Title:
FLUID STIRRING-BASED LIQUEFACTION PROMOTING APPARATUS INSTALLED ON PIPE PATH OF HEAT PUMP SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/070630
Kind Code:
A1
Abstract:
[Problem] Power consumption of a heat pump system is reduced by promoting homogeneous mixing of a refrigerant and a refrigerating machine oil. [Solution] An apparatus: includes a fluid-guide unit, which is assembled by concentrically combining a cylindrical casing and two circular plates inclusive of a big and a small plate and disposing circular plates having the same diameter to be adjacent to each other and installed in the casing; is installed on a path of a pipe; and stirs a fluid including a refrigerant and a refrigerating machine oil of a corresponding heat pump cycle. Respective chambers of the circular plates having a large and a small diameter are arranged at different locations to allow mutual losses to communicate with a plurality of other facing chambers. When a heat pump system is operated, a fluid including a refrigerant and a refrigerating machine oil passes through a static liquefaction promoting apparatus at a pressure from 0.2 mega Pascal to 10 mega Pascal and is repeatedly circulated through a cycle of the heat pump system, so that the apparatus stirs the fluid including a refrigerant and a refrigerating machine oil to homogeneously mix the corresponding fluid.
