Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
A control method of an air conditioner according to an embodiment of the present invention is described below with reference to fig. 1 to 2.
As shown in fig. 1, a control method of an air conditioner according to an embodiment of the present invention includes the steps of:
when the air conditioner enters a heating mode, the compressor and the indoor fan are controlled to operate, when the compressor operates, the indoor heat exchanger releases heat, and airflow with higher temperature around the indoor heat exchanger can flow out from the air outlet under the driving of the indoor fan;
the air deflector is controlled to be opened to a first air outlet angle so as to enable the air outlet direction to be upward. It should be noted that the air outlet may be disposed on a housing of the air conditioner, and the air deflector may close and open the air outlet, for example, as shown in fig. 3, a position of a straight line of an arrow is a position of a windward side of the air deflector, a direction of the arrow is a direction of an air flow guided by the air deflector, the air deflector is rotatable relative to the housing of the air conditioner, and a starting position of the arrow in fig. 3 may be a position of a rotation axis of the air deflector. As shown in fig. 3, when the air deflector is located at a position for closing the air outlet, the air outlet is shielded by the air deflector; when the air deflector is located at the full-open angle position, the air outlet is completely open. The first air outlet angle is located between the position for closing the air outlet and the position for fully opening the air outlet, and when the air deflector is located at the first air outlet angle, the air deflector can guide the air flow to flow upwards. In some examples, when the air deflector is located at the first air outlet angle, the air deflector extends obliquely upwards along the air outlet direction, so that the air flow blown out from the air outlet can be prevented from directly blowing to the human body;
detecting the temperature of the indoor heat exchanger in real time;
when the temperature IPT of the indoor heat exchanger reaches the set wind speed operation temperature T of the indoor fan, the indoor fan is controlled to operate at the set wind speed, the air deflector is opened to a second air outlet angle, and the second air outlet angle is larger than the first air outlet angle. In some examples, when the air deflector is located at the second air outlet angle, the air deflector is horizontal, so that the air flow can flow out from the air outlet, the uniformity of the indoor environment temperature can be improved, and the use comfort of the air conditioner can be improved.
It should be noted that, in the initial stage after the compressor is started, the compressor has poor heating efficiency, the temperature of the air flow blown out from the air outlet is low, and the air flow with low temperature is blown onto the human face, which will reduce the comfort of the air conditioner.
According to the control method of the air conditioner, when the temperature IPT of the indoor heat exchanger reaches the set wind speed operation temperature T of the indoor fan, the air outlet angle of the air deflector is adjusted to the second air outlet angle, and the second air outlet angle is larger than the first air outlet angle, so that the air deflector can be used for guiding airflow to flow upwards, direct blowing to a user can be avoided, and the comfort of the air conditioner can be improved.
According to some embodiments of the invention, before the temperature IPT of the indoor heat exchanger reaches the set wind speed operation temperature T of the indoor fan, the control method further comprises: when the temperature IPT of the indoor heat exchanger reaches the low wind speed operation temperature Tlow of the indoor fan, the indoor fan is controlled to operate at a low wind speed, and the low wind speed operation temperature is smaller than the set wind speed operation temperature. Therefore, the running speed of the indoor fan can be adjusted according to the temperature information of the indoor heat exchanger, energy waste caused by high-wind-speed running of the indoor fan can be avoided, the temperature of airflow flowing out of the air outlet can be adjusted according to the temperature information, the indoor temperature field is prevented from being distributed unevenly, and the comfort of the air conditioner can be improved.
It should be noted that the indoor fan may operate at a plurality of wind speed operating positions, for example, the wind speed operating positions include a micro wind position, a low wind position, a medium wind position, and a high wind position, in which the wind speed increases in sequence, the high wind position may be set as the set wind speed of the indoor fan, and when the indoor fan operates at the set wind speed and the fan operating speed decreases by one position, the indoor fan operates at the medium wind position. In addition, it should be noted that breeze, low wind, medium wind, and high wind, which are used herein to indicate degrees, all refer to relative wind speeds, e.g., the wind speed in the low wind range is lower than the wind speed in the low wind range; compared with the high gear, the wind speed of the medium gear is lower than that of the high gear.
In some embodiments, the indoor fan is controlled to stop operating when the temperature IPT of the indoor heat exchanger is less than the low wind speed operating temperature trew. Therefore, the running wind speed of the indoor fan can be further reduced, and the air flow flowing out of the air outlet can meet the comfort requirement of a user.
In some embodiments, after the temperature IPT of the indoor heat exchanger reaches the set wind speed operating temperature tth of the indoor fan, the control method further comprises: when the temperature IPT of the indoor heat exchanger is smaller than the set wind speed operation temperature T, the rotating speed of the indoor fan is controlled to be reduced by one gear, and the opening angle of the air deflector is kept at the second air outlet angle. Therefore, the temperature of the indoor heat exchanger can be improved by reducing the wind speed of the indoor fan, the temperature of the indoor heat exchanger is maintained at the set wind speed operation temperature, and therefore the indoor temperature can be prevented from generating obvious layering effect, and the comfort level of the air conditioner can be improved.
