[0033] Reference below Figure 1-Figure 6 The air conditioning system and its control method according to the embodiment of the invention are described.
[0034] Such as Figure 1-Figure 6 As shown, the air conditioning system 100 according to the embodiment of the present invention includes an air conditioning outdoor unit 10 and an air conditioning indoor unit 20. The air conditioner outdoor unit 10 includes a compressor 11, an outdoor heat exchanger 12, and an outdoor fan 13. The outdoor fan 13 has at least a first working mode and a second working mode, and the outdoor fan has a high wind level when operating in the first working mode. The windshield when running in the second working mode.
[0035] The control method of the air conditioning system according to the embodiment of the present invention includes the following steps:
[0036] S1. Control the air conditioning system to enter the cooling mode;
[0037] S2. Control the outdoor fan to enter the first working mode or the second working mode according to the outdoor ambient temperature and/or the predetermined time.
[0038] In other words, the air-conditioning system can control the outdoor fan to enter different working modes according to the outdoor ambient temperature, and can also control the outdoor fan to operate in different working modes according to the different times of the day of the air-conditioning system. For example, the air-conditioning system can control the outdoor fan to operate in the first working mode during the day, and control the outdoor fan to operate in the second working mode at night, so that the windshield of the outdoor fan is lowered without affecting the user's rest.
[0039] According to the control method of the air conditioning system of the embodiment of the present invention, the air conditioning system can control the outdoor fan to enter the first working mode or the second working mode according to the outdoor ambient temperature and/or the predetermined time. When the outdoor fan is running in the second working mode, The reduction of the windshield of the outdoor fan will not affect the reliability of the air conditioning system. At the same time, it can reduce the operating noise of the outdoor unit and meet the requirements of user comfort.
[0040] Among them, in step S1, the air conditioning system is controlled to enter the cooling mode, and the outdoor fan is first controlled to operate in the first working mode, that is, when the air conditioning system is turned on, the outdoor fan first runs in the first working mode, and then according to the outdoor ambient temperature and/ Or at a predetermined time, control the outdoor fan to run in a specific working mode.
[0041] Such as figure 1 As shown, according to an optional embodiment of the present invention, step S2 includes:
[0042] S21. Detect the outdoor ambient temperature in real time, and control the working mode of the outdoor fan according to the detected outdoor ambient temperature;
[0043] S22. When the detected outdoor ambient temperature reaches the set maximum temperature Tmax, start timing;
[0044] S23: When the accumulated time reaches the first predetermined time t1, control the outdoor fan to enter the second working mode.
[0045] Further, after step S2, that is, after the outdoor fan enters the second working mode, the timer is restarted, and when the accumulated time reaches the second predetermined time t2, the outdoor fan is controlled to enter the first working mode.
[0046] Take the first working mode as the normal working mode of the outdoor fan, and the second working mode as the night working mode of the outdoor fan as an example. When the air conditioning system is cooling, the outdoor fan first runs at a normal speed, and the outdoor ambient temperature is detected in real time. When the detected outdoor ambient temperature reaches the set maximum temperature Tmax, the system defaults to this time from 12 noon to 14:00. And start the cumulative timing, when the cumulative timing time reaches the first predetermined time t1, the air conditioning system adjusts the working mode of the outdoor fan from the first working mode to the second working mode. At the same time, the accumulated timing is restarted, and when the accumulated timing time reaches the second predetermined time t2, the air conditioning system controls the working mode of the outdoor fan to be adjusted from the second working mode to the first working mode, and so on.
[0047] Because the outdoor ambient temperature at night is lower than the outdoor ambient temperature during the day, and the pressure of the air-conditioning system at night is lower than the pressure during the day, so when the outdoor fan runs in the second working mode (night working mode), the speed of the outdoor fan is reduced, It will not affect the reliability of the air-conditioning system, and at the same time, it can meet the comfort requirements of users without affecting users' rest.
[0048] It should be noted here that between 12 noon and 14 pm mentioned above, the outdoor ambient temperature can reach the set maximum temperature Tmax is obtained based on life experience. Of course, for outdoor temperatures in different regions, the corresponding time periods may be different, and the maximum temperature Tmax is also different. This can be understood by those skilled in the art, and users can make reasonable settings according to local conditions.
[0049] Such as figure 2 As shown, according to yet another optional embodiment of the present invention, step S2 includes:
[0050] S21. Detect the outdoor ambient temperature in real time, and control the working mode of the outdoor fan according to the detected outdoor ambient temperature;
[0051] S22: When the detected outdoor ambient temperature is lower than Tmin, control the outdoor fan to enter the second working mode.
