In the embodiment of the disclosure, when the air conditioner is in refrigeration operation, the indoor fan of the air conditioner can be in intermittent sleep operation according to refrigeration requirements, namely, the indoor fan is in an intelligent energy-saving mode, so that not only is the state of the indoor fan automatically controlled according to an application scene realized, the intelligence of the air conditioner is improved, but also unnecessary power consumption of the fan is reduced, energy resources are saved, meanwhile, heating of the fan is avoided, and the service life of the fan is prolonged.
Fig. 1 is a schematic flow chart of a control method for an indoor fan of an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, the process of the air conditioning control includes:
step 101: and under the condition that an indoor fan of the air conditioner is in an operating state, acquiring a current temperature rise value in an air conditioner acting area.
When the air conditioner operates in the refrigeration mode, the indoor fan can operate according to a user instruction or a strategy matched with the refrigeration mode, namely, the indoor fan is in an operating state, and at the moment, the current temperature rise value corresponding to the current moment in the air conditioning action area can be obtained.
In some embodiments, obtaining the current temperature rise value in the air conditioning active region comprises: acquiring a current temperature value in an air conditioning action area at the current moment; and obtaining a current temperature difference value between the current temperature value and the initial temperature value, and determining the current temperature difference value as a current temperature rise value, wherein the initial temperature value is a temperature value in an air conditioning action area corresponding to the starting point moment of the first period of time.
The first period of time may be 2min, 3min, 5min, or 6min, etc., and thus, one time may be determined as a starting time of the first period of time, i.e., starting from the starting time, a corresponding timer is started. In addition, during the operation process of the air conditioner, the indoor environment temperature of the air conditioning action area, for example, the indoor environment temperature, may be collected in real time or at regular time, the indoor environment temperature corresponding to the starting point of the first period of time is the starting temperature value Tq, and the current temperature value collected at the current time is the current temperature value Td in the air conditioning action area, so that the current temperature difference between the current temperature value and the starting temperature value may be obtained, and thus, the current temperature difference may be determined as the current temperature rise value Δ T, that is, Δ T ═ Td-Tq.
Step 102: and under the condition that the duration time of the current temperature rise value which is less than the set temperature value reaches the first period of time, acquiring the current refrigeration demand of the air conditioner.
Starting from the starting moment of the first period of time, acquiring the indoor environment temperature once, and obtaining the current temperature rise value once, wherein the current temperature values may be different due to different acquired time points, so that the corresponding current temperature rise values are not different.
The set temperature value may be a fixed value, for example: 0.5 deg.C, 0.8 deg.C, 1 deg.C, or 1.5 deg.C, etc. Since the corresponding collection time points are different and the corresponding current temperature rise values are also not different, in some embodiments, the set temperature value may be a variable related to the sampling time, that is, the set temperature value a ═ is (current time td — start time tq) × (b), where b may be a preset value.
The temperature accuracy J of the air-conditioning temperature adjustment is configured, and in the smart energy saving mode of the air-conditioning indoor fan, the second period of time t2 corresponding to the indoor fan stopped state, so that it is possible to determine that b is J/t2, and thus, it is possible to determine that the set temperature value a is (td-tq) × (J/t 2). Namely, the set temperature value is (current time-starting time) × (preset temperature accuracy/second period of time).
For example: the temperature accuracy J is 3 ℃, t2 is 4min, and the time duration (td-tq) corresponding to the current time is 2min, so that the set temperature value a is (2 × 3)/4 is 1.5 ℃. Therefore, if the current temperature rise value delta T is less than 1.5 ℃, the duration that the current temperature rise value is less than the set temperature value can be continuously timed. Of course, b may be other preset values.
In some embodiments, when the current temperature rise value is greater than or equal to the set temperature value, the duration is cleared, the current time is determined as the starting time of the first period of time, and the current temperature value in the air-conditioning action area at the current time is determined as the starting temperature value of the first period of time.
