Embodiment Construction

[0017] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0018] Such as figure 1 with figure 2 As shown, the working principle diagram of the wall-mounted air conditioner indoor unit and the cabinet type air conditioner indoor unit in the prior art, the indoor air first enters the cavity of the indoor unit through the air inlet 11 on the upper part of the air conditioner housing 1, and the effect of the cross-flow fan 12 Next, after the heat and humidity treatment with the heat exchange coil 13, the excess heat and humidity are discharged from the room, and the treated air enters the room through the air outlet 14 below to adjust the temperature and humidity of the indoor air.

[0019] Such as Figure 3~4 The be...

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.
