| You have probably seen a black box at the back part | | | | This type of AC compressor was first discovered |
| of your air conditioner and this is called a scroll | | | | during the early 20th century but was developed into |
| compressor. The term 'black box' is not a technical | | | | the current model that we are familiar of today only |
| term because they just refer to the black casing. This | | | | during the late 60's. Scroll compressors are known to |

| compressors. They are smaller than the previous | | | | are reciprocating. Even though piston compressors and |
| machines that came before them. | | | | scroll compressors are very similar to one another, the |
| When you see this AC compressor in the air | | | | cooling system for a scroll compressor is much more |

| two spirals. The first spiral is stationary while the | | | | people still prefer these scroll compressors over the |
| second spiral is the one rotating around the stationary | | | | piston because people feel that they are getting more |
| spiral that traps the refrigerant gas. The process of | | | | benefits from them. |
| compression in this air conditioner compressor happens | | | | But even with the numerous advantages that these |
| due to the quick reduction of the gas that sweeps | | | | scroll compressors bring to the users, the |
