Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
According to the air conditioner control method, the interior of a machine room, a cabinet or other equipment needing temperature control is divided according to the positions of hot points, each hot point corresponds to a corresponding cooling requirement, each hot point is divided into a temperature control area, or the adjacent hot points with the same cooling requirement are divided into areas, and each temperature control area is provided with a temperature detection device so as to obtain the current temperature in the temperature control area.
In the embodiment of the present invention, taking dividing n temperature control areas as an example, as shown in fig. 1, the air conditioner control method includes the following steps:
step S11, first stage: starting the compressor at an initial frequency, and controlling the full-angle swing of the air guide sheet; and respectively detecting the current temperatures of the n temperature control areas, and increasing the running frequency of the compressor when the current temperatures are higher than the area set temperature of the corresponding temperature control areas until the current temperatures of the n temperature control areas are lower than the area set temperature of the corresponding temperature control areas.
Specifically, as shown in fig. 2, the first stage includes the following steps:
step S21: after the air conditioner is started at the initial frequency f0, the air guide plates are controlled to swing in a full angle.
The full angle needs to ensure that the air conditioner outlet air can be blown into all divided temperature control areas.
In some embodiments of the present invention, the operation of the air guiding plate in the full-angle swing mode from the temperature control area 1 to the temperature control area n, and then the operation of the air guiding plate in the temperature control area n to the temperature control area 1 is an operation period, and after the air conditioner is started at the initial frequency f0, the air guiding plate is controlled to swing in the full-angle swing mode for a set period, and the process proceeds to step S22.
Step S22: the current temperatures t1, t2, … …, tn of the n temperature-controlled regions are detected, respectively.
The temperature detection device of each temperature control area receives the current temperature in the temperature control area detected by the other temperature control areas.
Step S23: and judging the size relation between the current temperature and the area set temperature of the corresponding temperature control area aiming at each temperature control area.
In some embodiments of the present invention, a user may perform division of temperature control areas and set an area setting temperature Ti for each temperature control area in a target area, such as a machine room, a cabinet, or other equipment requiring temperature control, through an input device, such as an air conditioner control panel, a remote controller, an intelligent control terminal, or the like.
Specifically, within the full-angle range of the air guide sheet, the air guide position of the air guide sheet can be allocated for each temperature control area, and the air guide position comprises an air guide angle and an angle range; further, for each temperature control area, the area setting temperature is set according to the type of the hot spot in the temperature control area, for example, if a battery is disposed in the temperature control area 1, the area setting temperature for the temperature control area 1 is set to 30 °, if a server is disposed in the temperature control area 2, the area setting temperature for the temperature control area 2 is set to 45 °, and the like.
Step S24: and when the current temperature is higher than the zone set temperature of the corresponding temperature control zone, increasing the running frequency of the compressor until the current temperatures of the n temperature control zones are lower than the zone set temperature of the corresponding temperature control zone.
And for all the temperature control areas, as long as the current temperature is higher than the area set temperature corresponding to the temperature control area, the running frequency of the compressor is increased according to the set rule.
In some embodiments of the present invention, the air conditioner detects the relationship between the current temperature and the zone set temperature corresponding to the temperature controlled zone one by one starting from the temperature controlled zone 1 to the temperature controlled zone n, when the first current temperature is higher than the set temperature of the other corresponding temperature control areas, the running frequency of the compressor is increased by 2HZ, the detection of the subsequent temperature control areas is stopped, after the set time, the relation between the current temperature in each temperature control area and the area set temperature of the corresponding temperature control area is detected one by one from the temperature control area 1 again, when the first current temperature is higher than the set temperature of the other corresponding temperature control areas, the running frequency of the compressor is increased by 2HZ again, and the detection of the subsequent temperature control areas is stopped, and after the set time, the detection process is started again until the current temperature of all the temperature control areas is lower than the area set temperature of the corresponding temperature control area.
Step S12, second stage: judging the zone temperature difference of each temperature control zone, comparing the difference values of the zone temperature differences, entering a third stage when the difference values are smaller than a set difference value, or increasing the stay time of the air guide sheet in the temperature control zone with the minimum zone temperature difference until the difference values of the zone temperature differences are smaller than the set difference value; the area temperature difference is the difference between the current temperature and the area set temperature corresponding to the temperature control area.
Specifically, as shown in fig. 3, the second stage includes the following steps:
step S31: and judging the zone temperature difference of each temperature control zone.
The zone temperature difference is a difference Δ Ti between the current temperature Ti and a zone set temperature Ti corresponding to the temperature controlled zone.
Step S32: and comparing whether the difference value of the temperature difference of each area is smaller than a set difference value.
For all temperature controlled zones, two-by-two comparisons, i.e., Δ ti compared to Δ tj, i, j ∈ (1, 2, … …, n) and i ≠ j, determine the difference in temperature difference for each zone Δ tij = Δ ti- Δ tj.
When the difference values are all smaller than the set difference value, entering the third stage control; if the difference is greater than the set difference, step S33: and the stay time of the air guide sheet in the temperature control area with the minimum area temperature difference is prolonged.
Taking 3 temperature control areas as an example, the area temperature difference 1, the area temperature difference 2 and the area temperature difference 3 are respectively 5, 4 and 3, if the difference is set to be 1, and the difference of the area temperature differences is larger than the set difference 1, the residence time of the air guide sheet in the temperature control area 3 is increased for the temperature control area 3 with the minimum area temperature difference.
And repeating the steps S31 to S33 until the difference value of the temperature difference of each area is smaller than the set difference value.
And circulating until the difference value of the temperature difference of each area is smaller than the set difference value 1, and realizing the balanced distribution of the cold quantity of each temperature control area under the current compressor operation frequency by adjusting the air guiding duration of each temperature control area.
Step S13, third stage: and reducing the frequency of the compressor from the temperature control area with the minimum area temperature difference until the current temperature of each temperature control area is equal to the area set temperature of the corresponding temperature control area.
Specifically, as shown in fig. 4, the third stage includes the following steps:
step S41: and judging the zone temperature difference of each temperature control zone.
And determining the current temperature of each temperature control area at the moment, and comparing the current temperature with the area set temperature of the corresponding temperature control area to obtain the area temperature difference.
Step S42: and judging whether a temperature control area with the area temperature difference larger than the set temperature difference exists.
And if the temperature control area with the area temperature difference larger than the set temperature difference does not exist, the compressor operates according to the current frequency.
And step S43, when a temperature control area with the area temperature difference larger than the set temperature difference exists, reducing the frequency of the compressor.
The set temperature difference is a tolerance temperature control range which ensures the temperature reduction requirement of each temperature control area, for example, 1 ℃.
In some embodiments of the present invention, the compressor down-converts the frequency according to a set step length, for example, each time the frequency is reduced by 0.5HZ, the frequency is reduced according to 0.5HZ once when it is determined that there is a temperature control region where the temperature difference between the regions is greater than the set temperature difference, it is determined again after a set time length whether there is a temperature control region where the temperature difference between the regions is greater than the set temperature difference, the frequency is reduced again according to 0.5HZ when there is a temperature control region, it is determined again after the set time length, and the above steps are repeated until the temperature differences between.
At the moment, the compressor operates at the lowest frequency capable of guaranteeing the cooling requirements of all temperature control areas, is in the most power-saving state, and solves the technical problem of energy consumption in the conventional mode of reducing the overall temperature.
