High-speed air-out narrow-facade air conditioner outdoor unit

Abstract

The invention discloses a high-speed air-out narrow-facade air conditioner outdoor unit. The high-speed air-out narrow-facade air conditioner outdoor unit comprises a shell, the front face of the shell is a narrow facade, the two side faces, adjacent to the narrow facade, of the shell are wide facades; at least one group of outer heat exchange modules are arranged in the shell, each outer heat exchange module comprises a centrifugal fan and at least one outer heat exchanger, and the outer heat exchangers are used for being connected with an air conditioner inner heat exchanger to form a circulation channel for refrigerant circulation; an air inlet part communicating with the outside of the shell is arranged on the narrow vertical surface and / or the wide vertical surface corresponding to each external heat exchanger; a partition plate is further arranged in the shell, and a closed heat exchange cavity is defined by the outer heat exchanger, the partition plate and / or the inner wall of the shell; an air inlet of a centrifugal fan communicates with the heat exchange cavity, and an air outlet of the centrifugal fan communicates with an air outlet part arranged on the narrow vertical face of the shell; under the action of the centrifugal fan, outside air enters the shell from the air inlet part on the front face and / or the side face, then flows through the outer heat exchanger for heat exchange, enters the heat exchange cavity and is exhausted from the front face of the shell through the centrifugal fan and the air outlet part.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner external unit with a high-speed air outlet and a narrow facade. Background technique [0002] Household central air conditioners, including small multi-connected fluorine machines and two-connected and triple-connected water machines, because there is only one outdoor host, and one outdoor host drives multiple indoor units through the fluorine circuit or water channel, which has a beautiful facade and a The on-site installation workload is small, the maintenance of the external unit is simple, and the functions of fresh air, floor heating and sanitary hot water can be expanded. It is favored by real estate developers and owners. It is replacing the traditional split room air conditioner and is rapidly gaining popularity in the household air conditioner market. rise. [0003] In recent years, during the rapid rise of household central air conditioners,...
