초록

A suction line/capillary tube assembly which provides improved heat exchange between the cool gaseous refrigerant conveyed by the suction line and the warm liquid refrigerant conveyed by the capillary tube in a refrigeration system. The assembly is generally characterized by the capillary tube being within and in direct thermal contact with the suction line wall along a substantial length thereof, which length is at least approximately two feet. In a first specific embodiment, the capillary tube is soldered to the inside of the suction line, as opposed t...

청구항

A method for providing heat exchange between the capillary tube and suction line of a reFrigeration system, which method comprises: providing a suction line having a pair of longitudinal ridges extending from the interior surface of the line toward the center of the line and cooperating with the portion of the interior surface therebetween to form a generally U-shaped internal channel of at least approximately two feet in length; placing the capillary tube within the U-shaped internal channel along at least approximately two feet thereof; and deforming t...