When the current temperature rise value is greater than or equal to the set temperature value, the timed duration time that the current temperature rise value is smaller than the set temperature value needs to be cleared immediately, the current time is determined as the starting time of the first period of time, and the current temperature value in the air-conditioning action area at the current time is determined as the starting temperature value of the first period of time. I.e. a new first period of time has started.
For example: when the current temperature rise value delta T is less than the set temperature value 1.6 ℃, the duration that the current temperature rise value is less than the set temperature value can be continuously timed; when the current temperature rise value delta T is larger than or equal to the set temperature value 1.6 ℃, the duration time needs to be cleared, Td is determined as Tq, Td is determined as Tq, a new timer is started to time, when the current temperature rise value delta T obtained by next sampling is smaller than the set temperature value 1.6 ℃, the accumulated time of the duration time can be continuously timed, once the duration time does not reach the first period of time and the current temperature rise value delta T obtained by sampling is larger than or equal to the set temperature value 1.6 ℃, the accumulated duration time needs to be cleared, Td needs to be determined as Tq, and Td is determined as Tq.
The intelligent demand of the air conditioner is related to a current temperature value Td of the air conditioner, a target temperature value Tm, and a temperature precision J of air conditioner temperature regulation, and in some embodiments, the current cooling demand is (current temperature value-target temperature value)/preset temperature precision.
Step 103: under the condition that present refrigeration demand is less than the settlement demand, the indoor fan of control air conditioner carries out the operation of intelligent energy-conserving mode, wherein, intelligent energy-conserving mode includes: the stop state and the running state are alternated, the stop state corresponds to the second period of time, and the running state corresponds to the third period of time.
The set demand may be determined according to the performance of the air conditioner, the geographical area where the air conditioner is located, and the like, for example: the set demand may be 50%, 55%, 60%, 65%, 70%, etc. Therefore, when the current refrigerating demand Qd is less than 65%, the air conditioner can be determined to be in a low demand state, so that the indoor fan of the air conditioner can be controlled to operate in an intelligent energy-saving mode, the indoor fan of the air conditioner in the intelligent energy-saving mode is in an intermittent dormant mode, the shutdown state of the indoor fan corresponds to the second period of time, and the operating state of the indoor fan corresponds to the third period of time.
For example: when the indoor fan operates in the intelligent energy-saving mode, the indoor fan stops operating for 5min, then starts operating for 3min, namely the second period of time is 5min, and the third period of time is 3 min. Therefore, the indoor fans operate alternately, unnecessary power consumption of the fans can be reduced, resources are saved, heating of the fans is avoided, and the service life of the fans is prolonged.
Of course, in some embodiments, in the case that the current temperature rise value is greater than or equal to the set temperature value, the duration is cleared, the current time is determined as the starting time of the first period of time, and the current temperature value in the air-conditioning action area at the current time is determined as the starting temperature value of the first period of time.
At the moment, the indoor fan cannot be operated in an intelligent energy-saving mode, timing needs to be restarted, namely, the duration time needs to be cleared, Td needs to be determined as Tq, and Td is determined as Tq.
Therefore, in the embodiment of the disclosure, when the air conditioner operates in a cooling mode, in a period of time, the temperature rise value, that is, the temperature rise value, in the air conditioning action area is always smaller than the set temperature value, and the corresponding cooling demand is also smaller than the set demand, the indoor unit of the air conditioner can be controlled to operate in an intelligent energy-saving mode, that is, the stop state and the operation state are alternately performed, so that the state of the indoor fan can be automatically controlled according to an application scene, the intelligence of the air conditioner is improved, and in addition, when the air conditioner is in a low demand, the indoor fan is intermittently dormant, the meaningless power consumption and the energy-saving resources of the fan are reduced, meanwhile, the heating of the fan is avoided, and the service life of the fan is prolonged.
