The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
With reference to Fig. 1, self-adaptation control method first embodiment of air-conditioner of the present invention is proposed.The self-adaptation control method of the air-conditioner of this embodiment comprises:
Step S100, set in advance outdoor environment temperature and the mapping relations that heat threshold value △ t1 and refrigeration threshold value △ t2, wherein △ t2〉△ t1, and heat threshold value △ t1 and refrigeration threshold value △ t2 diminishes along with the rising of outdoor environment temperature;
Among one embodiment, these mapping relations can be relation table, and the temperature range of outdoor environment temperature namely is set earlier, then corresponding setting of each temperature range are heated threshold value and refrigeration threshold value, and are as shown in table 1 below.
Corresponding threshold value and the refrigeration threshold value of heating of the temperature range of table 1. outdoor environment temperature
Above table 1 only is example, can be as the case may be and to the refrigeration threshold value and heat threshold value and arrange flexibly.When detecting outdoor environment temperature, then can determine the segment at this outdoor environment place earlier, and the search relationship table and obtain this outdoor environment temperature correspondence heat threshold value and the refrigeration threshold value.For example, if current detected outdoor environment temperature T2 is 20 ℃, then according to last table 1 as can be known the threshold value △ t1 that heats of this outdoor environment temperature correspondence be-0.5 ℃, the refrigeration threshold value △ t2 of correspondence is 3.5 ℃.
Among another embodiment, continuous outdoor environment temperature is set earlier, and then outdoor environment temperature is set and heat threshold value, the refrigeration threshold value is specific relation, for example linearity or curved line relation.This specific relation can arrange as the case may be.Be example with the curved line relation, shown in Fig. 2 a and Fig. 2 b, outdoor environment temperature and heat curve relation figure between threshold value, the refrigeration threshold value.Shown in Fig. 2 a, when outdoor environment temperature T2＜15 ℃, heat 2 ℃ of threshold values △ t1=, when 15 ℃≤T2 of outdoor environment temperature≤18 ℃, heat threshold values △ t1=2-5* (T2-15)/3 ℃; When outdoor environment temperature T2＞15 ℃, heat threshold values △ t1=-3 ℃.Shown in Fig. 2 b, when outdoor environment temperature T2＜5 ℃, 5 ℃ of refrigeration threshold values △ t2=, when 5 ℃≤T2 of outdoor environment temperature≤20 ℃, refrigeration threshold values △ t2=5-0.4*(T2-5) ℃; When outdoor environment temperature T2＞20 ℃, t2=-1 ℃ of refrigeration threshold values △.Last relatively embodiment, the value that heats threshold values △ t1 and refrigeration threshold values △ t2 of the air-conditioner of this embodiment is to become continuous particular kind of relationship with outdoor environment temperature, for example linear relationship or curved line relation etc.This outdoor environment temperature correspondence heat threshold value and the refrigeration threshold value is more accurate, further improved the efficient of self-adapting operation.
In above-described embodiment, the described threshold value that heats is :-6 ℃≤△ t1≤5 ℃, described refrigeration threshold value is :-5 ℃≤△ t2≤8 ℃.
Step S110, after air-conditioner enters the self-adapting operation pattern, detect environment temperature and obtain when instruction, obtain the indoor and outdoor surroundings temperature;
In indoor and outdoor corresponding temperature sensor is set, for detection of the environment temperature of indoor and outdoor.This temperature sensor is the inside and outside environment temperature of sensing chamber in real time, then storage; Also can receive the instruction of controller, after the environment temperature inside and outside the sensing chamber, transmit back controller.This environment temperature is obtained instruction and can be sent for the user, is used for obtaining indoor and outdoor surroundings temperature or the control temperature sensor that temperature sensor detects and carries out the detection of the environment temperature of indoor and outdoor.Certainly, this environment temperature is obtained instruction also can pass through the timer triggering for generating, can also produce in real time.The detection of the environment temperature of this indoor and outdoor can be carried out simultaneously, also can successively carry out.Do not limit at this.
