The invention relates to the technical field of air conditioning equipment, and discloses a duct type air conditioner which comprises a shell, a fan and a fan body. The heat exchanger is located in the shell; the volute fan is located in the shell and comprises a volute and an impeller, the volute comprises a first volute section and a second volute section which are sequentially arranged in the axial direction of the volute, the first volute section defines an installation space communicating with the air inlet, the impeller is located in the installation space, the inlet end of the second volute section communicates with the installation space, and the outlet end of the second volute section communicates with the installation space; and the outlet end of the second volute section is communicated with the heat exchanger. The second volute section in the volute is arranged on the axial side of the first volute section instead of being arranged in the radial direction of the first volute section, so that the situation that the second volute section occupies the radial size of the first volute section is avoided, the size of the first volute section can be increased, the diameter of the impeller can be increased, and therefore the service life of the impeller is prolonged. According to the volute, on the premise that the size of the whole machine is not increased, the diameter of the impeller is increased, the air volume and the air pressure are improved, and the air supply distance is increased.
Description
technical field [0001] The present application relates to the technical field of air conditioning equipment, for example, to an air duct machine. Background technique [0002] At present, centrifugal fans are generally used in air duct machines. The impeller is limited by the volute, and the radial size of the impeller is small. The air volume and air pressure provided are limited. However, increasing the fan speed will bring noise. Uneven wind and noise problems. Contents of the invention [0003] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is presented below. The summary is not intended to be an extensive overview nor to identify key / important elements or to delineate the scope of these embodiments, but rather serves as a prelude to the detailed description that follows. [0004] An embodiment of the present disclosure provides an air duct machine to solve the problems of uneven air supply and noise in the exi...
