Hello everybody. From several Peltier elements you can make a simple 12 volt air conditioner for cottages or a garden house. If you apply 12 volts to the contacts and fasten the radiator with a cooler to the thermal grease on one of the sides and turn on the power, the other side will emit cold. We fasten the smaller radiator to the second side and also connect it to the power supply. It turned out a little air conditioning.
The item itself.

Power of one element is 29.61 watts

If 10 Peltier elements are glued to the radiator more .. power will increase to 290 watts
. This design is a car 12-volt refrigerator, only the refrigerator does not have a cooler in the refrigerator box. To divert warm air from the cooler, you can install this design in the window, replacing the glass with plexiglass or install it in the ventilation channel then the warm air itself will not exit the street, but the cold one will cool the room. You can also take warm air to the street with a corrugated sleeve.
