The object of the present invention is to provide a kind of control method of air-conditioner, by real time temperature Tw outside sensing chamber and indoor real time temperature Tn, adjust at any time the operational factor of air-conditioner, can meet the demand of user's refrigerating/heating, improving the user experiences, can reduce the power consumption of air-conditioner again, realize energy-conserving and environment-protective.

Embodiment one:

Fig. 1 is the realization flow figure of the air-conditioner control method that provides of first embodiment of the invention; For convenience of explanation, only show the part relevant to the present embodiment, as shown in the figure:

In step S11, control air-conditioner and enter the energy conservation pattern.

In air-conditioner control method provided by the invention, this step is steps necessary.After the user opens air-conditioner, the mode of operation that air-conditioner enters refrigeration or heats, the target temperature Tm that at first according to the user, sets normally moves.After default a period of time of air-conditioner operation, automatically enter the energy conservation pattern; Perhaps under user's selection operation, air-conditioner enters the energy conservation pattern.

In step S12, obtain outdoor real time temperature Tw and indoor real time temperature Tn.

In this step, controller obtains outdoor real time temperature Tw and indoor real time temperature Tn by outdoor temperature sensor and indoor temperature transmitter respectively.

In step S13, judge the size of described outdoor real time temperature Tw and default outdoor temperature threshold value Ty.

In this step, controller need to compare outdoor real time temperature Tw and default outdoor temperature threshold value Ty, the judgement size.When outdoor temperature threshold value Ty that should be default is dispatched from the factory by producer, setting or user independently set., as preferably, can, according to the difference of air conditioner refrigerating and heating mode, set respectively outdoor temperature threshold value Ty.For example, under refrigeration mode, outdoor temperature threshold value Ty is 35 ℃; Under heating mode, outdoor temperature threshold value Ty is 20 ℃, etc.

In step S14, under refrigeration mode, described outdoor real time temperature Tw is during less than default outdoor temperature threshold value Ty, perhaps under heating mode, described outdoor real time temperature Tw is during greater than default outdoor temperature threshold value Ty, to control air-conditioner be indoor real time temperature Tn according to target temperature T1 moves with the mode of default temperature difference △ Ts sum.

In this step, the work that needs the difference air-conditioner is for refrigeration or heats to carry out.Under refrigeration mode, as outdoor real time temperature Tw during less than default outdoor temperature threshold value Ty, to control air-conditioner be indoor real time temperature Tn according to target temperature T1 moves with the mode of default temperature difference △ Ts sum.Under heating mode, as outdoor real time temperature Tw during greater than default outdoor temperature threshold value Ty, controlling air-conditioner is that indoor real time temperature Tn moves with the mode of the temperature difference △ Ts sum of presetting according to target temperature T1, i.e. the realistic objective temperature of air-conditioner operation is modified to T1=Tn+ △ Ts.What need to draw attention to is that under refrigeration mode, default temperature difference △ Ts is negative; Under heating mode, default temperature difference △ Ts is positive number.And when default temperature difference △ Ts is dispatched from the factory by producer, setting or user independently set, generally, 0.5 ℃≤| △ TS|≤10 ℃.Further, use the comfortableness of air-conditioner in order to take into full account the user, the preferred value of default temperature difference △ Ts be 0.5 ℃≤| △ TS|≤3 ℃, even in 1 ℃, less interval≤| within △ TS|≤2 ℃.

Embodiment two:

Fig. 2 is the realization flow figure of the air-conditioner control method that provides of second embodiment of the invention; For convenience of explanation, also only show the part relevant to the present embodiment, as shown in the figure:

In step S21, control air-conditioner and enter the energy conservation pattern.

In step S22, obtain outdoor real time temperature Tw and indoor real time temperature Tn.

In step S23, judge the size of described outdoor real time temperature Tw and default outdoor temperature threshold value Ty.

