[0022] In conjunction with Figs. 1 to 9, according to an embodiment of the present invention,
an air conditioner is provided.
[0023] Specifically, as shown in Fig. 1, the air conditioner includes a housing 10. The
housing 101 has an upper air outlet 11 and a lower air outlet 12, wherein the upper
air outlet 11 has an air outlet capacity greater than an air outlet capacity of the
lower air outlet 12.
[0024] In the present embodiment, the air outlet capacity of the upper air outlet is set
to be greater than that of the lower air outlet, such that during the heating, the
air conditioner may realize an effect in which an air stream blown from the upper
air outlet suppresses an air stream blown from the lower air outlet, a floor covering
area of hot air can be an effectively enlarged and a blasting comfort of the air conditioner
can be enhanced.
[0025] Further, the housing 10 further has an air inlet 13 having an air inlet capacity
ϕ, and the upper air outlet 11 has an air outlet capacity ϕ1, wherein 53%ϕ≤ϕ≤1≤70%ϕ.
This arrangement can effectively improve the blasting comfort of the upper air outlet
11 of the air conditioner and enhance the user's operational experience.
[0026] Preferably, the lower air outlet 12 has an air outlet capacity ϕ2, wherein 30%ϕ≤ϕ2≤47%ϕ.
This arrangement can effectively improve the blasting comfort of the lower air outlet
12. In the present embodiment, ϕ1 + ϕ2 = ϕ. This arrangement can effectively improve
the heating performance of the air conditioner.
[0027] As shown in Fig. 2, the air inlet 13 has a lower edge at a distance L1 from ground,
wherein 0.3m≤L1≤0.5m. The air inlet 13 has a width W1, wherein 0.1m≤W1≤0.4m. This
arrangement can effectively improve the air intake efficiency of an entirety of the
air conditioner.
[0028] In order to further improve the blasting comfort of the air conditioner, the air
conditioner further includes a temperature sensing means and an opening-and-closing
member. The temperature sensing means is connected to the housing 10, wherein the
temperature sensing means is configured to monitor an indoor temperature. The opening-and-closing
member is disposed at the lower air outlet 12, and configured to close the lower air
outlet 12 when the indoor temperature monitored by the temperature sensing means reaches
a preset value.
[0029] As shown in Fig. 1, the upper air outlet 11 has a lower edge at a distance L2 from
ground, wherein 1.6m≤L2≤1.9m. The lower air outlet 12 has a lower edge at a distance
L3 from the ground, wherein 0 < L3≤0.2m. This arrangement can effectively control
an air outlet capacity of the upper air outlet 11 and the lower air outlet 12. The
air blown by the air conditioner is more comfortable by changing the distance between
the air inlet of the air conditioner and the ground, and/or between the air outlet
of the air conditioner and the ground.
[0030] In order to further improve the blasting comfort of the air conditioner, the upper
air outlet 11 and the lower air outlet 12 are sequentially arranged along a vertical
axis direction of the housing 10, and the upper air outlet 11 and the lower air outlet
12 are located on the same side of the housing 10. The lower air outlet 12 is symmetrically
arranged with respect to an extension line of a geometric centerline of the upper
air outlet 11 extending along a vertical direction. The arrangement enables that the
air stream blown from the upper air outlet 11 and the air stream blown from the lower
air outlet 12 mix with each other to effectively avoid laminarity of the indoor streams,
and effectively improve the comfort of the air conditioner during cooling and heating.
[0031] Further, in the present embodiment, the air conditioner has a cooling mode and a
heating mode, wherein ADPI > 83% when the air conditioner is in the cooling mode or
the heating mode. Specifically, as shown in Figs. 3, 8 and 9, the housing 10 may have
a circular, elliptical or quadrate cross-section. The quadrate may be square or rectangular.
[0032] Specifically, the air conditioner is used to effectively solve the problem of poor
heating comfort and indoor thermal stratification of the current household air conditioners
and solves the problem that the current household air conditioners are difficult to
take into consideration the refrigeration and the heating comfort at the same time.
The air conditioner of this structure is used to significantly shorten the processing
time for the indoor air to meet the comfort requirements and save the operational
cost. The power consumption may be saved by 48% as compared to the conventional household
air conditioners, the air conditioner can quickly achieve thermal balance.
