Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Core concept of the present invention is: by detecting outdoor environment temperature T4 and indoor environment temperature T1 in real time, the feature of the temperature that then fully conforms according to human body skin, staged cooling method is adopted to control the operation of air-conditioner, and when the indoor objects temperature Ts of user's setting is in the reasonable temperature range of indoor and outdoor surroundings temperature, control the indoor objects temperature Ts that air-conditioner ladder is cooled to user's setting; When the reasonable temperature range of indoor objects temperature lower than indoor and outdoor surroundings temperature of user's setting, control air-conditioner ladder and be cooled to constant operation after the maximum permission temperature difference.Therefore the present invention not only runs staged cooling by controlling air-conditioner, and the present invention also control room internal object temperature operate in the reasonable temperature range of indoor and outdoor surroundings temperature, thus prevent user to pass in and out room causes uncomfortable should with the air conditioner disease caused of lowering the temperature rapidly in room.
As shown in Figure 1, temperature self-adaptation control method first embodiment in a kind of air conditioner chamber of the present invention is shown.In air conditioner chamber in this embodiment, temperature self-adaptation control method comprises the following steps:
Step S10, acquisition outdoor environment temperature T4 and indoor environment temperature T1;
Detect outdoor environment temperature T4 and indoor environment temperature T1 to be detected by the temperature sensor correspondence of the temperature sensor and indoor set that are arranged on air-conditioner outdoor unit.In addition, due in the operation control of air-conditioner, outdoor environment temperature T4 and indoor environment temperature T1 will inevitably detect, and therefore also directly can obtain outdoor environment temperature T4 and indoor environment temperature T1 from the controling parameters of air-conditioner.
Step S11, be less than the first temperature threshold Ta as outdoor environment temperature T4, and the indoor temperature Ts of user's setting is when being less than indoor environment temperature T1, control air-conditioner and run staged cooling mode, until indoor objects temperature equal user setting indoor temperature Ts and outdoor environment temperature T4-X in the higher person, wherein X is the indoor and outdoor surroundings temperature-difference pre-set;
In the present embodiment, by preset first temperature threshold value Ta, preset the reasonable temperature difference X of indoor environment temperature.The span of this first temperature threshold Ta is 35 DEG C ~ 42 DEG C, is preferably 40 DEG C.The span of the reasonable temperature difference X of this indoor environment temperature is 4 DEG C ~ 12 DEG C, is preferably 10 DEG C.User, when startup air-conditioner, by setting the indoor target temperature Ts that will reach, if user is not arranged, is then design temperature during design temperature or the last time shutdown of acquiescence.When this design temperature Ts is less than current indoor environment temperature T1, then start cooling mode, and run staged cooling.To ensure that indoor and outdoor surroundings temperature-difference is in reasonable temperature range, then, after carrying out staged cooling, indoor final target temperature should be more than or equal to T4-X.Therefore, as the design temperature Ts < (T4-X) of user, then carry out staged cooling according to (T4-X), namely control the cooling of air-conditioner staged, until indoor final target temperature equals T4-X; As the design temperature Ts > (T4-X) of user, then carry out staged cooling according to design temperature Ts, namely control the cooling of air-conditioner staged, until indoor final target temperature equals design temperature Ts; As design temperature Ts=(T4-X) of user, then carry out staged cooling according to design temperature Ts or (T4-X).
Step S12, be less than the first temperature threshold Ta as outdoor environment temperature T4, and when the indoor temperature Ts of user's setting is more than or equal to indoor environment temperature T1, controls air-conditioner and run automatic ventilating pattern.
When outdoor environment temperature T4 is less than the first temperature threshold Ta, and the indoor temperature Ts of user's setting is when being more than or equal to indoor environment temperature T1, represent that current indoor temperature is lower than design temperature Ts, then do not need to control air-conditioner and lower the temperature, namely control air-conditioner and run automatic ventilating pattern.
The present invention is by detecting outdoor environment temperature T4 and indoor environment temperature T1 in real time, control air-conditioner when needs are lowered the temperature and run staged cooling mode, and in cooling control procedure, the present invention also control room internal object temperature operates in the reasonable temperature range of indoor and outdoor surroundings temperature, thus prevent user to pass in and out room causes uncomfortable should with the air conditioner disease caused of lowering the temperature rapidly in room.
