Brief description of the drawings
Fig. 1 is the flow chart of operation of air conditioner control method one embodiment of the present invention;
Fig. 2 is the flow chart of second embodiment of operation of air conditioner control method of the present invention.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below with reference to drawings and examples, The present invention is described in further detail.
Fig. 1 is referred to, the figure show the flow chart of operation of air conditioner control method one embodiment of the present invention.It is specific next Say, the embodiment refers to the operation control flow that automatic operation mode is first entered into after power-on of air conditioner.
As shown in figure 1, the operation control process of automatic operation mode is first entered into this embodiment, after power-on of air conditioner such as Under:
Step 101:Air-conditioning enters automatic operation mode.
The entrance of automatic operation mode, can be in different ways.For example, when air-conditioning dispatches from the factory, automatic operation mode is set It is set to the default mode of operation after air-conditioning is started shooting every time, power-on of air conditioner start, automatically into the automatic operation mode.It is or empty The control instruction for receiving user is adjusted, if control instruction is automatic operation mode, air-conditioning enters back into automatic operation mode.That is, Automatic operation mode is entered by user's control air-conditioning.
Step 102:Obtain outdoor real time temperature Tw, indoor real time temperature Tn and indoor design temperature Ts.
Outdoor real time temperature Tw can utilize outdoor temperature sensor detection, the detection by reading outdoor temperature sensor Signal and obtain, indoor real time temperature Tn can utilize indoor temperature transmitter detection, by reading indoor temperature transmitter Detection signal and obtain.Moreover, Tw and Tn is real-time temperature values, it is not changeless value.
For indoor design temperature Ts, in general, a default temperature value is provided with when air-conditioning dispatches from the factory as indoor setting Temperature Ts, such as, acquiescence Ts is 25 DEG C.When air-conditioning re-powers start every time, indoor design temperature Ts is the default temperature Value.Certainly, user can change, reset the concrete numerical value of the indoor design temperature Ts according to self-demand.If user Set, indoor design temperature Ts numerical value then refers to the setting numerical value of user.
Step 103:Judge whether outdoor real time temperature Tw is more than outdoor temperature threshold value T1.If so, perform step 105;It is no Then, step 104 is performed.
After step 102 gets outdoor real time temperature Tw, the outdoor real time temperature Tw and outdoor temperature threshold value are judged T1 size.Wherein, outdoor temperature threshold value T1 is a default temperature value, and the temperature value can be according to air-conditioning using area, use Family use demand and change.For example, outdoor temperature threshold value T1 is 20 DEG C.Outdoor real time temperature Tw and outdoor temperature threshold value T1 is made Compare, different disposal process is performed according to comparative result, specifically control the different pattern of operation of air conditioner.
Step 104:Operation of air conditioner heating mode is controlled, until meeting waiting condition.
If step 103 judges that outdoor real time temperature Tw is not more than outdoor temperature threshold value T1, show that outdoor temperature is relatively low.This In the case of, if user opens air-conditioning, more it is desirable to air-conditioning heating operation.Therefore, then no matter indoor real time temperature Tn with With the presence or absence of the temperature difference, the size of the temperature difference between indoor design temperature Ts, operation of air conditioner heating mode is directly controlled, to improve air-conditioning The suitability of room temperature.
By step 103 and the handling process of step 104, can avoid because maloperation generates less than indoor real time temperature Tn Indoor design temperature Ts space-times transfer in into refrigeration mode, cold wind blowed into indoor, the problem so that user feels under the weather hair It is raw.
Step 105:If step 103 judges that outdoor real time temperature Tw is more than outdoor temperature threshold value T1, show outdoor temperature It is not too low.Now, indoor design temperature Ts and indoor real time temperature Tn will be combined which kind of pattern of operation of air conditioner determined.Cause This, calculates indoor design temperature Ts and indoor real time temperature Tn temperature difference △ T first.
Step 106:Judge whether temperature difference △ T are more than the first temperature difference threshold △ T1.If so, perform step 104;If it is not, hold Row step 107.
If temperature difference △ T are more than the first temperature difference threshold △ T1, show indoor real time temperature Tn and indoor design temperature Ts it Between the temperature difference it is larger, to improve user's comfortableness, perform step 104, operation of air conditioner heating mode controlled, until meet standby bar Part.
Step 107:Operation of air conditioner refrigeration mode is controlled, until meeting waiting condition.
If temperature difference △ T are not more than the first temperature difference threshold △ T1, show indoor real time temperature Tn and indoor design temperature Ts Between the temperature difference it is smaller, to cause indoor temperature to reach indoor design temperature Ts as early as possible, control operation of air conditioner refrigeration mode, until Meet waiting condition.
Wherein, the first temperature difference threshold △ T1 are preset value, can be on the occasion of, or negative value.To ensure relaxing for user Adaptive, the first temperature difference threshold △ T1 absolute value can not be too big, and preferably its absolute value is more than 0 DEG C and is not more than 10 DEG C.More preferably , to avoid air-conditioning from frequently changing operational mode, the first temperature difference threshold △ T1 absolute value is more than 0.5 DEG C and is not more than 3 DEG C.
