The purpose of a fridge condenser is to release heat from inside the refrigerator to the surrounding environment. In a refrigerator’s cooling cycle, the condenser plays a crucial role in removing heat from the refrigerant gas, causing it to condense into a liquid state.

Here’s how it works:

1. Heat Removal: Inside the refrigerator, the evaporator absorbs heat from the interior, causing the refrigerant (typically a gas) to absorb this heat and turn into a gas state.
2. Compression: The compressor in the refrigerator then compresses this heated gas, raising its temperature and pressure. As the gas becomes pressurized, it releases even more heat.
3. Condensation: The hot, pressurized gas then flows through the condenser coils, usually located on the back or bottom of the refrigerator. These coils allow the gas to dissipate its heat to the surrounding air. As the heat is released, the gas condenses back into a liquid state.
4. Liquid Refrigerant: Once the refrigerant has released its heat and condensed into a liquid, it travels to the expansion valve, which regulates its flow into the evaporator, starting the cycle anew.

The condenser effectively acts as a heat exchanger, allowing the high-temperature, high-pressure refrigerant gas to transfer its heat to the cooler surrounding air or room, causing it to condense into a liquid form. This process is essential for maintaining the refrigerator’s interior at a lower temperature by removing the heat collected from the food and items stored inside.

Condensers in refrigerators can be of different types, such as air-cooled condensers (where the heat is dissipated to the surrounding air) or in some cases, more complex systems that utilize water or even fans to remove the heat from the condenser coils. Regardless of the design, the primary function remains the same: to release heat and turn the refrigerant gas into a liquid to enable the cooling cycle in the refrigerator.