The outdoor environment temperature that step S120, basis set in advance and the mapping relations that heat threshold value and refrigeration threshold value obtain heat threshold value △ t1 and freeze threshold value △ t2 corresponding with the outdoor environment temperature that obtains;
After getting access to outdoor environment temperature, can be according to aforesaid outdoor environment temperature and the mapping relations that heat threshold value and refrigeration threshold value, what obtain current outdoor environment temperature correspondence heats threshold value and the threshold value of freezing.
Step S130, obtain the target temperature that the user sets, calculate the difference △ T of the target temperature that obtains described indoor environment temperature and user's setting, and with this difference △ T and describedly heat threshold value △ t1, refrigeration threshold value △ t2 compares, and determine the actual motion pattern of air-conditioner according to comparative result, the control air-conditioner is with described actual motion mode operation;
Obtain described outdoor environment temperature correspondence heat threshold value △ t1 and refrigeration threshold value △ t2 after, then obtain the target temperature Ts that the user sets, calculate the difference △ T that obtains the target temperature Ts that described indoor environment temperature T1 and user set.Then with this difference △ T with heat threshold value △ t1, refrigeration threshold value △ t2 compares, and determines the actual motion pattern of air-conditioner according to comparative result.Be specially: as △ T during greater than refrigeration threshold value △ t2, the actual motion pattern of determining air-conditioner is refrigeration mode; When △ T when heating threshold value △ t1, the actual motion pattern of determining air-conditioner is heating mode; When △ T more than or equal to heating threshold value △ t1, and △ T is when being less than or equal to refrigeration threshold value △ t2, the actual motion pattern of determining air-conditioner is air supply pattern.
In addition, when determining the actual motion pattern of air-conditioner, the mode and gear of the grade correspondence of the grade of the difference of the target temperature that can also set according to described indoor environment temperature and user and the difference that sets in advance is determined the operational taps of the actual motion pattern of air-conditioner.For example, the indoor environment temperature of current detection is 40 ℃, and the target temperature that the user sets is 26 ℃, and then both temperature gaps are 14 ℃, when the actual motion pattern of determining air-conditioner according to said method is refrigeration mode, can also control air-conditioner according to forcing cold mode operation; If the indoor environment temperature of current detection is 34 ℃, then when the actual motion pattern of determining air-conditioner according to said method is refrigeration mode, can also control air-conditioner according to the standard mode operation that freezes; If the indoor environment temperature of current detection is 29 ℃, then when the actual motion pattern of determining air-conditioner according to said method is refrigeration mode, can also controls air-conditioner and move according to weak refrigeration mode.Aforementioned only is example, does not limit the scope of its technical scheme.The mode and gear of the grade correspondence of the difference that sets in advance can be as the case may be needs and arrange flexibly.By according to the difference situation between the target temperature of indoor environment temperature and setting, select and the strong and weak degree of operational mode is carried out adaptability, thereby not only can reach the demand of the target temperature that the user sets fast, but also reach the effect of energy saving.
In step S140, the running, whether receive air-conditioner self-adapting operation pattern exit instruction; When receiving this exit instruction, then finish the Self Adaptive Control flow process; When not receiving this exit instruction, then after arriving running time, return and change step S110 over to.
This air-conditioner self-adapting operation pattern exit instruction can be the pattern switching command of user's triggering, the shutdown command of air-conditioner.Certainly the shutdown command in the time of can also cutting off the power supply automatically for air-conditioner, the shutdown command when perhaps the Self Adaptive Control time of user's setting arrives.When not receiving this self-adapting operation pattern exit instruction, then can obtain when instruction detecting environment temperature, return step S110, dynamically to adjust the actual motion pattern of air-conditioner according to the indoor and outdoor surroundings variation of temperature, improve the self adaptation efficient of air-conditioner.
To come the control procedure of specification self-adapting operation pattern with an instantiation below.
