Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

and (5) performing air conditioner refrigeration operation.
S102, obtaining the outdoor environment temperature, the indoor environment temperature and the refrigerating operation length.
And S104, performing temperature compensation on the indoor environment temperature according to the outdoor environment temperature, the indoor environment temperature and the refrigerating operation time to obtain the indoor environment compensation temperature.
The indoor environment temperature is the temperature at which the temperature sensor in the indoor unit detects the height of the indoor unit, the indoor environment temperature at which the user is located is defined as the actual inner ring temperature, the indoor environment temperature can represent the actual inner ring temperature to a certain degree, and accordingly the refrigeration load of the air conditioner and the effect of the air conditioner on the indoor environment temperature can also be represented. Specifically, when the difference between the indoor environment temperature and the indoor set temperature set by the user is large, the fact that the demand of the current indoor environment for the refrigerating capacity is large needs to improve the adjusting effect of the air conditioner on the indoor environment temperature is represented, the compensation on the indoor environment temperature can be reduced along with the rise of the indoor environment temperature, so that the air conditioner can obtain a high indoor environment compensation temperature, the air conditioner can operate at a high frequency correspondingly to quickly cool and adjust the indoor environment, and the indoor environment temperature can quickly reach a comfortable range; when the difference value between the indoor environment temperature and the indoor set temperature is small, the requirement of the current indoor environment on the refrigerating capacity is represented to be small, so that the adjusting effect of the air conditioner on the indoor environment temperature can be reduced, specifically, the compensation on the indoor environment temperature can be increased along with the reduction of the difference value between the indoor environment temperature and the indoor set temperature, so that the air conditioner obtains the indoor environment compensation temperature which is lower and is closer to the actual inner ring temperature, and on the basis of ensuring the comfort level of the indoor environment, the air conditioner gradually reduces the frequency to achieve the effect of energy conservation.
The outdoor environment temperature indirectly determines the refrigeration load of the air conditioner and the effect of the air conditioner on the regulation of the indoor environment temperature, and particularly, when the outdoor environment temperature is in a higher range, the air conditioner has a weaker effect on the regulation of the indoor environment temperature, and can reduce the compensation on the indoor environment temperature along with the rise of the outdoor environment temperature, so that the air conditioner can obtain higher indoor environment compensation temperature, and correspondingly, the air conditioner can rapidly cool and regulate the indoor environment at higher frequency to achieve a more comfortable temperature range; when the outdoor environment temperature is in a lower range, the refrigeration load of the air conditioner is smaller, the indoor environment temperature is reduced more quickly, and the compensation for the indoor environment temperature can be reduced along with the reduction of the outdoor environment temperature, so that the damage to the compressor caused by frequent shutdown of the air conditioner and the consumption of electric energy are reduced.
The refrigerating operation duration is the continuous refrigerating operation duration of the air conditioner from the start, under the normal condition, the indoor environment temperature and the actual indoor environment temperature can be gradually reduced along with the operation of the air conditioner and are close to the indoor set temperature, therefore, the compensation of the indoor environment temperature can be increased by increasing the refrigerating operation duration, the air conditioner obtains the lower indoor environment compensation temperature, on the basis of ensuring the indoor environment comfort level, the air conditioner is enabled to be gradually lowered in frequency, and the energy-saving effect is achieved.
The air conditioner refrigeration temperature compensation method comprehensively considers the influence of three associated factors of outdoor environment temperature, indoor environment temperature and refrigeration operation time length on the refrigerating capacity demand of indoor environment and the refrigeration load of the air conditioner, carries out compensation more flexibly on the indoor environment temperature and fits the actual use environment, so that the air conditioner can rapidly adjust the indoor environment temperature to a comfortable range close to indoor set temperature, and can obtain the indoor environment compensation temperature closer to the actual temperature of an inner ring after reaching the comfortable range, on the basis of ensuring the comfort of users, the operation frequency of the air conditioner is reduced, and the energy-saving effect is achieved.
Alternatively, S104: carry out temperature compensation to indoor ambient temperature according to outdoor ambient temperature, indoor ambient temperature and length when refrigerating the operation to obtain in the step of indoor ambient compensation temperature, include: the indoor environment compensation temperature is calculated according to the following formula:
T internal patch ＝T Inner ring -△T；
Wherein, T Internal patch Temperature, deg.C, is compensated for the indoor environment; t is Inner ring Indoor ambient temperature, deg.C; delta T is the compensation temperature, DEG C.
