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="" />

Application of synthetic compressor oil

At present, synthetic lubricants are widely used in the compressor field. Among them, oil-injected and oil-immersed rotary screw air compressors and large reciprocating compressors are one of the most used markets. For example, the sales volume of synthetic compressor oil in Western Europe was 6000t in the late 1980s, and it rose to 10000 in the early 1990s. The sales volume in the United States has exceeded 15,000 tons, and it is increasing at a rate of more than 10% per year.
