Impossible!
The main power consumption of air conditioners is the compressor, not the fan. For example, the electric fan in the house is also very powerful and consumes much less energy than the air conditioner.
In addition, using wind to generate electricity will increase the resistance of air conditioning fans and increase energy consumption. In addition, the energy conversion efficiency at this stage is very low. Car engines are hundreds of years old and their efficiency is less than 50%. Wind energy is less efficient. Your idea is unrealistic.
The first type of perpetual motion machine: a motor that consumes no energy but can produce energy continuously. For example, it generates electricity by burning hydrogen, then uses part of the electricity to produce. hydrogen and produces the remaining part.
The second type of macperpetual motion hine: consumes no energy, absorbs surrounding energy and returns it for use, for example, absorbing heat from the air to produce electricity.
The idea of a perpetual motion machine originated in India around 1200 AD, this idea spread from India to the Islamic world, and from here in the West. In Europe, the most famous perpetual motion machine design was proposed by a Frenchman named Hennecaut in the 13th century. As the picture shows: there is a rotating shaft in the center of the wheel, and 12 movable short rods are installed on the edge of the wheel. An iron ball is installed at one end of each short rod.
The system designer estimates that the ball on the right is further from the axis than the ball on the left. Therefore, the rotational torque generated by the ball on the right is greater than the rotational torque generated. by the ball on the left. In this way the wheel turnsra endlessly in the direction indicated by the arrow and will cause the machine to rotate. This design has been copied by many people in different forms, but it has never achieved continuous rotation.
If you analyze it carefully, you will find that although the torque generated by each ball on the right is large, the number of balls is small, and the torque generated by each ball on the left is small, but the number of balls is large. Therefore, the wheel will not continue to rotate and do external work, but will only swing a few times and then stop.
