Abstract:
A receiver-tank for use in a refrigeration cycle, wherein a condensed refrigerant is introduced into said receiver-tank and accumulated therein and only a 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 a 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; and 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 a refrigerant introduced into said tank main body via said refrigerant inlet passes through said flow-resistance layer upward to cause liquid stagnation of a liquefied refrigerant in said upper space, and the liquefied refrigerant flows out of said refrigerant outlet via said suction pipe.