At step 104, air-conditioning will run heating mode, until meeting waiting condition;In step 107, air-conditioning will be transported Row refrigeration mode, until meeting waiting condition.Described waiting condition herein, theoretically, refer to indoor real time temperature Tn with Indoor design temperature Ts is equal.And air-conditioning is operationally, influenceed by air-conditioning temperature adjusting performance, it is difficult to accomplish indoor real time temperature Tn Keep definitely equal with indoor design temperature Ts.In this embodiment, waiting condition is defined as follows:
If operation of air conditioner is in a heating mode, waiting condition is:Compressor of air conditioner continuous working period is set not less than first Fix time, and indoor real time temperature Tn is not less than design temperature Ts.
If operation of air conditioner is in cooling mode, waiting condition is:Compressor of air conditioner continuous working period is set not less than first Fix time, and indoor real time temperature Tn is not more than design temperature Ts.
Set the Rule of judgment that compressor of air conditioner continuous working period is not less than the first setting time, it is therefore an objective to avoid in room The interior real time temperature Tn and indoor design temperature Ts temperature difference is little, compressor operating very short time will shut down and damage compressor The problem of.By setting the Rule of judgment, control compressor just stops after can running reasonable time after starting every time.First Setting time is generally setting value when air-conditioning dispatches from the factory.Preferably, the span of the first setting time is 1-5min.More Preferably, the first setting time is 3min.
In this embodiment, air-conditioning enters after automatic operation mode, is not directly to utilize indoor design temperature Ts and room The interior real time temperature Tn temperature difference enters refrigeration or heating mode, but first obtains outdoor real time temperature as benchmark, control air-conditioning Tw, first judgement is made according to the outdoor real time temperature Tw and outdoor temperature threshold value T1 of setting magnitude relationship, then determined again The temperature difference using indoor design temperature Ts and indoor real time temperature Tn is whether needed to make judgment standard.By by outdoor real time temperature As the Rule of judgment of air conditioning operating mode, can avoid making because indoor design temperature maloperation produces inappropriate temperature value Into control model mistake, so as to avoid control model mistake and cause air-conditioning comfort to reduce, intelligent level declines The problem of.
Fig. 2 is referred to, the figure shows the flow chart of second embodiment of operation of air conditioner control method of the present invention.It is specific next Say, the embodiment refers to air-conditioning from the carrying out practically that standy operation mode is transferred to normal mode of operation, implementation pattern state switches Control flow.
As shown in Fig. 2 the operation control process of second embodiment is specific as follows:
Step 201:Air-conditioning enters standy operation mode.
As described by Fig. 1 one embodiment, after air-conditioning meets waiting condition, standy operation mode will be entered.
Specifically, if air-conditioning enters standy operation mode from the heating mode of step 104, in standy operation mode Under, control indoor fan, outdoor fan and compressor are stopped, reach the purpose of energy-conservation.And if air-conditioning is from step Rapid 107 refrigeration mode enters standy operation mode, then under standy operation mode, controls outdoor fan and the compressor equal It is stopped, and controls indoor fan still to work, to promote air flow using indoor fan, strengthens indoor refrigeration.
Step 202:Operation of air conditioner standy operation mode.
As described above, air-conditioning performs corresponding standby work according into the refrigeration or heating mode before standy operation mode Operation mode process.
Step 203:Judge whether to meet state switching condition.If satisfied, perform step 204;If not satisfied, go to step 202。
Over time, indoor real time temperature Tn can constantly change, and be gradually deviated from indoor design temperature Ts.Cause This, air-conditioner standby mode of operation can not be continued for, and operational mode is then re-introduced into when meeting state switching condition.Here Described state switching condition, refer to the condition that operational mode is re-introduced into from standby mode.In this embodiment, use is standby Determinating reference of the duration of mode of operation as state switching condition.Specifically, state switching condition is in for air-conditioning The duration of standy operation mode is not less than the second setting time.Wherein, when the second setting time is typically also dispatched from the factory for air-conditioning A setting value.Preferably, the span of the second setting time is 8-20min.It is furthermore preferred that the second setting time is 15min。
If state switching condition is unsatisfactory for, namely air-conditioning is in the duration of standy operation mode less than the second setting Time, then air-conditioning remain running under standy operation mode.
Step 204:, will be according to outdoor real time temperature Tw, indoor real time temperature Tn and room if meeting state switching condition Interior design temperature Ts is judged, so which kind of pattern of operation of air conditioner determined.First, obtain outdoor real time temperature Tw and interior is real-time Temperature Tn.
Indoor design temperature Ts is got before entering standy operation mode due to air-conditioning, it is therefore not necessary to obtain again Take.And because outdoor real time temperature Tw and indoor real time temperature Tn are continually changing, therefore, it is necessary to reacquire.Acquisition side Method may be referred to the description of Fig. 1 embodiment steps 102.
Be transferred to by standy operation mode refrigeration or heating mode of operation when, it is necessary to be combined into standy operation mode before Operational mode.Below by according to the handoff procedure for describing state respectively into the different operational modes before standy operation mode.
