Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
At present, a plurality of direct-current variable-frequency air conditioners can realize variable output operation, and according to statistics, the current air conditioner still generally has the phenomenon of frequent start and stop (the occupation ratio of more than once stop per hour reaches more than half) due to mismatching of the output of a multi-split air conditioner system and building load. And the frequent start and stop of the air conditioner is similar to the frequent start and stop of the vehicle, which can cause higher equipment energy consumption. In addition, the over-output of the air conditioner is caused by the overhigh condensation temperature (heating working condition) or the overlow evaporation temperature (cooling working condition), and at the moment, the multi-split air conditioning system is not operated at the optimal energy efficiency point under the condition of meeting the load. Therefore, the current air conditioner still does not fully utilize the capacity of the frequency conversion equipment to realize more efficient operation.
Generally, when an outdoor unit of a multi-split air conditioning system is in a stable operation stage and an indoor unit is in a start-up stage, in order to meet the requirement of the set temperature of the indoor unit, the multi-split air conditioning system is prone to over-response when the temperature of sucked air is adjusted, and particularly, when the indoor building load is small, the indoor unit is prone to entering a state of frequent warm-up shutdown. On one hand, the reason is that the indoor unit does not identify the indoor building load in place, so that the air output by the indoor unit is too large, the temperature rise/temperature drop rate of the indoor unit is large, and the indoor unit is stopped when reaching the temperature; on the other hand, under the building load, in each starting stage of the indoor unit, the set temperature return difference value corresponding to the multi-split air conditioning system cannot be adjusted in a self-adaptive manner according to the real-time running state, and still keeps consistent regular change, and particularly, the set temperature return difference value cannot be adjusted in a differentiated manner according to the installation environment or the set requirement of the indoor unit. That is, in the prior art, the set temperature return difference value and the air supply volume cannot be adaptively adjusted along with the current building requirements, so that the indoor unit easily enters the regular frequent warm-up shutdown phenomenon under the condition of coping with small loads, and the frequent warm-up shutdown causes higher equipment energy consumption.
In summary, when the outdoor unit of the multi-split air-conditioning system is kept in an operating state, the indoor unit is in a starting stage under the influence of the installation environment of the indoor unit and the actual building load demand, and the indoor unit is relatively easy to over-respond and enter a state of reaching a warm shutdown because the indoor building load is relatively small. As an example, referring to fig. 1, fig. 1 is a schematic diagram illustrating an indoor unit frequently entering a warm-up shutdown state. As can be seen from fig. 1, since the building load is too small, in the starting stage of the indoor unit, the air output by the indoor unit is too large, so that the condition that the indoor unit is shut down when the indoor unit reaches the temperature is quickly satisfied, and meanwhile, the set temperature return difference value is generally relatively fixed, and cannot be effectively adjusted according to the real-time state.
Therefore, the invention provides a self-adaptive adjustment method of a multi-split air conditioning system, which mainly aims at the technical problem that in the prior art, the multi-split air conditioning system cannot self-adaptively adjust the air supply quantity and the set temperature return difference value of an indoor unit, so that the indoor unit frequently reaches the temperature and stops working, and the equipment energy consumption is high. The self-adaptive adjusting method of the multi-split air-conditioning system can realize self-adaptive adjustment or correction of the air supply quantity and/or the set temperature return difference value of the indoor unit when the indoor unit is in the starting stage, thereby avoiding the phenomenon that the indoor unit is frequently stopped due to excessive response of the output of the multi-split air-conditioning system and reducing the energy consumption of the multi-split air-conditioning system.
An adaptive adjustment method, apparatus, system, and medium of a multi-split air conditioning system according to an embodiment of the present invention are described below with reference to the accompanying drawings.
Fig. 2 is a schematic flowchart of a method for adaptive adjustment of a multi-split air conditioning system according to an embodiment of the present invention.
The self-adaptive adjusting method of the multi-split air conditioning system provided by the embodiment of the invention can be applied to the multi-split air conditioning system. The multi-split air conditioning system may include at least one outdoor unit and a plurality of indoor units.
