Device for enhancing pulsing property of supply airflows

Abstract

The invention relates to a device for enhancing the pulsing property of supply airflows, which comprises an air-conditioning shell and at least one inclined flow fan, wherein the air-conditioning shell is provided with an air inlet and an air outlet; the air outlet position is provided with a movable shutter mechanism used for regulating an air direction; each inclined flow fan comprises an impeller and a rotating shaft; the impeller can rotate under the blowing of air-conditioning air, and the impeller is arranged on the air outlet region of the air-conditioning shell through the rotating shaft. The device for enhancing the pulsing property of the supply airflows, which is disclosed by the invention, is simple in structure and easy to manufacture and can enhance the pulsing property of the air-conditioning supply airflows, enhance the turbulent intensity of indoor air and enhance the heat comfortable sensation of personnel inside an air-conditioning room.

Description

technical field [0001] The invention relates to the technical field of air conditioning and ventilation equipment, in particular to a device for improving the pulsation performance of air supply airflow. Background technique [0002] People spend 80%-90% of their time in various closed indoor environments. The turbulent intensity of indoor air and the design of airflow organization will have a certain impact on the human body's sense of blowing and thermal comfort. Indoor air-conditioning outlets in conventional small-space buildings are adjustable louvers or slits. Although this type of air supply port can change the flow direction of the airflow by adjusting the angle of the louvers as required, the airflow direction generated is single and the flow velocity is uniform. If you stay in this air-conditioned environment for a long time, the human body will experience a blowing sensation, and the thermal comfort of the human body is relatively poor.