According to some embodiments of the present invention, after the indoor fan speed is reduced by one gear and the opening angle of the air deflector is maintained at the second air outlet angle for the first predetermined time, when the temperature of the indoor heat exchanger is still less than the set air speed operating temperature, the indoor fan speed is controlled to be reduced by one gear, and the opening angle of the air deflector is adjusted to the first air outlet angle. Therefore, the running state of the indoor fan can be timely adjusted in a timing mode, and the temperature of the indoor heat exchanger is prevented from being lower than the set wind speed running temperature for a long time. Further, after the rotating speed of the indoor fan is reduced by one gear and the opening angle of the air deflector is adjusted to the first air outlet angle to operate for a second preset time, when the temperature of the indoor heat exchanger is still lower than the set wind speed operating temperature, the indoor fan is controlled to be in a micro-wind gear until the temperature of the indoor heat exchanger reaches the set wind speed operating temperature.
As shown in fig. 2, according to some embodiments of the present invention, after the indoor fan operates at the set wind speed and the air deflector is opened to the second wind outlet angle and operates for the third predetermined time, the control method further includes when a difference between the set temperature ST and the return air temperature SRT is greater than the first temperature difference threshold, maintaining the opening angle of the air deflector at the second wind outlet angle. Here, the "third predetermined time" may be 4 to 8min, for example, the third predetermined time may be 6 min. The "set temperature" herein may refer to a temperature that the user designates the indoor environment needs to reach, for example, the user may designate the temperature that the indoor environment needs to reach through a remote controller or a control key of an air conditioner.
It should be noted that, when the difference between the set temperature ST and the return air temperature SRT is greater than the first temperature difference threshold T1, the indoor environment is prone to temperature stratification, and thus the comfort is poor due to uneven ambient temperature, in this embodiment, the opening angle of the air deflector is adjusted according to the difference between the set temperature and the return air temperature, that is, the air deflector is kept at the second air outlet angle, when the air deflector is at the second air outlet angle, the air outlet amount of the air conditioner is increased, at this time, the heat exchange efficiency of the indoor heat exchanger can be effectively improved, and then the temperature of the indoor heat exchanger can be reduced, so that the comfort of the air conditioner can be improved.
Further, when the difference between the set temperature ST and the return air temperature SRT is between the first temperature difference threshold T1 and the second temperature difference threshold T2, the air deflector is opened to a third air outlet angle, where the second temperature difference threshold T2 is smaller than the first temperature difference threshold T1, and the third air outlet angle is greater than the second air outlet angle. Furthermore, when the difference between the ST and the SRT is between the second temperature difference threshold T2 and the third temperature difference threshold T3, the air guiding plate is opened to a fourth air outlet angle, wherein the third temperature difference threshold T3 is smaller than the second temperature difference threshold T2, and the fourth air outlet angle is larger than the third air outlet angle. Therefore, the air outlet angle of the air deflector can be adjusted according to the difference value between the set temperature ST and the return air temperature SRT, so that the indoor environment temperature can be conveniently adjusted, the indoor temperature is prevented from generating large layering difference, and the heating comfort of the air conditioner can be improved.
In addition, when the difference between the set temperature ST and the return air temperature SRT is between the third temperature difference threshold T3 and the fourth temperature difference threshold T4, the air deflector is opened to a fifth air outlet angle, wherein the fourth temperature difference threshold T4 is smaller than the third temperature difference threshold T3, and the fifth air outlet angle is larger than the fourth air outlet angle. When the difference value of the ST and the SRT reaches the shutdown temperature, the compressor and the indoor fan stop running, and the opening angle of the air deflector is adjusted to the first air outlet angle.
In some embodiments, when the temperature of the heat exchanger reaches the first predetermined temperature, the opening angle of the air deflector is adjusted to the fourth wind outlet angle. It should be noted that the first predetermined temperature is in a range of 46 ℃ to 50 ℃. For example, the first predetermined temperature may be 48 ℃. To enable real-time monitoring of the difference between the set temperature and the return air temperature, in some embodiments the difference in the temperature of the heat exchangers is compared every fourth predetermined time; and when the difference value of the temperatures of the heat exchangers reaches a set value and lasts for a first duration, adjusting the opening angle of the air deflector to a third air outlet angle.
It should be noted that the first duration may be 1min, and when the difference between the temperatures of the heat exchangers reaches the set value and lasts for the first duration, it is determined that the pressure of the compressor system is still large, and the system pressure needs to be reduced, at this time, the air outlet angle is from the third air outlet angle, which may also be understood as a system pressure relief air outlet angle. And if the temperature IPT of the indoor heat exchanger is continuously increased to 55 ℃, the outdoor fan is turned off to release pressure.
In some embodiments, the outdoor fan is turned off for pressure relief when the temperature of the heat exchanger reaches a second predetermined temperature, the second predetermined temperature being greater than the first predetermined temperature. The second predetermined temperature is 53-57 ℃, for example, the first predetermined temperature may be 55 ℃.