When air-conditioner enters the self-adapting operation pattern, then detect indoor environment temperature.Current outdoor environment temperature T2 is 4 ℃, and current indoor environment temperature T1 is 32 ℃.And, know that the target temperature Ts that the user sets is 26 ℃.According to the lookup table mode among the step S120, what can obtain current outdoor environment temperature T2 correspondence heats t1=2 ℃ of threshold value △, t2=5 ℃ of refrigeration threshold value △.Then, calculate target temperature Ts that current indoor environment temperature T1 and user set difference △ T=T1-Ts=6 ℃, and this △ T＞△ t2, so current air-conditioner move according to refrigeration mode, to reduce indoor environment temperature.In the running time (for example t=10 minute) of refrigeration mode, if do not receive air-conditioner self-adapting operation pattern exit instruction, air-conditioner is then always according to current refrigerating operaton pattern.When arrive in the running time of refrigeration mode, sensing chamber's internal and external environment temperature again then, current indoor environment temperature drops to 30 ℃, and outdoor environment temperature T2 still is 4 ℃, and then its correspondence heats t1=2 ℃ of threshold value △, t2=5 ℃ of refrigeration threshold value △.This moment, accounting temperature difference △ was T=T1-Ts=4 ℃, and this △ T is between △ t1 and △ t2, so this moment, air-conditioner moved according to air supply pattern, be equivalent to stop in advance refrigeration, rely on outdoor low temperature radiation and crack between a door and its frame to transmit cold to indoor then, play the effect of energy saving, and indoor environment temperature will continue also to descend.When arrive in the running time of air supply pattern correspondence, detect current indoor and outdoor surroundings temperature again, current indoor environment temperature T1=25 ℃, outdoor environment temperature T2 still is 2 ℃, then its correspondence heats t1=2 ℃ of threshold value △, t2=5 ℃ of refrigeration threshold value △.This moment T=T1-Ts=-1 ℃ of △, and this △ T＜△ t1 so air-conditioner carries out according to heating mode, remedying the cold that the outdoor temperature transmission is come in, thereby reaches the effect of constant temperature, improves self adaptation efficient.
In addition, owing to above-mentioned heat threshold value △ t1 and the refrigeration threshold value △ t2 that sets in advance diminishes along with the rising of outdoor environment temperature, be that outdoor environment temperature is more high, its correspondence heat threshold value △ t1 and refrigeration threshold value △ t2 is more little, so the switching between heating mode, air supply pattern and the refrigeration mode is more prone to.When the operational mode of air-conditioner is heating mode, if outdoor environment temperature is more high, it is then more little to heat threshold value △ t1, can accelerate heating mode thus to the switching of air supply pattern, thereby make outdoor high temperature radiation can transmit heat to indoor, accelerate the adjusting of indoor environment temperature; When the operational mode of air-conditioner is refrigeration mode, if outdoor environment temperature is more low, refrigeration threshold value △ t2 is then more big, can accelerate refrigeration mode thus to the switching of air supply pattern, thereby make outdoor low temperature radiation can transmit cold to indoor, accelerate the adjusting of indoor environment temperature.
The control method of the self-adapting operation pattern that present embodiment adopts, by sensing chamber's internal and external environment temperature, and according to the difference △ T of the target temperature Ts of indoor environment temperature T1 and setting, and outdoor environment temperature T2 correspondence set in advance heat threshold value △ t1, refrigeration threshold value △ t2, relatively determine the actual motion pattern of air-conditioner, thereby make when indoor environment temperature T1 exceeds refrigeration threshold value △ t2 than the target temperature Ts that sets, air-conditioner moves according to refrigeration mode, when △ T is between △ t1 and △ t2, just stop refrigeration in advance, and rely on outdoor low temperature to transmit cold to indoor, further reduce indoor environment temperature again, thereby stop the air-conditioner refrigeration in advance, reduce refrigeration, play in advance the effect of brake, prevent that indoor environment temperature from dropping to low and cause the adjustment effect undesirable, further improves the efficient of self-adapting operation.In addition, above-mentioned control method can either play the demand that comparatively fast reaches user's design temperature, also can play the effect of energy saving.When temperature indoor environment temperature T1 hanged down when heating threshold value than Ts, air-conditioner moves according to heating mode, as △ T during less than △ t1, to continue the control air-conditioner moves according to heating mode, to remedy bigger hot-fluid vector, make indoor environment temperature can further rise to user's design temperature demand, improve the efficient of self-adapting operation.