As shown in fig. 2, the adaptive adjustment method of the multi-split air conditioning system includes the steps of:
and step 101, receiving a starting instruction, and controlling the multi-split air conditioning system to start according to the starting instruction.
In the embodiment of the present invention, the start instruction may be triggered by a user, for example, the user may trigger the start instruction through a control panel of the multi-split air conditioning system, a remote controller, and an Application (APP for short) installed in the mobile terminal and configured to control the multi-split air conditioning system.
In the embodiment of the invention, after the multi-split air conditioning system receives the starting instruction, the multi-split air conditioning system can be controlled to be started according to the starting instruction.
And 102, judging whether at least one indoor unit in the multi-split air-conditioning system is started for the first time.
In the embodiment of the invention, when the multi-split air-conditioning system is in a power-on state, whether an outdoor unit of the multi-split air-conditioning system is in an operation stage and whether an indoor unit corresponding to the outdoor unit is in a starting stage can be detected, and when the outdoor unit is in the operation stage and the indoor unit corresponding to the outdoor unit is in the operation stage, whether the indoor unit is started for the first time after being powered on can be judged.
And 103, when the indoor unit is not started for the first time, correcting the initial value of the air supply quantity and/or the set temperature return difference value in the starting stage of the indoor unit to generate a target value of the air supply quantity and/or the set temperature return difference value.
In the embodiment of the invention, the set temperature return difference value refers to the difference value of the set temperature and the set temperature + the set temperature return difference value when the indoor temperature is in the room]In between, the indoor unit does not operate. Wherein the set temperature is a temperature set by a user. For example, the flag sets the temperature to TsetThe value of the return difference of the set temperature of the mark is Ts。
In the embodiment of the present invention, the starting stage refers to a time period from the time when the indoor unit starts to start to the τ th minute, where τ is preset. For example, when the indoor unit is started for the second time, the starting stage of the second start is a time period from the time when the outdoor unit enters the second start to the τ th minute.
In the embodiment of the invention, when the indoor unit is firstly started after being powered on, because the intervals of the indoor unit for achieving the temperature shutdown are generally different for different building load rates, when the indoor unit is firstly started after being powered on, the air supply quantity and/or the set temperature return difference value of the indoor unit can be not adjusted in a self-adaptive manner, namely the initial value of the air supply quantity and/or the initial value of the set temperature return difference value can be used as the target value of the air supply quantity and/or the target value of the set temperature return difference value corresponding to the starting stage of the current starting, so as to control the multi-split air conditioning system according to the target value. Wherein the initial value is preset.
When the indoor unit is not started for the first time, the initial value of the air supply amount and/or the initial value of the set temperature return difference value may be corrected at the start stage of the indoor unit to generate the target value of the air supply amount and/or the target value of the set temperature return difference value.
In a possible implementation manner of the embodiment of the present invention, when the indoor unit is not started for the first time, the initial value of the air supply amount may be corrected to generate the target value of the air supply amount at the start stage of the indoor unit.
Specifically, the time when the indoor unit is started up for the first time and the indoor unit is shut down for the first time when the indoor unit is started up for the first time, which is an interval duration between the time when the indoor unit is started up for the first time and the time when the indoor unit is shut down for the first time, may be recorded, and for example, the interval duration is marked as t (1). And determining a corrected value delta Ga (1) corresponding to the second startup according to the recorded time when the indoor unit is in warm shutdown at the first startup, for example, the inverse relationship between t (1) and delta Ga (1) is formed, namely the longer t (1), the smaller delta Ga (1) is, the shorter t (1) is, and the larger delta Ga (1) is.
For example, a corresponding relationship between the time of each temperature-reaching shutdown and the correction value may be preset, for example, the time of the temperature-reaching shutdown and the correction value may have an inverse relationship, so in the embodiment of the present invention, the corresponding relationship may be queried according to the recorded time of the temperature-reaching shutdown of the indoor unit at the time of the first startup, and the correction value corresponding to the second startup may be determined.
