Problems solved by technology

Many air-conditioning internal units of existing commercial air conditioners include centrifugal fans, motors, heat exchangers and other components. Because the direction of air intake and exhaust direction of centrifugal fans are perpendicular to each other, the size of commercial air conditioners is limited by this feature. It is difficult to reduce, and there are many restrictions on the installation position and direction of the centrifugal fan in th

Example Embodiment

[0020] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0021] Such as figure 1 Shown is a schematic structural diagram of an embodiment of the internal air conditioner of the present invention. In this embodiment, the internal air conditioner includes: an internal air duct 11 and a counter-rotating fan 2. The internal air duct 11 is in communication with the air inlet 12 and the air outlet 13 of the internal air conditioner, and the counter-rotating fan 2 is arranged in the internal air duct 11 for guiding airflow from the air inlet 12 to the air outlet along the internal air duct 11 13.

[0022] The internal air duct 11 can be formed inside the body 1 of the air conditioner internal unit, and the air inlet 12 and the air outlet 13 can be referred to figure 1 It is shown at both ends of the internal air duct 11 respectively. In another embodiment, the positions of the air inlet 12 and ...

Abstract

The invention relates to an air conditioner inner unit and an air conditioner. The air conditioner inner unit includes: an internal air duct (11) and a counter-rotating fan (2), the inner air duct (11) and the air inlet of the air conditioner inner unit ( 12) is in communication with the exhaust port (13), and the counter-cyclone fan (2) is arranged in the internal air passage (11) for guiding the airflow from the air inlet (12) along the internal air passage (11) flows to said exhaust port (13). In the present invention, a counter-rotating fan is installed in the internal air duct of the air conditioner to guide the air flow. Compared with the existing scheme of using a centrifugal fan or a larger-sized axial fan to meet the air supply requirements, the counter-rotating fan used in the present invention can Under the condition of meeting the same air supply demand, the occupied installation space is smaller, which can meet the installation requirements of more applicable occasions, especially the occasions with relatively compact installation space requirements.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner inner unit and an air conditioner. Background technique [0002] Commercial air conditioners are widely used, and different usage occasions make the requirements for commercial air conditioners also different. Take the internal air conditioner used on ships as an example. Due to the limited space on ships, there are very strict requirements on the size of commercial air conditioners. Many air-conditioning internal units of existing commercial air conditioners include centrifugal fans, motors, heat exchangers and other components. Since the air intake direction and exhaust direction of centrifugal fans are perpendicular to each other, the size of commercial air conditioners is limited by this feature. It is difficult to reduce, and there are many restrictions on the installation position and direction of the centrifugal fan in the design of the air conditioner. ...
