摘要： Disclosed are a flow guiding ring structure, an axial flow fan and an air conditioner, relating to the field of noise reduction, and used for reducing the pneumatic noise of the axial flow fan during use on the premise of guaranteeing the air outflow amount of the fan. The flow guiding ring structure includes a ring body (1). The ring body (1) includes a closed cavity (11) and a through hole (12). A minimum diameter position of the ring body (1) is provided with an opening (13). The cavity (11) communicates with the through hole (12) via the opening (13). A fluid in the through hole (12) is able to enter the cavity (11) through the opening (13). According to the above technical solutions, on the premise of guaranteeing the Venturi tube effect of the flow guiding ring structure, an opening structure is added on a surface, and turbulent energy of a blade top airflow is transmitted out of a fan area in a radial direction, so that the aim of noise reduction is achieved.

摘要： The invention discloses an air outlet protection structure, an outdoor unit of an air conditioner and a method for designing an air outlet protection structure. The air outlet protection structure comprises: a central circular disk (10); and a radiating rib (20), extending from an outer edge of the central circular disk (10) to a direction away from the central circular disk (10). An included angle between a first side surface (21) of the radiating rib (20) and a central axis of the central circular disk (10) is a, as formula (I), where V r is a flowing velocity of an airflow in a rotation direction of a blade, V z is a flowing velocity of the airflow in an axial direction of a blade shaft, I is a distance from a point on the first side surface (21) of each radiating rib (20) to the central axis of the central circular disk (10), and f is a rotation frequency of the blade shaft. The air outlet protection structure, the outdoor unit of the air conditioner and the method for designing an air outlet protection structure are determined according to the characteristics of a flow field of an air duct, and can reduce the hindering effect of an air outlet protection apparatus on a fluid as far as possible, thereby improving the air output volume of a fan and reducing the noise of the entire outdoor unit of the air conditioner.
摘要翻译：本发明盘松动到空气出口保护结构的空调机的室外机和用于空气出口保护结构的设计方法。空气出口保护结构包括：一个中央的圆形盘（10）; 和散热肋（20）从在中央圆盘（10）的外边缘延伸的方向从中央圆形盘（10）的距离。散热肋（20）和中心圆盘的中心轴线（10）的第一侧表面（21）之间的夹角为A，如式（I），其中V r为气流在流动的速度叶片的旋转方向，V z是在叶片轴的在轴向方向上的气流的流动速度，I是从每个辐射肋（20）的第一侧表面（21）上的点到中心的距离中央圆形盘（10），和f的轴线是叶片轴的旋转频率。空气出口保护结构，所述空调机的室外机和用于空气出口保护结构的设计方法是确定性的开采雅丁到空气管道的流场的特性，并能减少空气出口保护装置的阻碍作用上尽可能的流体，从而提高了风扇的风输出音量和降低的空调机的整个室外机的噪音。

摘要： The present invention provides an air conditioner including an air conditioner body (1), air intake plates, and a filter screen. The air conditioner body is provided with an air inlet and an air outlet. The air intake plates cover the air inlet and each has an air intake grid. The air intake plates are hingedly connected to the air conditioner body (1) and are capable of being switched between an expanded state and a closed state. The filter screen is disposed between the air intake plates and the air inlet and is configured to filter air entering the air conditioner body (1) from the air intake grid (9). In the present invention, the air intake plates are designed to be a structure capable of expanding and closing. When the air intake plates are in the expanded state, air is taken in through the entire air inlet instead of from the air intake grid (9), thereby increasing the air intake area. When the air intake plates are in the closed state, the air intake area is reduced, but the amount of the intake air reaches a certain extent, without affecting the appearance of the air conditioner.

摘要： A heat pump air conditioning system and a control method. The heat pump air conditioning system includes: a compressor (1); an indoor unit heat exchanger (2), an outdoor unit heat exchanger (3) and a throttling device (4); a refrigerant circulation loop, connecting the compressor (1), the indoor unit heat exchanger (2), the outdoor unit heat exchanger (3) and the throttling device (4) in series; the heat storage module (5), disposed in the refrigerant circulation loop and configured to absorb heat from refrigerant in the refrigerant circulation loop and store heat when heat storage defrosting is required, and to heat the refrigerant in the refrigerant circulation loop when the outdoor unit heat exchanger is defrosted. The heat pump air conditioning system can store excess heat of the system for defrosting when indoor heat load is low, and release heat for defrosting by means of the heat storage module during a defrosting processwhile continuing supplying heat to a room to ensure that room temperature remains unchanged, thereby improving comfort of the room.