Then, the target value of the air supply amount corresponding to the start stage of the second start may be determined based on the correction value corresponding to the second start and the initial value of the air supply amount. For example, if the initial value of the flag air-blowing amount is Ga (1), and the target value of the air-blowing amount corresponding to the start-up stage of the second start-up is Ga (2), Ga (2) is Ga (1) + Δ Ga (1).
Similarly, a time period when the indoor unit has a warm-up shutdown at the time of the second startup, for example, may be recorded as t (2), and the correction value Δ Ga (2) corresponding to the third startup may be determined based on the recorded time period when the indoor unit has a warm-up shutdown at the time of the second startup. After that, the target value of the air supply amount corresponding to the start stage of the second start may be updated based on the correction value corresponding to the third start, and the target value of the air supply amount corresponding to the start stage of the third start may be determined. For example, if the target value of the air blowing amount corresponding to the activation stage indicating the third activation is Ga (3), Ga (3) is Ga (2) + Δ Ga (2).
By analogy, a target value of the air-blowing amount corresponding to the start-up stage of each start-up can be obtained, and for example, when the target value of the air-blowing amount corresponding to the start-up stage of the k +1 th start-up is Ga (k +1), Ga (k +1) ═ Ga (k) + Δ Ga (k), the multi-split air-conditioning system can be controlled according to the target value of the air-blowing amount corresponding to the start-up stage of each start-up.
That is, the correction value corresponding to the current start may be determined according to the recorded use time of the indoor unit that has reached the warm stop at the last start, and the target value of the air supply amount corresponding to the start stage of the last start may be updated according to the correction value corresponding to the current start, so as to determine the target value of the air supply amount corresponding to the start stage of the current start. Therefore, when the indoor unit is started at the last time and stops working due to temperature rise, the air supply quantity of the indoor unit can be adjusted in a self-adaptive mode, the phenomenon that the indoor unit frequently stops working due to excessive response of output of the multi-split air-conditioning system is avoided, and energy consumption of the multi-split air-conditioning system is reduced.
As an example, fig. 3 is a schematic diagram illustrating a correspondence relationship between time t (i) for warm-up shutdown and a corrected value Δ ga (i) of the air supply amount in the embodiment of the present invention. For example, when the indoor unit is first started up and the time t (1) for the indoor unit to come to a warm stop is t1, Δ Ga (1) is E1, when the time t (2) for the indoor unit to come to a warm stop is t2, Δ Ga (2) is D1, and when the time t (3) for the indoor unit to come to a warm stop is t3, Δ Ga (3) is C1.
In another possible implementation manner of the embodiment of the present invention, when the indoor unit is not started for the first time, the initial value of the set temperature back difference value may be corrected in the starting stage of the indoor unit to generate the target value of the set temperature back difference value.
In the embodiment of the invention, the temperature change rate of the last starting stage can be determined, for example, when the multi-split air-conditioning system is in a refrigerating working condition, the temperature change rate can be a cooling rate, and when the multi-split air-conditioning system is in a heating working condition, the temperature change rate can be a heating rate. The temperature change rate can be obtained by calculating the change rate corresponding to the indoor temperature from the starting time to the set duration.
Then, a ratio of the temperature change rate to a target temperature change rate may be calculated, where the target temperature change rate is preset, the target temperature change rate is a tolerable temperature change rate corresponding to a user, the target temperature change rate may be a target cooling rate when the multi-split air-conditioning system is in a cooling condition, and the target temperature change rate may be a target heating rate when the multi-split air-conditioning system is in a heating condition. The target temperature decreasing rate and the target temperature increasing rate may be the same or different, which is not limited in the embodiments of the present invention, for example, the target temperature changing rate may be 2 ℃/10 minutes. And judging whether the ratio is greater than or equal to a preset threshold (for example, 1), and under the condition that the ratio is greater than or equal to the preset threshold, determining that the load of the indoor space where the indoor unit is located is small, and at the moment, not starting temperature adjustment, so that the set temperature return difference value can be restored to an initial value, that is, the initial value of the set temperature return difference value is used as a target value of the set temperature return difference value corresponding to the starting stage of the starting.
