How Air Conditioning Works

At its core, the principle of air conditioning relies on the refrigeration cycle. This cycle involves absorbing heat from the indoor air and discharging it outside, resulting in a cooler indoor atmosphere. Here’s how it works:

1. Evaporation: Inside the evaporator coil, refrigerant absorbs heat from the indoor air, turning from a liquid into a gas.
2. Compression: The gaseous refrigerant flows to the compressor, where it is compressed under high pressure and temperature.
3. Condensation: The hot, high-pressure gas moves to the condenser coil, losing heat to the outdoors and reverting back to a liquid state.
4. Expansion: This liquid refrigerant then passes through an expansion valve, allowing it to drop in pressure and temperature before entering the evaporator coil again, and the cycle continues.