In step S24, under refrigeration mode, described outdoor real time temperature Tw is during less than default outdoor temperature threshold value Ty, perhaps under heating mode, described outdoor real time temperature Tw is during greater than default outdoor temperature threshold value Ty, to control air-conditioner be indoor real time temperature Tn according to target temperature T1 moves with the mode of default temperature difference △ Ts sum.

Only, the control method that the method that this second embodiment provides and the first embodiment provide is identical from above-mentioned step S21 to step S24, and difference is: the control method that this second embodiment provides is further comprising the steps of:

In step S25, under refrigeration mode, described outdoor real time temperature Tw is during more than or equal to default outdoor temperature threshold value Ty, perhaps under heating mode, when described outdoor real time temperature Tw is less than or equal to default outdoor temperature threshold value Ty, the mode that to control air-conditioner be former design temperature Tm according to target temperature T1 is moved.

This step is the same with step S24, is all that certain result of comparing take outdoor real time temperature Tw and default outdoor temperature threshold value Ty is as prerequisite.Under refrigeration mode, as outdoor real time temperature Tw, during more than or equal to default outdoor temperature threshold value Ty, control air-conditioner and move according to former design temperature Tm; Perhaps under heating mode, when outdoor real time temperature Tw is less than or equal to default outdoor temperature threshold value Ty, controls air-conditioner and move according to former design temperature Tm.

That is to say, the control method of the air-conditioner that this second embodiment provides, use the comfortableness of air-conditioner in order to take into full account the user, summer outdoor real time temperature very high, while exceeding outdoor temperature threshold value Ty, perhaps in very low, the situation lower than outdoor temperature threshold value Ty of outdoor real time temperature in winter, pay the utmost attention to user's comfortableness demand, control air-conditioner and move according to the mode that target temperature T1 equals the temperature T m of the former setting of user.After outdoor real time temperature variation, then, according to the outdoor real time temperature parameter that gets and outdoor temperature threshold value Ty result relatively, control air-conditioner and move with the mode of the temperature difference △ Ts sum of presetting take target temperature T1 as indoor real time temperature Tn.

Fig. 3 is the air-conditioner control method that provides according to the second embodiment under refrigeration mode, the change curve of each temperature parameter of realization.Referring to Fig. 3, default outdoor temperature threshold value Ty replaces with two parallel dotted lines respectively with former design temperature Tm.

Within the time period from 0 to t1, the outdoor real time temperature Tw that outdoor temperature sensor detects is all the time less than default outdoor temperature threshold value Ty, and the target temperature T1 of air-conditioner is that indoor real time temperature Tn is negative with default temperature difference △ Ts(△ Ts) sum;

From t1 to t2 during this period of time in, the outdoor real time temperature Tw that outdoor temperature sensor detects is greater than or equal to default outdoor temperature threshold value Ty's, air-conditioner just moves according to former design temperature Tm, that is to say, the target temperature T1 of this moment is former design temperature Tm;

After having surpassed time point t2, the outdoor real time temperature Tw that outdoor temperature sensor detects in real time is again all the time less than default outdoor temperature threshold value Ty, at this moment, air-conditioner is automatic adjust operation parameter again, according to target temperature T1, is that indoor real time temperature Tn is negative with default temperature difference △ Ts(△ Ts) mode of sum moves.

As shown in Figure 3, in the running of air-conditioner, indoor temperature transmitter, outdoor temperature sensor be sensing chamber's internal and external temperature in real time, and pass to controller,, through contrast and judgement, the operational factor of air-conditioner is adjusted in real time, like this, both guarantee the demand of user's comfortableness, reached again the requirement of environmental protection and energy saving.

Embodiment three:

Fig. 4 is the realization flow figure of the air-conditioner control method that provides of third embodiment of the invention; For convenience of explanation, also only show the part relevant to the present embodiment, as shown in the figure:

In step S31, control air-conditioner and enter the energy conservation pattern.

In step S32, obtain outdoor real time temperature Tw and indoor real time temperature Tn.

In step S33, judge the size of described outdoor real time temperature Tw and default outdoor temperature threshold value Ty.

