Embodiment Construction

[0044] The ceiling-mounted air conditioner indoor unit of the present invention and the air conditioner outdoor unit (not shown) together constitute a vapor compression refrigeration cycle system to realize cooling / heating of the indoor environment.

[0045] Such as figure 1 , figure 2 , Figure 13 with Figure 14 As shown, the indoor unit of the ceiling type air conditioner of the present invention may generally include a housing 100 , a heat exchanger 400 and a laminar fan 300 . The ceiling-mounted air-conditioning indoor unit is integrally hoisted under the indoor roof, and the top of the casing 100 is used to connect with the roof. At least one air inlet 110 and at least one air outlet 120 are opened on the side of the casing 100 . The height positions of the air inlet 110 and the air outlet 120 on the side of the casing 100 are different, and the air outlet 120 is located above or below the air inlet 110 . That is, the ceiling-mounted air-conditioning indoor unit of...

Abstract

The invention provides a ceiling-type air conditioner indoor unit. The ceiling-type air conditioner indoor unit comprises a shell, a laminar flow fan and a heat exchanger; the side face of the shell is provided with one or more air inlets and one or more air outlets, and the one or more air outlets are located above or below the one or more air inlets; the rotating axis of the laminar flow fan isarranged in the shell in a vertically expanding mode, the side circumferential face of the laminar flow fan is opposite to the air outlets, when the laminar flow fan operates, air is sucked from one axial end of the laminar flow fan, and laminar flow air is generated through the viscous effect of the air and outwards blown in the radial direction of the laminar flow fan; the heat exchanger surrounds the laminar flow fan in the radial outer side of the laminar flow fan; and when the laminar flow fan operates, the indoor air is promoted to enter the shell from the air inlets, then sucked, then blown to the heat exchanger to be subjected to heat exchange, and finally blown back into the indoor space through the air outlets. The ceiling-type air conditioner indoor unit achieves multi-directional and large-range air supply, air supply noise is lowered, and the noise quality is enhanced.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a ceiling-mounted air conditioner indoor unit. Background technique [0002] Existing indoor units of air conditioners basically use cross-flow fans, and the air outlet direction is the front. Although there are air deflectors to guide the flow left and right, and swing leaves to guide the flow up and down, but due to the structure of the volute, the left and right air supply angle is usually less than 80° , The upper and lower air supply angles are usually less than 100°. It can be seen that the existing indoor units have fewer air supply directions, and the air supply range is very limited. [0003] Moreover, the current cross-flow fan mainly has forward blades, and the blades periodically impact the passing air flow, resulting in obvious rotating noise. The volute cooperates with the fan to achieve the air supply effect, and the front and rear volute tongues will al...
