[0040] In the prior art, the air conditioner generally introduces outdoor fresh air into the indoor to maintain the freshness of the indoor environment air.

Specifically, the fresh air parameter detection module 3 can comprise a temperature sensor and / or a humidity sensor, the temperature sensor can be used to detect the fresh air temperature, and the humidity sensor can be used to detect the fresh air humidity.

[0047] Further, in the embodiment, the air conditioner can further comprise a temperature sensing bag, which can be arranged in the indoor heat exchanger coil to detect the current coil temperature of the indoor heat exchanger.

The above-mentioned fresh air fan 1 and fresh air parameter detection module 3 can be connected with the control device. In addition, the above-mentioned indoor fan 2 and temperature sensing bag can also be connected with the control device.

[0049] In the embodiments of the present application, with reference to Figure 1 , the control device of the air conditioner comprises a processor 1001 (such as a CPU), a memory 1002, etc. The memory 1002 can be a high-speed RAM memory, or a stable memory (non-volatile memory) such as a disk memory. The memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0050] Those skilled in the art can understand that Figure 1 The device structure shown in the embodiments does not constitute a limitation on the device, and can include more or fewer components than shown, or combine certain components, or different component arrangements.

[0051] As shown in Figure 1 , the memory 1002 as a computer readable storage medium can include a control program of the air conditioner. In the device shown in Figure 1 , the processor 1001 can be used to call the control program of the air conditioner stored in the memory 1002, and perform the related step operations of the control method of the air conditioner in the following embodiments.

[0052] The embodiments of the present application also provide a control method of an air conditioner, which is applied to control the above-mentioned air conditioner.

[0053] With reference to Figure 2 , an embodiment of the control method of the air conditioner is proposed. In the embodiment, the control method of the air conditioner comprises:

[0054] Step S10, when the air conditioner is in a refrigeration operation and the fresh air function is turned on, acquiring a fresh air parameter; when the fresh air function is turned on, the air after heat exchange of the indoor heat exchanger of the air conditioner is mixed with outdoor fresh air and sent into the indoor;

[0055] In the refrigeration operation of the air conditioner, the fresh air function can be started when a user input start fresh air instruction is received, or the fresh air function can be started when it is monitored that the air in the indoor environment does not reach a preset quality.

[0056] The fresh air parameter is specifically a characteristic parameter representing the fresh air introduction condition. The fresh air parameter can include fresh air temperature, fresh air humidity, and / or fresh air fan speed, etc.

[0057] The fresh air parameter can be obtained by acquiring data detected by a fresh air parameter detection module arranged in a fresh air duct, or can be obtained by acquiring an operating parameter of a component related to the introduction of fresh air (such as a fresh air fan, etc.).

[0058] Step S20, determining a target coil temperature of the indoor heat exchanger according to the fresh air parameter;

[0059] Different fresh air parameters correspond to different target coil temperatures of the indoor heat exchanger. Specifically, a corresponding relationship between the fresh air parameter and the target coil temperature can be established in advance, which can be a calculation formula, a mapping relationship, etc. Based on the corresponding relationship, the target coil temperature corresponding to the current fresh air parameter can be determined. For example, a calculation formula between the fresh air parameter and the coil temperature is set in advance, the current detected fresh air parameter can be substituted into the calculation formula, and the result calculated can be used as the target coil temperature. Alternatively, a mapping table of the fresh air parameter and the coil temperature can also be set in advance, and the result obtained by querying the mapping table with the current fresh air parameter can be used as the target coil temperature.

[0060] Step S30, controlling the air conditioner to operate according to the target coil temperature, so that the air outlet temperature of the air conditioner is greater than the target temperature.

[0061] Specifically, the compressor, the indoor fan, and / or the electronic expansion valve, etc. are controlled to operate according to the target coil temperature, so that the actual air outlet temperature of the air conditioner can reach above the target temperature.

