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.
An air conditioner, a method of correcting the air conditioner, and a computer-readable storage medium according to embodiments of the present invention will be described with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method of an air conditioner capable of requiring correction according to an embodiment of the present invention.
In an embodiment of the present invention, as shown in figure 2,
as shown in fig. 1, the method for correcting the energy demand of the air conditioner comprises the following steps:
and S1, acquiring the operation mode and the target temperature of the air conditioner, and acquiring the outlet water temperature, the outdoor environment temperature and the coil temperature of the indoor heat exchanger of the indoor unit in the current operation mode in real time.
Specifically, the operation mode of the air conditioner includes a heating mode and a cooling mode, and the target temperature may be a target temperature Ts of the operation of the air conditioner set by a user through a control device (e.g., an air conditioner remote controller, an intelligent terminal, etc.).
In an embodiment of the present invention, as shown in fig. 2, an air conditioner includes an indoor unit and an outdoor unit, and the indoor unit includes an indoor heat exchanger. The outdoor unit is connected with the indoor heat exchanger through a refrigerant pipe (comprising a refrigerant inlet pipe a1 and a refrigerant outlet pipe a2), the indoor unit is connected with an external building through a water pipe (comprising a water inlet pipe b1 and a water outlet pipe b2) to realize water inlet and outward drainage, and the control device can send a target temperature Ts to the indoor unit through communication connection of infrared signals, Bluetooth and the like so as to control the air conditioner.
Specifically, temperature sensors c1, c2 and c3 can be respectively installed at the water outlet pipe b2 of the indoor unit, the refrigerant inlet pipe a1 and the outdoor unit shell so as to correspondingly detect the outlet water temperature T1 of the indoor unit, the coil temperature T2 of the indoor heat exchanger and the outdoor environment temperature T3.
S2, acquiring a first energy requirement correction value according to a temperature interval to which the difference between the outlet water temperature of the current indoor unit and the target temperature belongs, and performing addition and subtraction correction on the current energy requirement to be corrected of the air conditioner according to the first energy requirement correction value to obtain a first energy requirement.
Specifically, when the step S2 is executed for the first time, the current energy to be corrected needs to be the initial energy, which needs to be equal to the preset coefficient, for example, when the preset coefficient is 1 and the air conditioner number is 4, the initial energy needs to be equal to 1 × 4 or 4. When the step S2 is executed the Nth time, the current energy to be corrected is the first energy required by the Nth-1 th time, wherein N is not less than 2 and is an integer.
The corresponding relation between the temperature interval to which the difference (which can be the absolute value of the difference) between the outlet water temperature of the indoor unit and the target temperature belongs and the first correction value can be established in advance through tests and stored. Specifically, the temperature interval is at least two.
In one example, the first energy-demand correction value is a constant value in each temperature interval, and the larger the temperature value of the temperature interval is, the larger the first energy-demand correction value is, for example, the first energy-demand correction value corresponding to the interval [2,4) is larger than the first energy-demand correction value corresponding to the interval [0, 2).
For example, the first correction value may be set to-4 to 4, the current energy to be corrected needs to be 4, when the air conditioner operates in the heating mode, and the interval to which the difference between the outlet water temperature (e.g., 5 ℃) and the target temperature (e.g., 22 ℃) is 17 ℃ is [16, + ∞ ], the first energy to be corrected needs to be the maximum value of 4, and at this time, the current energy to be corrected needs to be corrected, that is, the first energy needs to be 4+4 to 8, so that the air conditioner operates at a higher frequency to improve the heating effect; when the air conditioner operates in a heating mode, and the interval of the difference value 3 ℃ between the outlet water temperature (such as 19 ℃) and the target temperature (such as 22 ℃) of the current indoor unit is [2,4 ], a first energy required correction value can be obtained to be-3, and at the moment, the current energy to be corrected can be required to be corrected and corrected, namely the first energy required value is 4-3 to 1, so that the frequency of the air conditioner is reduced, and the energy consumption is reduced; when the air conditioner operates in a refrigeration mode, and the interval to which the difference value 11 ℃ between the outlet water temperature (such as 33 ℃) and the target temperature (such as 22 ℃) of the current indoor unit belongs is [10, 12 ], a first energy requirement correction value can be obtained to be 1, and at the moment, the current energy to be corrected can be corrected in a sum mode, namely the first energy requirement is 4+1 or 5, so that the air conditioner operates at a high frequency to improve the refrigeration effect; when the air conditioner operates in a refrigeration mode, and the difference value between the outlet water temperature (such as 31 ℃) and the target temperature (such as 22 ℃) of the current indoor unit is 9 ℃ belonging to the interval [8, 10 ], the first energy requirement correction value can be obtained to be 0, and at the moment, the current energy requirement to be corrected is maintained.