The compensation temperature is calculated according to the following formula:
△T＝△T0·K1·K2+K3；
wherein, the delta T0 is the initial compensation temperature set according to the type of the air conditioner and is in DEG C; k1 is an outer ring influence coefficient determined according to the outdoor environment temperature; k2 is an inner ring influence coefficient determined according to the indoor environment temperature; k3 is the operating duration influence value determined according to the refrigerating operating duration, DEG C.
Determining an outer ring influence coefficient according to the outdoor environment temperature, determining an inner ring influence coefficient according to the indoor environment temperature, then synthesizing the outer ring influence coefficient, the product of the inner ring influence coefficient and the initial compensation temperature to be used as a first part compensation value, determining an operation time length influence value according to the refrigerating operation time length to be used as a second part compensation value, and then taking the sum of the first part compensation value and the second part compensation value as the total compensation temperature, wherein the outer ring influence coefficient changes along with the change of the outdoor environment temperature, the inner ring influence coefficient changes along with the change of the indoor environment temperature, and the operation time length influence value changes along with the change of the refrigerating operation time length, so that the obtained compensation temperature can flexibly compensate the indoor environment temperature; the difference through indoor ambient temperature and compensation temperature calculates to obtain the higher indoor ambient compensation temperature of flexibility ratio, accuracy, and then make the air conditioner can adjust indoor ambient temperature to the comfortable scope that is close to indoor settlement temperature fast, and reach the comfortable scope after, on the basis of guaranteeing user's travelling comfort, reduce air conditioner operating frequency, reach energy-conserving effect.
Specifically, for the value of the outer loop influence coefficient, the method further includes: within a preset temperature range, the influence coefficient of the outer ring is increased firstly and then reduced along with the increase of the outdoor environment temperature. The preset temperature range comprises the temperature range of the outdoor environment when the air conditioner needs to run in a refrigerating mode under normal conditions, such as [16 ℃ and 48 ℃), when the outdoor environment temperature is close to the preset lower limit temperature of the preset temperature range, the outdoor environment temperature is represented to be in a non-high temperature state, the refrigerating load of the air conditioner is small, the cooling effect on the indoor environment is high, the air conditioner can quickly adjust the temperature of the indoor environment, the outer ring influence coefficient is reduced along with the reduction of the outdoor environment temperature, the compensation temperature is correspondingly reduced, the compensation on the indoor environment temperature is reduced, and therefore the relatively large compensation temperature for the indoor environment is obtained, and the damage to the compressor and the consumption of electric energy caused by frequent shutdown due to the high refrigerating effect of the air conditioner are reduced. When the outdoor environment temperature is close to the preset upper limit temperature of the preset temperature range, the representation outdoor environment temperature is in a high-temperature state, the refrigeration load of the air conditioner is large, the cooling effect on the indoor environment is poor, the outer ring influence coefficient is reduced along with the rise of the outdoor environment temperature, the compensation temperature is correspondingly reduced, the compensation on the indoor environment temperature is reduced, and therefore the relatively large indoor environment compensation temperature is obtained, the air conditioner can rapidly cool and adjust the indoor environment in a high-frequency operation mode, the indoor environment can rapidly reach the relatively comfortable temperature range, and the use comfort of users is improved.
Optionally, the method further comprises: if the outdoor environment temperature is greater than or equal to the preset upper limit temperature or less than or equal to the preset lower limit temperature, K1=0. The preset upper limit temperature is the upper limit value of the preset temperature range, the preset lower limit temperature is the lower limit value of the preset temperature range, when the outdoor environment temperature is more than or equal to the preset upper limit temperature, the representation outdoor environment is in a high-temperature severe environment, K1 is 0, so as to cancel the first part compensation value, correspondingly reduce the compensation temperature as much as possible, correspondingly reduce the compensation to the indoor environment temperature as much as possible, so as to obtain higher indoor environment compensation temperature, the air conditioner can operate at higher frequency according to the higher indoor environment compensation temperature, the indoor environment is efficiently and quickly cooled, so that the indoor environment can reach a comfortable temperature range as quickly as possible, and the use comfort of a user is improved. When the outdoor environment temperature is less than or equal to the preset lower limit temperature, the representation that the outdoor environment is in a more comfortable environment or even a lower temperature environment is carried out, 0 is taken through K1 to reduce the compensation of the indoor environment temperature as far as possible so as to obtain a relatively higher indoor environment compensation temperature, and therefore the damage to the compressor and the consumption of electric energy caused by frequent shutdown of the air conditioner due to the lower indoor environment compensation temperature are reduced.