And under the condition that the ratio is smaller than the preset threshold, determining a correction value corresponding to the current starting according to the recorded use time of the indoor unit reaching the temperature shutdown when the indoor unit is started last time, updating the target value of the set temperature back difference value corresponding to the starting stage of the previous starting according to the correction value corresponding to the current starting, and determining the target value of the set temperature back difference value corresponding to the starting stage of the current starting.
For example, a time T (1) when the indoor unit has a warm-up shutdown at the first start-up may be recorded, and the correction value Δ T (1) corresponding to the second start-up may be determined according to the recorded time T (1) when the indoor unit has a warm-up shutdown at the first start-up, for example, the longer T (1), the smaller Δ T (1), and the shorter T (1), the larger Δ T (1) may be.
Then, the target value of the set temperature return difference value corresponding to the starting stage of the second start can be determined according to the correction value corresponding to the second start and the initial value of the set temperature return difference value. For example, if the initial value of the set temperature setback value is set to Ts (1), and the target value of the set temperature setback value corresponding to the start phase of the second start is set to Ts (2), Ts (2) is Ts (1) + Δ T (1).
Similarly, the time when the indoor unit has a warm-up shutdown at the time of the second startup may be recorded, for example, as T (2), and the correction value Δ T (2) corresponding to the third startup may be determined according to the recorded time when the indoor unit has a warm-up shutdown at the time of the second startup. Then, the target value of the set temperature back pressure value corresponding to the starting stage of the second start may be updated according to the correction value corresponding to the third start, and the target value of the set temperature back pressure value corresponding to the starting stage of the third start may be determined. For example, if the target value of the set temperature setback value corresponding to the start phase of the third start is Ts (3), Ts (3) is Ts (2) + Δ T (2).
By analogy, a target value of the set temperature backstepping value corresponding to the start stage of each start can be obtained, for example, if the target value of the set temperature backstepping value corresponding to the start stage of the k +1 th start is marked as Ts (k +1), Ts (k +1) ═ Ts (k) + Δ t (k).
Therefore, when the indoor unit is started at the last time and stops working due to temperature reaching, the set temperature return difference value of the indoor unit can be adjusted in a self-adaptive mode, the phenomenon that the indoor unit frequently stops working due to excessive response of the output of the multi-split air-conditioning system is avoided, and the energy consumption of the multi-split air-conditioning system is reduced.
As an example, fig. 4 is a schematic diagram illustrating a corresponding relationship between the time t (i) for achieving warm shutdown and the correction value Δ t (i) of the set temperature back difference value in the embodiment of the present invention. For example, when the indoor unit is first started up and the time T (1) for the indoor unit to come to a warm stop is T1 ', Δ T (1) is E2, when the time T (2) for the indoor unit to come to a warm stop is T2 ' at the second start, Δ T (2) is D2, and when the time T (3) for the indoor unit to come to a warm stop is T3 ' at the third start, Δ T (3) is C2.
In another possible implementation manner of the embodiment of the present invention, when the indoor unit is not started for the first time, the initial value of the air supply amount and the initial value of the set temperature back pressure value may be corrected at the start stage of the indoor unit to generate the target value of the air supply amount and the target value of the set temperature back pressure value.
In one example, in the start-up phase of the indoor unit, the initial value of the air supply amount may be corrected to generate a target value of the air supply amount, and the multi-split air conditioning system may be controlled according to the target value of the air supply amount, and then the initial value of the set temperature return difference value may be corrected to generate a target value of the set temperature return difference value, and the multi-split air conditioning system may be controlled according to the target value of the air supply amount. That is, in the embodiment of the present invention, the air supply amount of the indoor unit may be corrected according to the air supply amount correction logic, and then the set temperature return difference value of the multi-split air conditioning system may be corrected according to the set temperature return difference value correction logic. The logic of correcting the return difference between the air supply volume and the set temperature is the same as the above process, and is not described again here.
