The embodiment of the invention also provides a control method of the air conditioner, which is applied to the air conditioner.
Referring to fig. 3, an embodiment of a control method of an air conditioner according to the present application is provided. In this embodiment, the method for controlling an air conditioner includes:
step S10, controlling the air pipe machine to perform heating operation and controlling the fresh air device to be started to obtain indoor environmental parameters of the acting space of the air conditioner, state parameters related to fresh air introduced by the fresh air device and the temperature of a heat exchanger of the indoor heat exchanger;
when the air pipe machine is in heating operation, the indoor heat exchanger is in a condensation state, and when the fresh air device is started, outdoor fresh air enters the indoor air duct. Specifically, when the fresh air device comprises a fresh air fan and an air valve arranged at a fresh air outlet, the fresh air fan and the air valve are both opened when the fresh air device is opened.
The air pipe machine can be started to heat and operate and simultaneously can be started to supply fresh air. In addition, the air duct machine can also be controlled to perform heating operation, and the fresh air device is controlled to be started when an opening instruction of the fresh air device is received in the heating operation process of the air duct machine.
The indoor environmental parameters are detected through the indoor parameter detection module. The indoor environment parameters may include an indoor ambient temperature and/or an indoor ambient humidity, among others.
The state parameters related to fresh air can be the operation parameters of the fresh air device and/or the parameters (such as fresh air temperature and/or fresh air humidity and the like) detected by the fresh air parameter detection module. The state parameters may include at least one of the following parameters: the running speed of a fresh air fan in the fresh air device, the opening degree of an air valve in the fresh air device, the fresh air temperature and the fresh air humidity.
The temperature of the heat exchanger can be obtained by acquiring the temperature data currently detected by the temperature sensor.
Step S20, determining a target temperature threshold corresponding to the indoor heat exchanger according to the indoor environment parameters and the state parameters;
the target temperature threshold is specifically a critical value of the indoor heat exchanger coil temperature for distinguishing whether the operating speed of the indoor fan needs to be limited (i.e., whether cold air blows to people or not).
Different indoor environmental parameters and different state parameters correspond to different target temperature thresholds. The corresponding relation between the indoor environment parameter, the state parameter and the target temperature threshold value can be preset, and the corresponding relation can be in the forms of a calculation formula, a mapping relation and the like. Based on the corresponding relation, the target temperature threshold corresponding to the current indoor environment parameter and the state parameter can be determined.
In this embodiment, the number of the target temperature thresholds is more than one, and different target temperature thresholds are used for limiting the indoor fans to operate at different rotating speeds. In other embodiments, the target temperature threshold may be one, and the target temperature threshold may be a critical value for distinguishing whether to turn on the coil temperature of the indoor heat exchanger of the indoor fan.
And step S30, when the temperature of the heat exchanger is smaller than or equal to the target temperature threshold, controlling the indoor fan to operate at a rotating speed smaller than or equal to a preset rotating speed.
When the temperature of the heat exchanger is smaller than or equal to the preset temperature threshold value, the temperature of the indoor heat exchanger is too low, and the running rotating speed of an indoor fan needs to be limited to be not too high so as to prevent cold air from blowing people.
In this embodiment, the preset rotation speed is a preset minimum rotation speed at which the indoor fan is allowed to operate. In other embodiments, the preset rotation speed may also be a target rotation speed required by the indoor fan.
Here, the temperature less than or equal to the preset temperature includes a case where the indoor fan rotation speed is 0 (i.e., the indoor fan is turned off). Specifically, when the temperature of the heat exchanger is less than or equal to the target temperature threshold, the indoor fan can be controlled to be turned off, the indoor fan can be controlled to operate at a preset rotating speed, and the indoor fan can be controlled to operate at any rotating speed between 0 and the preset rotating speed.
