Abstract
A suction accumulator for use in a heat pump or air conditioning system includes an inlet tube that has a plurality of holes therein. One hole is preferably at the end of the inlet tube while the others are preferably of decreasing size and spaced apart from near the bottom of the accumulator upward along the inlet tube. Such an arrangement ensures that a vapor/liquid mixture of refrigerant and lubricant entering the accumulator does not cause excessive foaming during normal operation while quickly destratifying a stratified mixture that frequently occurs during periods of system inactivity or floodback.