In another example, the first energy demand correction value has a positive correlation curve with the difference value in at least one temperature interval, and the first energy demand correction value has a constant value in other temperature intervals. For example, at a certain point a (i.e. the temperature difference) in the interval [0,16) and the first energy requirement correction value d1, there may be a relation d1 ═ k × a, where k > 0 and is constant, i.e. when the difference is in the interval [0,16), the difference is in direct proportion to the first energy requirement correction value d 1; interval [16, + ∞), the first correction value that can be required is the maximum value that is desirable, in which case d1 can be k 16.
It should be noted that, the value of the first energy-demand correction value may be positive or negative, for example, 4 to 4, and at this time, only the energy to be corrected may be summed, that is, when the energy demand needs to be increased, the first energy-demand correction value is positive and a positive value is added; when the energy requirement needs to be reduced, the first energy requirement correction value is negative, and a negative value is added. The value of the first energy-to-be-corrected value can also be positive, for example, 0-4, and at the moment, the energy to be corrected can be subjected to sum or difference processing according to the requirement, namely, when the energy requirement needs to be increased, a positive value is added; when the energy requirement needs to be reduced, reducing a positive value; the value of the first energy-to-be-corrected value can also be negative, for example, minus 4 to 0, and at the moment, the energy to be corrected can be subjected to subtraction or summation treatment according to needs, namely, when the energy needs to be increased, a negative value is reduced; when the energy requirement needs to be reduced, a negative value is added.
And S3, correcting the first energy requirement according to the first energy requirement and the current maximum energy requirement of the air conditioner.
The preset time can be calibrated according to needs, and optionally, the preset time is a value within 1-3 minutes, such as 2 minutes.
In one embodiment of the present invention, after the first energy requirement is corrected, the air conditioner is controlled to operate for the corrected first energy requirement for the preset time, and the process returns to the step S2.
Further, as shown in fig. 3, the step S3 may include the following steps:
and S31, calculating to obtain a second energy demand according to the first energy demand and the current maximum energy demand of the air conditioner.
Specifically, the second energy requirement is min (the first energy requirement, the current maximum energy requirement), that is, the second energy requirement takes the smaller value of the first energy requirement and the current maximum energy requirement.
The current maximum energy requirement can be determined according to the difference between the outlet water temperature of the current indoor unit and the current outdoor environment temperature, and the larger the difference between the outlet water temperature of the current indoor unit and the current outdoor environment temperature is, the larger the current maximum energy requirement is. For example, the difference between the current outlet water temperature of the indoor unit and the current outdoor environment temperature is 10 ℃, and the current maximum energy requirement can be 21; the difference between the current outlet water temperature of the indoor unit and the current outdoor environment temperature is 15 ℃, the current maximum energy requirement can be 25, and the like.
Optionally, a corresponding relationship between the current maximum energy requirement and the difference between the current outlet water temperature of the indoor unit and the current outdoor environment temperature may be established in advance through experiments, and the corresponding relationship is stored, so that the indoor unit can be directly searched and called when needed.
S32, whether the first energy demand is larger than or equal to the current maximum energy demand or not and whether the accumulated times of the first energy demand larger than or equal to the current maximum energy demand are smaller than the preset times or not are judged.
The preset times can be calibrated according to needs, and optionally, the preset times is 1-3 times, such as 2 times.
And S33, if the first energy demand is smaller than the current maximum energy demand, or the accumulated times are smaller than the preset times, acquiring a second energy demand correction value according to the outdoor environment temperature, and performing percentage correction on the second energy demand by using the second energy demand correction value to obtain a third energy demand.
