The improved refrigeration system of the present invention includes an accumulator with a diffuser pipe extending downwardly into the upper end of a vapor refrigerant tank, the diffuser pipe extending from an evaporator and discharging vapor refrigerant therefrom into the tank. The diffuser pipe includes a lower end located within the interior of the tank which is expanded in diameter relative to the upper end, thereby reducing the velocity of fluid flowing through the pipe and entering the accumulator tank. A diffusion plate is mounted in the lower end of the diffuser pipe, to further diffuse fluid flowing therethrough. The improved refrigeration system also includes a tee having a stem portion extending horizontally from the condenser of the system, and a pair of upper and lower arms connected in a vertical orientation to the stem. The tee lower arm is connected to the receiver and the upper arm is connected to a purge connection. The improved refrigeration system further includes a two stage refrigeration system with the condenser of the high stage having a second section with a desuperheating coil therein to cool vapor refrigerant from the low stage compressor and supplying it to the high stage accumulator.
