The air deflector assembly 310 and the lower air deflector assembly 320 are separately driven by different motors to separately control the air supply; the upper air deflector assembly 310 and the lower air deflector assembly 320 may be located on the same working plane ( The working plane is not an absolute plane. It is only used to describe the spatial position of the two air deflectors. It can also be set in different working planes according to actual needs. At this time, the air outlet 110 is divided into an upper air outlet 111 and a lower air outlet 112, and the air is controlled by the upper air deflector assembly 310 and the lower air deflector assembly 320, respectively. By providing the air deflector assembly as the upper air deflector assembly 310 and the lower air deflector assembly 320, the air supply conditions of the upper and lower portions of the air outlet 110 can be adjusted according to actual needs. When the air deflector is a windless wind deflector, the upper air deflector assembly 310 and the lower air deflector assembly 320 can realize the windless air supply of the upper air outlet 111 and the lower air outlet 112, respectively. Taking the wind deflector as the windless wind deflector as an example, when the lower wind deflector assembly 320 is closed under a certain working condition, the windless air supply of the lower air outlet 112 is realized, and the traditional air outlet 111 is sent. wind. During this process, the air supply speed of the upper and lower air outlets 112 of the wind wheel is equivalent, and the wind pressure at the lower part of the air duct is gradually increased due to the wind output of the lower air outlet 112, and the wind pressure at the lower part of the air duct is greater than that of the upper air duct. When the wind pressure is applied, a part of the airflow in the lower part of the air duct flows to the upper part of the air duct, so that the wind pressure in the upper part of the air duct increases, so that the wind speed of the upper air outlet 111 is increased, and the air supply distance is also increased. Similarly, when the upper air deflector assembly 310 is closed under a certain working condition, the windless air supply of the upper air outlet 111 and the conventional air supply of the upper air outlet 111 are realized. During this process, the air supply speed of the upper and lower air outlets 112 of the wind wheel is equivalent, and the wind pressure at the upper part of the air duct is gradually increased due to the obstruction of the air outlet 111, and the wind pressure at the upper part of the air duct is greater than that of the lower air duct. When the wind pressure is applied, a part of the airflow in the upper part of the air duct flows to the lower part of the air duct, so that the wind pressure in the lower part of the air duct increases, so that the wind speed of the air outlet 112 is increased, and the air supply distance is also increased. Of course, when both the upper air deflector assembly 310 and the lower air deflector assembly 320 are closed for windless air supply, the wind pressure in the entire air duct is increased.

The louver assembly may include a top louver assembly 410 and a lower louver assembly 420, and the upper louver assembly 410 and the lower louver assembly 420 are both disposed at the air outlet 110 along the length of the air outlet 110; the upper louver assembly 410 and the lower louver assembly 420 are respectively Different motors are separately driven to control the air supply separately; the upper louver assembly 410 and the lower louver assembly 420 may be located in the same working plane (the working plane is not an absolute plane, only used to describe the spatial position of the two sets of louvers), or may be Actually need to be set in different work planes. At this time, the air outlet 110 is divided into an upper air outlet 111 and a lower air outlet 112, and the air is controlled by the upper louver assembly 410 and the lower louver assembly 420, respectively. By arranging the louver assembly as the upper louver assembly 410 and the lower louver assembly 420, the air supply conditions of the upper and lower portions of the air outlet 110 can be adjusted according to actual needs. When the louver is a windless louver, the upper louver assembly 410 and the lower louver assembly 420 can realize the windless sensible air supply of the upper air outlet 111 and the lower air outlet 112, respectively. Taking the louver as a windless louver as an example, when the lower louver assembly 420 is closed under a certain working condition, the windless air supply of the lower air outlet 112 and the conventional air supply of the upper air outlet 111 are realized. During this process, the air supply speed of the upper and lower air outlets 112 of the wind wheel is equivalent, and the wind pressure at the lower part of the air duct is gradually increased due to the wind output of the lower air outlet 112, and the wind pressure at the lower part of the air duct is greater than that of the upper air duct. When the wind pressure is applied, a part of the airflow in the lower part of the air duct flows to the upper part of the air duct, so that the wind pressure in the upper part of the air duct increases, so that the wind speed of the upper air outlet 111 is increased, and the air supply distance is also increased. Similarly, when the upper louver assembly 410 is closed under a certain working condition, the windless air supply of the upper air outlet 111 and the conventional air supply of the lower air outlet 112 are realized. During this process, the air supply speed of the upper and lower air outlets of the wind wheel is equivalent. Because the air outlet of the upper air outlet 111 is blocked, the wind pressure at the upper part of the air duct gradually increases, and the wind pressure at the upper part of the air duct is greater than that of the lower air duct. When the wind pressure is applied, a part of the airflow in the upper part of the air duct flows to the lower part of the air duct, so that the wind pressure in the lower part of the air duct increases, so that the wind speed of the air outlet 112 is increased, and the air supply distance is also increased. Of course, when both the upper louver assembly 410 and the lower louver assembly 420 are closed for windless air supply, the wind pressure in the entire air passage is increased.

