How Air Conditioners Function

Refrigeration Cycle Explained

Air conditioners operate based on a principle called the. refrigeration cycle , which is essential for cooling indoor spaces. This cycle revolves around a refrigerant—a special fluid that absorbs heat from inside your home and releases it outside, effectively lowering the indoor temperature. The process begins when the refrigerant enters the evaporator coil as a low-pressure, cool liquid. Here, it absorbs heat from the warm indoor air, causing the refrigerant to evaporate and turn into a gas. This absorption of heat cools the air, which is then circulated back into the room by a fan.

Next, this warm refrigerant gas flows to the compressor, usually located outside the building. The compressor pressurizes the refrigerant gas, raising its temperature and pressure significantly. After compression, the hot, high-pressure gas travels to the condenser coil, where it releases the absorbed heat to the outdoor air. As the refrigerant loses heat, it condenses back into a liquid form. This liquid then passes through an expansion valve, which reduces its pressure and temperature before it returns to the evaporator coil to repeat the cycle.

This continuous cycle is what enables air conditioners to remove heat from indoor spaces efficiently. Modern air conditioners also include additional components such as fans, filters, and thermostats that help regulate airflow, improve air quality by filtering dust and allergens, and maintain the desired temperature automatically.
