Abstract

The invention relates to a noise reduction structure of an air conditioning system. The noise reduction structure of the air conditioning system comprises a vehicle body and a draught fan assembly arranged on the outer side of the top of the vehicle body, and a noise blocking piece used for blocking noise generated by the draught fan assembly is arranged between the draught fan assembly and the top of the vehicle body. According to the noise reduction structure of the air conditioning system, noise generated by operation of the draught fan assembly is blocked through the noise blocking piece arranged between the top of the vehicle body and the draught fan assembly, the noise is prevented from being transmitted into the compartment from the top of the vehicle body and the framework, vibration and noise in the compartment are greatly reduced, and the comfort degree of the whole vehicle is improved.

Description

technical field [0001] The invention relates to a noise reduction structure of an air conditioning system. Background technique [0002] The air-conditioning system of a passenger car mainly includes a compressor, a high-pressure medium pipe, an air-conditioning pan, and an air-conditioning duct. The air-conditioning pan is equipped with a fan assembly, which includes a condenser fan and an evaporator fan. After the air-conditioning system on the bus is turned on, the air-conditioning compressor and the fan assembly will generate a lot of vibration and noise during operation, resulting in uncomfortable rides in the compartment and complaints from passengers. [0003] The announcement number is CN206257017U, and the announcement date is 2017.06.16. The Chinese utility model patent discloses a noise reduction device for an air conditioner. The air inlet is provided with an air intake pipeline, which forms an air intake port 6, and the air outlet is provided with an exhaust pi...
