The role of the outside fan in an air conditioner, also known as the condenser fan, is to facilitate the heat transfer process. Here's how it works:
Heat Dissipation: Air conditioners operate by removing heat from the indoor environment and transferring it outside. The outside unit of an air conditioner contains a condenser coil, which gets hot as it receives the high-pressure, high-temperature refrigerant vapor from the compressor. The outside fan is responsible for dissipating this heat.
Air Circulation: The outside fan pulls ambient air from the surroundings and directs it over the condenser coil. As the hot refrigerant vapor flows through the coil, the fan blows air across it, causing the refrigerant to release heat and convert into a high-pressure liquid state. The circulating air helps to enhance the heat exchange process by carrying away the heat absorbed by the coil.
Removal of Heat: The movement of air created by the outside fan allows the heat energy from the refrigerant to transfer to the surrounding air. This process causes the refrigerant to cool down and transition back into a low-pressure, low-temperature vapor, ready to be circulated back inside to absorb more heat.
By expelling the heat absorbed from the indoor space, the outside fan plays a crucial role in maintaining the air conditioning system's efficiency and cooling performance. It ensures that the refrigerant remains at the right temperature and pressure levels for effective heat exchange.
