Abstract: An air duct component includes first and second volute members arranged oppositely in a cross section perpendicular to an axis of a cross-flow impeller. An inner end of the first volute member includes a volute tongue. A cross-flow air duct formed between the first and second volute members includes a middle air duct section and an end air duct section arranged along an axial direction of the cross-flow impeller. The middle air duct section includes a middle air outlet duct located downstream of a vertical line that passes through the volute tongue and is perpendicular to the second volute member. The end air duct section includes an end air outlet duct located downstream of the vertical line. A cross-sectional area of the middle air outlet duct is larger than a cross-sectional area of the end air outlet duct.

Abstract: An air conditioner indoor unit includes a housing, a chassis, and an air duct assembly. The housing includes a face frame including an inner cavity having an opening. The chassis covers a side of the face frame. The air duct assembly includes a mounting bracket movably mounted at the chassis and detachably connected with the face frame. The mounting bracket is configured to move into or out of the inner cavity through the opening of the inner cavity along an insertion direction.

Abstract: An indoor unit includes a housing, an air duct member, and a thermal insulation tube. The housing has an accommodating cavity. the air duct member is detachably mounted in the accommodating cavity. A mounting space is formed at a side of the air duct member in a length direction of the air duct member. The mounting space has a mounting opening facing an outside of the housing. The thermal insulation tube includes a tube section extending along a direction perpendicular to the length direction of the air duct member. The tube section is at least partially arranged in the mounting space.

Abstract: An air conditioner includes an air conditioner body including a cross-flow air duct and an air outlet in communication with the cross-flow air duct, a cross-flow impeller arranged at the cross-flow air duct and located upstream of the air outlet, and an air guide assembly including an air guide member rotatable around a pivot axis at the air outlet. The air conditioner body includes a first volute and a second volute arranged opposite to each other in a cross section perpendicular to a rotation axis of the cross-flow impeller. The cross-flow air duct is located between the first volute and the second volute. A set air duct is formed between the air guide member and the first volute when an air output volume of the air conditioner is maximum. A width of the set air duct in the cross section first increases and then decreases along an air output direction.

Abstract: A system and method for controlling communications between a plurality of clients and a central component. An embodiment of the invention includes one or more buses that connect the clients and the central component. This embodiment also includes a control module that is configured to receive ASK messages from the clients and issue GO commands to the clients. Each ASK message represents a request from a client to access the central component. Each GO command to the client represents permission for that client to access the central component. The control module comprises delay stages that delay the GO command. The delays may be different from client to client. The number of delay stages is chosen so that for all clients, the delay between the issuance of a GO command and the receipt at the central component of communications from the clients is the same.

Abstract: A database system is able to represent spatial data with regions in a defined space, such as a z-ordered space. Instead of, or in addition to, a descending decomposition technique (e.g., a top-down decomposition technique) to represent the spatial data with the z-ordered space, the database system is able to use an ascending decomposition technique (e.g., a bottom-up decomposition technique).
