In the heat, the car gets so hot that not only do you not want to get in, but it is also strongly discouraged, as it is unhealthy. To cool the cabin, you need to control the air conditioner and burn fuel in vain. And if the air conditioning does not work or does not exist at all? In this case, homemade evaporators or cold accumulators will help.
Modern air conditioning systems operate on the principle of compressing and liquefying Freon, followed by evaporation and heat absorption. In addition, the car’s climate control system is quite inert. It only works at full power while driving and takes a few minutes to start blowing out cold air.
Wet evaporator
However, the interior can be cooled in other ways, including by absorbing heat from the evaporation of water. These principles formed the basis of the first air conditioning systems for buildings, which are still used in some places.
The fact is that the evaporation of water, like condensation, occurs at a stable temperature, called the “dew point”. The lower the relative humidity of the air, the lower the “dew point” will be lower than the actual temperature. For example, at a humidity of 32-37% and at a temperature of 35 ° C, the “dew point” is 10-12 degrees. When water evaporates, a significant absorption of heat is observed, cooling the air.
Even a schoolboy can make a simple vaporizer. You need to take a container, pour sawdust and fill them with water. If there is no sawdust, you can get by with rags. The main thing is that the area of the evaporation zone is larger. The sink is usually placed on the floor in front of the passenger seat. To be on the safe side, you can wipe the “torpedo” and the center console with a wet cloth. At the same time, do not forget to turn on the fan at full power and direct the air flow to the evaporator. The stronger the airflow, the more efficiently the basin works.
In the middle of the last century, special water evaporators for cars were manufactured on an industrial scale. Only their work surface was outside the cabin and blown up by oncoming streams as the car moved. The cooled air was then routed through the tubes to the interior of the vehicle.
Cold batteries
There is another interior cooling life hack related to the use of cold accumulators. These are regular plastic bottles that stay overnight in the freezer. They can be fixed anywhere on the floor, under the rear row deflectors or in cup holders, in addition, it does not hurt to install an external fan powered by the cigarette lighter. Why not a mini air conditioner? Ice melts at zero degrees, so the cooling efficiency will be even higher than that of a water evaporator.
By combining these two methods, noticeable results can be achieved. Well, you can fight the heat while driving with the help of open windows.
