Does a fan actually cool the room?

Fans don't make a room any cooler, they merely make you feel cooler. By moving air over your skin, a fan can lower your body temperature, but will do nothing for the heat inside a room. So if you're not in the room, you're just wasting energy by leaving the fan on.

Also question is, do fans actually cool down a room?

All the electricity that is driving the fan turns directly into heat. So a fan does not cool the room at all. By blowing air around, the fan makes it easier for the air to evaporate sweat from your skin, which is how you eliminate body heat. The more evaporation, the cooler you feel.

Secondly, how does a fan cool down air? A fan, or a breeze, helps by replacing this hot, humid air with cooler, drier air that allows for more evaporation. Similarly, even without sweat, our body loses heat to the surrounding air simply by convection. If our internal temperature is higher than that of the surrounding air, energy—and thus heat—is transferred.

Beside this, how many degrees can a fan cool a room?
