- the first air outlet could deflect the airflow horizontally or downwardly, and the second air outlet could deflect airflow horizontally or upwardly, so that the air conditioner outputs airflow of upper and lower encircling air-out to achieve rapid cooling of the surrounding environment, making the current hot environment transit to a comfortable environment quickly.
- FIG. 4 shows a temperature cloud diagram when the ambient air temperature is about to reach a comfortable temperature, in the case that the first air outlet and the second air outlet simultaneously output airflow corresponding to the distribution patterns.
- FIG. 5 shows a temperature cloud diagram when the ambient air temperature is about to reach a comfortable temperature in the case that the air conditioner adopts one air outlet for frontal air-out.

- FIG. 8 shows a temperature cloud diagram of the environment in the case that one air outlet is still used for frontal air-out when the ambient temperature of the air conditioner reaches a comfortable temperature in the related art.
- the overall ambient temperature could be effectively controlled and the blowing feeling of the human body in the spatial range of the air conditioner could be reduced by controlling the first air outlet to output airflow corresponding to the distribution pattern and controlling the second air outlet to be closed according to the one or more third subparameters when the ambient temperature reaches the comfortable temperature, thereby enhancing the comfort level of the human body.
- the at least two air outlets comprise a first air outlet and a second air outlet, wherein the first air outlet is disposed to be higher than the second air outlet
- the second determining unit comprises: a third determining module configured to determine one or more fourth control subparameters used for controlling the first air outlet to deflect airflow downwardly to output airflow corresponding to a distribution pattern and controlling the second air outlet to output airflow corresponding a distribution pattern; a second detection module configured to detect the current ambient temperature of the environment where the air conditioner is located; and a fourth determining module configured to determine one or more fifth control subparameters used for controlling the first air outlet to output airflow corresponding to a distribution pattern and controlling the second air outlet to output airflow corresponding to a distribution pattern if the current ambient temperature is greater than a second preset temperature.
- the air conditioner may also comprise more than two air outlets, which are disposed at different heights to achieve staggered arrangement of the air outlets of the air conditioner.
- the first air outlet is controlled to deflect air downwardly to output airflow corresponding to a distribution pattern and the second air outlet is controlled to output airflow corresponding to a distribution pattern according to the one or more third control subparameters.
- the second air outlet deflects hot air towards the lower area of the environment to heat the space where the human feet are located; the first air outlet deflects hot air downwardly to heat the space where the body of the human body is located.
- the airflow output by the air conditioner is concentrated in the lower area and a space where the trunk area of the human body is located. Due to such airflow distribution patterns, the surrounding environment has a small temperature gradient and the ambient temperature distribution has good temperature uniformity; at the same time, the airflow output by the air conditioner in the heating mode is the hot airflow, so the ascent of the hot airflow in the lower area is favorable for effectively heating the environment in the spatial range of the air conditioner.
- the air conditioner could also detect the current ambient temperature, and the ambient condition of the air conditioner is determined by determining the sizes of the current ambient temperature and a second preset temperature.
- the second preset temperature may be a preset temperature threshold that makes people feel comfortable.
- the ambient temperature is less than the second preset temperature
- the human body feels cold, and the surrounding environment is in a cold ambient condition, thus airflow corresponding to one or more distribution patterns output by the air conditioner are kept unchanged to heat the surrounding environment.
- the ambient temperature is greater than the second preset temperature
- the human body does not feel cold, and the surrounding environment is in a comfort ambient condition.
- the first air outlet is controlled to output airflow corresponding to a distribution pattern
- the second air outlet is controlled to output airflow corresponding to a distribution pattern simultaneously according to one or more fifth control subparameters, as shown in FIG. 10 .
- the airflow output by the air conditioner is no longer concentrated in the trunk area space of the human body, thereby preventing high-temperature hot air from directly impacting the body and head areas of people or from being excessively conveyed to a space at such a height to cause discomfort of the human body after the ambient temperature reaches a comfortable temperature.
- the air conditioner since the air conditioner has heated the environment for a period of time, the hot air in the surrounding environment is mainly concentrated on the top of the environment.
- the hot air at the top of the environment could be promoted to circulate downward to other areas.
- the temperature of the airflow output by the first air outlet could be reduced, and the intensity of the airflow output by the first air outlet could be enhanced, thereby accelerating the circulation of heat in the surrounding environment and achieving energy-conservation operation function of the air conditioner.
- FIG. 11 shows the comparison of the relevant indicators when different air-deflecting airflow distribution patterns are used after the air conditioner performs heating operation for 3 hours, wherein centrifugal layered air-out is the air-deflecting airflow distribution pattern used in some embodiments of the present invention.
- the average ambient temperature reaches and stabilizes at about 20°C, and the vertical air temperature difference between a plane being 2.1m high and a plane being 0.1m high is 2.26°C, which is smaller than the vertical air temperature differences between the corresponding planes when other airflow distribution patterns are used;
- the ambient average temperature uniformity is 1.24°C, which is 2.12°C -2.51°C lower than those when other airflow distribution patterns are used, wherein the temperature uniformity is improved by 63%-74%; and the temperature rise rate of the area lower than 1.1 meters is 0.6°C/min in the first 30 minutes, which is 20%-50% higher than those when other airflow distribution patterns are used.
- the power consumption is the lowest, thus energy conservation of the air conditioner is achieved.
- the one or more airflow distribution patterns of some embodiments of the present invention when the air conditioner performs heating operation, the heat distribution in each area of the environment is uniform and the heat utilization efficiency in the environment is higher. But in the case that other airflow distribution patterns are used, the heat distribution in the environment is mostly concentrated in the upper area and the ambient heat distribution is not uniform, thus the heat utilization efficiency is low.
- an air conditioner comprising the followings.
- a sensor is configured to determine a current operating mode of the air conditioner.
- the operating mode of the air conditioner may comprise a heating mode and a cooling mode.
- the air conditioner raises the ambient temperature by outputting hot air to the surrounding environment; and when the current operating mode of the air conditioner is the cooling mode, the air conditioner reduces the ambient temperature by outputting cold air to the surrounding environment.
- a processor is configured to determine, in the current operating mode, one or more control parameters for controlling at least two air outlets of the air conditioner according to the current ambient temperature and generate a control instruction.
- the air conditioner may comprise two or more air outlets, all of which may output airflow to the surrounding environment so as to change the ambient temperature.
