The principle of auto-refrigerators

Auto-cooler-choose drivers who don't want to give up the pleasure of having a fresh lunch and drink everything with a cool drink while in the road. The presence of such a device is especially important for families with young children, because not need to worry about where to get fresh food to feed the baby.

In the article we will consider in detail the design of auto-refrigerators and differences of compressor devices.

Absorption auto-cooler: working principle

Such models work in a very simple way: after the absorption process (water absorbs the refrigerant), cooling occurs. The refrigerant is welded seamless tubes. In addition, the absorption refrigerator includes itself and other elements

Heat exchanger: brings the cooling level to the required value.
Container with ammonia solution.
With reflux the ammonia-hydrogen mixture.
Evaporator.

The unit operates as follows:

a concentrated solution emits ammonia;
microdroplets of the substance go to the evaporator;
inside they are cooled, the temperature of the whole structure is reduced.

Absorption refrigerators are characterized by low power consumption, silent operation, and the ability to work in an autonomous mode. The device is considered environmentally safe. In & nbsp; average, such models serve from 20 years.

Thermoelectric auto-refrigerator: principle of operation

The principle of operation of such devices is based on the "Palette effect": they work on "temperature differences". That is, while in one part the heating occurs, in the other part, on the contrary, "cooling".

Thermoelectric devices work as follows: the capacity absorbs heat from products, the thermal module transfers this heat to the stabilizer. The coating of the construction does not give the cold a "run away" and thus the necessary temperature is maintained.

Advantages of this model:

compact size;
silent operation;
functioning in stand-alone mode.

In general, the designs are resistant to external influences, so they are ideal for transporting products in any conditions.

Advice on the use of refrigerators

Before buying, you need to decide on a place to store the structure, because it affects its size. On the size of the device is affected by the volume of refrigerating chambers, choose a rate of approximately 5L l on 1 person.

Recommendations on the choice of:

The presence of special mounts will make the unit more stable and keep it from damage.
Larger structures keep the set temperature longer.
When using any model, you need to make sure that the cover is tightly closed.
Avoid exposure to sunlight on the auto-refrigerator.

Absorption devices can also be used at home, for example, for a suburban area.

Take into account that each of the types of auto-refrigerators has its own peculiarities of operation. The choice of a particular model depends on the further terms of use. For example, for short trips it is more expedient to choose thermoelectric units.
