Refrigerator compressor how does it work

Last, the refrigerant evaporates to a gas due to raised temperature, and then flows back to the compressor, where the cycle starts all over again. The main component of a refrigerator that needs power is the compressor. It is essentially a pump which is driven by a motor. The hum you hear when the fridge is on is that of the compressor working. The thermostat controls the temperature of the fridge by switching on-and-off the compressor. Return To Shop. All charges are billed in INR.

Inside, the refrigerant is cooled down and condenses, meaning it turns from a gas back into a liquid. The evaporator is located inside a refrigerator and is the part that makes the items in the refrigerator cold. As the refrigerant turns from a liquid into a gas through evaporation, it cools the area around it, producing the proper environment for storing food.

The capillary tube is a thin piece of tubing that serves as an expansion device. The liquid refrigerant is routed through the capillary tube and sprayed into the low-pressure environment of the evaporator. The thermostat controls the cooling process by monitoring the temperature and then switching the compressor on and off.

When the sensor senses that it's cold enough inside a refrigerator, it turns off the compressor. If it senses too much heat, it switches the compressor on and begins the cooling process again.

Refrigerators work by causing the refrigerant circulating inside them to change from a liquid into a gas. This process, called evaporation, cools the surrounding area and produces the desired effect. You can test this process for yourself by taking some alcohol and putting a drop or two on your skin. As it evaporates, you should feel a chilling sensation - the same basic principle gives us safe food storage. For instance, dirty condenser coils will make the compressor have to work harder.

That said, compressors are not usually the root cause of your refrigerator not cooling. Many other components should be ruled out first, such as the condenser, evaporator, start relay, and temperature control thermostat to name a few. Powered by ServicersWeb. Facebook Twitter Youtube.

This is where the compressor gets its name. The compressed gas then gets sent to the condenser, where the refrigerant is liquefied by lowering its temperature.

The expansion valve then lowers the refrigerant temperature and pressure, causing about half of it to evaporate. The evaporator takes the remaining liquid refrigerant and turns it back into a gas.