When the indoor fan of the air conditioner operates in the intelligent energy-saving mode, the indoor fan is started to operate after being in the stop state for the second period of time, and after the indoor fan is in the operating state, the indoor fan of the air conditioner can be triggered to enter the intelligent energy-saving mode to operate according to the current temperature rise value and the current refrigerating demand, the indoor fan of the air conditioner is automatically switched to the stop state from the operating state, and the automatic switching of the operating state and the stop state is realized. And the duration time that the current temperature rise value is less than the set temperature value reaches the first period of time, so that a trigger condition for the indoor fan to operate in the intelligent energy-saving mode can be met, and once the duration time does not meet the requirement of accumulated timing again, the third period of time corresponding to the operation state can be greater than or equal to the first period of time.
Of course, the specific operation parameters corresponding to the operation state of the indoor fan can still be adjusted according to the operation mode of the air conditioner, that is, the operation parameters of the indoor fan are adjusted according to the operation mode of the air conditioner under the condition that the indoor fan of the air conditioner is in the operation state. In other words, in the embodiment, the running time of the indoor fan can be changed according to the application scene, the specific running parameters are not changed, and the normal running of the air conditioner is guaranteed.
The following operation flow is integrated into a specific embodiment to illustrate the control process for the indoor fan of the air conditioner provided by the embodiment of the present invention.
In an embodiment of the present disclosure, the set temperature value a may be a fixed value, which may be 1.5 ℃, and the set demand may also be a fixed value of 60%. The first period of time is 2min, the second period of time is 4min, and the third period of time is 5 min. The preset temperature accuracy may be 2 deg.c and the target temperature value may be 26 deg.c.
Fig. 2 is a schematic flow chart of a control method for an indoor fan of an air conditioner according to an embodiment of the present disclosure. Referring to fig. 2, the control process of the indoor fan of the air conditioner includes:
step 201: under the condition that an indoor fan of the air conditioner is in an operating state, a current temperature value Td in an air conditioner action area at the current moment is obtained, and a current temperature rise value delta T between the current temperature value and an initial temperature value is obtained.
After the air conditioner is started and the refrigeration operation is carried out, any one moment can be determined as the starting moment of the first period of time, and the corresponding temperature value is the starting temperature value.
Step 202: determine whether the current temperature rise Δ T < 1.5? If so, go to step 203, otherwise, go to step 208.

Step 206: determine whether the current refrigeration demand Qd < 60% holds? If yes, go to step 207, otherwise, go to step 208.
Step 207: and controlling the indoor fan to perform an intelligent energy-saving mode.

The target temperature value was 23 ℃. Thus, b is 3/5 is 0.6.

The temperature value a is set to (td-tq) × 0.6. For example: and (td-tq) ═ 1.5, then a equals 0.9. If (td-tq) ═ 3, a is 1.8.

If Δ T is greater than or equal to a, the clear module 440 needs to clear the duration, determine the current time as the starting time of the first period of time, and determine the current temperature value as the starting temperature value of the first period of time.
When the current cooling demand Qd is less than 65%, the first control module 430 may control the indoor fan to be in a stopped state, and control the indoor fan to be in an operating state when the time of the stopped state reaches 5 min. Therefore, the temperature rise obtaining module 410 continues to obtain the current temperature value Td, and continues to judge the triggering condition of the intelligent energy-saving mode of the indoor fan, so that automatic mutual switching between the stop state and the running state of the indoor fan is realized.
If the current refrigeration demand Qd is greater than or equal to 65%, the zero clearing module 440 also needs to clear the duration, determine the current time as the starting time of the first period, and determine the current temperature value as the starting temperature value of the first period.
Of course, in the case that the indoor fan of the air conditioner is in an operating state, the second control module 450 adjusts an operating parameter of the indoor fan according to an operating mode of the air conditioner.
Therefore, in the embodiment, when the air conditioner operates in a refrigerating mode, the device for controlling the indoor fan of the air conditioner can realize automatic mutual switching between the stop state and the operating state of the indoor fan according to the refrigerating requirement, so that the intelligence of the air conditioner is improved, the unnecessary power consumption of the fan is reduced, the resources are saved, meanwhile, the heating of the fan is avoided, and the service life of the fan is prolonged.
