Abstract

The present invention relates to a structure of a refrigeration cycle of a refrigerator, and in particular, a pressure-depleted refrigerant having passed through capillary tubes by installing respective evaporator pipes on both upper and lower surfaces of a cold plate return duct through which a return coolant from a freezer compartment and a refrigerating compartment passes. As the gas absorbs the surroundings and heat as it passes through the evaporator pipe, it is possible to reliably cool the return chiller from the elevated temperature freezer and refrigerating compartment that has passed around the plate of the cold return duct, thereby supplying cold cold air separately to the freezer and the refrigerating compartment. At the same time, it is possible to maintain a constant temperature, and to add the defrosting capacity of the defrosting plate and the evaporator pipe with low power consumption during defrosting, thereby significantly improving the cooling performance of the refrigerator.

As a technical means for imparting a cooling function to the frosted plate in the cold return duct, the evaporator having cooling fins arranged at regular intervals on the frosted plate of the cold return duct through which the return cold air from the freezing compartment and the refrigerating compartment flows in and passes. A pipe is installed and connected to the compressor located in the machine room, and the cooling fins arranged in the freezing chamber direction of the evaporator pipe installed on the upper surface of the cooling plate are installed on the lower surface of the cooling plate, while the cooling plate is sealed in the central longitudinal direction. It is formed so that the cooling temperature of the return cooler from the freezer compartment and the refrigerating compartment is different by forming a tighter spacing interval than the cooling fins arranged in the evaporator pipe of the refrigerating compartment. By installing the evaporator pipe in the freezer compartment Is connected to the evaporator pipe and the direction of the pipes of the refrigerating compartment evaporator direction connected to the accumulator is characterized in that the speech so that the compressor.
