Detailed Description
The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The embodiment provides a control method for prolonging heating time of an air conditioner, which can be applied to a controller of the air conditioner, and referring to a flow chart of the control method for prolonging heating time of the air conditioner shown in fig. 1, the method mainly comprises the following steps S102 to S106:
step S102: in the process that the air conditioner is in periodic heating operation and defrosting, when the heating operation is finished and the defrosting mode is entered in each period, the defrosting times of the air conditioner are obtained, the heating operation time length of the air conditioner in the current period is obtained, and the first time length is obtained.
When the air conditioner performs defrosting in heating operation, the air conditioner enters a defrosting mode to defrost when a certain heating time is met or the outdoor unit is detected to be frosted thickly, and then exits the defrosting mode to enter the heating mode to operate after entering the defrosting mode to operate for a certain time, so that the cycle is repeated, and the periodic heating operation and defrosting are realized. Counting the defrosting times of the air conditioner, namely the times of the air conditioner entering the defrosting mode to operate, entering the next period after the air conditioner completes the heating operation and the defrosting mode, timing the heating operation time length in each period, acquiring the defrosting times counted in the current period when the air conditioner finishes the heating operation and enters the defrosting mode in each period, and acquiring the heating operation time length in the current period and recording as the first time length.
Step S104: and detecting the outdoor environment humidity when the first time length is less than the preset time length.
And judging whether the heating operation time length of the air conditioner in the current period is less than the preset time length, if the heating operation time length of the air conditioner in the current period is shorter, detecting the humidity of the outdoor unit side based on a humidity sensor, and recording the humidity as the outdoor environment humidity.
Step S106: and when the outdoor environment humidity is greater than the preset humidity threshold value, or when the outdoor environment humidity is less than the preset humidity threshold value and the defrosting times are greater than or equal to the preset times, controlling the air conditioner to perform heating operation for a second time length in the next period, and controlling the external fan to perform operation at a second preset rotating speed in the next period.
The second duration is longer than the first duration, and the second preset rotating speed is greater than the first preset rotating speed of the outer fan in the current period. When the outdoor environment humidity is higher, it indicates that the outdoor side humidity is higher, the outdoor unit frosts faster, and the air conditioner can perform frequent defrosting. Or when the outdoor environment humidity is lower, judging whether the defrosting times of the air conditioner in the current period are more than or equal to the preset times so as to judge whether the frosting rate of the outdoor unit is higher, and when the defrosting times of the air conditioner are more than or equal to the preset times, indicating that the frosting rate of the outdoor unit is higher. When the outdoor unit frosts frequently, the air conditioner is controlled to prolong the heating operation time in the next period, and simultaneously the rotating speed of the outer fan is increased, so that the frosting speed is reduced, the heating time is prolonged, the heating effect is improved, and the rationality of the heating air-out temperature is ensured.
The value range of the preset times can be 2-3 times, and the preferred value is 2. The value range of the preset duration can be 50-80 min, and the preferred value is 60 min. The value range of the preset humidity threshold value can be 45-55%, and the preferred value is 50%.
In a possible embodiment, the difference between the second preset rotation speed and the first preset rotation speed is N × 20r/min, where N is the number of times of defrosting. Namely, when the heating time is prolonged in the next period, the rotating speed of the outer fan is controlled to be increased by N x 20r/min, so that the frosting rate is prevented from being further increased, and the heating effect is ensured.
According to the control method for prolonging the heating time of the air conditioner, when the defrosting frequency of the air conditioner is high, the heating operation time is prolonged, the rotating speed of the outer fan is increased, the frosting rate is reduced, the heating effect is guaranteed, the heating effect is prevented from being influenced by the high frosting rate, and the use experience of a user is improved.
In order to avoid the problem that the outdoor unit frost layer is too thick when the air conditioner heating operation time is long, the control method for prolonging the heating time of the air conditioner provided by the embodiment further comprises the following steps (1) to (2)
Step (1): and when the outer fan operates at a second preset rotating speed in the next period, monitoring the air outlet temperature of the indoor unit and the temperature of the outer coil pipe.
When the air conditioner increases the rotating speed of the outer fan and prolongs the long running process during heating operation, the air outlet temperature of the indoor unit and the temperature of the outer coil pipe are respectively detected in real time based on the temperature sensor.
Step (2): and if the air outlet temperature of the indoor unit is less than or equal to a first preset temperature or the temperature of the outer coil is less than or equal to a second preset temperature, controlling the air conditioner to stop heating operation and enter a defrosting mode for operation.
