Absorber cool box - what is it?
If you are looking for a suitable cool box, the range on the market can sometimes be overwhelming. There are now many different types and models of cool boxes to buy. In order to find the right model for yourself, it is important to be well informed and to compare. A particularly flexible cool box is the so-called absorber cool box. But what exactly is an absorber cool box?

This type of cool box can run on both electricity and gas. It is particularly quiet and is suitable for connection to a 230 volt socket. Since it is also equipped with a 12/24 volt connection, it can also be operated in a vehicle. Therefore, it is particularly suitable for campers or caravan vacationers.
How does the cool box work?
The cool box consists of four main components:
1. the expeller
2. the absorber
3. the evaporator
4. the capacitor
The principle is similar to a cool box equipped with a compressor. However, the cooling in an absorber cool box is not done by an electronically operated compressor, but the cold is generated thermally. This is called a so-called "two-component system", which consists of a refrigerant and a solvent. Here, one liquid is finally absorbed by another liquid and then separated from one another again.
The way it works is that the solvent and refrigerant are heated in the expeller and thus separated from each other. The resulting ammonia vapor reaches the separator and is freed from the remaining solvent by the condensation there.
The vapor of the refrigerant is now cooled in the condenser. This is done by releasing the heat to the heating water. The steam liquefies. Inside the cool box there is a throttle, which ensures that the liquid refrigerant is slowed down. This leads to a reduction in pressure and temperature.
The refrigerant then reaches the evaporator. There it evaporates because air and water are supplied to it and the cooling effect occurs.
The solvent pump then returns the solution to the expeller and the cycle starts all over again.

Difference to other cool boxes
The biggest difference is that an absorber cooler can be operated not only with electricity, but also with gas. Furthermore, you can connect them in a vehicle, which is important for a camping or caravan vacation. The way they work also differs from conventional cool boxes, as the cold is generated thermally. The dual-fuel system means that no electric compressor is required. Another advantageous difference is that an absorber cool box makes almost no noise.
Advantages of an absorber cool box
Since this cool box does not require a compressor or a pump, it is maintenance-free. It regulates itself and therefore works almost without any disturbing noises. When used on vacation, this is particularly beneficial when it is supposed to run overnight. It is also very practical that you do not need a power connection. All that is needed is sufficient gas or solar energy. This makes it particularly beneficial when the outside temperature is high, as the box uses this heat to heat the system.
What do you have to consider when buying?
If you decide to buy an absorber cool box, you should think about the filling volume you need. The boxes can be bought with three different connections for the gas cartridge. There are cool boxes with piercing cartridges, with screw valve cartridges and with bayonet valve cartridges. Depending on the vehicle and location or occasion of use, you have to choose the most suitable version for yourself.
