AI Technical Summary
In existing refrigerator refrigeration systems, the dryer filter is a separate component, which takes up space and increases layout complexity and assembly costs.
A drying and filtration chamber is integrated into the valve body of the electric switching valve and filled with molecular sieves to achieve the drying and filtration function, eliminating the need for assembly space and connecting pipelines of a separate drying filter.
It simplifies the layout of the refrigerator's refrigeration system, reduces costs, and improves the reliability and stability of the refrigeration system.
