Description

TECHNICAL FIELD

[0001] The utility model belongs to air conditioner technical field, concretely relates to a top-mounted embedded air conditioner indoor unit. BACKGROUND

[0002] The top-mounted embedded air conditioner indoor unit, also known as a ceiling air conditioner, a ceiling machine or a ceiling-mounted air conditioner, is an air conditioning system installed on the indoor ceiling. The top-mounted embedded air conditioner indoor unit distributes cold or hot air evenly to the entire space through pipes and equipment hidden in the ceiling, thereby achieving the purpose of adjusting the indoor temperature.

[0003] The advantages of the top-mounted embedded air conditioner are as follows:

[0004] (1) Space-saving: installed in the ceiling, it does not occupy the ground and wall space, making the indoor space more open;

[0005] (2) Elegant: due to its embedded design, it does not damage the overall aesthetics of the indoor decoration, and is suitable for various decoration styles;

[0006] (3) Uniform air supply: usually designed with multi-faceted air outlets, so that cold or hot air can be evenly distributed throughout the room, providing a comfortable temperature environment;

[0007] (4) Quiet design: usually has complete quiet design, with low operating noise, which does not affect the indoor environment;

[0008] (5) Multi-function: often has electric heating function, suitable for use in various climate conditions.
