1. A refrigerant system using a refrigerant to transfer heat between air and a fluid, wherein the air is supplied to a comfort zone, comprising:

  • a compressor adapted to compress and discharge the refrigerant;

    a fluid heat exchanger having a refrigerant passageway in heat transfer relationship with the fluid;

    a primary heat exchanger that places the refrigerant in heat transfer relationship with the air;

    a secondary heat exchanger exposed to said air;

    a primary refrigerant flow restriction that helps couple the primary heat exchanger to the fluid heat exchanger;

    a secondary refrigerant flow restriction that helps couple the primary heat exchanger to the secondary heat exchanger; and

    a flow divider having an inlet, a first outlet and a second outlet, wherein the inlet is adapted to receive the refrigerant discharged from secondary heat exchanger, the first outlet being adapted to discharge a first portion of the refrigerant toward the primary heat exchanger and the second outlet being adapted to discharge a second portion of the refrigerant toward the refrigerant passageway of the fluid heat exchanger, wherein the first portion has a greater concentration of refrigerant in a liquid state than the second portion.
