Problems solved by technology

However, since the volute-less fan is a single-inlet fan, the wind speed at the air inlet is high, so when the air flow is uneven, the fan is prone to eddy currents, and the noise is loud.

Abstract

The invention provides a pressure-equalizing noise-eliminating air conditioning unit which comprises a shell, an air inlet section, a first filtering section, a volute-free fan section, a second filtering section and an air outlet section, wherein the air inlet section, the first filtering section, the volute-free fan section, the second filtering section and the air outlet section are successively arranged in the shell according to an air feeding direction; air flow conveyed from the air inlet section passes through the first filtering section, the volute-free fan section and the second filtering section in turn and is discharged from the air outlet section. The pressure-equalizing noise-eliminating air conditioning unit provided by the invention can reduce the dust content of air entering into the volute-free fan section, and can effectively protect the volute-free fan section; meanwhile, the air flow is filtered and carded by the first filtering section, so that the air flow entering into the volute-free fan section is uniform, no eddy phenomenon is generated, the noise of the volute-free fan section is effectively reduced, and the running of the volute-free fan section is more stable.

Description

[0001] technical field [0002] The invention relates to the technical field of central air-conditioning, in particular to an air-conditioning unit using direct drive of a volute-less fan. Background technique [0003] For air-conditioning units without volute fans, they generally include air mixing, fans, primary and medium-efficiency filters, etc. The air volume of such air-conditioning units can meet the requirements, and the total length of the units is relatively short. However, since the volute-less fan is a single-inlet fan, the wind speed at the air inlet is high, so when the air flow is uneven, the fan is prone to eddy currents, and the noise is large. [0004] In view of this, it is necessary to propose further solutions to the above problems. Contents of the invention [0005] The object of the present invention is to provide a pressure-equalizing and noise-eliminating air-conditioning unit to overcome the deficiencies in the existing air-conditioning units usi...
