Abstract:
A suction muffler for a hermetically sealed compressor comprising:a housing having an inlet and an outlet; means for defining a flow path between the inlet and the outlet to accommodate refrigerant coursing therethrough; a first filter positioned in the outlet, at least a portion of the first filter defining a mesh through which the refrigerant can flow, the first filter acting to remove impurities from the refrigerant, to diffuse the refrigerant, and to attenuate noise generated from the flow of the refrigerant; and a second filter positioned in the flow path, at least a portion defining a mesh through which the refrigerant can flow, the second filter acting to damp an acoustic source in the housing, to remove impurities from the refrigerant, to diffuse the refrigerant, and to further attenuate noise generated from the flow of the refrigerant.
