Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to facilitate understanding of the present embodiment, a detailed description is first provided below of a method for controlling fresh air of an air conditioner according to an embodiment of the present invention. The execution main body is a controller of the fresh air conditioner, in addition, the fresh air conditioner comprises a fresh air fan and an indoor circulating fan which are in communication connection with the controller, an air conditioner remote controller or remote control equipment and the like, a user can control the starting and stopping of the fresh air conditioner through the air conditioner remote controller, and an operation mode and the like are set, wherein the operation mode comprises, but is not limited to, a heating mode, a refrigerating mode, a dehumidifying mode and the like, and the structure of the fresh air conditioner can be set according to actual conditions.
Based on the above fresh air conditioner, the embodiment of the invention provides a fresh air control method of an air conditioner, as shown in fig. 1, the method comprises the following steps:
step S102, when the fresh air fan and the indoor circulating fan are monitored to be started simultaneously, the rotating speed of the indoor circulating fan is obtained;
specifically, when the user starts the fresh air conditioner to operate through the air conditioner remote controller and starts the fresh air mode and the heating mode (or the refrigerating mode), at this time, the fresh air fan of the fresh air conditioner and the indoor circulating fan are simultaneously started to operate, and the controller acquires the rotation speed of the indoor circulating fan, for example, the rotation speed of the indoor circulating fan is detected through the detecting unit, and the detecting unit includes, but is not limited to, a speed sensor and the like, and can be specifically set according to practical situations.
Step S104, determining the target rotating speed of the fresh air fan according to the rotating speed of the indoor circulating fan and a preset ratio A;
specifically, the target rotational speed of the fresh air fan may be calculated according to the following formula: n is n Target object ＝n 1 * A, A is as follows; wherein n is Target object Indicating the target rotating speed of the fresh air fan, n 1 The rotating speed of the indoor circulating fan is represented, and the preset ratio A meets the following conditions: 1.1 is less than or equal to A is less than or equal to 1.25, so that on the basis of ensuring fresh air quantity, the target rotating speed of the fresh air fan is adjusted through the rotating speed of the indoor circulating fan, thereby not only avoiding the resonance of two fans, but also avoiding the mixed noise of the two fans to exceed 3% of the noise of the single-opening indoor circulating fan, and relieving the problems of high resonance and noise and the like generated by the indoor circulating fan and the fresh air fan.
Furthermore, for a preset ratio a, the method further comprises: and determining a preset ratio A according to the rotating speed of the indoor circulating fan and a preset rotating speed threshold value. The preset rotating speed threshold comprises a preset first rotating speed threshold and a preset second rotating speed threshold, and the preset second rotating speed threshold is larger than the preset first rotating speed threshold; specifically, if the rotational speed of the indoor circulation fan is smaller than the preset first rotational speed threshold value, the preset ratio a satisfies: a is more than 1.17 and less than or equal to 1.25; or if the rotating speed of the indoor circulating fan is greater than the preset second rotating speed threshold value, the preset ratio A meets the following conditions: a is more than 1.17 and less than or equal to 1.25.
For example, as shown in fig. 2, according to the curve of the ratio a, a preset first rotation speed threshold value of 650r/min and a preset second rotation speed threshold value of 920r/min can be calculated, when the rotation speed of the indoor circulating fan is less than 650r/min, a is more than 1.17 and less than or equal to 1.25, so that the rotation speed difference value of the indoor circulating fan and the fresh air fan under low-rotation-speed operation is ensured, and low-speed resonance is avoided; when the rotating speed of the indoor circulating fan is greater than 920r/min, A is more than 1.17 and less than or equal to 1.25, so that the fresh air quantity is improved under the condition of meeting noise and resonance. For the rotation speeds of the indoor circulating fans with low wind level, medium wind level and high wind level, according to different preset ratios A, the corresponding target rotation speeds of the fresh air fans can be calculated, as shown in the following table 1:
TABLE 1
In sum, according to the rotating speeds of different indoor circulating fans and the preset ratio A, different target rotating speeds of the fresh air fan can be determined, so that different fresh air volumes are controlled, the fresh air volume is ensured, and the room comfort is improved; meanwhile, the resonance and noise problems generated by the fresh air fan and the indoor circulating fan are relieved, and the experience of a user is improved.
