There’s nothing quite like the relief that air conditioning offers you on a hot and humid summer day, which is why air conditioners are now standard equipment in most American homes. According to the U.S. Energy Information Administration (EIA), approximately 87 percent of households have air conditioners, but few homeowners understand how they work. Here’s a brief explanation of the science behind your AC’s cooling magic.

The Cooling Process

The cooling process in your air conditioner works by extracting heat and humidity from the air, which leaves your home feeling cooler and dryer. This scientific feat is achieved by converting the refrigerant that circulates through the system’s main components from a gas to a liquid and back again:

  • Compressor. Refrigerant enters the compressor in a cool gaseous form and is pressurized into a hot gas.
  • Condenser. The condenser pulls heat from the gas and dumps it outside, turning the refrigerant into a cool liquid.
  • Evaporator. The cooled liquid is squeezed through a small valve into the evaporator where it pulls heat from household air as it evaporates into a gas.
  • Blower. A blower disperses the cooled air throughout your home, and the cooled gas is returned to the compressor to start the cycle all over again.

Energy-Efficiency Features

The refrigeration cycle needs energy in order to operate, and recent advancements in technology have produced energy-efficient air conditioners that can significantly reduce your monthly utility bills. Innovative energy-efficiency features include variable-speed fans and two-stage compressors that run on lower settings when cooling demands are low.
