Alternative embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Example one
Fig. 2 is a flowchart of a method for automatically adjusting static pressure of a fan according to an embodiment of the present invention, where the method is applied to an air conditioning system capable of implementing multi-zone temperature adjustment control, and as shown in fig. 2, the method includes the following steps:
s201, calculating the target operation time of each temperature-to-be-regulated area.
And S202, judging whether the static pressure of the fan meets the temperature regulation requirement or not according to the target operation time.
And S203, if the static pressure of the fan is not met, adjusting the static pressure of the fan.
The temperature-to-be-regulated area is a plurality of small areas divided into target areas, for example, a set of rooms are divided, and the temperature-to-be-regulated area is a bedroom, a living room, a kitchen and the like. The target operation time means a time required for the temperature change of the set temperature in the area to be tempered, for example, 10min is required for lowering the bedroom by 1 ℃. The temperature control requirement is also understood to be the static pressure requirement of the respective temperature control zone.
According to the air conditioner temperature regulating system, whether the static pressure of the air outlet machine meets the temperature regulating requirement or not can be judged through the target operation time of each temperature regulating area, so that the static pressure of the air outlet machine can be automatically regulated, the temperature of each area can meet the requirement, the refrigerating or heating effect is guaranteed, and the hardware cost is not increased.
In an optional embodiment, the step S201 of calculating the target operation time of each temperature-to-be-regulated area may include: acquiring the area of each region to be temperature-regulated; and calculating the time required by the temperature change set temperature of each region to be temperature-regulated according to the unit capacity information and the region area of each region to be temperature-regulated, and taking the time as the target running time.
The area of each temperature-regulating area can be input by a debugging person in the debugging stage. The unit capacity information includes: the rated power of the unit, and the preset temperature for each preset time for the indoor area of the preset area to fall or rise. It should be noted that the target operation time may be calculated for each temperature-controlled area individually, or all the temperature-controlled areas may share one target operation time. The set temperatures of the different zones may be the same or different. The set temperature related to the target running time and the preset temperature of the unit capacity information can be the same or different.
In the optional embodiment, the target operation time is obtained according to the unit capacity information and the area, the calculation method is simple, and a basis is provided for subsequently judging whether the static pressure of the fan meets the temperature regulation requirement.
S202 may be implemented in the following manner: acquiring actual operation data of each area to be temperature-regulated, wherein the actual operation data comprises: the actual operation time corresponding to the set temperature is changed in each area to be temperature-regulated, or the actual temperature change parameters of each area to be temperature-regulated are obtained after the unit operates the target operation time; and judging based on the actual operation data and the target operation data (including the target operation time and the set temperature) to determine whether the static pressure of the fan meets the temperature regulation requirement.
In an optional embodiment, the step S202 of determining whether the static pressure of the fan meets the temperature regulation requirement according to the target operation time includes: acquiring actual operation data of each area to be subjected to temperature regulation, wherein the actual operation data is actual operation time corresponding to the change set temperature of each area to be subjected to temperature regulation; judging whether the relation between the actual running time and the target running time meets a preset requirement or not; and if the judgment result of any area to be subjected to temperature regulation is negative, determining that the static pressure of the fan does not meet the temperature regulation requirement.
Correspondingly, the step S203 of adjusting the static pressure of the fan may include: and adjusting the static pressure of the fan according to a preset rule until the relation between the actual operation time and the target operation time of all the areas to be subjected to temperature regulation meets a preset requirement, namely the relation between the actual operation time and the target operation time of each area to be subjected to temperature regulation meets the preset requirement. Therefore, the static pressure of the fan can be adjusted to meet the temperature regulation requirement.
In an optional embodiment, the step S202 of determining whether the static pressure of the fan meets the temperature regulation requirement according to the target operation time includes: acquiring actual operation data of each area to be temperature regulated, wherein the actual operation data is an actual temperature change parameter of each area to be temperature regulated after the unit operates the target operation time; comparing the actual temperature change parameter with the set temperature; and if the comparison result of any region to be subjected to temperature regulation is inconsistent, determining that the static pressure of the fan does not meet the temperature regulation requirement.
Correspondingly, the step S203 of adjusting the static pressure of the fan may include: and adjusting the static pressure of the fan according to a preset rule until the actual temperature change parameters of all the areas to be temperature-adjusted are consistent with the set temperature, namely the actual temperature change parameters of each area to be temperature-adjusted are consistent with the set temperature. Therefore, the static pressure of the fan can be adjusted to meet the temperature regulation requirement.
