Referring to Figures 1 through 9, in accordance with an embodiment of the present invention, an air conditioner is provided.

Specifically, as shown in FIG. 1, the air conditioner includes a housing 10. The casing 10 has an upper air outlet 11 and a lower air outlet 12, wherein the air outlet of the upper air outlet 11 is larger than the air volume of the lower air outlet 12.

In this embodiment, the air outlet amount of the upper air outlet is set to be larger than the air outlet amount of the lower air outlet, so that the airflow blown from the upper air outlet can suppress the airflow blown from the lower air outlet when the air conditioner is heating. The function can effectively increase the area where the hot air falls, and increase the comfort of the air conditioner.

Further, the housing 10 further has an air inlet 13 , and the air inlet 13 has an air intake amount of

The air volume of the upper air outlet 11 is

among them,

This arrangement can effectively improve the comfort of the air outlet of the air conditioner 11 and increase the user experience.

Preferably, the amount of air blown from the lower air outlet 12 is

among them,

This arrangement can effectively improve the comfort of the air outlet of the lower air outlet 12. In this embodiment,

This arrangement can effectively improve the heating performance of the air conditioner.

As shown in Fig. 2, the distance between the lower edge of the air inlet 13 and the ground is L1, wherein 0.3m ≤ L1 ≤ 0.5m. The width of the air inlet 13 is W1, wherein 0.1 m ≤ W1 ≤ 0.4 m. This setting can effectively improve the air intake efficiency of the air conditioner.

In order to further improve the airflow comfort of the air conditioner, the air conditioner further includes a temperature sensing device and an opening and closing member. The temperature sensing device is connected to the housing 10, and the temperature sensing device is used to monitor the temperature in the room. The opening and closing member is disposed at the lower air outlet 12, and when the temperature of the indoor monitored by the temperature sensing device reaches a preset value, the opening and closing member closes the lower air outlet 12.

As shown in Fig. 1, the distance between the lower edge of the upper air outlet 11 and the ground is L2, wherein 1.6m ≤ L2 ≤ 1.9m. The distance between the lower edge of the lower air outlet 12 and the ground is L3, where 0 < L3 ≤ 0.2 m. In this way, the amount of air blown from the upper air outlet 11 and the lower air outlet 12 can be effectively controlled, and the air blown by the air conditioner can be made more comfortable by changing the distance between the air inlet and the air outlet of the air conditioner and the ground.

In order to further improve the airflow comfort of the air conditioner, the upper air outlet 11 and the lower air outlet 12 are sequentially disposed along the vertical axis direction of the casing 10, and the upper air outlet 11 and the lower air outlet 12 are opened on the same side of the casing 10. The lower air outlet 12 is symmetrically disposed with respect to an extension line of the geometric center line of the upper air outlet 11 extending in the vertical direction. The arrangement is such that the airflow blown from the upper air outlet 11 and the airflow blown from the lower air outlet 12 can effectively avoid the stratification of the indoor airflow, thereby effectively improving the comfort of the air conditioner during cooling and heating. .

Further, in the embodiment, the air conditioner includes a cooling mode and a heating mode, and when the air conditioner is in the cooling mode or the heating mode, ADPI>83%. Specifically, as shown in FIGS. 3, 8, and 9, the cross section of the casing 10 may be provided in a circular, elliptical or square configuration. Among them, the square can be square or rectangular.

Specifically, the air conditioner effectively solves the problem that the current household air conditioner has poor heating comfort and indoor temperature stratification, and solves the problem that the current household air conditioner has difficulty in both cooling and heating comfort. The air conditioner adopting the structure can greatly shorten the processing time for the indoor air to meet the comfort requirement, and save the use cost. Since the power consumption of the conventional household air conditioner is 48%, the air conditioner can quickly achieve the heat balance.

The upper and lower outlets are optimized from the ground height and the distance between the tuyères, so that the airflow in the room is reasonable and efficient. At the same time, the optimal air volume ratio design of the upper and lower air outlets is adopted, and the air flow control effect is achieved by setting the different air volume ratios of the upper air outlet and the lower air outlet, and the upper air outlet can suppress the air flow of the lower air outlet when heating. Increase the hot air floor area and greatly improve the heating comfort. When cooling, the upper and lower air outlets simultaneously emit air, and after the indoor temperature reaches the set temperature quickly, the air outlet can be separately driven out to avoid the feeling of blowing.

By optimizing the size of the air inlet, the airflow tissue circulation efficiency is ensured while satisfying the windward area of the heat exchanger.

As shown in FIG. 1 to FIG. 3, the housing of the air conditioner has a circular cross section with a diameter D1. The housing has two air outlets and an air inlet, respectively, an upper air outlet, a lower air outlet, and an air inlet. Both are symmetric about the centerline of the housing. Under the heating condition, the air supply mode of the air conditioner is as shown in Fig. 4. The upper and lower air outlets simultaneously emit air, and the air volume of the upper air outlet is

(ie, the amount of air output from the upper air outlet accounts for the percentage of the air intake at the air inlet), and the air volume at the lower air outlet is

The lower air outlet is close to the ground. Due to the viscosity of the gas, the generated airflow is closely attached to the ground to realize the carpet air supply. The airflow generated by the upper air outlet is pressed downward, increasing the airflow distance on the ground, and making the heating air supply area more. Large, to avoid temperature stratification in the room, greatly improving heating comfort. In the cooling condition, the end air supply mode is as shown in Fig. 5 and Fig. 6, and the air volume of the upper air outlet is

The proportion of the air outlet at the outlet is

In order to quickly reach the set temperature and avoid the feeling of blowing, the upper air outlet is blown upwards obliquely, the density of the cold air is large, and the air is slowly lowered from above, so that the shower air is blown, and the air outlet is close to the ground to provide air, and the near ground area is fast. Cooling down, when the room temperature is close to the set temperature, the downwind is closed, and only the shower air supply mode is adopted to ensure indoor comfort. In addition to the above air supply mode, the end can also be personalized according to the needs of the human body, as shown in Fig. 7, the upper air outlet can swing up and down within a certain angle β, and the upper and lower air outlets can be fixed. Sweep the wind from side to side to meet different air supply requirements.

The air conditioner of the present application can ensure reasonable airflow organization, and the Air Diffusion Performance Index (ADPI) can reach more than 83% under refrigeration and heating conditions. The definition of ADPI is as follows:

ADPI is the airflow organization evaluation standard recommended by American HVAC Association ASHRAE. It considers the temperature and speed of each measuring point. It is considered that the effective draft temperature (EDT) at a certain point satisfies between -1.7 and 1.1 °C. Some people feel comfortable. The percentage of such points in all test points is the ADPI value. When ADPI ≥ 80%, the airflow organization in the air-conditioned area can be considered satisfactory. The calculation formula is as follows:

ΔET=(t _i -t _n )-7.66(u _i -0.15);

Where ΔET is the effective blowing temperature, t _i is the temperature of a certain point in the working area, the unit is °C, t _n is the given indoor average temperature, the unit is °C, u _i is the air flow rate at a certain point in the working area, the unit is m /s. The ADPI value fully reflects the impact of airflow organization in the air-conditioned area. The higher the ADPI value, the more people who are satisfied with the environment in the air-conditioned area. When ADPI ≥ 80%, it can be considered that the airflow structure blown by the air conditioner is satisfactory.