Specifically, if the first energy requirement is smaller than the current maximum energy requirement, or the accumulated number of times is smaller than the preset number of times, it indicates that the addition, subtraction, and percentage correction can still meet the requirement of outlet water temperature adjustment, and at this time, correction can be performed by using a smaller second energy requirement correction value. It should be understood that the percentage correction to the second energy requirement results in a third energy requirement, i.e. the third energy requirement is the second energy requirement and the second energy requirement correction.
S34, if the first energy requirement is larger than or equal to the current maximum energy requirement and the accumulated times are larger than or equal to the preset times, percentage correction is carried out on the second energy requirement by a third energy requirement correction value to obtain a fourth energy requirement, wherein the third energy requirement correction value is larger than the second energy requirement correction value.
Specifically, if the first energy requirement is greater than or equal to the current maximum energy requirement, and the accumulated number of times is greater than or equal to the preset number of times, it is indicated that the existing water temperature regulation requirement cannot be met by performing addition and subtraction correction with the first energy requirement correction value, and performing percentage correction with the second energy requirement correction value, and at this time, the second energy requirement can be subjected to percentage correction with a third energy requirement correction value that is greater than the second energy requirement correction value. For example, the third performance modifier value is + 10% of the second performance modifier value.
In an embodiment of the present invention, if the first energy requirement is greater than or equal to the current maximum energy requirement, and the accumulated number of times is greater than or equal to the preset number of times, the accumulated number of times may be cleared.
And S35, acquiring a fourth energy requirement correction value according to the coil temperature of the indoor heat exchanger, and performing addition and subtraction correction on the third energy requirement or the fourth energy requirement according to the fourth energy requirement correction value to obtain a fifth energy requirement.
And further, controlling the air conditioner to operate for a fifth preset time required by the air conditioner, and comparing the current outlet water temperature of the indoor unit with the outlet water temperature of the indoor unit before the preset time.
In one example, in the current cycle, in step S2, performing a correction, if the operation mode is the heating mode and the current outlet water temperature of the indoor unit is lower than the outlet water temperature of the indoor unit before the preset time, or if the operation mode is the cooling mode and the current outlet water temperature of the indoor unit is higher than the outlet water temperature of the indoor unit obtained before the preset time, returning to step S2, and performing the correction on the current to-be-corrected energy of the air conditioner; if the operation mode is the heating mode and the current outlet water temperature of the indoor unit is greater than or equal to the outlet water temperature of the indoor unit acquired before the preset time, or the operation mode is the cooling mode and the current outlet water temperature of the indoor unit is less than or equal to the outlet water temperature of the indoor unit acquired before the preset time, after the step S2 is returned, difference correction needs to be performed on the current to-be-corrected energy of the air conditioner.
For example, the air conditioner operates in a heating mode, in the N-1 cycle, the first energy requirement is that the current energy to be corrected needs + the first energy requirement correction value, after the air conditioner operates for the fifth energy requirement preset time, if the outlet water temperature of the current indoor unit is less than the outlet water temperature of the indoor unit before 2 minutes, the step returns to the step S2, and in the N cycle, the correction formula is that the first energy requirement is that the current energy to be corrected needs + the first energy requirement correction value; if the outlet water temperature of the current indoor unit is greater than or equal to the outlet water temperature of the indoor unit before 2 minutes, the step S2 is returned, and in the nth cycle, the correction formula is changed as follows: the first energy requirement is the current energy requirement to be corrected — the first energy requirement is the correction value. It should be noted that the first energy-demand correction value in the nth cycle is not necessarily the same as the first energy-demand correction value in the N-1 st cycle, that is, the difference between the outlet water temperature of the indoor unit and the target temperature in the nth cycle and the N-1 st cycle or the temperature interval to which the difference belongs is not necessarily the same.
In an embodiment of the present invention, in order to facilitate the execution processing of the correction method corresponding to the program, if a calculated value of any one of the above-mentioned requirements (including the current requirement to be corrected, the first to fifth requirements) is a decimal, the rounding-up processing is performed on the decimal, for example, if the calculated value of the third requirement is 2.3, then 3 is taken as the second requirement.