The door body assembly may include an upper door body assembly 510 and a lower door body assembly 520, and the upper door body assembly 510 and the lower door body assembly 520 are both disposed at the air outlet 110 along the length of the air outlet 110; the upper door body assembly 510 and the lower door body The components 520 are separately driven by different motors to separately control the air supply; the upper door body assembly 510 and the lower door body assembly 520 can be located on the same working plane (the working plane is not an absolute plane, and is only used to illustrate the spatial position of the two groups of door bodies). ), can also be set in different work planes according to actual needs. At this time, the air outlet 110 is divided into an upper air outlet 111 and a lower air outlet 112, and the air is controlled by the upper door assembly 510 and the lower door assembly 520, respectively. By providing the door body assembly as the upper door body assembly 510 and the lower door body assembly 520, the air supply conditions of the upper and lower portions of the air outlet 110 can be adjusted according to actual needs. When the door body is a windless door body, the upper door body assembly 510 and the lower door body assembly 520 can realize the windless air supply of the upper air outlet 111 and the lower air outlet 112, respectively. Taking the door body as the windless door body as an example, when the lower door body assembly 520 is closed under a certain working condition, the windless air supply of the lower air outlet 112 and the conventional air supply of the upper air outlet 111 are realized. During this process, the air supply speed of the upper and lower air outlets 112 of the wind wheel is equivalent, and the wind pressure at the lower part of the air duct is gradually increased due to the wind output of the lower air outlet 112, and the wind pressure at the lower part of the air duct is greater than that of the upper air duct. When the wind pressure is applied, a part of the airflow in the lower part of the air duct flows to the upper part of the air duct, so that the wind pressure in the upper part of the air duct increases, so that the wind speed of the upper air outlet 111 is increased, and the air supply distance is also increased. Similarly, when the upper door assembly 510 is closed under a certain working condition, the windless air supply of the upper air outlet 111 and the conventional air supply of the lower air outlet 112 are realized. During this process, the air supply speed of the upper and lower air outlets of the wind wheel is equivalent. Because the air outlet of the upper air outlet 111 is blocked, the wind pressure at the upper part of the air duct gradually increases, and the wind pressure at the upper part of the air duct is greater than that of the lower air duct. When the wind pressure is applied, a part of the airflow in the upper part of the air duct flows to the lower part of the air duct, so that the wind pressure in the lower part of the air duct increases, so that the wind speed of the air outlet 112 is increased, and the air supply distance is also increased. Of course, when the upper door body assembly 510 and the lower door body assembly 520 are both closed for windless air supply, the wind pressure in the entire air passage is increased.

The control method of the air conditioner will be mainly described below.

The control method of the air conditioner includes the following steps:

S10, receiving a windless sense control command, and entering a windless air supply mode;

The receiving windlessness control command may be a control command sent by the receiving user through the mobile terminal or pressing the command, or may be a control command acquired according to time, temperature or detection result. For example, in the case where the outdoor ambient temperature is high, when it is detected that a user returns home, the full windless mode is turned on. Among them, the all-no-wind mode is the maximum capacity to dissipate the wind and then send it out to the air conditioner. It can be realized separately, without wind-induced wind deflector, louver and windless door. Taking the air deflector as an example, when all the upper air deflector and the lower air deflector are closed at the same time, the windless state is completely exhausted.

