponding to the first outer fan, and displaying or reporting a system fault indication corresponding to the first outer fan. When detecting that the first outer fan has no fault, controlling the first outer fan to normally operate; then the second outer fan is restored to the normal load state, and the partition plate air valve port is closed. When the second outer fan radiates heat for the first heat exchanger, if other faults occur in the system corresponding to the first fan, the second outer fan is restored to operate to a normal load state, the partition plate air valve port is closed, all loads of the system corresponding to the first outer fan are immediately closed, the system corresponding to the first outer fan stops operating, and a system fault indication corresponding to the first outer fan is displayed or reported.
Similarly, if the first outer fan is detected to be out of order and the second outer fan is detected to be out of order, the control steps are similar to the control steps. And will not be described in detail herein.
And if the first outer fan and the second outer fan are both detected to be in fault, immediately closing all loads of the double-system unit, stopping the double-system unit, and displaying or reporting a double-system fault indication.
The control method provided by the embodiment of the invention can maintain the operation of the whole system when one external fan fails; when the fault time length of the fan out of the fault is detected to be longer than the preset time length, the fan out of the fault still does not normally operate, the system corresponding to the fan out of the fault stops operating, the switch assembly is closed, and the fan out of the fault restores to a normal load state; when the fault duration is not longer than the preset duration, after the fault fan is recovered to be normal, the fault fan is controlled to normally operate, the switch assembly is closed, and the fault fan is not recovered to be in a normal load state. When the fault duration is not greater than the preset duration, detecting that other faults occur in the system corresponding to the fault fan, stopping the system corresponding to the fan out of the fault, closing the switch assembly, and recovering the normal load state of the fan without the fault. By the control method, the normal operation of the one-driving-two air conditioner can be ensured, and the situation that the refrigerating capacity is greatly reduced and the important heating equipment cannot be rapidly cooled is avoided.
