A method for cooling with a refrigerant based cooling system includes circulating a refrigerant in a main flow path of a refrigeration cycle including an accumulator, compressor, condenser and an evaporator, diverting a portion of flow to a bypass flow path from a location along the main flow path that is downstream the compressor and upstream the condenser and combining flow through the bypass flow path with flow through the main flow path downstream the condenser and upstream from the evaporator. The rate of flow through the bypass flow path may be dynamically controlled.
