Self-oscillation jet-type mixing-increasing heat exchange air outlet device

Abstract

The invention belongs to the technical field of air conditioning equipment mixing-increasing heat exchange, in particular to a self-oscillation jet-type mixing-increasing heat exchange air outlet device, and aims to solve the problems of fixed air outlet, poor heat exchange capability, non-uniform space temperature distribution, poor personnel comfort and the like in air outlet devices of most existing large-sized central air conditioners. The self-oscillation jet-type mixing-increasing heat exchange air outlet device comprises a main cavity and an odd number of feedback channels which are distributed on the main cavity at equal intervals, wherein the main cavity comprises a main chamber; and an air inlet and an air outlet are formed in two opposite ends of the main chamber respectively, and are in communication with each other through the main chamber. Through adoption of the mixing-increasing heat exchange air outlet device disclosed by the invention, the indoor temperature distribution uniformity is improved, and the comfort of the household living environment is improved greatly. The indoor temperature distribution is more uniform; frequent switching-on / off actions and refrigerating / heating processes of central air conditioning equipment are avoided; and the service life of the air conditioning equipment is prolonged while the running cost of the air conditioner is loweredand the electric energy is saved.

Description

technical field [0001] The invention belongs to the technical field of mixed heat exchange for air-conditioning equipment, in particular to a self-excited oscillating jet type increased mixed heat exchange air outlet device. Background technique [0002] Air-conditioning equipment is widely used in heating, cooling, etc. With the gradual improvement of the public's requirements for the comfort of production and living environments, air-conditioning equipment appears in all aspects of social production and life. For occasions such as large shopping malls, office buildings, airports, stations, and factory buildings, central air conditioners are considered to be the main equipment for temperature regulation and temperature control. However, at present, the air outlets of many central air conditioners cannot automatically adjust the wind direction, and need to manually adjust the air outlet device. Although some existing high-end air outlet devices can electrically adjust the a...
