    Hmm Accumulator design

    Sawzalled open an accumuator to confirm what I believed its true function and design were. Two items of interest to me were a wire mesh filter at the bottom curve of the pipe, for oil return I assume and one very tiny 16th of an inch hole in the inside tubing of the accumulator about 1/2 inch before the tubing exits the accumulator. Would someone please explain what this hole is for.

    The hole on the upper part of the rod is used for safety, in case of excess liquid in the accumulator. The hole on the lower part of the inner rod ensures liquid expansion and return to the compressor of the oil that could be trapped inside the suction line accumulator.

    I believe the hole is to facilitate oil return. This is done by a venture effect. And limits the amount of oil that enters due to the size.

    Here's a link to Parker's catalog of accumulators and receivers. It gives an oversite of their accumulators. With the exception of Trane and newer 13 seer Rheems and Weatherkings, most heat pumps use accumulators http://www.parker.com/literature/Lit...Pdf%202007.pdf