For ease of understanding, a modification method of the air conditioner according to the embodiment of the present invention will be described below with reference to fig. 4. As shown in fig. 4, when the air conditioner is operated in the heating mode, the method for correcting the energy demand of the air conditioner includes the following steps:
s101, after the air conditioner is powered on, initially requiring A to be a preset coefficient;
s102, obtaining a first required correction value d1 according to an interval to which a difference value between T1 and Ts belongs, and performing summation correction on A to obtain B, wherein B is A + d 1;
s103, new energy requirement D ═ min (B, C), where C is the current maximum energy requirement, determined from T1 and T3;
s104, judging whether the accumulated frequency of B being more than or equal to C is 2 or not;
s105, when B is less than C or the accumulated times of B being more than or equal to C is less than 2, obtaining a second energy required correction value D2 according to T3, and performing percentage correction on D to obtain E, wherein E is D D2;
s106, acquiring a fourth correction value d4 according to T2, and performing addition and subtraction correction on E to obtain F, wherein F is E + d 4;
s107, after timing for 2 minutes, if the current T1 is larger than the T1 before 2 minutes, the water temperature can be kept to rise, and the next round of water temperature is not required to be heated so as to avoid energy consumption, and if the current T1 is not larger than the T1 before 2 minutes, the water temperature is kept to rise;
s108, when the cumulative number of times that B is more than or equal to C is 2, the existing addition, subtraction and percentage correction cannot meet the requirement of water temperature rising, at the moment, the cumulative number is cleared, a third correction value D3 is obtained on the basis of D2 by + 10%, D is corrected to obtain E ', E' ═ D2, and the step S106 is carried out, so that the water temperature which can be raised to meet the set requirement is increased.
It should be noted that, after the air conditioner is powered on again, the initial energy requirement needs to be calculated again, and the percentage in step S105 returns to the initial value; step S106 is corrected on the basis of step S105, step S105 is corrected on the basis of step S103, only when step S102 is executed for the first time, correction is carried out on the initial energy A, and then correction is carried out on the basis of the last time B each time; the way to calculate is round up, e.g. 2.3 to 3.
To better understand the calculation process of steps S101 to S108, the air conditioner 16kW is taken as an example for heating, and if the preset coefficient is 1 and the number of matches is 4, it is required that the initial energy a is equal to the preset coefficient 1, 4, or 4. When the temperature of T3 is 13 ℃, d 2-40% is taken for correction (the range is 30-120%), d 3-50%, T1 does not reach Ts, d 1-4 (the range is-4 to +4) is taken, the current maximum energy C is 21 (corresponding to the frequency of 92Hz) according to T1 and T3, T2 is 38 ℃, and d 4-3 (the range is-1 to + 3). The exemplary corrective action procedure is shown in table 1 below:
TABLE 1
| Number of cycles | T1&Ts | T3 | T2 |
| 1 | 4+4＝8＜21 | 8*40％＝4 | 4+3＝7 |
| 2 | 8+4＝12＜21 | 12*40％＝5 | 5+3＝8 |
| 3 | 12+4＝16＜21 | 16*40％＝7 | 7+3＝10 |
| 4 | 16+4＝20＜21 | 20*40％＝8 | 8+3＝11 |
| 5 | 20+4＝24≥21＝21 | 21*40％＝9 | 9+3＝12 |
| 6 | 21+4＝25≥21＝21 | 21*50％＝11 | 11+3＝14 |
As can be seen from table 1, with the percentage correction of the related art, it is only necessary to fix the energy at 12, and if the temperature of T1 is still less than Ts at this time, the frequency cannot be adjusted up by 12, so that T1 cannot reach Ts. By adopting the correction method of the invention, the energy requirement can be increased to 14, so that the invention can better meet the requirement of users compared with the related art.
It should be understood that when modifications are required, the cooling mode and the heating mode are the same, and will not be described herein.
In conclusion, according to the method for correcting the energy requirement of the air conditioner, the problems that the air conditioner cannot increase the frequency and cannot reach the target temperature can be solved, the temperature regulation requirement of a user on the air conditioner is better met, and therefore the user experience is improved.
Further, the present invention proposes a computer-readable storage medium having stored thereon a computer program which is executed by a processor to implement the correction-capable method of an air conditioner described above.