With reference to Fig. 3, on the basis of above-mentioned first embodiment, self-adaptation control method second embodiment of air-conditioner is proposed also.Among this embodiment, after above-mentioned steps S130, also comprise:
Step S150, judge whether the actual motion pattern of air-conditioner is air supply pattern; When the actual motion pattern of air-conditioner is air supply pattern, then change step S160 over to; When the actual motion pattern of air-conditioner is not air supply pattern, then change step S140 over to;
Step S160, judge that target temperature that the user sets whether between the indoor environment temperature that detects and outdoor environment temperature, is then to change step S170 over to; Otherwise change step S140 over to;
Step S170, control air refreshing device start, and change step S140 over to.
When the actual motion pattern of air-conditioner is air supply pattern, can also be by the unlatching of air refreshing device, indoor importing than the lower outdoor airflow of indoor environment temperature or the air-flow more higher than indoor environment temperature, thus the regulations speed of indoor environment temperature accelerated.For example, when outdoor environment temperature T2 is lower than the target temperature Ts that sets, and indoor environment temperature T1 utilizes air refreshing device to reduce indoor environment temperature T1 when higher than the target temperature Ts that sets.When outdoor environment temperature T2 than the target temperature Ts height of setting, and indoor environment temperature T1 utilizes air refreshing device to improve indoor environment temperature T1 when lower than the target temperature Ts that sets.
Method with aforementioned first embodiment is example, and current indoor environment temperature drops to 30 ℃, and outdoor environment temperature T2 still is 4 ℃, and then its correspondence heats t1=2 ℃ of threshold value △, t2=5 ℃ of refrigeration threshold value △.This moment, accounting temperature difference △ was T=T1-Ts=4 ℃, and this △ T so this moment, air-conditioner moved according to air supply pattern, is equivalent to stop in advance refrigeration between △ t1 and △ t2.Because the operational mode of current air-conditioner is air supply pattern, judge simultaneously the target temperature Ts of current outdoor environment temperature T2＜setting again, and the target temperature Ts of indoor environment temperature T1＞setting, open air refreshing device simultaneously, indoor to utilize air refreshing device that outdoor low temperature is imported, and rely on outdoor low temperature radiation and crack between a door and its frame to transmit cold to indoor, can reduce indoor environment temperature faster, not only improve the regulations speed of indoor temperature, but also play the effect of energy saving.
Among another embodiment, when current outdoor environment temperature T2 was 25 ℃, according to the mode of query relation table 1, what obtain outdoor environment temperature T2 correspondence heated t1=-3.5 ℃ of threshold value △, t2=0 ℃ of refrigeration threshold value △.If current indoor environment temperature T1 is 17 ℃, when the target temperature Ts that the user sets is 21 ℃, calculate T=T1-Ts=-4 ℃ of the temperature gap △ that obtains both, and this △ T＜△ t2, so air-conditioner moves according to heating mode, to improve indoor environment temperature.In the running time of heating mode, if when not receiving self-adapting operation pattern exit instruction, air-conditioner will move according to the heating operation pattern always.When reach the running time of heating mode, detect indoor environment temperature T1 and rise to 18 ℃, outdoor environment temperature T2 still is 25 ℃, then its correspondence heats t1=-3.5 ℃ of threshold value △, t2=0 ℃ of refrigeration threshold value △.Calculate to obtain T=T1-Ts=-3 ℃ of temperature gap △ this moment, and △ T is between △ t1 and △ t2, so air-conditioner moves according to air supply pattern.Because the operational mode of current air-conditioner is air supply pattern, judge simultaneously the target temperature Ts of current outdoor environment temperature T2＞setting again, and the target temperature Ts of indoor environment temperature T1＜setting, so in air-conditioner operation air supply pattern, can also start air refreshing device, utilize air refreshing device to import outdoor high temperature indoor, and rely on outdoor high temperature radiation and crack between a door and its frame to transmit heat to indoor, can improve indoor environment temperature faster, not only improve the regulations speed of indoor temperature, but also play the effect of energy saving.
