Environmentally friendly air conditioner

There are always some whimsy in my head in the environmental protection air conditioner, so I was "sealed" by my father and mother as "thinking."
Every summer, all the air conditioners will cool out the air while keeping the room cool. Coupled with the hot and natural climate, every time you go out, you will feel breathless, and today, when the earth is very scarce, we should also Save electricity! In order to solve the above problems, I am thinking about two environmentally-friendly and energy-saving air conditioners for everyone.
Dust-powered air conditioner: This air conditioner has the same shape as a normal air conditioner, but it is equipped with a small vacuum cleaner. Next to this small vacuum cleaner, a dust separator is installed to separate dust and air, and fresh air is added. Discharged and dust recovered. This air is fresh and cool, and it does not require electricity, saving energy and protecting the environment.
Carbon dioxide power generation air conditioner: This air conditioner should be installed outside the house. It absorbs a lot of carbon dioxide, then converts the carbon dioxide into a coolant through a carbon dioxide compressor, and cools the hot air through a small air cooler to let it out, so that people walking outside can feel the coolness of the summer.
These two kinds of air conditioners are the environmentally friendly air conditioners I want to invent, and maybe a similar air conditioner will appear in your home in a few years.
