The answer to 'how does AC work' is that an air conditioner uses refrigeration to cool the air inside your home. It does this by circulating refrigerant through a closed loop system that absorbs heat from the indoor air and releases it outside. The key components are the compressor, condenser, expansion valve, and evaporator coil. The compressor pressurizes the refrigerant, which then flows through the condenser to release heat outside. The refrigerant then passes through an expansion valve that lowers the pressure and temperature, allowing it to absorb heat as it flows through the indoor evaporator coil. This cooled air is then circulated back into your home by the blower fan.
The air conditioning process is a continuous cycle that removes heat and humidity from the indoor air, providing cool, comfortable temperatures in your home. It's an efficient way to keep your living space comfortable, especially during hot summer months.