With reference to Fig. 4, corresponding said method embodiment, an embodiment of the adaptive controller of a kind of air-conditioner of proposition the present invention.The adaptive controller of the air-conditioner of this embodiment can independently arrange, and also can be arranged in the air-conditioner, also can be arranged in the remote controller equipment.The adaptive controller of this air-conditioner comprises:
Threshold value arranges module 100, is used for setting in advance outdoor environment temperature and the mapping relations that heat threshold value △ t1 and refrigeration threshold value △ t2, wherein △ t2〉△ t1;
Heat threshold value refrigeration threshold value acquisition module 120, be used for obtaining heat threshold value △ t1 and freeze threshold value △ t2 corresponding with the outdoor environment temperature that obtains according to the outdoor environment temperature that sets in advance and the mapping relations that heat threshold value and refrigeration threshold value;
Operational mode determination module 130, be used for obtaining the target temperature that the user sets, calculate the difference △ T of the target temperature that obtains described indoor environment temperature and user's setting, and with this difference △ T and describedly heat threshold value △ t1, refrigeration threshold value △ t2 compares, and determine the actual motion pattern of air-conditioner according to comparative result, the control air-conditioner is with described actual motion mode operation;
Wherein, as △ T〉during △ t2, the actual motion pattern of determining air-conditioner is refrigeration mode;
When △ t1≤△ T≤△ t2, the actual motion pattern of determining air-conditioner is air supply pattern;
When △ T＜△ t1, the actual motion pattern of determining air-conditioner is heating mode.
The concrete setting up procedure that threshold value arranges 100 pairs of mapping relations of module just repeats no more at this as described in the previous methods embodiment.In indoor and outdoor corresponding temperature sensor is set, for detection of the environment temperature of indoor and outdoor.Temperature acquisition module 110 then can be for being arranged on the temperature sensor of indoor and outdoor, be used for detecting environment temperature when obtaining instruction, sensing chamber's internal and external environment temperature, and transmit it to and heat threshold value refrigeration threshold value acquisition module 120 and operational mode determination module 130.Certainly, this temperature acquisition module 110 also can be the module that connects with temperature sensor, be used for detecting environment temperature when obtaining instruction, obtain the inside and outside environment temperature of environment temperature or control temperature sensor sensing chamber of the detected indoor and outdoor of temperature sensor.The detection of the environment temperature of this indoor and outdoor can be carried out simultaneously, also can successively carry out.This environment temperature is obtained instruction and can be sent for the user, is used for obtaining indoor and outdoor surroundings temperature or the control temperature sensor that temperature sensor detects and carries out the detection of the environment temperature of indoor and outdoor.Certainly, this environment temperature is obtained instruction also can pass through the timer triggering for generating, can also produce in real time.
Heat threshold value refrigeration threshold value acquisition module 120 and receive the outdoor environment temperature that obtains, then according to setting in advance outdoor environment temperature and heat threshold value, the mapping relations of refrigeration between the threshold value, coupling obtain this outdoor environment temperature correspondence heat threshold value, the threshold value of freezing.
