1. Who invented Air conditioner?1902
2. What is the category?Mechanical refrigeration system
3. What is the inventor?Willis Carrier
4. What does an air conditioner do to make a room cool?It moves heat from inside the room to outside. The refrigerant absorbs heat in the indoor coil, turns into gas, and then releases that heat outside. This keeps the indoor air cooler.
5. How does the refrigerant change inside an air conditioner?Inside the evaporator coil, the liquid refrigerant absorbs heat and becomes a low‑pressure gas. It travels to the compressor, where it is pressurized and heated. Then it goes to the condenser coil outside, where it releases heat and turns back into liquid.

Vapor-Compression Refrigeration Cycle: A thermodynamic process using refrigerant phase changes to transfer heat from a colder to a hotter area.
Refrigerant: A working fluid that undergoes phase transitions to absorb and release heat in a refrigeration system.
Global Warming Potential (GWP): A measure of how much heat a greenhouse gas traps in the atmosphere over a specific time period.