In another example, in the starting stage of the indoor unit, the initial value of the set temperature return difference value may be corrected to generate a target value of the set temperature return difference value, and the multi-split air conditioning system may be controlled according to the target value of the air supply amount, and then the initial value of the air supply amount may be corrected to generate a target value of the air supply amount, and the multi-split air conditioning system may be controlled according to the target value of the air supply amount. That is, in the embodiment of the present invention, the set temperature return difference value of the multi-split air conditioning system may be first corrected according to the correction logic of the set temperature return difference value, and then the air volume of the indoor unit may be corrected according to the correction logic of the air volume.
And 104, controlling the multi-split air conditioning system according to the target value.
In the embodiment of the invention, after the target value of the air supply volume and/or the target value of the set temperature return difference value corresponding to the starting stage of the starting process is determined, the multi-split air conditioning system can be controlled according to the target value of the air supply volume and/or the target value of the set temperature return difference value in the starting process. Therefore, the self-adaptive adjustment of the air supply quantity and/or the set temperature return difference value of the indoor unit can be realized, so that the phenomenon that the indoor unit is frequently stopped due to the fact that the output of the multi-split air-conditioning system excessively responds is avoided, and the energy consumption of the multi-split air-conditioning system is reduced.
According to the self-adaptive adjusting method of the multi-split air-conditioning system, whether at least one indoor unit in the multi-split air-conditioning system is started for the first time is judged by receiving the starting instruction and controlling the multi-split air-conditioning system to be started according to the starting instruction, and when the indoor unit is not started for the first time, the initial value of the air supply quantity and/or the set temperature return difference value is corrected in the starting stage of the indoor unit to generate the target value of the air supply quantity and/or the set temperature return difference value, so that the multi-split air-conditioning system is controlled according to the target value. Therefore, the self-adaptive adjustment of the air supply quantity and/or the set temperature return difference value of the indoor unit can be realized in the starting stage, so that the phenomenon that the indoor unit is frequently stopped due to excessive response of the output of the multi-split air-conditioning system is avoided, and the energy consumption of the multi-split air-conditioning system is reduced.
In a possible implementation manner of the embodiment of the present invention, in the starting stage of the ith start of the indoor unit, if the indoor unit of the multi-split air conditioning system does not enter into the warm shutdown any more, the target value corresponding to the starting stage of the ith start may be kept unchanged. Wherein i is a positive integer.
In a possible implementation manner of the embodiment of the present invention, when the target value of the air blowing amount is corrected, the target value is kept unchanged when the target value corresponding to the starting stage of the i-th start of the indoor unit reaches the set extreme value. That is, for each start of the indoor unit, if the target value of the multi-split air conditioning system is adjusted to the set extreme value, and the indoor unit still has a temperature stop phenomenon in the corresponding start stage, the target value may be kept unchanged, or the set extreme value may be output to control the multi-split air conditioning system according to the set extreme value.
In consideration of the situation that the temperature shutdown and the heating comfort or the cooling comfort conflict when the multi-split air conditioning system is adjusted, particularly under the condition of small load, the target value of the air supply quantity of the indoor unit needs to be limited, so that the set extreme value corresponding to the air supply quantity can be set to be Ga in combination with the actual demandminAnd GamaxIf the target value of the air supply quantity of the multi-split air conditioning system meets Ga for each start of the indoor unitminAnd GamaxE.g. Ga (i) less than or equal to GaminOr Ga (i) is greater than or equal to GamaxWhen the adjustment cannot be continued, Ga at that time can be retainedminOr GamaxAnd the control of the next starting stage is carried out unchanged, so that the requirements of energy conservation and comfort can be met.
It should be noted that, although the target value is corrected, the phenomenon that the indoor unit is frequently stopped due to excessive response of the output of the multi-split air conditioning system can be avoided, so as to reduce the energy consumption of the multi-split air conditioning system, the multi-split air conditioning system is controlled according to the corrected target value, and the actual experience effect of the user is not considered, that is, the comfort of the indoor environment cannot be ensured. Therefore, as a possible implementation manner of the embodiment of the present invention, after the indoor unit enters the stable stage, the difference between the actual indoor temperature of the indoor space where the indoor unit is located and the set temperature may be detected, so as to correct or adjust back the target value according to the difference.