[0052] Further, after step S2, that is, after the outdoor fan enters the second working mode, the timer is restarted, and when the accumulated time reaches the second predetermined time t2, the outdoor fan is controlled to enter the first working mode.
[0053] In other words, the working mode of the outdoor fan can be determined by the outdoor ambient temperature at night. Take the first working mode as the normal working mode of the outdoor fan, and the second working mode as the night working mode of the outdoor fan as an example. When the air conditioning system is cooling, the outdoor fan first runs at a normal speed, and the outdoor ambient temperature is detected in real time. When the detected outdoor ambient temperature reaches the set minimum temperature Tmin, the system defaults to night time, and the air conditioning system will The working mode is adjusted from the first working mode to the second working mode. At the same time, the cumulative timing is started, and when the cumulative timing time reaches the second predetermined time t2, the air conditioning system controls the working mode of the outdoor fan to be adjusted from the second working mode to the first working mode, and so on.
[0054] Such as image 3 As shown, according to another optional embodiment of the present invention, in step S2, the outdoor fan is controlled to enter the first working mode or the second working mode at a predetermined time. Specifically, clock detection can be added to the air-conditioning system. By detecting the time, the outdoor fan is controlled to operate in the second working mode at a set time (for example, set at 23 o'clock in the evening), so as to reduce the operating windshield of the outdoor fan to meet the user's requirements. Comfort requirements.
[0055] According to a further embodiment of the present invention, step S2 further includes: detecting the exhaust pressure of the outdoor unit of the air conditioner in real time; acquiring the windshield of the outdoor fan in the current working mode, and controlling the outdoor fan to operate corresponding to the windshield, which is convenient to control.
[0056] In some optional examples, when the outdoor fan enters the first working mode, the relationship between the detected exhaust pressure Pc and Pa and Pb is judged. If the exhaust pressure Pc Pb, the outdoor fan is controlled to upshift; if the exhaust pressure Pa≤Pc≤Pb, the outdoor fan is controlled to maintain the original wind gear.
[0057] In some specific examples, the air conditioning system adjusts the operating windshield of the outdoor fan in real time according to the exhaust pressure of the outdoor unit. When the outdoor fan is running in the first working mode (normal working mode), when the exhaust pressure Pc of the outdoor unit is lower than Pa, the speed of the outdoor fan is reduced by one gear. When the exhaust pressure Pc of the outdoor unit is higher than Pb, the outdoor fan's The rotation speed is increased by one gear. When the exhaust pressure of the outdoor unit is between Pa and Pb, the outdoor fan maintains the original windshield. By adjusting the windshield of the outdoor fan, the exhaust pressure Pc of the outdoor unit is maintained at a reasonable and reliable Within the range, that is, maintained between Pa and Pb.
[0058] Further, when the outdoor fan enters the second working mode (night working mode), the relationship between the detected exhaust pressure Pc and Paˊ, Pbˊ is judged. If the exhaust pressure Pc Pbˊ, the outdoor fan is controlled to upshift; if the exhaust pressure Paˊ≤Pc≤Pbˊ, the outdoor fan is controlled to maintain the original wind speed.
[0059] Among them, Paˊ>Pa, and Pbˊ>Pb. In other words, when the exhaust pressure of the outdoor unit at night decreases, the speed of the outdoor fan is easier to decrease, not easy to increase, so that the speed of the outdoor fan is maintained between Paˊ and Pbˊ.
[0060] As a result, the operating windshield of the outdoor fan can be adjusted in real time according to the outdoor ambient temperature and the exhaust pressure of the outdoor unit to realize automatic control of the air-conditioning system. On the basis of ensuring the reliability of the air-conditioning system and user comfort, the outdoor fan can be reduced. The operating noise further enhances the user experience.
[0061] The air-conditioning system 100 according to the embodiment of the present invention further includes a controller, which executes the control method of the air-conditioning system described in the foregoing embodiment.
[0062] According to the air-conditioning system 100 of the embodiment of the present invention, by adopting the above-mentioned control method for control, the air-conditioning system can control the windshield of the outdoor fan in real time according to the outdoor ambient temperature and the exhaust pressure of the outdoor unit, thus ensuring the reliability and user Based on the comfort of use, the operating noise of the outdoor fan is reduced, and the user experience is further improved.
[0063] Other configurations and operations of the air conditioning system 100 according to the embodiment of the present invention are known to those of ordinary skill in the art, and will not be described in detail here.