S20, obtaining a current room temperature and a preset temperature of the user, and calculating a difference between the room temperature and the preset temperature, which is recorded as a temperature difference value;

The current room temperature Th, the target temperature Ts set by the user, and the room temperature Th can be detected by the temperature sensor. Of course, it can also be obtained from other temperature detecting devices or household appliances. The target temperature Ts is the indoor temperature desired by the user. The temperature difference ΔT=Th-Ts.

S30, comparing the temperature difference and the preset temperature difference;

The preset temperature difference is a temperature difference set by the user or the researcher according to the temperature sensitivity of the human body. The temperature difference is 0.3 degrees Celsius to 0.7 degrees Celsius, and 0.5 degrees Celsius is taken as an example. The ΔT is compared with a preset temperature difference of 0.5 degrees Celsius.

S40, when the temperature difference is greater than the preset temperature difference, increasing the cold energy output of the air conditioner such that the temperature difference is less than or equal to the preset temperature difference;

When the temperature difference is greater than the preset temperature difference, it indicates that the current room temperature is different from the room temperature expected by the user, and the working state of the air conditioner component needs to be further adjusted to increase the output of the cold energy to continue to lower the indoor temperature. The working state of the air conditioner component includes the working frequency of the compressor, the rotational speed of the wind wheel, and the degree of opening of the air deflector, the louver or the windless door.

S50: When the temperature difference is less than or equal to the preset temperature difference, the current working state of the air conditioner is maintained.

When the temperature difference is less than or equal to the preset temperature difference, it indicates that the current room temperature is very close to the room temperature expected by the user, and the user's demand can be satisfied. At this time, only the current working state of the air conditioner needs to be maintained, and the user can be satisfied. Wind and room temperature requirements.

In this embodiment, first, the windless control command is received, and the windless air supply mode is entered; then, the current room temperature and the user preset temperature are obtained, and the difference between the room temperature and the preset temperature is calculated, and recorded as Temperature difference; then, comparing the temperature difference with the preset temperature difference; then, when the temperature difference is greater than the preset temperature difference, increasing the cold energy output of the air conditioner so that the temperature difference is less than or equal to the preset temperature difference; then, when the temperature difference is less than or When the temperature difference is equal to the preset temperature difference, the current working state of the air conditioner is maintained; by first applying the air conditioner to the windless air supply, when the difference between the indoor temperature and the preset temperature is large, the compressor frequency of the air conditioner needs to be adjusted. The speed of the wind wheel or the yaw angle of the air deflector increases the cold energy output of the air conditioner so that the indoor temperature can quickly meet the needs of the user.

The following mainly introduces how to adjust the working state of the air conditioner components step by step. In general, first increase the operating frequency of the compressor (in some embodiments, the speed of the wind turbine can be increased at a small rate at the same time to accelerate the cold energy. Dissipation) to increase the refrigeration capacity of the compressor and reduce the temperature of the heat exchanger; when increasing the compressor frequency (in some embodiments, while increasing the speed of the wind turbine at the same time) can not reduce the indoor temperature, the rapid and rapid Increase the speed of the wind wheel to further increase the air volume, thereby increasing the discharge of cold energy to further reduce the room temperature; when the speed of the wind wheel is raised to the preset maximum speed, the room temperature cannot be lowered to the preset temperature of the user, and the temperature is turned on. If the upper air deflector fails to meet the cooling demand, the upper air deflector will be fully opened; if the upper air deflector is fully opened, the cooling demand cannot be met. At this time, the partial lower air deflector is opened; if it still cannot meet the cooling If necessary, all open the lower air deflector. When the lower air deflector has been fully opened, but still can not meet the user's cooling demand, the user is sent a prompt message to let the user know the working state and temperature state of the air conditioner.

The step of increasing the cold energy output of the air conditioner such that the temperature difference is less than or equal to the preset temperature difference specifically includes:

Increase the operating frequency of the air conditioner compressor;

Increasing the operating frequency of the compressor to increase the energy output of the compressor, thereby reducing the temperature of the indoor heat exchanger, thereby increasing the temperature difference inside the air conditioner and the room, and accelerating the energy transfer into the room to quickly reduce the indoor temperature. In this embodiment, the adjustment of the compressor frequency is a rapid adjustment, that is, a rapid increase in the compressor frequency.

