Composition principle of refrigeration system of refrigerator

Composition principle of refrigeration system of refrigerator Refrigerators have a larger cooling capacity than household refrigerators, and there are more refrigerants filled in the system. Therefore, a liquid storage tank is installed on the pipeline between the condenser and the filter, and a shut-off valve is installed on the tank to shut down the system for a long time. When closing the shut-off valve, the refrigerant liquid is stored in the tank.<img src="{{media url=&quot;Composition_principle_of_refrigeration_system_of_refrigerator.jpg&quot;}}" alt="" />
