In philosophy, the term idea has been used to cover a range of concepts. Ideas are often construed as mental representational images; i.e., images of some object. In other contexts, ideas are taken to be concepts, although abstract concepts do not necessarily appear as images.
If you have ceiling fans, they can help you maximize your air conditioning by lowering the temperature. However, that will only work if you have the fan going in the right direction. In the summer, you want the fan to go in a counterclockwise direction, also known as the forward direction. This helps drive air down toward the room's occupants. As the moving air hits the skin, it causes it to feel cooler than it really is.
There are some exceptions that you should keep in mind when it comes to ceiling fan direction. If your ceiling fan is installed in a room with a high ceiling you still put the ceiling fan direction on clockwise or reverse motion in the winter although you should put the speed on medium or high.