In step S34, under refrigeration mode, described outdoor real time temperature Tw is during less than default outdoor temperature threshold value Ty, perhaps under heating mode, described outdoor real time temperature Tw is during greater than default outdoor temperature threshold value Ty, to control air-conditioner be indoor real time temperature Tn according to target temperature T1 moves with the mode of default temperature difference △ Ts sum.

From above-mentioned step S31 to step S34 only, the method step that the 3rd embodiment provides is also identical with the control method step that the first embodiment provides, and difference just is, the control method that the 3rd embodiment provides is further comprising the steps of:

In step S35, judge the size of described target temperature T1 and former design temperature Tm.

In step S35, controller needs the further size of judgement, comparison object temperature T 1=Tn+ △ Ts and former design temperature Tm.Next, according to both comparative results, in conjunction with air-conditioner be operated under refrigeration mode or heating mode under enter the next step of controlling.

In step S36, under refrigeration mode, when described target temperature T1 is less than or equal to former design temperature Tm, perhaps under heating mode, described target temperature T1 is during more than or equal to former design temperature Tm, the mode that to control air-conditioner be former design temperature Tm according to target temperature T1 is moved.

When specific implementation, the default temperature difference likely appears | the situation that the numerical value of △ TS| is bigger than normal etc., so easily cause air-conditioner under refrigeration mode, through revised target temperature T1 also lower than former design temperature Tm, perhaps under heating mode, through revised target temperature T1 also higher than former design temperature Tm, at this moment, controller all can be controlled air-conditioner and move according to the predefined temperature T m of user, and namely target temperature T1 equals former design temperature Tm.Like this, both guarantee the demand of user's comfortableness, reached again the requirement of environmental protection and energy saving.

Embodiment four:

Fig. 5 is the realization flow figure of the air-conditioner control method that provides of fourth embodiment of the invention; For convenience of explanation, also only show the part relevant to the present embodiment, as shown in the figure:

In step S41, control air-conditioner and enter the energy conservation pattern.

In step S42, control air-conditioner high frequency operation in Preset Time.

In step S43, obtain outdoor real time temperature Tw and indoor real time temperature Tn.

In step S44, judge the size of described outdoor real time temperature Tw and default outdoor temperature threshold value Ty.

In step S45, under refrigeration mode, described outdoor real time temperature Tw is during less than default outdoor temperature threshold value Ty, perhaps under heating mode, described outdoor real time temperature Tw is during greater than default outdoor temperature threshold value Ty, to control air-conditioner be indoor real time temperature Tn according to target temperature T1 moves with the mode of default temperature difference △ Ts sum.

In the present embodiment, after air-conditioner enters the energy conservation pattern, in order to make air-conditioner, reach fast the goal-setting temperature, first control compressor high frequency operation in preset time t.This default time t can be set by producer when air-conditioner dispatches from the factory, also can be by the needs of user according to self, and autonomous the setting.Generally, as preferred embodiment, the span of preset time t was good between 0.5 minute to 30 minutes.

After high frequency operation Preset Time, then enter next step S43: by controller, obtain outdoor real time temperature Tw and indoor real time temperature Tn by outdoor temperature sensor and indoor temperature transmitter respectively.Ensuing method step again, with the first embodiment is identical, at this, just no longer does and repeats.

Describe below by the control method of two concrete operational instances to air-conditioner provided by the invention.

At first, take summer the air-conditioner refrigerating operaton as example.Suppose default outdoor temperature threshold value Ty=33 ℃, target setting temperature difference △ TS=-1 ℃.After air-conditioner was opened, the operating temperature that the user sets was Tm=20 ℃, when the user needs air-conditioner power saving operation, selected to enter the energy conservation pattern.This moment indoor temperature transmitter indoor real time temperature to be detected be Tn=29 ℃, it is 32 ℃ (less than outdoor temperature threshold value Ty=33 ℃) that outdoor temperature sensor detects outdoor real time temperature Tw, controller is controlled air-conditioning according to T1=Tn+ △ Ts, i.e. T1=28 ℃ of operation.For making indoor fast cooling, the first high frequency running refrigerating of air-conditioner 5 minutes, then according to T1=28 ℃ of operation.

