A refrigeration distribution arrangement which improves the uniformity of coil temperature distribution along the length of an evaporator coil. The distribution arrangement is particularly beneficial when an evaporator coil is operating partially flooded with refrigerant, such as when refrigeration capacity is being reduced with a suction line modulation valve. Distributor tubes from a refrigerant distributor are inserted for at least first and second different dimensions into coil tubes which initiate a plurality of refrigerant circuits in the evaporator coil. In an exemplary embodiment, the first dimension is a relatively short dimension, and the second dimension is a relatively long dimension, such as about one-third of the coil length. The refrigerant thus expands at different locations across the coil length, initiating coil cooling at different coil locations. The discharge temperature of air (flowing across the evaporator coil into a served space is thus more uniform across the coil length.
