Fluid stirring and liquefaction promoting apparatus disposed on pipeline of heat pump system

A static type liquefaction promoting apparatus to be disposed on a pipeline of a heat pump system for the purpose of stirring and uniformly mixing the fluid containing refrigerant and refrigerator oil circulating therein comprising:

• an inner cylindrical casing having an inner cylindrical casing inlet and an inner cylindrical casing outlet on its axial ends, the peripheral wall of said inner cylindrical casing being formed with a plurality of pores so as to allow the fluid containing refrigerant and refrigerator oil flow in and out therethrough;
• one or more channelizing units each composed of a pair of large-diameter disks on its outer side and a pair of small-diameter disks on its inner side disposed in the axial alignment inside said inner cylindrical casing,
• said large-diameter disks each having a diameter consistent with the inner diameter of said inner cylindrical casing, being formed on its center with a flow hole and being formed on its inner surface with a honeycomb panel having polygonal cells,
• said small-diameter disks being formed on its outer surface with a honeycomb panel having polygonal cells,
• the honeycomb panels of said large-diameter disks and of said small-diameter disks being arranged to face each other such that each polygonal cell communicates with more than one opposing polygonal cells,
• the flow holes of the two large-diameter disks disposed nearest to the inlet and the outlet of said inner cylindrical casing being communicated with said inner cylindrical casing inlet and said inner cylindrical casing outlet thereof;
• and
• an outer cylindrical tank accommodating said inner cylindrical casing and having an outer tank inlet and an outer tank outlet,
• the outer tank inlet and the outer tank outlet being communicated with said pipeline;
• wherein
• the fluid containing refrigerant and refrigerator oil is circulated in the heat pump system with a pressure of 0.2 to 10 MPa.
