TUBE MUFFLER FOR LOW FREQUENCY REFRIGERANT NOISE ATTENUATION

A refrigerant muffler includes an elongate hollow interior defined by cooperation of an axially extending circumferential wall, a first axial end wall, and a second axial end wall disposed opposite the first axial end thereof. A first port for conveying a refrigerant into or out of the hollow interior is provided as a first opening extending through the circumferential wall to an inner circumferential surface thereof. A second port for conveying the refrigerant into or out of the hollow interior is provided as a second opening extending through the circumferential wall to the inner circumferential surface thereof. The first port is axially spaced apart from each of the first axial end wall and the second axial end wall and the second port is axially spaced apart from each of the first axial end wall and the second axial end wall.
