ABSTRACT:
A method of assembling suction accumulators is provided. A suction accumulator as employed in a refrigeration system conventionally comprises a cylindrical casing, a pair of end closures therefor, an inlet tube, an outlet tube, and a stand pipe. In applicant's assembly process, the inlet and outlet tubes are constructed essentially of copper. The assembly method of this invention is practiced by securing the stand pipe with end cap attached to the top end closure, preferably furnace brazing the end closures to the cylindrical casing, inspecting the metering orifice in the end cap of the stand pipe by viewing the same through the open top end of the stand pipe, and inserting the inlet and outlet tubes through openings in the top end closure and brazing them to said closure by induction or furnace brazing techniques. The disclosed assembly method may also be practiced with a heat exchanger--suction accumulator combination.
