Ceiling type air conditioner indoor unit

Abstract

The invention discloses a ceiling type air conditioner indoor unit. The ceiling type air conditioner indoor unit comprises an indoor unit shell used for being mounted on a ceiling (1), an inner circulation fan blade (6) located in the indoor unit shell and a drive device (4) for driving the inner circulation fan blade (6) to rotate. An air inlet (8) is formed in a panel (9) of the indoor unit shell. Air outlets (7) are formed in side plates (2) of the indoor unit shell. According to the ceiling type air conditioner indoor unit, linear losses generated by the fact that airflow turns in the indoor unit shell and flows out of the panel are reduced; and the short-circuit probability of the airflow is reduced, and the heat exchange effect is enhanced. Natural convection of air in a room is achieved, room surrounding type air supply free of air feeling is achieved, the situation that cold air directly blows to the human body is avoided, and the refrigeration effect and the use comfort in a refrigeration state are improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a ceiling-mounted air conditioner indoor unit. Background technique [0002] Ceiling-type air conditioner indoor units are widely used in homes and offices. [0003] Such as figure 1 and figure 2 As shown, in the current ceiling-mounted air-conditioning indoor unit, the air outlet 7 and the air inlet 8 are all arranged on the panel of the indoor unit housing, and the indoor unit housing is installed on the ceiling 1, and the air outlet near the indoor unit housing The panel 9 is provided with a ceiling partition 3 . The interior of the indoor unit housing is provided with an internal circulation vane 6 and a driving device 4 for driving the interior circulation vane 6 to rotate. The interior unit housing has an air outlet formed by its side wall 2 and a partition connected to the bottom of the heat exchanger 5. aisle. During the temperature adjustment proces...

Problems solved by technology

[0004] However, the high-speed radial airflow that passes through the internal circulation fan blades needs to turn and flow along the air outlet channel. The turning angle of the airflow is about 90°, and the turning angle is relatively large, which causes more losses along the way.

Moreover, the air outlet and the air inlet are both arranged on the panel, and the distance between them is small, so it is very easy for the airflow entering the indoor unit casing to exchange heat with the airflow flowing out of the indoor unit casing, forming an airflow short circuit. Affect the heat transfer effect

Moreover, in the cooling state, the cold air directly flows downward (towards the ground) from the air outlet 7, causing the cold air to blow directly on the human body, which affects the cooling effect and reduces the comfort of use in the cooling state
