What is the basic principle of how an air conditioning system works?

The basic principle of how an air conditioning system works is based on the transfer of heat. An air conditioning system effectively removes heat from the indoor environment and expels it outside, thereby cooling the interior space. This process involves the use of refrigerants, which absorb heat from the indoor air as they evaporate and then release that heat to the outside air when they condense back into a liquid state.

This operation allows the air conditioning system to maintain a comfortable indoor temperature by continuously cycling air and removing excess heat. The system relies heavily on the principles of thermodynamics, utilizing compression and expansion processes in the refrigeration cycle to achieve the desired cooling effect.

In contrast, generating cool air through chemical reactions does not accurately describe the functioning of standard air conditioning systems. While some specialized cooling systems may use chemical processes, they are not the general principle for traditional air conditioning. Similarly, solely using water to cool indoor air overlooks the comprehensive mechanics of heat exchange and the importance of refrigerants in most air conditioning systems. The notion of circulating air without changing its temperature also diverges from the fundamental purpose of air conditioning, which is indeed to lower the temperature through heat removal.
