Abstract
A combined refrigerant receiver, suction gas accumulator, and heat exchanger is provided and is particularly useful in connection with a transport refrigeration unit, and includes an internal concentrically disposed receiver 46 in the upper portion of an accumulator shell 40, the disposition providing an annular space 48 between the receiver and accumulator shell, in which is located a helically wound finned tube heat exchanger 56 which carries warm liquid refrigerant from the receiver to an outlet of the shell connected to an evaporator, with cold suction gas entering the shell at 52 and passing over the external fins 60 on the heat exchanger to exit the shell at 66.
Claims8
For a refrigeration unit including a refrigerant compressor, a refrigerant condenser having an inlet and outlet, and a refrigerant evaporator having an inlet and outlet, a combined liquid refrigerant receiver, refrigerant suction gas accumulator, and refrigerant heat exchanger, comprising:
- an outer cylindrical shell serving as the accumulator and having a refrigerant gas inlet and a refrigerant gas outlet;
- an inner cylindrical casing, concentrically disposed within said shell to provide an annular space therebetween, and serving as the liquid refrigerant receiver, said receiver having an inlet connected to said condenser outlet, and an outlet located internally of said shell;
- and
- a heat exchanger located in said annular space and having an inlet connected to said receiver outlet and an outlet in communication with said evaporator inlet.
