AIR-CONDITIONER AIR SUPPLY APPARATUS IN VERTICAL AIR-CONDITIONER

摘要

An air-conditioner air supply apparatus (1) in a vertical air-conditioner comprises at least three annular air guiding bodies (11, 13, 17, 12) which run through in the middle and have front openings and rear openings. Each annular air guiding body (11, 13, 17, 12) is a single component. A back opening of the annular air guiding body (11, 13, 17, 12) is an air inlet, and a front opening is an air outlet. Multiple annular air guiding bodies (11, 13, 17, 12) are arranged sequentially from front to back, and a through air duct running through from front to back is formed in the middle. An annular heat-exchange air duct (14, 15, 18) is formed between adjacent two annular air guiding bodies (11, 13, 17, 12). An air inlet of a rear-end annular air guiding body (12) located at the rear is a non-heat-exchange air inlet (122), and an air outlet of a front-end annular air guiding body (11) located in the front is a mixed air outlet (111). Volumes of the multiple annular heat-exchange air ducts (14, 15, 18) are gradually reduced in a direction from the non-heat-exchange air inlet (122) to the mixed air outlet (111). By using the air supply apparatus (1) in the air-conditioner, an amount of inlet air of the air-conditioner can be increased, the softness of outlet air of the air-conditioner can be improved, which helps to uniformly exhaust peripheral air from the heat-exchange air ducts (14, 15, 18); and pressure loss and noise can be reduced.