The above process is described in detail with reference to example two.
Fig. 5 is a flowchart illustrating an adaptive adjustment method of a multi-split air conditioning system according to a second embodiment of the present invention.
As shown in fig. 5, based on the embodiment shown in fig. 2, the adaptive adjustment method of the multi-split air conditioning system may further include the following steps:
in step 201, after the indoor unit enters a stable stage, a difference between an actual indoor temperature and a set temperature is detected.
In this embodiment of the present invention, the time period after the start-up phase may be a stable phase, for example, the stable phase may refer to a time period after the τ th minute after the outdoor unit starts up. Wherein τ is greater than t (k).
In the embodiment of the invention, the set temperature is the temperature set by the user, and the set temperature of the room temperature can be determined directly according to the temperature set by the user. For example, the mark room temperature is set to Tset。
In the embodiment of the invention, the temperature of the indoor space where the indoor unit is located can be detected through the relevant temperature sensor after the indoor unit enters the stabilization stage, so that the data acquired by the relevant temperature sensor can be acquired to determine the actual indoor temperature. For example, the actual indoor temperature is marked as T1。
The related temperature sensors can be arranged on the indoor units, and when the related temperature sensors acquire the actual indoor temperature, the indoor units or the multi-split air-conditioning system can directly acquire the actual indoor temperature acquired by the related temperature sensors. Or, the relevant temperature sensor may be set independently of the indoor unit, and after the relevant temperature sensor acquires the actual indoor temperature, the acquired actual indoor temperature may be transmitted to the multi-split air conditioning system in a Wireless communication manner such as bluetooth or Wireless local area network (WiFi), and accordingly, the multi-split air conditioning system may acquire the actual indoor temperature.
In this embodiment of the present invention, the difference between the actual indoor temperature and the set temperature may be a relative difference or may also be an absolute difference, which is not limited in this respect. For example, the flag difference is Δ T1, and when the difference is an absolute difference, the difference between the actual indoor temperature and the set temperature is: Δ T1 ═ T1-TsetWhen the difference is a relative difference, the difference between the actual indoor temperature and the set temperature may be: Δ T1 ═ T1-TsetOr, Δ T1 ═ Tset-T1。
In step 202, in the case that the difference is smaller than or equal to the allowable difference, the target value of the start-up phase is kept unchanged.
In the embodiment of the invention, the allowable difference value is preset. The allowable difference is an allowable difference corresponding to a comfortable feeling experienced by the user, and may be, for example, 2 ℃. It should be understood that the allowable difference value corresponding to the relative difference value may be different from the allowable difference value corresponding to the absolute difference value. For example, the allowable difference value may be a negative number when the difference value is a relative difference value, and a positive number when the difference value is an absolute difference value. For example, an allowable difference Δ T1 may be labeledset。
In the embodiment of the invention, when the difference value between the actual indoor temperature and the set temperature is less than or equal to the allowable threshold value, the indoor environment temperature is more comfortable, and therefore, the target value in the starting stage can be kept unchanged.
And 203, determining a corresponding callback amount according to the difference value and correcting the target value according to the callback amount under the condition that the difference value is larger than the allowable difference value.
In the embodiment of the invention, when the difference between the actual indoor temperature and the set temperature is larger than the allowable difference, the comfort of the indoor environment temperature is poor, so that the target value can be corrected or adjusted back to reduce the phenomenon of larger indoor temperature fluctuation.
Specifically, the corresponding callback amount may be determined according to the difference, and the target value may be corrected according to the callback amount.
As an example, the corresponding relationship between the different difference values and the adjusted amount may be preset, so that in the embodiment of the present invention, when the difference value between the actual indoor temperature and the set temperature is greater than the allowable difference value, the corresponding relationship may be queried, the adjusted amount corresponding to the difference value may be determined, and the target value may be corrected according to the adjusted amount.