[0062] In the embodiment, the running frequency of the compressor of the air conditioner is adjusted according to the target coil temperature, so that the temperature of the indoor heat exchanger reaches the target coil temperature. Specifically, the current coil temperature of the indoor heat exchanger is detected, the frequency adjustment parameter (such as the frequency adjustment direction and / or the frequency adjustment amplitude, etc.) of the compressor is determined according to the current coil temperature and the target coil temperature, and the frequency adjustment parameter is used to control the compressor to adjust the frequency. For example, when the current coil temperature is less than the target coil temperature, the compressor is controlled to run at a lower frequency; when the current coil temperature is greater than the target coil temperature, the compressor is controlled to run at a higher frequency; and the greater the temperature difference between the current coil temperature and the target coil temperature, the greater the adjustment amplitude of the compressor frequency. In other embodiments, the coil temperature of the indoor heat exchanger can also be adjusted to the target coil temperature by an electronic expansion valve. For example, when the current coil temperature is less than the target coil temperature, the opening of the electronic expansion valve is controlled to increase; and when the current coil temperature is greater than the target coil temperature, the opening of the electronic expansion valve is controlled to decrease.

[0063] The target temperature is specifically an air outlet temperature value that makes the user feel comfortable and not cold. The target temperature can be a pre-set fixed temperature value, can be a parameter determined based on the actual running conditions of the air conditioner, or can be a temperature determined based on a user input setting parameter. For example, the target temperature can be determined according to the outdoor environment temperature or the indoor environment temperature when the refrigeration operation is started. In the embodiment, the value range of the target temperature is [18℃, 23℃], for example, 20℃.

[0064] The control method of the air conditioner provided in the embodiment of the application is used to mix the air after the outdoor fresh air and the air after the heat exchange of the indoor heat exchanger, and then send the mixed air into the room. On this basis, when the air conditioner is running in the refrigeration mode and the fresh air function is turned on, the target coil temperature of the indoor heat exchanger is determined based on the fresh air parameter, and the air conditioner is controlled to run based on the target coil temperature, so that the air outlet temperature of the air conditioner can reach the target temperature or above, the temperature of the air mixed by the indoor and outdoor air is prevented from being too low, and the user comfort in the room is improved.

[0065] Further, based on the above-mentioned embodiment, another embodiment of the control method of the air conditioner of the application is provided. In the embodiment, the fresh air parameter includes the fresh air fan speed and the fresh air temperature, and the step S20 includes: Figure 3

[0066] The step S21 is used to determine the target coil temperature according to the fresh air fan speed and the fresh air temperature.

[0067] ​Different fresh air fan speeds and different fresh air temperatures correspond to different target coil temperatures. Specifically, the higher the fresh air temperature, the lower the target coil temperature; the higher the fresh air fan speed, the lower the target coil temperature. Conversely, the lower the fresh air temperature, the higher the target coil temperature; the lower the fresh air fan speed, the higher the target coil temperature.

[0068] Based on this, the target coil temperature can be calculated by substituting the fresh air fan speed and fresh air temperature into a preset formula, or the fresh air fan speed and fresh air temperature can be queried from a preset mapping table and the matched result can be used as the target coil temperature.

[0069] Specifically, in this embodiment, the process of determining the target coil temperature using the fresh air temperature and the fresh air fan speed is as follows: A first temperature correction value is determined based on the fresh air fan speed and the fresh air temperature; the target temperature is then corrected based on the first temperature correction value to obtain the target coil temperature. The fresh air fan speed and fresh air temperature can be obtained through calculation or table lookup. 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 higher the fresh air fan speed and fresh air temperature, the larger the corresponding first temperature correction value, and thus the lower the target coil temperature. In other embodiments, the ratio or product of the target temperature and the first temperature correction value can also be used as the target coil temperature.

[0070] In this embodiment, different fresh air fan speeds and fresh air temperatures will result in different outlet air temperatures after the fresh air mixes with indoor air. Therefore, by combining the target coil temperature of the indoor heat exchanger determined by the fresh air fan speed and fresh air temperature, the air conditioner is regulated. This helps ensure that the outlet air temperature of the air conditioner accurately reaches or exceeds the target temperature after the air after heat exchange in the indoor heat exchanger mixes with the fresh air, further ensuring that the outlet air temperature during fresh air introduction is not too low, thus guaranteeing user comfort. Specifically, the target coil temperature is obtained by correcting the air conditioner's outlet air temperature based on the temperature correction value determined by the fresh air temperature and fresh air fan speed. This further improves the accuracy of the determined target coil temperature, ensuring that the air conditioner's outlet air temperature accurately reaches or exceeds the target temperature under target coil temperature control.

[0071] Furthermore, in this embodiment, the process of determining the first temperature correction value is as follows:

[0072] A second temperature correction value is determined based on the indoor fan speed and the fresh air fan speed of the air conditioner; the fresh air temperature is corrected based on the second temperature correction value to obtain the first temperature correction value.

