Embodiment 1
[0026] In order to ensure the air volume requirements of different cooling units for the existing ducted fan products that can switch the air outlet direction, different products will use different numbers of internal fans. When the unit needs to switch the air outlet direction, the conventional control method is as follows:
[0027] 1) The unit generates an air outlet switching requirement according to the control logic;
[0028] 2) Unit shutdown;
[0029] 3) The controller controls multiple internal fans to reversing together;
[0030] 4) After the commutation is completed, if the unit meets the shutdown and restart conditions (including the temperature point and the 3min shutdown time of the compressor), the unit will be restarted.
[0031] The specific process is as figure 1 As shown, the method includes the following steps S102-S112:
[0032] S102: The unit generates a demand for switching the upper and lower air outlets;
[0033] S104: stop the unit;
[0034] S106:...
Embodiment 2
[0064] Based on the air-conditioning control method provided in the above-mentioned embodiment 1, an air-conditioning control device is also provided in preferred embodiment 2 of the present invention, the air-conditioning includes multiple internal fans, specifically, Figure 4 shows an optional structural block diagram of the device, such as Figure 4 As shown, the device includes:
[0065] A detection module 402, configured to detect whether there is a reversing demand for the air conditioner;
[0066] The reversing module 404 is connected with the detection module 402, and if so, controls a plurality of internal fans to stop and reversing in accordance with the reversing order;
[0067] The starting module 406 is connected with the reversing module 404, and is used for controlling multiple internal fans to start up according to the starting sequence after the last internal fan in the reversing sequence stops.
[0068] In the above embodiment, an air conditioner control s...
Embodiment 3
[0078] Based on the air-conditioning control device provided in the above-mentioned embodiment 2, an air-conditioning unit is also provided in preferred embodiment 3 of the present invention, including the above-mentioned air-conditioning control device.
[0079] In the above embodiment, an air conditioner control scheme is provided for reversing without stopping. By detecting whether there is a reversing demand for the air conditioner, when the internal fans need to be reversed, multiple indoor fans are controlled to stop and switch in accordance with the reversing order. direction, and after the last internal fan in the reversing sequence stops, control multiple internal fans to start up according to the starting sequence. Through the above scheme, the internal fan can be reversed at different times to ensure the operation of the internal fan, so as to avoid the problem that the unit stops when the air outlet direction is switched, which affects the user's comfort, realizes s...
