Huge business opportunity! Did you not graduate from junior high school? Or a big sleep in physics class? Forgot the law of conservation of energy? The workmanship of the motor is increased. Increased power consumption. Is the overall temperature in the house only going to keep rising? The temperature of the air outlet will indeed decrease a little, but the temperature on the back will increase, and the effect of the two will be reduced. If you really want this thing to work, you have to install it in its entirety on the north (backlit) windows. Fan outdoors. The heat created by the fan is only effective when it is dissipated outdoors. (Figure 1) Of course, the temperature of this thing will definitely drop. First of all, because the wind speed compression is accelerated. Secondly, the wind direction is more concentrated, and the temperature of the air outlet drops slightly. But there will be no drop in the room temperature of the room. On the contrary, it will rise.

You said that I figured out such an invention, can a manufacturer make a batch of it? Take advantage of the heat to make a fortune. Just give me a little bit of a thank you for the invention. Last time, I invented a laptop cooling system, and many people made a lot of money on the whole network. Didn't give me a penny.
