ABSTRACT:
An evaporator of the plate-fin construction has attached a formed housing which together with the evaporator end plate comprises a suction accumulator. A liquid conduit passes through the accumulator and induces fluid from the accumulator into the evaporator via a venturi located in the conduit. A tube inserted into one tank of the evaporator is in direct connection to the accumulator and increases storage capacity of the accumulator. A field removable filter-drier assembly is installed in the exit tank or compartment of the evaporator. A baffle is located in the accumulator section and separates liquid from gas and allows mostly gas with entrained oil to flow to the compressor. A secondary flow path which opens under low charge conditions aids in oil return to the compressor.
