Problems solved by technology

Its disadvantages are: the structure of the existing muffler is fixed, according to the actual heat load when the displacement of the compressor is changed, the displacement of the compressor is different, and the noise of the sucked refrigerant will also be different. The fixed muffler structure cannot solve the pulsating noise under different suction pressures according to the amount of inhaled refrigerant, and, for the existing muffler structure inside the compressor, there are still complex structures, high process costs and manufacturing and assembly problems. Inconvenience and other issues

Abstract

The invention relates to the field of vehicle engineering, and provides a compressor, an air conditioning system and a vehicle. The compressor comprises an air suction passage and an air suction chamber, the air suction chamber communicates with the air suction passage through an air suction opening, a silencer structure is arranged in the air suction passage, the silencer structure is arranged tobe capable of moving in the air suction passage according to the exhaust volume of the compressor so as to adjust a blocking area of the air suction opening, and an opening area of the air suction opening adapts to the size of the exhaust volume of the compressor. According to the compressor, the structure of the position which a refrigerant of the compressor flows into under different loads canbe changed adaptively, so that noise of the compressor is effectively reduced; and moreover, the internal structure of the compressor is simple, the manufacturing and assembling difficulty is low, andthe cost is low.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a compressor, an air conditioning system and a vehicle. Background technique [0002] The air conditioning system is an important part of the vehicle, and it has received more and more attention, especially the NVH performance of the air conditioning system, which plays a very important role in the field of the vehicle's air conditioning system. At present, more and more refrigerants are sucked in the cabin The pulsation has attracted a lot of attention, especially when the compressor of the air conditioning system is working, pulsation noise will be generated on the suction side, which has a great impact on NVH performance. The existing improvement technology is to connect the suction pipe to the compressor of the air conditioning system Add a muffler on the road or inside the compressor to alleviate the pulsation noise problem. Its disadvantages are: the structure ...