Further, as shown in Figure 2, temperature self-adaptation control method second embodiment in a kind of air conditioner chamber of the present invention is shown.In the air conditioner chamber of this embodiment in temperature self-adaptation control method, also can comprise after above-mentioned steps S10:
Step S21, be more than or equal to the first temperature threshold Ta as outdoor environment temperature T4, and indoor environment temperature T1 is when being more than or equal to the second temperature threshold Tb, control air-conditioner and run staged cooling mode, until indoor objects temperature equals the higher person in the indoor temperature Ts of user's setting and the second temperature threshold Tb; Wherein, described second temperature threshold Tb is less than the first temperature threshold Ta;
In the present embodiment, also by preset second temperature threshold value Tb, this second temperature threshold Tb is air-conditioner setting when dispatching from the factory, and cannot run to very low temperature for controlling air-conditioner, both the energy had been saved, the infringement will air-conditioner caused when also prevent air-conditioner longtime running low temperature.The span of this second temperature threshold Tb is 25 DEG C ~ 29 DEG C, is preferably 27 DEG C.When outdoor environment temperature T4 is more than or equal to the first temperature threshold Ta, and when indoor environment temperature T1 is more than or equal to the second temperature threshold Tb, represent and need to lower the temperature to air-conditioner, then control air-conditioner and carry out staged cooling.To ensure that air-conditioner cannot run to very low temperature, in staged temperature-fall period, after carrying out staged cooling, indoor final target temperature should be more than or equal to the second temperature threshold Tb.Therefore, as the design temperature Ts < second temperature threshold Tb of user, then carry out staged cooling according to the second temperature threshold Tb, namely control the cooling of air-conditioner staged, until indoor final target temperature equals the second temperature threshold Tb; As the design temperature Ts > second temperature threshold Tb of user, then carry out staged cooling according to design temperature Ts, namely control the cooling of air-conditioner staged, until indoor final target temperature equals design temperature Ts; As the design temperature Ts=second temperature threshold Tb of user, then carry out staged cooling according to design temperature Ts or the second temperature threshold Tb.
Step S22, be more than or equal to the first temperature threshold Ta as outdoor environment temperature T4, and when indoor environment temperature T1 is less than the second temperature threshold Tb, controls air-conditioner and run automatic ventilating pattern.
When outdoor environment temperature T4 is less than the first temperature threshold Ta, and indoor environment temperature T1 is when being less than the second temperature threshold Tb, represent that current indoor temperature is lower than the second temperature threshold Tb, then do not need to control air-conditioner and lower the temperature, namely control air-conditioner and run automatic ventilating pattern.
The embodiment of the present invention, by setting second temperature threshold Tb, makes, in staged cooling controls, can control air-conditioner and cannot run to very low temperature, both save the energy, the infringement will caused air-conditioner when also prevent air-conditioner longtime running low temperature.
Further, as shown in Figure 3, show in air conditioner chamber of the present invention in temperature self-adaptation control method, control the refinement flow process that air-conditioner runs staged cooling mode.In above-mentioned first embodiment and the second embodiment, staged cooling controls control procedure and can comprise the steps:
Step S31, judge whether indoor environment temperature T1 is more than or equal to the 3rd temperature threshold Tc;
Step S32, when indoor environment temperature T1 is more than or equal to the 3rd temperature threshold Tc, control air-conditioner from described 3rd temperature threshold Tc, carry out staged cooling;
Step S33, when indoor environment temperature T1 is less than the 3rd temperature threshold Tc, control air-conditioner indoor environment temperature T1 start to carry out staged cooling;
In the embodiment of the present invention, pre-set the 3rd temperature threshold Tc.The span of the 3rd temperature threshold Tc is 30 DEG C ~ 32 DEG C, is preferably 30 DEG C.Compared by this indoor environment temperature T1 and the 3rd temperature threshold Tc, to determine the initial temperature that staged is lowered the temperature.Such as, when indoor environment temperature T1 is more than or equal to the 3rd temperature threshold Tc, controls air-conditioner and carry out staged cooling from described 3rd temperature threshold Tc; When indoor environment temperature T1 is less than the 3rd temperature threshold Tc, control air-conditioner indoor environment temperature T1 starts to carry out staged cooling.Based on the first embodiment, after staged cooling, indoor final target temperature equals the higher person in the indoor temperature Ts of user's setting and the second temperature threshold Tb; Based on the second embodiment, after staged cooling, indoor final target temperature equals the higher person in the indoor temperature Ts of user's setting and outdoor environment temperature T4-X.