Specifically, if the outdoor environment temperature is greater than the preset lower limit temperature and less than or equal to the preset temperature standard value, K1= (T) Outer ring -T min )2/(T Standard of merit -T min ) 2; wherein, T Outer ring Outdoor ambient temperature, deg.C; t is a unit of min A preset lower limit temperature, DEG C; t is Standard of merit Is a preset temperature standard value, DEG C, the preset temperature standard value is greater than a preset lower limit temperature and less than a preset upper limit temperature. The preset temperature standard value is in a preset temperature rangeThe standard demarcation point inside the enclosure and in the preset temperature range represents the standard temperature of the outdoor environment when the air conditioner operates, and when T is measured Outer ring At (T) min ，T Standard of merit ]When the temperature is in a non-high temperature state, the outdoor environment temperature is represented, and when T is Outer ring Near T min In time, the air conditioner has low refrigeration load and high refrigeration effect on the indoor environment, along with T Outer ring The refrigerating load of the air conditioner is increased along with the increase of the air conditioner to gradually approach the standard refrigerating load, and the cooling effect of the air conditioner on the indoor environment gradually approaches the standard level along with the decrease of the air conditioner. Taking K1, K1-T according to the formula Outer ring Is a downward concave parabola which has an upward trend, and the curvature of the parabola follows T Outer ring Increases with increasing K1 and increasing K1 with T Outer ring Is increased by an increase in; when T is Outer ring Near T min When the temperature of the air conditioner is higher than the set temperature, the compensation temperature is correspondingly reduced, and the compensation for the indoor environment temperature is reduced, so that the relatively higher indoor environment compensation temperature is obtained, and the damage to the compressor and the consumption of electric energy caused by frequent shutdown of the air conditioner due to higher refrigeration effect are reduced; when T is Outer ring Near T Standard of reference When the temperature of the indoor environment is lowered, the air conditioner can be cooled to the indoor environment within a comfortable range quickly.
Further, if the outdoor environment temperature is greater than the preset temperature standard value and less than or equal to the preset upper limit temperature, K1= (T) Outer ring -T max )2/(T Standard of merit -T max ) 2; wherein, T max Is a predetermined upper limit temperature in deg.C. When T is Outer ring At [ T ] Standard of merit ，T max ) When T is in high temperature state, the outdoor environment is represented Outer ring Near T Standard of merit When the temperature of the air conditioner is lower than the standard temperature, the refrigerating load of the air conditioner is close to the standard refrigerating load, and the cooling effect of the air conditioner on the indoor environment tends to the standard level along with T Outer ring Increase of the cooling load of the air conditioner and the indoor environmentThe cooling effect becomes poor. Taking K1, K1-T according to the formula Outer ring Is a downward-concave parabola, and the curvature of the parabola follows T Outer ring Decreases with increasing K1 and increasing K1 with T Outer ring Is increased and decreased; when T is Outer ring Near T max When the temperature of the indoor environment reaches a temperature range which is comfortable, the air conditioner can quickly cool the indoor environment at a high frequency, so that the use comfort of a user is improved; when T is Outer ring Near T Standard of merit When the temperature of the indoor environment is lowered, the air conditioner can be cooled to the indoor environment within a comfortable range quickly.
Optionally, for the value of the inner loop influence coefficient, the method further includes: when the indoor set temperature is lower than the indoor initial temperature, the inner ring influence coefficient is increased along with the reduction of the indoor environment temperature. Under a normal state, along with the refrigeration operation of the air conditioner, the indoor environment temperature can gradually fall and approach the indoor set temperature, so that when the difference value between the indoor environment temperature and the indoor set temperature is large, the representation of the indoor environment temperature is high, large refrigeration capacity is needed to quickly cool, a large inner loop influence coefficient is selected to improve the compensation temperature, and therefore the compensation on the indoor environment temperature is increased, so that the air conditioner can obtain high indoor environment compensation temperature, and correspondingly operates at high frequency to quickly cool the indoor environment temperature to a comfortable range; along with the reduction of the indoor environment temperature, the demand of the current indoor environment on the refrigerating capacity is gradually reduced, and a smaller inner ring influence coefficient is selected to reduce the compensation temperature, so that the compensation on the indoor environment temperature is reduced, the air conditioner obtains the indoor environment compensation temperature which is lower and is closer to the actual inner ring temperature, and on the basis of ensuring the comfort level of the indoor environment, the air conditioner gradually reduces the frequency to achieve the effect of energy conservation.