[0073] The indoor fan speed here is specifically the current running 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 indoor fan speed and the fresh air fan speed.

[0074] In this embodiment, the second temperature correction value is determined according to the ratio of the fresh air fan speed to the indoor fan speed. Specifically, the ratio of the fresh air fan speed to the indoor fan speed can be directly taken as the second temperature correction value. Alternatively, the result obtained by adjusting the ratio of the fresh air fan speed to the indoor fan speed by a preset coefficient can be taken as the second temperature correction value.

[0075] In this embodiment, the product of the fresh air temperature and the second temperature correction value is taken as the first temperature correction value. In other embodiments, the sum, difference or ratio of the fresh air temperature and the second temperature correction value can also be taken as the first temperature correction value.

[0076] In this embodiment, since the running speeds of the indoor fan and the fresh air fan both affect the heat exchange effect during the mixing of fresh air and indoor air in the mixing chamber, the result obtained by correcting the fresh air temperature in combination with the indoor fan speed and the fresh air fan speed is taken as the temperature correction value corresponding to the target temperature, which can ensure that the determined target coil temperature can make the temperature of the air mixed by the fresh air and the indoor air of the air conditioner reach the target temperature accurately, further ensuring the satisfaction of user comfort.

[0077] Further, in this embodiment, the process of determining the second temperature correction value is specifically as follows: determining a first air volume according to the first air volume conversion coefficient and the indoor fan speed, determining a second air volume according to the second air volume conversion coefficient and the fresh air fan speed; determining the ratio of the second air volume to the first air volume; and determining the second temperature correction value according to the ratio.

[0078] The first air volume conversion coefficient represents the conversion relationship between the running speed of the indoor fan and the air volume of the indoor air introduced by the indoor fan. The second air volume conversion coefficient represents the conversion relationship between the running speed of the fresh air fan and the fresh air volume introduced by the fresh air fan.

[0079] Specifically, the first air volume can be calculated by the first air volume conversion coefficient and the indoor fan speed, and the second air volume can be calculated by the second air volume conversion coefficient and the fresh air fan speed. Specifically, the ratio of the second air volume to the first air volume can be directly taken as the second temperature correction value; alternatively, the result obtained by correcting the ratio of the second air volume to the first air volume by a preset correction coefficient can be taken as the second temperature correction value.

[0080] In the embodiment, the first air volume of the indoor air passing through the heat exchanger and the second air volume of the fresh air are respectively converted based on the rotation speed of the indoor fan and the rotation speed of the fresh air fan, and based on this, the heat exchange effect of the fresh air and the indoor air in the mixing chamber can be accurately reflected by the ratio of the second air volume to the first air volume, and the outlet air temperature of the mixed air conditioner can be accurately reflected, and based on this, the target coil temperature of the indoor heat exchanger is determined by the correction value determined by the ratio, so that the cooling capacity output by the indoor heat exchanger under the control of the target coil temperature can ensure that the outlet air temperature of the mixed fresh air and indoor air can reach above the target temperature, and further ensure the comfort of the indoor user during the fresh air introduction process.

[0081] Further, in the embodiment, the process of determining the first temperature correction value is specifically as follows:

[0082] The first humidity of the fresh air and the second humidity of the air after heat exchange of the indoor heat exchanger are obtained; a target corresponding relationship is determined according to the first humidity and the second humidity; the first temperature correction value corresponding to the rotation speed of the fresh air fan and the fresh air temperature is determined based on the target corresponding relationship. Specifically, the corresponding relationship between the rotation speed of the fresh air fan, the fresh air temperature and the first temperature correction value can be pre-set to more than one, and in the more than one corresponding relationship, different first humidities and second humidities correspond to different corresponding relationships. Specifically, the humidity corresponding to the fresh air can be divided into a plurality of first humidity intervals, and the humidity of the air after heat exchange of the indoor heat exchanger can be divided into a plurality of second humidity intervals, and different first humidity intervals and different second humidity intervals correspond to different corresponding relationships. Based on this, the corresponding relationship corresponding to the two humidity intervals can be determined as the target corresponding relationship by determining the humidity intervals of the first humidity and the second humidity. Alternatively, a parameter (such as the deviation or ratio of the first humidity and the second humidity) representing the outlet air humidity of the air conditioner can be calculated according to the first humidity and the second humidity, and different parameters correspond to different corresponding relationships. Based on this, the corresponding relationship corresponding to the first humidity and the second humidity can be obtained as the target corresponding relationship by calculating the parameter representing the first humidity and the second humidity.