The embodiment of the present invention is by arranging the 3rd temperature threshold Tc, the initial temperature in staged temperature-fall period can be controlled, thus make when indoor environment temperature T1 is more than or equal to the 3rd temperature threshold Tc, directly start to carry out staged cooling with the 3rd temperature threshold Tc, start to carry out staged cooling relative to indoor environment temperature T1, greatly reduce temperature fall time.
Further, the concrete control procedure of above-mentioned staged cooling is: from temperature when carrying out staged cooling after continuous working period t1, the current indoor target temperature controlling air-conditioner declines the 4th temperature threshold Td the time t2 that reruns, by that analogy, until staged cooling terminates.The span of this time t1 and time t2 is 3 minutes ~ 20 minutes, and each time continued can be equal, also can extend gradually.As shown in Figure 4, when starting to carry out staged cooling, Current Temperatures is greater than 30 DEG C, then the current design temperature of air-conditioner is set to 30 DEG C, and after controlling the air-conditioner continuous service t1 time with this current design temperature, the current design temperature of air-conditioner is reduced to 28 DEG C, and control the air-conditioner continuous service t2 time with this current design temperature, the rest may be inferred, until indoor temperature equals T4-X, then controls air-conditioner continuous service.The present invention is by constantly changing the indoor objects temperature of air-conditioner and duration when reaching this target temperature, to reach the object of slow cooling, thus avoid the problem that fast cooling easily causes the air conditioner diseases such as flu, particularly for more weak old man, child, the women of health, for the more sensitive user of variation of ambient temperature, control model of the present invention effectively can prevent the generation of air conditioner disease.Meanwhile, due to ladder cooling, compressor will be in low-frequency operation always, and wind speed is also in low cruise always, therefore while guarantee health and comfortableness, also achieve power and energy saving and will run.
The indoor temperature adaptive control process of air-conditioner of the present invention will be set forth below with a concrete example.In this example, the first temperature threshold Ta=40 DEG C, the second temperature threshold Tb=27 DEG C, the 3rd temperature threshold Tc=30 DEG C, indoor and outdoor surroundings temperature-difference X=10 DEG C.During ladder cooling controls, t1 is 15 minutes, and t2 is 18 minutes, and t3 is 21 minutes, by that analogy; 4th temperature threshold Td=2 DEG C.Concrete control procedure is as follows:

S109, due to T4=35 DEG C of < Ta=40 DEG C, therefore, indoor environment temperature T1 when detecting start, and judge whether Ts is greater than T1; As Ts < T1, perform S110, otherwise perform S113;
S110, as T1=32 DEG C, due to Ts=20 DEG C of < T1=32 DEG C, therefore, judge T1 whether be greater than the 3rd temperature threshold Tc=30 DEG C, as T1 >=Tc, perform S111, otherwise perform S112;
S111, due to T1=32 DEG C >=Tc=30 DEG C time, therefore, control air-conditioner ladder from the 3rd temperature threshold Tc=30 DEG C s and be cooled to T4-X=35-10=25 DEG C (herein selection Ts=20 and T4-X=35-10=25 DEG C of the higher person);
S112, as T1=28 DEG C, due to T1=28 DEG C of < Tc=30 DEG C, therefore, control air-conditioner ladder from current indoor environment temperature T1=28 DEG C to be cooled to T4-X=35-10=25 DEG C (selecting Ts=20 and T4-X=35-10=25 DEG C of the higher person herein);
S113, as T1=18 DEG C, due to Ts=20 DEG C >=T1=18 DEG C, therefore, control air-conditioner and run automatic ventilating pattern;
Wherein, ladder cooling in above-mentioned steps S111 refers to continuous working period t1=15 minute from the 3rd temperature threshold Tc=30 DEG C, then design temperature is reduced to the 30-Tc=30-2=28 DEG C of t2=18 minute that reruns, by that analogy, until move to Ts or T4-X (selecting Ts and T4-X the higher person herein);
Ladder cooling in above-mentioned steps S112 refers to continuous working period t1=15 minute from current indoor environment temperature T1, then reduce design temperature to rerun t2=18 minute to T1-Tc=28 DEG C-2=26 DEG C, by that analogy, until move to Ts or T4-X (selecting Ts and T4-X the higher person herein).
