Abstract
A gas-liquid contactor for varying the mixing ratio of a non-azeotropic refrigerant circulated through a refrigeration cycle. A liquid returning pipe leading from a liquid refrigerant reservoir has a lower end which is opened downward into the container of the gas-liquid contactor at a position substantially on the axis of the container, so that the returned liquid refrigerant can be uniformly distributed over the entire region of the filler bed so as to enhance exchange of heat between the gaseous phase and the liquid phase of the refrigerant. A lower filler holder defining the lower end of a bed of filler in the gas-liquid contactor is convexed upward at its central portion so as to smoothly guide the flow of gaseous phase of the refrigerant into the filler bed.