Judging whether the air outlet temperature of the indoor unit is less than or equal to a first preset temperature, and judging whether the temperature of the outer coil pipe is less than or equal to a second preset temperature, wherein the first preset temperature can be a temperature close to the temperature of a human body, the value range of the first preset temperature can be 36.0-37.8 ℃, and the value range of the second preset temperature can be-5-7 ℃.
If the air outlet temperature of the indoor unit is detected to be low, or the temperature of the outer coil pipe is detected to be low, the air conditioner is controlled to stop heating to enter a defrosting mode, the condition that the air outlet temperature of the indoor unit is low to influence user experience is avoided, and meanwhile, the condition that the defrosting mode is long in operation time due to the fact that the frost layer of the outdoor unit is too thick can be avoided.
In a possible implementation manner, the control method for extending the heating time of the air conditioner provided in this embodiment further includes: and when the defrosting mode of the current period is finished, controlling the defrosting times to be increased by one, controlling the air conditioner to enter the heating operation of the next period, and when the heating operation of the next period is finished, returning to execute the operation of finishing the heating operation in each period and entering the defrosting mode, acquiring the defrosting times of the air conditioner, and acquiring the heating operation time length of the air conditioner in the current period.
And when the defrosting mode of the current period is finished, adding 1 to the counted defrosting times, and when the heating operation of the next period of the air conditioner is finished, returning to execute the step S102, and taking the next period as the current period to judge whether the air conditioner needs to continue to prolong the heating operation time. The frosting rate is judged in each heating operation and defrosting period, so that the heating operation time and the rotating speed of the external fan change along with the frosting rate of the outdoor unit, the indoor heating effect is guaranteed, and the use experience of a user is optimized.
In a possible implementation manner, when considering that the frosting rate of the outdoor unit is low, the control method for extending the heating time of the air conditioner provided in this embodiment further includes: and when the outdoor environment humidity is smaller than the preset humidity threshold value and the defrosting time is smaller than the preset time, or when the first time is longer than the preset time, controlling the air conditioner to heat for the first time in the next period, and controlling the outer fan to operate at the first preset rotating speed in the next period.
When the outdoor environment humidity is low and the defrosting frequency of the current period is low, or the heating operation time length in the current period is long, the frosting rate of the outdoor unit is low, the heating operation time length and the rotating speed of the external fan are not adjusted in the next period, namely the heating operation time length of the next period is controlled to be the same as the heating operation time length of the current period, and the rotating speed of the external fan in the next period is controlled to be the same as the current period. When the frosting rate of the outer fan is low, the rotating speed of the outer fan and the heating operation time of the next period are not adjusted, so that the defrosting effect of the air conditioner is ensured, and the operation stability of the air conditioner is improved.
In a possible embodiment, the second preset rotation speed is less than the upper limit of the rotation speed of the outer fan, and the rotation speed of the outer fan should not exceed the upper limit of the rotation speed of the outer fan of the air conditioner when the rotation speed of the outer fan is controlled to be increased. The rotating speed of the outer fan is not more than the rotating speed upper limit value, the rotating speed of the outer fan is prevented from being too large, and the running reliability of the air conditioner is improved.
In a possible implementation manner, the control method for extending the heating time of the air conditioner provided in this embodiment further includes: when the air conditioner exits the periodic heating operation and defrosting, or when a temperature adjusting instruction or a wind speed adjusting instruction is received, the defrosting times are controlled to be cleared, and long data and external fan rotating speed data during the heating operation are cleared.
When a user adjusts the heating set temperature or the air speed of the indoor unit, the defrosting times are controlled to be reset, adjustment data made on the heating operation time and the rotating speed of the outer fan are clear, the heating operation and the defrosting operation of the air conditioner are restarted, the situation that the rotating speed of the outdoor unit and the heating operation time are not matched with the user requirements due to the change of the user requirements is avoided, and the user experience is improved.
According to the control method for prolonging the heating time of the air conditioner, when the air conditioner is frequently defrosted, the frosting can be slowed down, the heating time is prolonged, the heating effect of the air conditioner is improved, and the use experience of the air conditioner is optimized on the basis of ensuring the reasonable air outlet temperature by prolonging the heating operation time and increasing the rotating speed of the outer fan.

And step 3: if Ts is more than 50%, the humidity of the outdoor unit side is higher, the frosting is faster, and the rotating speed of the outer fan needs to be increased by N x 20r/min during the next heating operation period.

When the user turns down the temperature and the wind speed of the air conditioner remote controller, the adjustment made by the control scheme is reset again, the storage is not carried out, and the control scheme is restarted (the situation that the user runs at a high rotating speed of an outdoor motor due to the reduction of the requirement is avoided). And the rotating speed of the outer motor is increased to set a limit, and the highest rotating speed should not exceed the upper limit of the rotating speed of the outer motor.