When actual operation data are acquired, the air conditioner can be started to operate according to a preset static pressure value, the opening degree of an air valve of a corresponding area is adjusted according to the area of each area to be temperature-adjusted, and corresponding cooling capacity or heating capacity is distributed. The total capacity of the unit is fixed, the total area of a room is fixed, and the corresponding opening degree of the air valve can be adjusted according to the size of the total area occupied by the area, for example, the area of 10 square meters is opened for 10s in 60s, and the air valve is closed for 50 s; in the area of 30 square meters, the air valve is opened for 30s and closed for 30s in 60 s.
According to the embodiment, whether the static pressure of the fan meets the temperature regulation requirement or not is judged based on the comparison between the actual operation data and the target operation data, and the judgment mode is simple and reliable. And in all the areas to be regulated, if the actual operation data of any area does not accord with the target operation data, the static pressure of the fan is considered not to meet the temperature regulation requirement.
Further, determining whether the relationship between the actual running time and the target running time meets a preset requirement includes: judging whether the actual running time is consistent with the target running time; or determining a reference time range according to the target running time, and judging whether the actual running time is in the reference time range.
Wherein the reference time range may be determined according to the following rules: and calculating the maximum value and the minimum value corresponding to the target running time according to the preset deviation, and forming the reference time range by the maximum value and the minimum value. For example, if the preset deviation is 3min, the calculated target operation time is 20min, and the reference time is 17min to 23 min.
The embodiment determines according to the reference time range, and can avoid errors caused by other unexpected conditions, for example, a heat source in a room can cause slow temperature reduction.
The preset rule is that when the static pressure of the fan is insufficient or too high, the static pressure of the fan is increased or reduced according to a preset amplitude. Specifically, if the actual operation time is higher than the target operation time or the reference time range, or the actual temperature change parameter is lower than the set temperature, it indicates that the static pressure of the fan is insufficient, and the static pressure of the fan needs to be increased; if the actual operation time is lower than the target operation time or the reference time range, or the actual temperature change parameter is higher than the set temperature, the static pressure of the fan is indicated to be too large, and the static pressure of the fan needs to be reduced. The static pressure may specifically be adjusted according to a preset amplitude. Illustratively, the target is quickly approached by using a dichotomy, and each time the adjustment range is 50% of the last change, for example, if 50% of the maximum static pressure is smaller, the adjustment range is 75% of the maximum static pressure, and if the value is larger, the adjustment range is 62.5% of the maximum static pressure, and so on until the requirement is met. It is also possible to adjust a fixed amplitude, for example 10%, each time.
Preferably, after the static pressure of the fan is adjusted, the method may further include: and if the static pressure of the fan is adjusted to the maximum value or the minimum value, the actual running time and the target running time do not accord with the preset requirement or the actual temperature change parameter and the set temperature do not accord with each other, outputting abnormal prompt information.
In the preferred embodiment, when the static pressure of the fan is adjusted to the maximum value or the minimum value, abnormal prompt information is output to remind debugging personnel of overhauling and/or reminding users of paying attention, and machine set faults are found in time for maintenance.
For example, assuming a unit capacity of 36kW, a room with a square meter of 160 square meters can be driven to reduce by 1 ℃ every 10 min. After the 36kW unit is installed, the areas of an input area 1 and an input area 4 are respectively 20 square meters, the areas of an area 2, an area 3, an area 5 and an area 6 are respectively 10 square meters, and the area of an area 7 is 80 square meters, then the area is calculated, 2 ℃ reduction for all rooms is about 20min, corresponding air valve opening is adjusted according to the area of each area, corresponding cold energy is distributed, if the static pressure is normal, the time for reducing 2 ℃ in each area is basically achieved at the same time, and the time is about 20 min. Starting the air conditioner with 50% of maximum static pressure, if the time required for reducing the temperature of each area by 2 ℃ is about 15-25 min, the static pressure is proper, if 30min passes, if the temperature of the area which is far away from an internal machine is not reduced, such as the temperature of the area 3 or the area 6, the static pressure of the fan is too small, the area 3 or the area 6 is not blown out by cold air, the static pressure of the fan needs to be increased, the rotating speed of the fan is increased, the judgment is repeated, and the static pressure is increased until the time or temperature change requirement is met. And if the static pressure of the fan is increased to 100% or reduced to the minimum value, or the requirement of time or temperature change cannot be met, reporting an exception, and reminding debugging personnel to overhaul.
