Refrigerating cycle in direct cooling type refrigerator

摘要

The refrigeration cycle of the direct-cooling refrigerator of the present invention, in particular the operation of the refrigeration cycle to achieve the maximum heat exchange efficiency with the optimized operation of the refrigeration cycle even if the compressor operates with only a small cooling power through the improvement of the overall refrigeration cycle. It is intended to provide a structure.;To this end, the present invention is a compressor for compressing a refrigerant; A condenser for condensing the compressed refrigerant while passing through the compressor; A flow rate controller configured to enable a flow rate adjustment of the condensed refrigerant while passing through the condenser, and selectively distribute a flow of the condensed refrigerant; An expansion valve for a freezer compartment for expanding the refrigerant provided from the flow controller; A freezer compartment evaporator configured to exchange heat by receiving the expanded refrigerant through the expansion valve for the freezer compartment; At least two or more refrigerating compartment expansion valves provided on a conduit separate from the expansion valve for the freezing compartment to expand the refrigerant provided from the flow controller; In addition, the refrigerator compartment evaporator for receiving heat exchanged through the refrigerant expanded through the expansion valve for the refrigerating chamber, including: wherein the refrigerating chamber expansion valve is characterized in that the refrigerant flow distance is formed shorter than the expansion valve for the freezer compartment. Provided is a refrigeration cycle for a direct-cooling refrigerator.;Direct-cooling refrigerator, freezing cycle, refrigerant flow guide valve, flow regulator, damping part
