Simple air conditioning for a summer residence


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.


Warm air.

Cold air.


Power of one element is 29.61 watts

Room temperature



Temperature at the exit of cold air.


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.

There are ready-made units for cars, they perfectly cool the cabin with two drivers.

this homemade impossible.
In this case, the use of Peltier elements is not justified. Their efficiency and performance are extremely low. It's one thing in a car refrigerator a tiny, well-insulated space ... In which the product is recommended to be laid already cooled, and the unit not only cools, but maintains its temperature. Another thing is to cool the room in which such a "heat generator" as a person sits.
