Air outlet for precise control of air supply direction and method for realizing different airflow organization

Abstract

The invention discloses an air feeding port with the air feeding direction accurately-controlling function and a method for achieving different air flow structures of the air feeding port. The air feeding port structurally comprises an outer frame and multiple rows of horizontally-arranged first-level blades and multiple rows of vertically-arranged second-level blades are arranged in the outer frame; the two ends of each blade are rotationally connected with the outer frame; rotary shafts of the second-level blades are located on the same plane; the multiple rows of horizontally-arranged first-level blades are connected through a vertically connecting rod to form a set of first-level louvers and the multiple rows of vertically-arranged second-level blades are connected through horizontal connecting rods of the second-level blades respectively to form two sets of second-level louvers which are independent of each other; the first-level louvers and the second-level louvers are sequentially arranged in the air flow direction of the air feeding port; and an installation flange is arranged on the front face of the outer frame, the surface of the installation flange is provided with three scales respectively, and the scales are used for indicating the rotation angles of the first-level louvers and the second-level louvers. The air feeding port can be used in various sealed spaces, the optimal air flow structure manner can be created, and personnel can freely adjust the air feeding direction and the air flow.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air supply outlet for air volume distribution in a closed space where the air supply direction of an air conditioning system can be precisely controlled. Background technique [0002] With the continuous advancement of technology, air-conditioning systems are widely used in civil buildings and industrial plants. The thermal comfort of personnel and the needs of industrial manufacturing. The form of the air supply outlet at the end of the air conditioning system is an important factor affecting the airflow organization. At present, the commonly used forms of air supply outlets are louver air outlets, grille air outlets, diffusers and orifice air supply outlets, etc. According to the characteristics and requirements of space objects and reasonable selection of air outlet forms and installation positions, the required air flow organization form can be realized. However...

Problems solved by technology

However, there are also big problems in these single air supply outlet forms. For example, in some places with dense personnel or high mobility, since the form and position of the air supply outlet cannot be easily changed, the conventional air supply outlet form cannot meet the requirements of personnel on air volume and air supply. In addition, some industrial manufacturing plants, especially in certain narrow areas of closed spaces, have clear requirements and regulations on ventilation and air distribution, such as the air supply direction of the air conditioning system must meet a specific requirement, such as 60° downward, or it is required to take away pollutants by means of replacement air supply; secondly, for special personnel activity spaces, such as submarine cabins, spacecraft cabins, etc., the active personnel have a greater impact on the thermal environment and air quality inside the cabin. High demand, which requires that the air supply outlet at the end of the air conditioning system can not only achieve uniform low-speed air supply to reduce the feeling of blowing, but also meet the overall flow field inside the cabin to meet certain indicators, such as the speed range of 0.08-0.5m / s The flow field ratio is above 80%

At this time, ordinary air outlets on the market cannot meet the actual needs at all.

Therefore, due to the single form of the conventional air supply port, the installation position is fixed, and the air supply direction is not easy to adjust, it is difficult to meet the individual adjustment of personnel or the ventilation needs of special closed spaces.