Especially, during the outdoor real time temperature Tw that obtains when daytime 〉=33 ℃, because outdoor temperature is higher, room refrigerating capacity demand increases, and this moment, air-conditioner was just according to former design temperature Tm=20 ℃ operation.And if to night, when outdoor real time temperature was reduced to Tw≤30 ℃, room refrigerating capacity demand reduced, air-conditioner is indoor real time temperature Tn and default temperature difference △ Ts sum operation according to target temperature T1.That is, if this moment indoor temperature transmitter indoor real time temperature to be detected be Tn=29 ℃, the target temperature difference △ TS=-1 ℃ of former setting, controller is controlled air-conditioner according to T1=Tn+ △ Ts, i.e. T1=28 ℃ of operation.

On the other hand, if the target temperature difference △ TS that the user sets is excessive, for example in these cases, user's target setting temperature difference △ TS is-5 ℃, as indoor temperature Tn during lower than 25 ℃, under the energy conservation pattern, target temperature T1 will be also lower than former design temperature Tm=20 ℃.In order to take into full account effect energy-conservation and that comfortableness is laid equal stress on, air-conditioner is according to former design temperature Tm=20 ℃ operation.When indoor real time temperature Tn is greater than or equal to 25 ℃, be that indoor real time temperature Tn moves with default temperature difference △ Ts sum according to target temperature T1 again.

Second operational instances, with winter air conditioner heat-production operate to example.Suppose default outdoor temperature threshold value Ty=10 ℃, target setting temperature difference △ TS=2 ℃.After air-conditioner was opened, the operating temperature that the user sets was Tm=25 ℃, when the user needs air-conditioner power saving operation, selected to enter the energy conservation pattern.This moment indoor temperature transmitter indoor real time temperature to be detected be Tn=15 ℃, it is 12 ℃ (greater than outdoor temperature threshold value Ty=10 ℃) that outdoor temperature sensor detects outdoor real time temperature, controller is controlled air-conditioning according to T1=Tn+ △ Ts, i.e. T1=17 ℃ of operation.For making indoor being rapidly heated, air-conditioner can first high frequency operation heat 5 minutes, then according to T1=17 ℃ of operation.

Especially, during less than 10 ℃, because outdoor temperature is lower, room heating capacity demand increases as outdoor real time temperature Tw, and this moment, air-conditioner was according to former design temperature Tm=25 ℃ operation.And if outdoor real time temperature is while being increased to Tw more than or equal to 10 ℃, room heating capacity demand reduces, and is indoor real time temperature Tn and default temperature difference △ Ts sum operation according to target temperature T1 again.

Same, if the target temperature difference △ TS that the user sets is excessive, for example in these cases, user's target setting temperature difference △ TS is 5 ℃, as indoor temperature Tn during higher than 20 ℃, under the energy conservation pattern, target temperature T1 will be also higher than former design temperature Tm=25 ℃.In order to take into full account effect energy-conservation and that comfortableness is laid equal stress on, air-conditioner is still according to former design temperature Tm=25 ℃ operation.As indoor real time temperature Tn during less than 20 ℃, be indoor real time temperature Tn and default temperature difference △ Ts sum operation according to target temperature T1 again.

Control method according to air-conditioner provided by the invention, can be according to user's comfortableness demand, by real-time detection outdoor environment temperature and indoor temperature, automatically adjust at any time the operational factor of air-conditioner, avoid user's operating air conditioner device continually, temperature is controlled under the optimal comfort state, the demand that can meet user's refrigeration and heat, simultaneously again can using electricity wisely, realize environmental protection.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, although with reference to previous embodiment, the present invention has been carried out more detailed explanation, for a person skilled in the art, it still can be modified or part technical characterictic wherein is equal to replacement the technical scheme that aforementioned each embodiment puts down in writing.All any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