Specifically, the method may include: acquiring indoor set temperature; if the indoor set temperature is equal to or higher than the indoor ambient temperature, K2=0. Under the working condition, the refrigeration load of the air conditioner is small, 0 is taken out through K2 to reduce the compensation of the indoor environment temperature as far as possible, and the relatively high indoor environment compensation temperature is correspondingly obtained, so that the damage to the compressor and the consumption of electric energy caused by frequent shutdown of the air conditioner due to the fact that the indoor environment compensation temperature is low are reduced.
If the indoor set temperature is less than the indoor ambient temperature, K2= (T) Inner ring -T Inner primer )/(T Is provided with -T Inner primer ) (ii) a Wherein, T Inner primer The indoor initial temperature is the temperature of the air conditioner when the air conditioner is started for refrigeration; t is Is provided with Set the temperature in the room at DEG C. Along with the refrigerating operation of the air conditioner, the indoor environment temperature gradually decreases and approaches to the indoor set temperature, correspondingly, the refrigerating load of the air conditioner gradually decreases, the temperature adjusting effect on the indoor environment gradually increases, K2 is taken according to the formula, and along with T Inner ring When the indoor environment temperature is close to the indoor set temperature, the value of K2 is gradually increased to obtain a larger compensation temperature and correspondingly obtain a smaller indoor environment compensation temperature, so that the frequency of the air conditioner is gradually reduced, and the energy-saving effect is achieved; and when the indoor environment temperature is close to the indoor initial temperature, acquiring smaller compensation temperature, and correspondingly acquiring larger indoor environment compensation temperature, so that the air conditioner operates at higher frequency, and the indoor environment temperature is adjusted to a comfortable range quickly and efficiently.
Specifically, the indoor initial temperature is an indoor environment temperature when the air conditioner is started in a refrigerating mode, and specifically includes first-time refrigerating start, recovery of refrigerating operation after reaching a temperature and shutdown, mode conversion to a refrigerating mode, and the like, and the indoor initial temperature needs to be obtained again for calculating K2 every time the air conditioner is started in the refrigerating mode.
Optionally, for the selection of the operation duration influence value, the method includes: acquiring standard refrigerating time; and if the length of the refrigerating operation is less than the refrigerating standard time length, K3=0. If the length of the refrigerating operation is more than or equal to the refrigerating standard length of time and less than two times of the refrigerating standard length of time, K3= K; if the length of the refrigerating operation is more than or equal to two times of the refrigerating standard time and less than four times of the refrigerating standard time, K3=2K; if the length of the refrigerating operation is more than or equal to four times of the refrigerating standard length, K3=3K; wherein k is greater than 0. The length of the refrigeration standard is the length of the shortest time required for reducing the temperature to the specified temperature according to the standard room temperature before the air conditioner leaves the factory, the length of the refrigeration operation is compared with the length of the refrigeration standard, along with the increase of the length of the refrigeration operation, the indoor environment temperature is gradually reduced, the refrigerating capacity demand is reduced, the K3 step value is gradually increased, the compensation temperature is increased, the compensation for the indoor environment temperature is improved, the acquired indoor environment compensation temperature step is reduced, on the premise of ensuring the indoor comfort, the air conditioner reduces the operation frequency along with the step value, and the energy-saving effect is achieved. Specifically, K3 is more than or equal to-2; preferably, k =1.
Specifically, the refrigerating operation duration is a continuous operation duration after the air conditioner is started for refrigeration, and specifically may include first-time refrigeration starting, recovery of refrigeration operation after reaching a temperature and shutdown, mode conversion to a refrigeration mode, and the like, and each time the air conditioner is started for refrigeration, the refrigerating operation duration needs to be obtained again for calculation of K3.
Optionally, for the value of K3, the method further includes: every first preset time is a period, and the initial indoor environment temperature at the beginning of m continuous periods is obtained; and if the continuous m initial indoor environment temperatures are sequentially increased, the value of the operation time length influence value is the difference value between the current value and the preset compensation value.
