The Frequency Tuning parameter controls how often the compressor is tuned. For example, if the current coil temperature is lower than the target coil temperature, the compressor can be controlled to reduce the frequency; the current coil temperature is greater than the target coil temperature, and the compressor can be controlled to increase the frequency; the difference between the current coil temperature and the target coil temperature The larger the temperature difference, the larger the adjustment range of the compression frequency.

In this method, when the fresh air function of the air conditioner is turned on, the outdoor fresh air is mixed with the air after the heat exchange of the indoor heat exchanger and then sent into the room. When the fresh air function is running and the fresh air function is turned on, the air conditioner is controlled based on the target coil temperature of the indoor heat exchanger determined by the fresh air parameters, so as to ensure that the air temperature of the air conditioner can reach above the target temperature, and avoid mixing indoor and outdoor air into the room The air temperature is too low to improve indoor user comfort.
进一步的，基于上述实施例，提出本申请空调器的控制方法另一实施例。在本实施例中，所述新风参数包括新风风机转速和新风温度，参照图3，所述步骤S20包括：Further, another embodiment of the air conditioner control method of the present application is proposed based on the above embodiments.

步骤S21，根据所述新风风机转速和所述新风温度确定所述目标盘管温度。Step S21, determining the target coil temperature according to the rotation speed of the fresh air fan and the fresh air temperature.
不同的新风风机转速和不同的新风温度对应不同的目标盘管温度。具体的，新风温度越大则目标盘管温度越小，新风风机转速越大则目标盘管温度越小；反而言之，新风温度越小则目标盘管温度越大，新风风机转速越小则目标盘管温度越大。Different fresh air fan speeds and different fresh air temperatures correspond to different target coil temperatures. Specifically, the higher the fresh air temperature is, the lower the target coil temperature is, and the higher the fresh air fan speed is, the lower the target coil temperature is; The higher the target coil temperature.
基于此，可通过将新风风机转速和新风温度代入预设公式中计算得到目标盘管温度，也可将新风风机转速和新风温度查询预设映射表将匹配到的结果作为目标盘管温度。Based on this, the target coil temperature can be calculated by substituting the fresh air fan speed and fresh air temperature into the preset formula, or the fresh air fan speed and fresh air temperature can be queried in the preset mapping table, and the matched result can be used as the target coil temperature.

The rotation speed of the fresh air fan and the fresh air temperature can be calculated or looked up in a table to obtain the corresponding first temperature correction value. Specifically, in this embodiment, the difference between the target temperature and the first temperature correction value can be used as the target coil temperature. The greater the fresh air fan speed and the fresh air temperature, the greater the corresponding first temperature correction value, and the target disk The lower the tube temperature. In other embodiments, the ratio or product of the target temperature and the first temperature correction value may also be used as the target coil temperature.
在本实施例中，新风风机转速不同、新风温度不同则会导致新风与室内空气混合后的出风温度不同，基于此，结合新风风机转速与新风温度所确定的室内换热器的目标盘管温度对空调器进行调控，有利于保证室内换热器换热后的空气与新风混合后可使空调器的出风温度精准地达到目标温度以上，以进一步确保新风引入过程中空调的出风温度不会过低，保证用户舒适性。其中，结合新风温度与新风风机转速所确定的温度修正值对空调出风的目标 温度进行修正后的温度作为目标盘管温度，从而进一步提高所确定的目标盘管温度的准确性，以保证目标盘管温度控制下空调器的出风温度可精准地达到目标温度以上。In this embodiment, different fresh air fan speeds and fresh air temperatures will result in different outlet air temperatures after the fresh air is mixed with indoor air. Based on this, the target coil of the indoor heat exchanger determined by combining the fresh air fan speed and the fresh air temperature The temperature is adjusted to the air conditioner, which is beneficial to ensure that the air after the heat exchange of the indoor heat exchanger is mixed with the fresh air, so that the air outlet temperature of the air conditioner can accurately reach the target temperature, so as to further ensure the air outlet temperature of the air conditioner during the introduction of fresh air Not too low to ensure user comfort. Among them, the temperature correction value determined by combining the fresh air temperature and the fresh air fan speed is used to correct the target temperature of the air-conditioning outlet air as the target coil temperature, thereby further improving the accuracy of the determined target coil temperature to ensure the target temperature. Under the coil temperature control, the outlet air temperature of the air conditioner can be accurately reached above the target temperature.
进一步的，在本实施例中，确定第一温度修正值的过程具体如下：Further, in this embodiment, the process of determining the first temperature correction value is specifically as follows:
根据所述空调器的室内风机转速和所述新风风机转速确定第二温度修正值；根据所述第二温度修正值修正所述新风温度，获得所述第一温度修正值。A second temperature correction value is determined according to the indoor fan speed of the air conditioner and the fresh air fan speed; and the fresh air temperature is corrected according to the second temperature correction value to obtain the first temperature correction value.
这里的室内风机转速具体为空调器的室内风机当前的运行转速。不同的室内风机转速和不同的新风风机转速对应不同的第二温度修正值。具体的，可根据室内风机转速和新风风机转速可通过计算或查表等方式得到对应的第二温度修正值。The indoor fan speed here specifically refers to the current operating speed of the indoor fan of the air conditioner. Different indoor fan speeds and different fresh air fan speeds correspond to different second temperature correction values. Specifically, the corresponding second temperature correction value can be obtained through calculation or table lookup according to the speed of the indoor fan and the speed of the fresh air fan.
在本实施例中，根据新风风机转速与室内风机转速的比值确定第二温度修正值。具体的，可将新风风机转速与室内风机转速的比值直接作为第二温度修正值。也可将新风风机转速与室内风机转速的比值通过预设系数进行调整后的结果作为第二温度修正值。In this embodiment, the second temperature correction value is determined according to the ratio of the rotation speed of the fresh air fan to the rotation speed of the indoor fan. Specifically, the ratio of the rotation speed of the fresh air fan to the rotation speed of the indoor fan may be directly used as the second temperature correction value. The ratio of the rotation speed of the fresh air fan to the rotation speed of the indoor fan may also be adjusted by a preset coefficient as the second temperature correction value.
