The Cooling Cycle

At the core of every air conditioning unit lies a fundamental cooling cycle driven by AC refrigerants. This cycle involves four key components: the evaporator coil, the compressor, the condenser coil, and the expansion valve. AC refrigerants flow through this cycle, transitioning between gaseous and liquid states to facilitate heat exchange.

  1. Evaporator Coil: AC refrigerant enters the evaporator coil as a low-pressure gas. As warm indoor air blows across the coil’s fins, the refrigerant absorbs heat from the air, causing it to evaporate and transform into a low-temperature gas.
  2. Compressor: The now-cooled gas refrigerant is drawn into the compressor, typically located outside the home. The compressor compresses the gas, raising its temperature and pressure. This process increases the energy of the refrigerant, making it ready for the next phase.
  3. Condenser Coil: The high-pressure, high-temperature gas refrigerant then flows into the condenser coil. Here, outdoor air blows across the coil, dissipating the heat absorbed from indoors. As a result, the refrigerant condenses back into a high-pressure liquid.
  4. Expansion Valve: The high-pressure liquid refrigerant moves through the expansion valve, where it undergoes a sudden drop in pressure. This causes the refrigerant to rapidly expand and cool down, returning it to a low-pressure gas state. The cycle then begins anew.