In some embodiments, in order to transfer cold energy to the room as quickly as possible, the rotational speed of the air conditioner indoor wind turbine is increased. During this process, the rotational speed of the rotor is slowly increased, in contrast to the rapidly increasing compressor frequency in the above embodiment, for the purpose of increasing cold energy transfer. The timing of increasing the speed of the rotor can be performed simultaneously with increasing the frequency of the compressor, or after the adjustment of the operating frequency with the compressor.

Detecting the wall temperature of the refrigerant pipe of the indoor heat exchanger;

After reducing the temperature of the indoor heat exchanger, it is necessary to judge whether the cold energy on the indoor heat exchanger is quickly radiated to the outside. At this time, it is necessary to detect the temperature of the indoor heat exchanger. There are many ways to detect the wall temperature T2 of the refrigerant pipe of the indoor heat exchanger, for example, by temperature sensor detection.

Comparing the tube wall temperature T2 and the preset tube temperature;

After detecting the temperature of the pipe wall, it is compared with the preset pipe temperature, wherein the preset pipe temperature is calculated by the user or calculated by the research and development personnel according to the energy transfer speed. The preset tube temperature ranges from 2 to 4 degrees Celsius, and 3 degrees Celsius is used as an example, that is, T2 and 3 degrees Celsius are used for comparison.

When the pipe wall temperature is less than or equal to the preset pipe temperature, increasing the cold energy output of the air conditioner to make the pipe wall temperature be greater than the preset pipe temperature;

When the wall temperature of the refrigerant pipe of the indoor heat exchanger is less than or equal to the preset pipe temperature, that is, T3≤3, indicating that the cold energy on the refrigerant pipe of the heat exchanger is not transmitted in time, resulting in a low wall temperature. At this time, the transfer speed of the cold energy should be increased as much as possible so that the temperature of the refrigerant pipe is greater than the preset pipe temperature.

When the wall temperature is greater than the preset tube temperature, the temperature difference is compared with the preset temperature difference.

When the wall temperature is greater than the preset pipe temperature, it indicates that the cold energy on the heat exchanger has been well transmitted to the room. At this time, the energy generated by the compressor is transmitted in time. At this time, the temperature difference value and the preset temperature may be compared, and if the temperature difference is less than or equal to the preset temperature ΔT ≤ 0.5, the current working state of the air conditioner is maintained.

In order to further increase the output of the capability, the step of increasing the cold energy output of the air conditioner such that the tube wall temperature is greater than the preset tube temperature comprises:

Adjusting the speed of the air conditioner indoor wind turbine to a preset maximum speed;

When the compressor frequency is increased and the wind turbine speed is slowly increased, and the pipe wall temperature is still less than or equal to the preset pipe temperature, the speed of the wind wheel is adjusted to a preset maximum speed. The preset maximum speed can be the maximum rated speed that the air conditioner can withstand, or the maximum speed that the user can set according to the actual situation. The maximum speed of the rotor is increased to deliver cold energy to the room as quickly as possible.

Detecting the wall temperature of the refrigerant pipe of the indoor heat exchanger; comparing the wall temperature and the preset pipe temperature;

After the wind wheel is raised to the maximum speed, the wall temperature of the refrigerant tube is again detected, and the tube wall problem and the preset tube temperature are compared. When the pipe wall temperature is less than or equal to the preset pipe temperature, the windless wind deflector is opened to increase the air outlet area. That is, when the pipe wall temperature is less than or equal to the preset pipe temperature, it indicates that the cold energy at this time is still not effectively transmitted, or the current air volume does not match the current compressor operating frequency, and cannot be cooled. Can be transported very well. At this time, the air volume can be increased by increasing the effective air outlet area.

The following describes how to increase the air supply volume by increasing the air outlet area. Among them, mainly by adjusting the opening ratio of the upper windless component to adjust the opening area of the air outlet. The windless component may be a windless wind deflector, a louver or a door body. In the following embodiments, a windless wind deflector will be described as an example.

The step of opening the windless wind deflector to increase the wind output area specifically includes:

Opening the windless wind deflector to open the upper air outlet to the first preset ratio to increase the air outlet area; detecting the wall temperature of the refrigerant tube of the indoor heat exchanger; comparing the wall temperature and the preset tube temperature When the pipe wall temperature is less than or equal to the preset pipe temperature, opening the windless wind deflector to open the upper air outlet to a second preset ratio to increase the wind output area, wherein the second pre- Set the ratio to be greater than the first preset ratio.

