What is a refrigerator compressor and how does it work?
A refrigerator compressor is a key component in the refrigeration cycle, responsible for circulating refrigerant throughout the system. It compresses the refrigerant gas, increasing its pressure and temperature, so it can release heat when it moves through the condenser coils. This process is essential for maintaining the cold temperature inside the refrigerator, allowing it to preserve food and other perishable items.
In simpler terms, the compressor acts like a pump that keeps the refrigerant flowing. As the refrigerant is compressed, it transforms from a gas into a high-pressure liquid, which then moves into the condenser. From there, it releases heat and turns into a liquid before entering the evaporator coils, where it absorbs heat from the refrigerator’s interior and cools the space down. This cycle continues until the required temperature is achieved.