And S106, controlling the fresh air fan to operate according to the target rotating speed.
According to the fresh air control method for the air conditioner, the rotating speed of the fresh air fan is adjusted according to the rotating speed of the indoor circulating fan, so that the fresh air quantity is ensured, and the room comfort is improved; and the resonance and noise problems generated by the fresh air fan and the indoor circulating fan are also relieved, and the air conditioner has good practical value.
Further, the method comprises the following steps: acquiring the current running mode and the outdoor environment temperature of a fresh air conditioner; and determining the target rotating speed of the fresh air fan according to the outdoor environment temperature and the preset temperature threshold. On the basis of alleviating resonance and noise according to the relation between the indoor circulating fan and the fresh air fan, the fresh air volume is further controlled according to the outdoor environment temperature and a preset temperature threshold value, so that the influence of the fresh air volume on the comfort of a room is reduced, and the comfort of the room is improved.
For ease of understanding, the current operating mode is divided here into two types: one is a fresh air mode and a cooling mode, and the other is a fresh air mode and a heating mode, and the two current operation modes are described in detail below.

step S304, judging T Outer ring Not less than 43 ℃; i.e. judging the outdoor environment temperature T Outer ring Whether the temperature is not smaller than a preset first temperature threshold value; if yes, step S306 is executed, and if no, step S308 is executed;
step S306, determining that the target rotating speed of the fresh air speed is a low wind gear; the controller forcedly controls the fresh air speed to run according to the low wind gear;
step S308, determining the target rotating speed of the fresh air fan according to the rotating speed of the indoor circulating fan and a preset ratio A;
and step S310, controlling the fresh air fan to operate according to the target rotating speed.
Therefore, when the fresh air mode and the refrigeration mode are simultaneously operated, the outdoor environment temperature T Outer ring When the temperature is not smaller than the preset first temperature threshold, the controller controls the fresh air fan to operate according to the low wind level so as to reduce the fresh air quantity, and when the outdoor environment temperature T is lower than the preset first temperature threshold Outer ring When the temperature of the air conditioner is smaller than a preset first temperature threshold value, the rotating speed of the fresh air fan is adjusted according to the rotating speed of the indoor circulating fan, so that the fresh air quantity is ensured, and the room comfort is improved; and the resonance and noise problems generated by the fresh air fan and the indoor circulating fan are also relieved, and the air conditioner has good practical value.
Similarly, as shown in fig. 4, if the current operation mode is a fresh air mode and a heating mode, the preset temperature threshold includes a preset second temperature threshold, where the preset second temperature threshold is-5 ℃; the method specifically comprises the following steps:
step S402, a fresh air mode and a heating mode are started; when a user starts a fresh air conditioner to operate through an air conditioner remote controller and starts a fresh air mode and a heating mode, at the moment, a fresh air fan and an indoor circulating fan of the fresh air conditioner are simultaneously started to operate;
step S404, judging T Outer ring The temperature is less than or equal to-5 ℃; i.e. judging the outdoor environment temperature T Outer ring Whether the temperature is not greater than a preset second temperature threshold; if yes, step S406 is performed, and if no, step S408 is performed;
step S406, determining that the target rotating speed of the fresh air speed is a low wind gear; the controller forcedly controls the fresh air speed to run according to the low wind gear;
step S408, determining the target rotating speed of the fresh air fan according to the rotating speed of the indoor circulating fan and a preset ratio A;
step S410, the fresh air fan is controlled to operate according to the target rotating speed.
Therefore, when the fresh air mode and the heating mode are simultaneously operated, the outdoor environment temperature T Outer ring When the temperature is not greater than the preset second temperature threshold, the controller controls the fresh air fan to operate according to the low wind level so as to reduce the fresh air quantity, and when the outdoor environment temperature T is lower than the preset second temperature threshold Outer ring When the temperature of the air conditioner is greater than a preset second temperature threshold value, the rotating speed of the fresh air fan is adjusted according to the rotating speed of the indoor circulating fan, so that the fresh air quantity is ensured, and the room comfort is improved; and the resonance and noise problems generated by the fresh air fan and the indoor circulating fan are also relieved, and the air conditioner has good practical value.
