Description

technical field [0001] The invention relates to the technical field of refrigeration processing, in particular to a method and a device for calculating the gas-liquid separation speed of a horizontal separation container. Background technique [0002] The separator is an important device in the refrigeration system. In the early stage of the design of the refrigeration system, it is necessary to select and calculate various types of containers. Among them, the separator can be divided into vertical separation container and horizontal separation container according to the shape. For the horizontal separation container, its maximum separation capacity can be expressed by the separation speed of the refrigerant liquid in the container. The separation speed needs to be determined according to the structure of different horizontal separation containers, different refrigerants, heating temperature, etc. working parameters to determine. However, in practice, it is found that the ...
