In air conditioners (AC), the liquid commonly used is a refrigerant. The refrigerant is responsible for absorbing heat from inside the room and releasing it outside, helping to cool the air.
There are different types of refrigerants used, but some of the most common ones include:
1. **R-22 (Chlorodifluoromethane)**: This was widely used but is being phased out because it can damage the ozone layer.
2. **R-410A (Puron)**: A more eco-friendly alternative to R-22, commonly used in modern AC units.
3. **R-134A (tetrafluoroethane)**: Used in some older and smaller air conditioning systems.
These refrigerants are in a gas form at normal temperatures but are pressurized and turned into a liquid inside the AC system. The liquid refrigerant absorbs heat from the air, and then it evaporates back into a gas as it moves through the system, carrying the heat outside.
