How Does a Central Air Conditioning Unit Operate?

A central air conditioning unit operates through a systematic process of cooling and circulating air within a home.

• Thermostat: The thermostat serves as the control center for the air conditioning unit, allowing users to set their desired temperature. When the indoor temperature rises above the set point, the thermostat signals the air conditioning system to activate.
• Compressor: The compressor is the heart of the air conditioning unit, located outside the home. It compresses refrigerant gas, raising its pressure and temperature, and prepares it for the condensation phase.
• Condenser Coils: The high-pressure refrigerant gas flows into the condenser coils, where it releases heat to the outside air. As the refrigerant loses heat, it transforms from a gas to a liquid, ready to return indoors for further cooling.
• Expansion Valve: The expansion valve controls the flow of liquid refrigerant into the evaporator coils inside the home. It allows the refrigerant to expand and cool, lowering its pressure as it enters the evaporator coils.
• Evaporator Coils: Inside the evaporator coils, the low-pressure refrigerant absorbs heat from the indoor air, causing it to vaporize. This process cools the air, which is then blown throughout the house via ductwork.
• Blower Fan: The blower fan circulates the cooled air through the ducts and into individual rooms. It is crucial for maintaining consistent airflow and ensuring that the entire home reaches the desired temperature.
• Return Air Ducts: After the air is circulated, it is pulled back into the system through the return air ducts. This cycle continues, providing ongoing cooling as long as the thermostat remains set to a temperature lower than the ambient temperature.