[0083] Wherein, when the second temperature correction value is determined in the process of determining the first temperature correction value, the target corresponding relationship here can be the corresponding relationship between the rotation speed of the indoor fan, the rotation speed of the fresh air fan and the second temperature correction value.

[0084] In the embodiment, the target corresponding relationship is obtained by combining the humidity of the fresh air and the humidity of the air after heat exchange to determine the temperature correction value of the target temperature to determine the target coil temperature, so that when the air conditioner is controlled by the determined target coil temperature, the outlet air temperature can be ensured to be above the target temperature, and condensation can be prevented in the mixing chamber, thereby ensuring the comfort of the outlet air while preventing air conditioner condensation.

[0085] Further, in order to better understand the target coil temperature determination process involved in the present embodiment, the scheme involved in the present embodiment is described below with a specific application. Specifically, the target coil temperature corresponding to the fresh air fan speed and fresh air temperature can be calculated by the following formula:

[0086]

[0087] wherein, T2 柔2 : target coil temperature; T2 柔1 : target temperature of air conditioner outlet air, which can be 20℃;

[0088] T 新 : fresh air temperature; k 新 : second air volume conversion coefficient; k1: first air volume conversion coefficient;

[0089] N 新 : fresh air fan speed; N1: indoor fan speed of air conditioner; χ: correction coefficient.

[0090] Based on this, by substituting the relevant parameters into the above formula, the target coil temperature of the current air conditioner can be calculated.

[0091] Further, based on any of the above embodiments, another embodiment of the control method of the air conditioner of the present application is proposed. In the present embodiment, referring to Figure 4 , step S20 comprises:

[0092] Step S201, obtaining the set temperature of the air conditioner and the guide angle of the air guide member of the air conditioner outlet;

[0093] The air outlet direction and / or air volume of the air conditioner outlet are different under different guide angles of the air guide member.

[0094] The set temperature is specifically the target temperature value that the indoor environment needs to reach when the air conditioner is running in cooling mode. The set temperature can be determined by obtaining the user instruction, or it can be set based on the monitoring of the indoor scene by the air conditioner.

[0095] Step S202, obtaining a preset corresponding relationship according to the set temperature and the guide angle;

[0096] The different preset corresponding relationships correspond to different set temperatures and different air guide angles. The preset corresponding relationship herein is a corresponding relationship between the fresh air parameters and the target coil temperature. Specifically, when the fresh air parameters include the fresh air fan speed and the fresh air temperature, the preset corresponding relationship herein is specifically a corresponding relationship between the fresh air fan speed, the fresh air temperature and the target coil temperature. When the first temperature correction value needs to be determined in the process of determining the target coil temperature through the fresh air fan speed and the fresh air temperature, the preset corresponding relationship herein can specifically include a corresponding relationship between the fresh air fan speed, the indoor fan speed and the second temperature correction value, a corresponding relationship between the second temperature correction value, the fresh air temperature and the first temperature correction value, in addition to a corresponding relationship between the first temperature correction value, the target temperature and the target coil temperature. When the second temperature correction value needs to be determined in the process of determining the first temperature correction value, the preset corresponding relationship can include the corresponding relationship between the fresh air fan speed, the indoor fan speed and the second temperature correction value, the corresponding relationship between the second temperature correction value, the fresh air temperature and the first temperature correction value, in addition to the corresponding relationship between the first temperature correction value, the target temperature and the target coil temperature.

[0097] In step S203, the target coil temperature corresponding to the fresh air parameter is determined based on the preset corresponding relationship.

[0098] Based on the determined preset corresponding relationship, the target coil temperature corresponding to the current fresh air parameter can be determined.

[0099] In the embodiment, since the set temperature is different, the user's demand and feeling for the air outlet temperature are different, and since the air guide angle is different, the influence of the air outlet temperature on the user is different. Therefore, the preset corresponding relationship obtained based on the set temperature and the air guide angle is used to determine the target coil temperature corresponding to the current fresh air parameter, so that the determined target coil temperature can be accurate, and the air outlet temperature of the air conditioner under the control of the target coil temperature can accurately meet the comfort demand of the indoor user.

[0100] In addition, the embodiment of the present application also provides a computer readable storage medium, and the computer readable storage medium stores a control program of an air conditioner. When the control program of the air conditioner is executed by a processor, the related steps of any one of the embodiments of the control method of the air conditioner are implemented.
