First embodiment
The embodiment of the invention provides an outdoor fan control method which is applied to the air conditioner 1 and used for reducing noise of the air conditioner 1 after the air conditioner 1 enters a sleep mode. Fig. 2 is a flowchart of an outdoor fan control method according to an embodiment of the present invention. The outdoor fan control method comprises the following steps:
step S201, judging whether the air conditioner 1 enters a sleep operation mode, if so, executing step S202; if not, step S201 is re-executed.
Since it is indicated that the user is not in the sleep state when the air conditioner 1 does not enter the sleep operation mode, the cooling should be mainly ensured at this time, and therefore, the subsequent noise reduction operation is not required.
In step S202, the compressor operation time is acquired.
Meanwhile, even though the air conditioner 1 has entered the sleep operation mode, it usually takes time for a user to sleep, and it also takes time to adjust the indoor ambient temperature to a temperature suitable for the user to sleep, so it is also necessary to acquire the compressor operation time to determine the time for the air conditioner 1 to enter the sleep operation mode.
Step S203, judging whether the running time of the compressor is greater than or equal to a preset time threshold, if so, executing step S204; if not, step S203 is re-executed.
Since the user may not be asleep or the indoor ambient temperature has not yet reached the temperature suitable for the sleep of the user when the operation time of the compressor is less than the preset time threshold, the user's needs should be satisfied first by mainly ensuring the refrigeration at this time.
Step S204, an indoor ambient temperature and an outdoor ambient temperature are acquired.
When the operation time of the compressor is greater than or equal to the preset time threshold, it indicates that the user may have fallen asleep or the indoor ambient temperature has reached a temperature suitable for the user to sleep, and at this time, the wind speed of the outdoor fan 5 may be considered to be adjusted, so as to achieve the purpose of reducing noise.
In step S205, the wind speed of the outdoor fan 5 is adjusted according to the indoor ambient temperature and the outdoor ambient temperature.
Please refer to fig. 3, which is a flowchart illustrating the step S205. The step S205 includes:
in sub-step S2051, a first temperature difference between the indoor ambient temperature and the outdoor ambient temperature is calculated.
In an alternative embodiment, the outdoor ambient temperature minus the indoor ambient temperature is taken as the first temperature difference; since the outdoor ambient temperature is higher than the indoor ambient temperature in summer, the first temperature difference is a positive value.
And a substep S2052 of adjusting the wind speed of the outdoor fan 5 according to the first temperature difference.
Specifically, please refer to fig. 4, which is a flowchart illustrating the sub-step S2052.
Substep S20521, determining whether the first temperature difference is greater than or equal to a preset first temperature threshold, if yes, executing substep S20522; if not, then sub-step S20523 is performed.
And a substep S20522 of controlling the outdoor fan 5 to operate at the first wind speed.
And when the first temperature difference is greater than or equal to a preset first temperature threshold value, controlling the outdoor fan 5 to operate at a first wind speed.
The first temperature difference is larger than or equal to the preset first temperature threshold value, which indicates that the outdoor environment temperature is far higher than the indoor environment temperature at the moment, so that the exhaust pressure of the compressor is higher and the room load degree is higher at the moment, and the outdoor fan 5 is controlled to operate at the first air speed at the moment, so that the heat exchange effect of the outdoor heat exchanger is guaranteed, and the comfortable indoor environment temperature is created for users.
In an alternative embodiment, the controller 2 is further configured to control the outdoor fan 5 to operate at a second wind speed when the first temperature difference is smaller than the preset first temperature threshold, wherein the second wind speed is smaller than the first wind speed.
Since the first temperature difference is smaller than the preset first temperature threshold, which indicates that the indoor ambient temperature is close to the outdoor ambient temperature, the discharge pressure of the compressor is lower and the room load degree is lower, and therefore the outdoor fan 5 is controlled to operate at the second lower wind speed, so as to reduce the noise generated when the outdoor fan 5 operates and reduce the power consumption of the air conditioner 1.
In another alternative embodiment, the controller 2 is configured to perform sub-step S20523 and subsequent steps when the first temperature difference is less than a preset first temperature threshold. The reason is that when the first temperature difference is smaller than the preset first temperature threshold, the room load degree is directly considered to be smaller so as to reduce the wind speed of the outdoor fan 5, and the error is larger, which may cause the refrigeration effect of the air conditioner 1 to be damaged, so that the outdoor coil temperature is further acquired to calculate the supercooling degree, and the load of the outdoor heat exchanger is determined based on the supercooling degree, so as to determine the room load degree more accurately.
And substep S20523, obtaining the outdoor coil temperature.
When the first temperature difference is smaller than a preset first temperature threshold value, the indoor environment temperature is close to the outdoor environment temperature, but in order to determine the room load degree more accurately, the outdoor coil temperature is further obtained at the moment so as to calculate the supercooling degree.
In an alternative embodiment, the first temperature threshold is 3 ℃. Generally, when the temperature difference between the outdoor ambient temperature and the indoor ambient temperature is 3 ℃, the compressor of the air conditioner 1 consumes less power and the air conditioner 1 consumes less power.
And a substep S20524 of adjusting the wind speed of the outdoor fan 5 based on the outdoor coil temperature and the outdoor ambient temperature.
Specifically, a second temperature difference formed by the temperature of the outdoor coil and the temperature of the outdoor environment is calculated; it should be noted that the second temperature difference is the supercooling degree. Generally, the larger the supercooling degree is, the smaller the load of the outdoor heat exchanger is; the smaller the supercooling degree, the larger the load of the outdoor heat exchanger.
It should be noted that, in this embodiment, a first wind speed and a second wind speed are preset for the outdoor fan 5, and the first wind speed is greater than the second wind speed; when different conditions are satisfied, the outdoor fan 5 may be operated at the first wind speed or the second wind speed, respectively.
Specifically, when the second temperature difference is smaller than a preset second temperature threshold, the outdoor fan 5 is controlled to operate at the first wind speed.
It can be understood that, when the second temperature difference is smaller than the preset second temperature threshold, it indicates that the temperature of the outdoor coil is further away from the outdoor ambient temperature, so that the load of the outdoor heat exchanger of the air conditioner 1 is larger at this time, and the room load degree is larger, so that the outdoor fan 5 is controlled to operate at the higher first wind speed at this time, the heat exchange effect of the outdoor heat exchanger is ensured, and a comfortable indoor ambient temperature is created for the user.
And when the second temperature difference is greater than or equal to a preset second temperature threshold value, controlling the outdoor fan 5 to operate at a second wind speed.
When the second temperature difference is greater than or equal to the preset second temperature threshold, the temperature of the outdoor coil pipe is close to the outdoor environment temperature, and the heat exchange pressure of the outdoor heat exchanger of the air conditioner 1 is low, so that the room load degree is low, the outdoor fan 5 is controlled to reduce the wind speed at the moment, the air conditioner operates at the second wind speed, the purpose of reducing noise is achieved, and better use experience is provided for users; meanwhile, the outdoor fan 5 operates at a lower wind speed, so that the effect of saving power consumption can be achieved.
In an alternative embodiment, the second temperature threshold is 5 ℃.