First open part of the upper air deflector to increase the air volume of the air conditioner. The first preset ratio opened is 30%~40%, that is, 30%~40% of the total area of the upper air outlet is opened, taking 35% as an example. There are a plurality of ways of opening the upper air deflector, which may be to continuously open a plurality of upper air deflectors, or to open a plurality of upper air deflectors at intervals, so as to evenly arrange the gaps formed by opening the upper air deflector. The upper part makes the air more uniform, and the air volume at each position of the upper air outlet is equivalent, so as to avoid excessive wind and wind at the upper air outlet. After the first preset proportion of the upper air deflector is turned on, the tube wall temperature is detected again. When the tube wall temperature is greater than the preset tube temperature, it indicates that the cold energy has been transmitted well, if the tube wall temperature is still less than or equal to the preset tube. At warm time, it indicates that the cold energy is still not transmitted to the room very well, and it is necessary to further increase the air outlet area. At this time, the proportion of the open upper air deflector is further increased, and the second preset ratio is opened to the second preset ratio. It is 60%~70%, taking 65% as an example to further increase the effective area of the upper air outlet. In the above embodiment, the upper air deflector is evenly spaced apart, so that the upper air outlet area of the second preset ratio is evenly distributed on the upper portion of the air conditioner cabinet to uniformly flow the airflow.

When the tube wall temperature is greater than the preset tube temperature, the cold energy transfer is better, and the temperature difference can be compared. Value and preset temperature difference. If the wall temperature is less than or equal to the preset pipe temperature, it indicates that the transmission of cold energy is still insufficient. At this time, all the upper air deflectors are opened, that is, 100% are all opened, so that all the upper air outlets are ventilated.

It should be noted that, in some embodiments, the rotational speed of the wind wheel increases as the total area of the air outlet (including the upper air outlet and the lower air outlet) increases, that is, the larger the total area of the open air outlet, the faster the speed of the wind wheel, In this way, the increase of the speed of the wind wheel and the increase of the area of the air outlet are organically combined. As for the relationship between the open air outlet area and the rotor speed, it can be adjusted according to a preset ratio, or can be in accordance with a curve relationship, and as the air outlet area increases, the speed of the wind wheel increases. The utilization rate of cold energy is effectively improved.

Value and preset temperature difference. If the wall temperature is less than or equal to the preset pipe temperature, the transmission of cold energy is still insufficient. At this time, the lower air deflector is opened to open the lower air outlet to a third preset ratio, and the third preset ratio is 30%~40%, taking 35% as an example. By opening part of the lower air deflector, the air outlet area of the air outlet is further increased, and the air volume is further increased, so that the cold energy can be quickly output.

When the wall temperature of the pipe is less than or equal to the preset pipe temperature, the step of opening the lower windless wind deflector to open the lower air outlet to the third preset ratio to increase the wind output area further includes: Detecting the wall temperature of the refrigerant pipe of the indoor heat exchanger; comparing the pipe wall temperature and the preset pipe temperature; when the pipe wall temperature is less than or equal to the preset pipe temperature, opening the windless wind deflector to make the upper The air outlet is opened to a fourth preset ratio to increase the air outlet area, wherein the fourth preset ratio is greater than the third preset ratio.

After the lower air outlet is opened to the third preset ratio, the tube wall temperature is detected again, and then the tube wall temperature and the preset tube temperature are compared. When the tube wall temperature is greater than the preset tube temperature, the cold energy transmission has been compared. Well, you can compare the temperature difference and the preset temperature difference. If the wall temperature is less than or equal to the preset pipe temperature, it indicates that the transmission of cold energy is still insufficient. At this time, it is necessary to continue to open the lower air deflector so that the lower air outlet opens to the fourth preset ratio, and the fourth preset ratio It is 60%~70%, taking 65% as an example. By increasing the area of the lower air deflector, the total air outlet area of the air outlet is further increased, and the air volume is further increased, so that the cold energy can be quickly output.

When the tube wall temperature is greater than the preset tube temperature, the cold energy transmission has been compared. Well, you can compare the temperature difference and the preset temperature difference. If the wall temperature is less than or equal to the preset pipe temperature, it indicates that the transmission of cold energy is still insufficient. At this time, it is necessary to continue to open the lower air deflector so that the lower air outlet is fully opened, that is, 100% all open.
