A Closer Look at Air Conditioning Mechanisms
Understanding who invented air conditioning also includes grasping how it works. Air conditioning systems are based on four main components: the evaporator, compressor, condenser, and expansion valve.
The Four Essential Components of Air Conditioning
- Evaporator: This is where the refrigerant absorbs heat from the air, cooling it down. The temperature of the air drops as it passes over the evaporator coils.
- Compressor: The compressor pumps the refrigerant through the system. It compresses the low-pressure refrigerant gas into a high-pressure gas, a crucial step in the cooling cycle.
- Condenser: Located outside the home, the condenser releases the absorbed heat, allowing the refrigerant to cool down and return to a liquid state.
- Expansion Valve: This component reduces the pressure of the refrigerant before it re-enters the evaporator, allowing it to absorb heat more efficiently.
This precise process demonstrates the ingenuity behind air conditioning technology.

What is air conditioning, and how does it work?
Air conditioning refers to the process of altering the properties of air, primarily to control temperature and humidity. It works by removing heat and moisture from the indoor air through a refrigeration cycle. This cycle typically involves refrigerants circulating through various components like evaporators, compressors, and condensers, which absorb and release heat.
The system operates by drawing warm air from the environment into the air conditioning unit. The refrigerant inside the coils of the unit absorbs the heat from the air and converts from a liquid to a gas. The compressor then compresses this gas, which raises its temperature before it is sent to the condenser, where it releases the heat to the outside environment. This continuous cycle cools the air and helps maintain a comfortable indoor climate.
