What is the refrigerator compressor used for

　Refrigerators use evaporative cooling or vaporization to absorb heat to achieve the purpose of refrigeration. The throat of the refrigerator is filled with a refrigerant known commercially as Freon, commonly known as refrigerant. A commonly used one is difluorodichloromethane, which is a colorless, odorless and non-toxic gas with a boiling point of 29°C. Freon is pressurized by the compressor when it is in a gas state.

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="" />

The internal structure and characteristics of the micro servo motor

A miniature servo motor includes a small DC motor, a set of variable speed (reduction) gear sets, a feedback adjustable potentiometer and an electronic control board. Among them, the high-speed rotating DC motor provides the original power and drives the variable speed (reduction) gear set to produce a high torque output. The greater the gear ratio of the gear set, the greater the output torque of the servo motor, that is to say, the greater the weight it can bear, the lower the speed of rotation it will be.
