Abstract:
A receiver-tank for use in a refrigeration cycle, wherein condensed refrigerant is introduced into said receiver-tank and accumulated therein and only liquefied refrigerant flows out of said receiver-tank, said receiver-tank, comprising:a tank main body having a refrigerant inlet and a refrigerant outlet each provided in a bottom wall of said tank main body; a flow-resistance layer for reducing a flow velocity of refrigerant passing through said flow-resistance layer, said flow-resistance layer being provided in said tank main body such that an upper space is formed above said flow-resistance layer; a suction pipe provided in said tank main body, said suction pipe having an upper end opened toward said upper space and a lower end communicated with said refrigerant outlet, whereby refrigerant introduced into said tank main body via said refrigerant inlet passes through said flow-resistance layer upward to cause liquid stagnation of liquefied refrigerant in said upper space, and the liquefied refrigerant flows out of said refrigerant outlet via said suction pipe, and wherein said suction pipe is constituted by said refrigerant outlet.