For example, for the ith start, the corresponding feedback amount Δ η (i) may be determined based on the difference Δ T1(i) between the actual indoor temperature and the set temperature, and the target value of the corrected air blowing amount may be ga (i) + Δ η (i), and/or the target value of the corrected set temperature feedback value may be ts (i) + Δ η (i).
As an example, referring to fig. 6, fig. 6 is a schematic diagram of a relationship between the difference Δ T1(i) and the return amount Δ η (i) of the air supply amount in the embodiment of the present invention. For example, when Δ T1(i) is a1, Δ η (i) ═ E3, and when Δ T1(i) is a3, Δ η (i) ═ C3.
As another example, referring to fig. 7, fig. 7 is a diagram illustrating a correspondence relationship between the difference value Δ T1(i) and the set temperature return difference value Δ η (i) in the embodiment of the present invention. For example, when Δ T1(i) is b1, Δ η (i) ═ E4, and when Δ T1(i) is b3, Δ η (i) ═ C4.
In a possible implementation manner of the embodiment of the present invention, when the difference between the actual indoor temperature and the set temperature is greater than the allowable difference, the comfort of the indoor environment temperature is poor, and therefore, the corresponding adjustment amount may be determined according to the target use, and the target value may be corrected according to the adjustment amount. The target time is the interval duration between the first moment when the indoor unit is started recently and the second moment when the actual indoor temperature reaches the preset tolerance temperature. For example, the longer the target time, the slower the temperature change rate, the larger the value of the callback amount, while the shorter the target time, the faster the temperature change rate, the smaller the value of the callback amount.
The preset tolerance temperature is preset, and for example, the preset tolerance temperature may be 24 ℃, 25 ℃, 26 ℃ or the like.
Further, for the (i +1) th start, calculation may be performed according to a corrected target value corresponding to the ith start, and such a cycle is performed until the jth start, and if the jth start meets that the difference between the actual indoor temperature and the set temperature is less than or equal to the allowable difference for the first time, and the start stage does not stop at a temperature, the target value of the start stage of the jth start is maintained unchanged.
Further, for the jth startup, if the warm-up shutdown phenomenon occurs again, at this time, even if the difference is greater than the allowable difference, the target value is not corrected any more, and the target value corresponding to the last startup is maintained, that is, the maximum correction frequency can be set.
As an example, the corrected parameter is taken as the air output, referring to fig. 8, fig. 8 is a schematic flowchart of an adaptive adjustment method of a multi-split air conditioning system according to a third embodiment of the present invention.
When the multi-split air conditioning system is powered on, detecting that an outdoor unit is in an operating state, and enabling an indoor unit corresponding to the outdoor unit to be in a starting state; judging whether the last start is the first start of the indoor unit, and giving an initial value Ga (1) of air supply quantity to the first started indoor unit under the condition of the first start; and if the indoor unit is not started for the first time, judging whether the indoor unit is stopped at a temperature at the last starting stage, if the indoor unit is stopped at the temperature at the last starting stage, adaptively reducing the target value of the air supply quantity, namely determining a correction value (which is a negative value) corresponding to the current starting according to the use time of the indoor unit at the last starting stage when the indoor unit is stopped at the temperature, and updating the target value of the air supply quantity corresponding to the last starting stage according to the correction value corresponding to the current starting. The longer the time spent for the indoor unit to stop at the temperature in the last starting stage is, the larger the absolute value of the correction value is.
And if the indoor unit does not stop at the temperature in the last starting stage, taking the target value of the air supply amount corresponding to the last starting stage as the target value of the air supply amount corresponding to the current starting stage.
And determine whether the heating (heating condition)/cooling (cooling condition) of the current start stage or the current start stage meets the comfort requirement corresponding to the user? If the target value of the air supply quantity is not met, the target value of the air supply quantity is adjusted back in a self-adaptive mode, and if the target value of the air supply quantity is met, the target value of the air supply quantity is output.