When the temperature of the heat exchanger is smaller than or equal to the second temperature threshold and larger than the first temperature threshold, controlling the indoor fan to operate at a first rotating speed; when the temperature of the heat exchanger is smaller than or equal to the first temperature threshold value, the indoor fan is controlled to operate at a second rotating speed, and the first rotating speed and the second rotating speed are both rotating speeds smaller than a preset rotating speed.
Further, after step S20, when the temperature of the heat exchanger is greater than the target temperature threshold, the indoor fan may be controlled to operate at a rotation speed greater than the preset rotation speed. Specifically, the indoor fan can be controlled to be increased to a target rotating speed for operation, wherein the target rotating speed is specifically a wind gear set by a user. Or when the current rotating speed of the indoor fan is greater than the preset rotating speed, the indoor fan can be controlled to maintain the current rotating speed to operate.
The method for controlling the air conditioner is based on the air conditioner comprising the air duct machine and the fresh air device, acquires indoor environment parameters, state parameters related to fresh air introduction and heat exchange temperature of the indoor heat exchanger when the air duct machine is in heating operation and the fresh air device is started, determines a target temperature threshold value of the indoor heat exchanger by combining the indoor environment parameters and the state parameters, and limits the indoor fan not to exceed a preset rotating speed to operate to avoid cold air blowing when the temperature of the heat exchanger is less than or equal to the target temperature threshold value, wherein in the process, the target temperature threshold value of the indoor heat exchanger for cold air prevention control is not a preset fixed value any more and is also determined according to the current indoor working condition state and the fresh air introduction state, the accuracy of the target temperature threshold value is favorably improved, and under the state that the indoor fan is controlled in a speed limit mode based on the target temperature threshold value, the air conditioner can prevent cold wind and avoid unnecessary speed reduction or shutdown of the fan, and the air blowing experience of a user is improved.
Further, based on the above embodiments, another embodiment of the control method of the air conditioner of the present application is provided. In this embodiment, the state parameter includes the operating speed and the fresh air temperature of the fresh air fan in the fresh air device, the indoor environment parameter includes the indoor environment temperature, refer to fig. 4, and step S20 includes:
and step S21, determining the target temperature threshold according to the running rotating speed, the fresh air temperature and the indoor environment temperature.
Different operating speeds, different fresh air temperatures and different indoor environment temperatures correspond to different target temperature thresholds. Specifically, a corresponding relationship between the operating speed, the fresh air temperature, the indoor environment temperature, and the target temperature threshold may be established in advance, and the corresponding relationship may be a calculation formula, a mapping relationship, or the like. And determining a target temperature threshold corresponding to the current running rotating speed, the fresh air temperature and the indoor environment temperature based on the corresponding relation.
Specifically, the temperature difference value between the indoor environment temperature and the fresh air temperature can be determined, and the target temperature threshold value is determined based on the temperature difference value and the operation rotating speed. Different temperature difference values and different operating speeds correspond to different target temperature thresholds. The target temperature threshold may be negatively correlated with the temperature difference value, and the target temperature threshold is negatively correlated with the operating speed. That is, the larger the temperature difference value, the smaller the target temperature threshold value, and the larger the operating rotational speed, the smaller the target temperature threshold value.

Specifically, a first adjustment value corresponding to the operating speed may be determined by calculation or table lookup, a second adjustment value corresponding to the first temperature difference value may be determined by calculation or table lookup, and the temperature adjustment value may be calculated by the first adjustment value and the second adjustment value. The first adjusting value is in positive correlation with the first temperature difference value, and the second adjusting value is in positive correlation with the running rotating speed.

Further, the different temperature variation trends of the indoor heat exchanger correspond to different preset temperature thresholds, specifically, when the temperature variation trend of the indoor heat exchanger is descending, a first preset temperature threshold is used as the preset temperature threshold, and when the temperature variation trend of the indoor heat exchanger is ascending, a second preset temperature threshold is used as the preset temperature threshold. When the target temperature threshold is more than one, the corresponding first preset temperature threshold or the second preset temperature threshold may be more than one.
