How Does a Refrigerator Compressor Work
A refrigerator compressor is a vital component of the refrigeration system. It plays a crucial role in maintaining the temperature inside the fridge and keeping your food fresh. Understanding how a refrigerator compressor works can help you understand the inner workings of your fridge.
At the heart of a refrigerator compressor is a motor that is responsible for compressing the refrigerant gas. The motor is typically powered by electricity and is designed to draw the necessary amount of amps to function properly.
When you set the desired temperature on your fridge, the compressor kicks into action. It starts by compressing the low-pressure refrigerant gas, which raises its temperature and pressure. This compressed gas then flows into the condenser coil located on the back of the refrigerator.
Inside the condenser coil, the compressed gas gives off heat and begins to cool down. As the gas cools down, it changes into a high-pressure liquid state. This high-pressure liquid then passes through a tiny opening called the expansion valve or the throttling valve.
As the high-pressure liquid passes through the expansion valve, it undergoes a sudden drop in pressure. This drop in pressure causes the liquid to evaporate, turning it back into a low-pressure gas. As it evaporates, it absorbs heat from the inside of the refrigerator, thereby cooling down the interior.
The low-pressure gas then returns to the compressor, and the cycle begins again.
Key Components of a Refrigerator Compressor
1. Motor: The motor is responsible for powering the compressor and drawing the necessary amount of amps to function.
2. Compressor: The compressor compresses the refrigerant gas, raising its temperature and pressure.
3. Condenser Coil: The condenser coil dissipates heat from the compressed gas, causing it to cool down and change into a high-pressure liquid state.
4. Expansion Valve: The expansion valve regulates the flow of the high-pressure liquid, causing a sudden drop in pressure and allowing it to evaporate.
5. Evaporator Coil: The evaporator coil is responsible for absorbing heat from the inside of the refrigerator, thereby cooling down the interior.
Conclusion
