In one embodiment, the evaporator assembly 11 is nested in the first collecting hood 12 and is attached to the inner wall of the first collecting hood 12, so as to completely seal the second heat exchange surface 112 side of the evaporator assembly 11 and prevent the air flow from escaping, and thus, when the evaporator assembly 11 enters from the first heat exchange surface 111 side, the air is more uniformly contacted with the evaporator surface. Thereby improving the heat exchange efficiency.

As will be understood, the heat exchange process of the evaporator assembly 11 is completed by the heat exchange between the indoor air and the refrigerant in the evaporator assembly 11 through the action of the first volute casing assembly 13, and the evaporator assembly 11 absorbs the heat in the indoor air to lower the indoor air from a high temperature to a low temperature, thereby completing the cooling process of the evaporator assembly 11.

The second volute assembly 23 is used for pumping outdoor air from the third heat exchange surface 211 to the fourth heat exchange surface 212 to exchange heat with the refrigerant in the condenser assembly 21, and then the outdoor air is collected by the first collecting cover 12 and blown to the outdoor. Therefore, the air flow is regulated through the flow collecting effect of the second flow collecting cover 22, the air flow is concentrated, the surface contact between outdoor air and the condenser assembly 21 is more uniform, the heat exchange efficiency of the condenser assembly 21 is improved, and the refrigerating efficiency of the refrigerating module 100 in the air-conditioning range hood is further improved.

Preferably, in one embodiment, the third heat exchange surface 211 and the fourth heat exchange surface 212 are disposed opposite to each other, so as to ensure that the heat exchange area with the outdoor air of the condenser assembly 21 is maximized and the circulation path of the outdoor air during heat exchange is minimized.

In one embodiment, the condenser assembly 21 is nested in the second collecting cover 22 and is attached to the inner wall of the second collecting cover 22, so that the fourth heat exchange surface 212 side of the condenser assembly 21 is completely sealed to prevent the air flow from escaping, and the air is more uniformly contacted with the evaporator surface when the condenser assembly 21 is fed from the third heat exchange surface 211 side. Thereby improving the heat exchange efficiency.

It will be appreciated that the heat exchange process of the condenser assembly 21 is completed by the heat exchange of the indoor air with the refrigerant in the condenser assembly 21 by the action of the second volute assembly 23, and the condenser releases heat to the outdoor air to raise the outdoor air from a low temperature to a high temperature, thereby completing the cooling process of the condenser assembly 21. The flow path of the air flow is from the third heat exchange surface 211 to the fourth heat exchange surface 212, and then the air flow passes through the second collecting hood 22 and is blown out of the room by the second volute assembly 23.

In one embodiment, referring to fig. 6 to 8, the second collecting cover 22 also has a windward opening, a collecting chamber b and a collecting outlet c, the condenser assembly 21 is nested on one side of the second collecting cover 22 where the windward opening is located, and the area of the collecting outlet c is smaller than that of the windward opening, and after entering the collecting chamber b of the second collecting cover 22 through the windward opening of the second collecting cover 22 and collecting, the outdoor air having exchanged heat with the condenser assembly 21 flows back to the outside from the collecting outlet c of the second collecting cover 22, thereby achieving the collecting and air flow regulating effects of the second collecting cover 22.

In one embodiment, referring to fig. 1, the second volute assembly 23 includes a second wind wheel 231, a second volute inlet 232 and a second volute outlet 233, the second volute inlet 232 is disposed opposite to the collecting outlet c of the second collecting cover 22, and the second volute outlet 233 is communicated with the outdoor. After flowing out of the collecting outlet c of the second collecting cover 22, the air enters the second volute assembly 23 through the second volute inlet 232, the second wind wheel 231 is controlled to rotate to blow the entering air to the outside through the second volute outlet 233, so that the air with higher temperature after heat exchange with the condenser assembly 21 is blown to the outside, and the indoor and outdoor heat exchange effect is achieved through the condenser assembly 21 and the evaporator assembly 11.

Specifically, the second heat exchange component 20 is also installed indoors, and in order to achieve communication between the third heat exchange surface 211 and the second volute outlet 233 with the outside, an air duct may be correspondingly installed or a certain improvement may be made on the wall, so as to achieve heat exchange between the condenser assembly 21 and the outside.

In one embodiment, in the first collecting cover 12 and the second collecting cover 22, the vertical distance between the plane of the windward opening and the plane of the collecting outlet c is 40-55mm, the air flow path with the depth exceeding 55mm is too long, the refrigerating effect is poor, the air flow path with the depth less than 40mm is too short, and the wind speed is not uniform. Therefore, the depth of the inner cavity of the first collecting hood 12 and the second collecting hood 22 is preferably 50mm, so that the energy loss rate of cold air entering the first volute assembly 13 and hot air entering the second volute assembly 23 is low, and the refrigeration efficiency is improved.

If the furthest distance between the first volute assembly 13 and the second volute assembly 23 is less than 150mm, the cooling air flow path in the connecting copper pipe between the evaporator assembly 11 and the condenser assembly 21 is too short, resulting in poor cooling. Therefore, the installation distance is limited to 150-250 mm, and the refrigeration efficiency can be improved while the economical efficiency is ensured.

Preferably, the vertical distance between the plane of the collecting outlet c of the first collecting hood 12 and the plane of the collecting outlet c of the second collecting hood 22 is 200mm, that is, the farthest distance between the first volute component 13 and the second volute component 23 after being installed is 200mm, which is not only beneficial to improving the heat exchange efficiency of the air-conditioning range hood, but also reduces the development cost; meanwhile, the stability of the whole structure of the air-conditioning range hood is improved.