Obtain described outdoor environment temperature correspondence heat threshold value △ t1 and refrigeration threshold value △ t2 after, then operational mode determination module 130 obtains the target temperature Ts that the user sets, and calculates the difference △ T of the target temperature Ts that obtains described indoor environment temperature T1 and user's setting.Then with this difference △ T with heat threshold value △ t1, refrigeration threshold value △ t2 compares, and determines the actual motion pattern of air-conditioner according to comparative result.Be specially: as △ T during greater than refrigeration threshold value △ t2, the actual motion pattern of determining air-conditioner is refrigeration mode; When △ T when heating threshold value △ t1, the actual motion pattern of determining air-conditioner is heating mode; When △ T more than or equal to heating threshold value △ t1, and △ T is when being less than or equal to refrigeration threshold value △ t2, the actual motion pattern of determining air-conditioner is air supply pattern.Can equate the running time of above-mentioned refrigeration mode, heating mode and air supply pattern, also can be unequal.And three's running time can be as the case may be needs and arrange flexibly.Do not limit at this.
In addition, when determining the actual motion pattern of air-conditioner, the mode and gear of the grade correspondence of the grade of the difference of the target temperature that operational mode determination module 130 can also be set according to described indoor environment temperature and user and the difference that sets in advance is determined the operational taps of the actual motion pattern of air-conditioner.For example, the indoor environment temperature of current detection is 40 ℃, and the target temperature that the user sets is 26 ℃, and then both temperature gaps are 14 ℃, when the actual motion pattern of determining air-conditioner according to said method is refrigeration mode, can also control air-conditioner according to forcing cold mode operation; If the indoor environment temperature of current detection is 34 ℃, then when the actual motion pattern of determining air-conditioner according to said method is refrigeration mode, can also control air-conditioner according to the standard mode operation that freezes; If the indoor environment temperature of current detection is 29 ℃, then when the actual motion pattern of determining air-conditioner according to said method is refrigeration mode, can also controls air-conditioner and move according to weak refrigeration mode.Aforementioned only is example, does not limit the scope of its technical scheme.The mode and gear of the grade correspondence of the difference that sets in advance can be as the case may be needs and arrange flexibly.By according to the difference situation between the target temperature of indoor environment temperature and setting, select and the strong and weak degree of operational mode is carried out adaptability, thereby not only can reach the demand of the target temperature that the user sets fast, but also reach the effect of energy saving.
If in the running time of the actual motion pattern of air-conditioner, when receiving air-conditioner self-adapting operation pattern exit instruction, then withdraw from the self-adapting operation pattern, if do not receive air-conditioner self-adapting operation pattern exit instruction, then continue to keep the actual motion mode operation.To be detectedly obtain when instruction to environment temperature, temperature acquisition module 110 carries out obtaining of indoor and outdoor surroundings temperature again.This air-conditioner self-adapting operation pattern exit instruction can be the pattern switching command of user's triggering, the shutdown command of air-conditioner.Certainly the shutdown command in the time of can also cutting off the power supply automatically for air-conditioner, the shutdown command when perhaps the Self Adaptive Control time of user's setting arrives.
The control method of the self-adapting operation pattern that present embodiment adopts, by sensing chamber's internal and external environment temperature, and according to the difference △ T of the target temperature Ts of indoor environment temperature T1 and setting, and outdoor environment temperature T2 correspondence set in advance heat threshold value △ t1, refrigeration threshold value △ t2, relatively determine the actual motion pattern of air-conditioner, thereby make when indoor environment temperature T1 exceeds refrigeration threshold value △ t2 than the target temperature Ts that sets, air-conditioner moves according to refrigeration mode, when △ T is between △ t1 and △ t2, just stop refrigeration in advance, and rely on outdoor low temperature to transmit cold to indoor, further reduce indoor environment temperature again, thereby stop the air-conditioner refrigeration in advance, reduce refrigeration, play in advance the effect of brake, prevent that indoor environment temperature from dropping to low and cause the adjustment effect undesirable, further improves the efficient of self-adapting operation.In addition, above-mentioned control method can either play the demand that comparatively fast reaches user's design temperature, also can play the effect of energy saving.When temperature indoor environment temperature T1 hanged down when heating threshold value than Ts, air-conditioner moves according to heating mode, as △ T during less than △ t1, to continue the control air-conditioner moves according to heating mode, to remedy bigger hot-fluid vector, make indoor environment temperature can further rise to user's design temperature demand, improve the efficient of self-adapting operation.
