Excess refrigerant is collected within a refrigerant pot surrounding a portion of the return conduit connecting the outdoor coil operating as an evaporator during a heat pump heating cycle to the compressor creating a reduced pressure temperature relationship within the pot cavity causing the migration of liquid refrigerant through a small diameter tube connecting the pot to the liquid line leading from the indoor coil to the outdoor coil at a point upstream of the outdoor coil expansion valve.