[0033] The heights of the upper and lower air outlets relative to the ground and the distance
between the air outlets are both optimally designed, so that the airflow organization
within the room is reasonable and efficient. At the same time, the optimal design
of air capacity ratio of the upper air outlet and lower air outlet is used, to achieve
an airflow control effect by configuring different air capacity proportions of the
upper air outlet and the lower air outlet. During the heating, it is possible to implement
that the upper air outlet suppresses the air stream of the lower air outlet, thereby
increasing the floor covering area of hot air and significantly enhancing the heating
comfort. During the cooling, the upper and lower air outlets perform blasting at the
same time, and after the indoor temperature reaches a preset temperature rapidly,
it is allowable to change to separately blast from the upper air outlet, thereby avoiding
a blasting feeling to be produced.
[0034] By optimizing the design of the size of the air inlet, the airflow organization and
circulation efficiency is ensured while the windward area of the heat exchanger is
satisfied.
[0035] As shown in Figs. 1 to 3, in a top view, the housing of the air conditioner has a
circular cross-section with a diameter D1. The housing has two air outlets and one
air inlet, which are an upper air outlet, a lower air outlet, and an air inlet respectively,
and all symmetrical with respect to a centerline of the housing. Under the heating
condition, the blasting manner of the air conditioner is as shown in Fig. 4. The upper
air outlet and the lower air outlet perform blasting at the same time, and the air
capacity of the upper air outlet has a proportion ϕ1 (that is, the percentage of the
air outlet capacity of the upper air outlet relative to the air inlet capacity of
the air inlet), and the air capacity of the lower air outlet has a proportion ϕ2,
wherein ϕ1>ϕ2. The lower air outlet is disposed proximate to the ground. Due to the
viscosity of the air, the produced air stream is conveyed close to the ground to realize
a carpet-type blasting. The air stream produced by the upper air outlet performs downward
suppression to increase a movement distance of the air stream on the ground, such
that there is a greater blasting area during the heating, thereby avoiding a thermal
stratification phenomenon in a room, and significantly improving the heating comfort.
Under the cooling condition, the blasting mode at an extremity is as shown in Figs.
5 and 6. The air capacity of the upper air outlet has a proportion ϕ1, and the air
capacity of the lower air outlet has a proportion ϕ2, wherein ϕ1>ϕ2. In order to rapidly
reach a set temperature and avoid a blasting feeling to be produced, the upper air
outlet blasts obliquely upwards, such that cold air which has a large density falls
slowly from up to down, to effectuate a shower-type blasting. The lower air outlet
performs blasting close to the ground, to effectuate rapid temperature reduction in
a near-ground area. When the temperature in a room is close to a set temperature,
the lower air outlet is closed, such that only a shower-type blasting manner is used,
to ensure the indoor comfort. In addition to the above-described blasting manner,
personalized blasting may also be performed at the extremity according the needs of
human body. As shown in Fig. 7, the upper air outlet may swing longitudinally within
a certain angle β, and the upper air outlet and the lower air outlet may swing right
and left within a certain angle, to satisfy different blasting requirements.
[0036] By using the air conditioner of the present application, it is possible to ensure
reasonable and comfortable airflow organization, and the indoor Air Diffusion Performance
Indices (ADPIs) can reach more than 83% under both the cooling and heating conditions.
The definition of ADPI is as follows:
[0037] ADPI is an airflow organization assessment standard recommended by AMERICAN SOCIETY
OF HEATING, REFRIGERATING AND AIR-CONDITIONING ENGINEERS (ASHRAE), in which by considering
a temperature and speed of each measurement point, it is considered that when an effective
draft temperature (EDT) of a certain point satisfies the range between -1.7 and 1.1
°C, a majority of people feel comfortable. The percentage occupied by such points
in all the measurement points is an ADPI value. When ADPI ≥ 80%, the airflow organization
within the air-conditioned area may be considered satisfactory. The calculation formula
is as follows:
ADPI = (-1.7 < ΔET < 1.1) / total number of measurement points × 100%.
[0038] In the formula, ΔET is an effective blasting temperature, ti is a temperature of
a certain point in a working area with a unit of °C, t
n is a given indoor average temperature with a unit of °C, and u
i is an air flow rate at a certain point in a working area with a unit of m/s. The
ADPI value comprehensively reflects an impact by an airflow organization in the air-conditioned
area. The higher the ADPI value is, the more people feel satisfactory with the environment
among the people who stay within the air-conditioned area. When ADPI ≥ 80%, it may
be considered that the airflow organization blown by the air conditioner is satisfactory.