With reference to Fig. 5, on the basis of the device of above-mentioned first embodiment, adaptive controller second embodiment of air-conditioner is proposed also.The adaptive controller of this air-conditioner also comprises:
Renew wind control module 140, being used for determining the actual motion pattern of air-conditioners when described operational mode determination module 130 is between the indoor environment temperature that detecting of target temperature that air supply pattern and user set and the outdoor environment temperature time, then controls the air refreshing device startup.
When the actual motion pattern of air-conditioner is air supply pattern, can also be by the unlatching of air refreshing device, indoor importing than the lower outdoor airflow of indoor environment temperature or the air-flow more higher than indoor environment temperature, thus the regulations speed of indoor environment temperature accelerated.For example, when outdoor environment temperature T2 is lower than the target temperature Ts that sets, and indoor environment temperature T1 utilizes air refreshing device to reduce indoor environment temperature T1 when higher than the target temperature Ts that sets.When outdoor environment temperature T2 than the target temperature Ts height of setting, and indoor environment temperature T1 utilizes air refreshing device to improve indoor environment temperature T1 when lower than the target temperature Ts that sets.
Method with aforementioned first embodiment is example, and current indoor environment temperature drops to 30 ℃, and outdoor environment temperature T2 still is 4 ℃, and then its correspondence heats t1=2 ℃ of threshold value △, t2=5 ℃ of refrigeration threshold value △.This moment, accounting temperature difference △ was T=T1-Ts=4 ℃, and this △ T so this moment, air-conditioner moved according to air supply pattern, is equivalent to stop in advance refrigeration between △ t1 and △ t2.Because the operational mode of current air-conditioner is air supply pattern, judge simultaneously the target temperature Ts of current outdoor environment temperature T2＜setting again, and the target temperature Ts of indoor environment temperature T1＞setting, open air refreshing device simultaneously, indoor to utilize air refreshing device that outdoor low temperature is imported, and rely on outdoor low temperature radiation and crack between a door and its frame to transmit cold to indoor, can reduce indoor environment temperature faster, not only improve the regulations speed of indoor temperature, but also play the effect of energy saving.
Among another embodiment, when current outdoor environment temperature T2 was 25 ℃, according to the mode of query relation table 1, what obtain outdoor environment temperature T2 correspondence heated t1=-3.5 ℃ of threshold value △, t2=0 ℃ of refrigeration threshold value △.If current indoor environment temperature T1 is 17 ℃, when the target temperature Ts that the user sets is 21 ℃, calculate T=T1-Ts=-4 ℃ of the temperature gap △ that obtains both, and this △ T＜△ t2, so air-conditioner moves according to heating mode, to improve indoor environment temperature.In the running time of heating mode, if when not receiving self-adapting operation pattern exit instruction, air-conditioner will move according to the heating operation pattern always.When reach the running time of heating mode, detect indoor environment temperature T1 and rise to 18 ℃, outdoor environment temperature T2 still is 25 ℃, then its correspondence heats t1=-3.5 ℃ of threshold value △, t2=0 ℃ of refrigeration threshold value △.Calculate to obtain T=T1-Ts=-3 ℃ of temperature gap △ this moment, and △ T is between △ t1 and △ t2, so air-conditioner moves according to air supply pattern.Because the operational mode of current air-conditioner is air supply pattern, judge simultaneously the target temperature Ts of current outdoor environment temperature T2＞setting again, and the target temperature Ts of indoor environment temperature T1＜setting, so in air-conditioner operation air supply pattern, can also start air refreshing device, utilize air refreshing device to import outdoor high temperature indoor, and rely on outdoor high temperature radiation and crack between a door and its frame to transmit heat to indoor, can improve indoor environment temperature faster, not only improve the regulations speed of indoor temperature, but also play the effect of energy saving.