Step 205:It is refrigeration mode into the operational mode before standy operation mode, step 206 will be performed to step 209 Process.
If former operational mode is refrigeration mode, and from Fig. 1 embodiments, the condition into refrigeration mode is outdoor real-time Temperature Tw is more than outdoor temperature threshold value T1.It is comfortable for indoor temperature to be reached to indoor design temperature Ts, raising room temperature as early as possible Property, then no longer outdoor real time temperature Tw is judged, but directly according to indoor design temperature Ts and indoor real time temperature Tn Carry out the judgement of operational mode.
Step 206:Calculate indoor design temperature Ts and indoor real time temperature Tn temperature difference △ T.
Step 207:Judge whether temperature difference △ T are more than the second temperature difference threshold △ T2.If so, perform step 109;If it is not, hold Row step 108.
Wherein, similar with the first temperature difference threshold △ T1 in Fig. 1 embodiments, the second temperature difference threshold △ T2 are also default Value, can be on the occasion of, or negative value.Moreover, to ensure the comfortableness of user, the second temperature difference threshold △ T2 absolute value is not Can be too big, preferably its absolute value is more than 0 DEG C and is not more than 10 DEG C.It is furthermore preferred that to avoid air-conditioning from frequently changing operational mode, the Two temperature difference threshold △ T2 absolute value is more than 0.5 DEG C and is not more than 3 DEG C.
Step 208:Operation of air conditioner refrigeration mode is controlled, until meeting waiting condition.
If temperature difference △ T are not more than the second temperature difference threshold △ T2, show indoor real time temperature Tn and indoor design temperature Ts Between the temperature difference it is smaller, to cause indoor temperature to reach indoor design temperature Ts as early as possible, control operation of air conditioner refrigeration mode, until Meet waiting condition.
Moreover, after waiting condition is met, step 201 is gone to, air-conditioning is again introduced into standy operation mode.
Step 209:Operation of air conditioner heating mode is controlled, until meeting waiting condition.
If temperature difference △ T are more than the second temperature difference threshold △ T2, show indoor real time temperature Tn and indoor design temperature Ts it Between the temperature difference it is larger, to improve user's comfortableness, operation of air conditioner heating mode is controlled, until meet waiting condition.
Likewise, after waiting condition is met, step 201 is gone to, air-conditioning is again introduced into standy operation mode.
Step 210:If being heating mode into the operational mode before standy operation mode, step 211 will be performed to step 213 and the process of step 208 and step 209.
If former operational mode is heating mode, from Fig. 1 embodiments, two kinds of situations be present into heating mode, first Kind situation is that outdoor real time temperature Tw is not more than outdoor temperature threshold value T1, and second of situation is that outdoor real time temperature Tw is more than outdoor Temperature threshold T1 and indoor design temperature Ts and indoor real time temperature Tn temperature are more than a temperature difference threshold.Therefore, in state , it is necessary to consider outdoor real time temperature Tw influence during switching.
Step 211:Judge whether outdoor real time temperature Tw is more than outdoor temperature threshold value T1.If so, perform step 212;It is no Then, step 209 is performed.
If outdoor real time temperature Tw is not more than outdoor temperature threshold value T1, show that outdoor temperature is relatively low, user wishes to raise Indoor temperature.Therefore, to ensure the suitability of room temperature, step 209 is performed, control air-conditioning directly runs heating mode, directly To meeting waiting condition.
Step 212:If step 211 judges that outdoor real time temperature Tw is more than outdoor temperature threshold value T1, show outdoor temperature It is not too low.Now, which kind of pattern of operation of air conditioner will be determined further in conjunction with indoor design temperature Ts and indoor real time temperature Tn. Therefore, indoor design temperature Ts and indoor real time temperature Tn temperature difference △ T are calculated first.
Step 213:Judge whether temperature difference △ T are more than the 3rd temperature difference threshold △ T3.If so, perform step 209;If it is not, hold Row step 208.
Wherein, the 3rd temperature difference threshold △ T3 are similar with the first temperature difference threshold △ T1 and the second temperature difference threshold △ T2, Ye Shiyi Individual preset value, its span refer to △ T1 or △ T2, not repeated herein.
Moreover, for same air-conditioning, the first temperature difference threshold △ T1, the second temperature difference threshold △ T2 and the 3rd temperature difference threshold △ T3 can select identical numerical value.It is of course also possible to be numerical value that is incomplete same or differing completely, can be according to actual feelings Condition is set.
If temperature difference △ T are more than the 3rd temperature difference threshold △ T3, show indoor real time temperature Tn and indoor design temperature Ts it Between the temperature difference it is larger, to improve user's comfortableness, perform step 209, operation of air conditioner heating mode controlled, until meet standby bar Part.
And if temperature difference △ T are not more than the 3rd temperature difference threshold △ T3, show indoor real time temperature Tn and indoor design temperature The temperature difference between Ts is smaller, to cause indoor temperature to reach indoor design temperature Ts as early as possible, performs step 208, control air-conditioning fortune Row refrigeration mode, until meeting waiting condition.