As an example, referring to fig. 9, fig. 9 is a schematic diagram of a result of adaptive adjustment of the air volume corresponding to the indoor unit in the embodiment of the present invention. As can be seen from fig. 9, after the adaptive adjustment control, the air output of the indoor unit is significantly improved, the start-up stage does not frequently enter the warm-up shutdown any more, and the start-up operation can be more stably performed to the stable stage, so that the energy consumption of the multi-split air conditioning system can be reduced, the phenomenon of large indoor temperature fluctuation is reduced, and finally, the energy saving performance and the comfort of the multi-split air conditioning system are effectively improved.
As another example, taking the corrected parameter as the set temperature back difference value for example, referring to fig. 10, fig. 10 is a schematic flowchart of an adaptive adjustment method of a multi-split air conditioning system according to a fourth embodiment of the present invention.
1. When the multi-split air conditioning system is powered on, the outdoor unit is detected to be in the running state, the indoor unit corresponding to the outdoor unit is in the starting state, and a target temperature change rate is given, for example, under a refrigeration working condition, a target temperature reduction rate is given, and under a heating working condition, a target temperature increase rate is given.
2. And determining the ratio of the heating rate/cooling rate of the last starting stage to the target temperature change rate according to the recorded temperature data.
3. And (3) judging whether the ratio is smaller than a preset threshold (for example, 1), if so, executing the step 4, and if not, executing the step 12.
4. And under the condition that the temperature is smaller than the preset threshold value, judging whether the temperature of the indoor unit is reached to stop when the indoor unit is started for the last time, if so, executing the step 5, and if not, executing the step 7.
5. And under the condition of shutdown when the temperature is reached, the set temperature return difference value is adaptively relaxed.
For example, when the indoor unit is stopped at a temperature in the last starting stage, the corresponding correction value of the current starting is determined, and the target value of the set temperature return difference value corresponding to the last starting stage is updated according to the corresponding correction value of the current starting.
6. And (5) judging whether the indoor unit enters a temperature-reaching shutdown state in the current starting stage or the current starting stage, if so, returning to execute the step 5, and if not, executing the step 7.
7. And detecting the difference value between the actual indoor temperature and the set temperature in the stable operation stage of the indoor unit under the condition of entering a temperature-reaching shutdown state.
The difference is used for representing the comfort of the user in actual use, and if the difference is too large, the user is easy to feel too cold (cooling working condition) or too hot (heating working condition).
8. And judging whether the difference is larger than the allowable difference, if so, executing the step 9, and if not, executing the step 11.
9. And under the condition that the difference is larger than the allowable difference, the set temperature return difference is adaptively adjusted back.
10. And (4) judging whether the indoor unit reaches the temperature shutdown in the current starting stage or the current starting stage, if so, executing the step 11, otherwise, returning to execute the step 7 until the temperature shutdown is reached.
11. The current set temperature return difference value is maintained.
When the temperature-reaching shutdown occurs, outputting the current set temperature return difference value, wherein the reason is that the temperature-reaching shutdown exceeds the temperature range acceptable by the user, and the user may be uncomfortable due to the fact that the set temperature return difference value is continuously adjusted, so that the adjustment is not performed any more, and the current state is allowed to enter the temperature-reaching shutdown.
12. And if the temperature is greater than or equal to the preset threshold value, the temperature returns to the initial value of the set temperature return difference value.
After the self-adaptive adjustment control, under the conditions that the outdoor unit is in a stable stage and the indoor unit is in an operation stage, the condition that the indoor unit is frequently stopped due to the fact that the air output by the indoor unit is large or the set temperature return difference value is set unreasonably can be avoided, the self-adaptive adjustment of the air output of the indoor unit and the self-adaptive adjustment of the set temperature return difference value are achieved, and therefore the energy consumption of the multi-split air conditioning system is reduced, the phenomenon that the indoor temperature fluctuation is large is reduced, and finally the energy saving performance and the comfort of the multi-split air conditioning system are effectively improved.
