Car refrigerators are a thing that has not yet been appreciated by the Russians, but extremely useful. In America, one family has 2-3 mobile units for different occasions. Such devices can be extremely convenient both when leaving for the cottage, and in the caravan.
To date, several varieties of such designs are available.
Thermoelectric Models
Automobile refrigerators of this type are not at all afraid of turns and bumps. Some models function even when lying on their side or back. Another undoubted advantage is that they can work both for cooling and heating. The disadvantages include a large degree of energy consumption. Another disadvantage is inertia. The camera cools and heats up quite slowly.
Automobile refrigerators of this type operate due to the passage of electric current through semiconductor wafers installed externally and internally. The principle of operation is quite simple. When the internal elements are heated, the external ones are cooled and vice versa. As a result, an increased or decreased temperature is established inside the chamber. Typically, such models are chosen by truckers.
Absorption Equipment
The main advantage of such structures is the ability to work independently of the on-board network.
Such automobile refrigerators can operate on gas and liquid fuel. Of course, such equipment will be very useful in hiking, as well as in cottages. For example, if we talk about the average family, then to use the refrigerator for a month, a 5-liter gas cylinder is enough.
The principle of operation of such models is also nothing complicated. Cooling occurs due to the absorption of ammonia by water and heating of this mixture. The disadvantages of refrigerators of this type include sensitivity to inclines. It is necessary to handle the equipment quite carefully. However, for ordinary motorists, the purchase of such a model is likely to be the best solution.
Compressor models
Such equipment works on the same principle as the stationary models familiar to all. This car refrigerator, the price of which is quite high (700 - 2000 EUR), is used by car owners less often.
Such equipment is very sensitive to inclines and bumps. When depressurization, the refrigerant escapes to the outside. However, such models have undoubted advantages. First of all, it is economical in terms of energy consumption. In addition, such designs cool products much more efficiently than any other species and are completely inertial.
The cost of equipment and its dimensions
As mentioned above, the most expensive today are compressor models. An automobile absorber refrigerator (reviews of this equipment are extremely positive) costs slightly less (500 - 700 EUR). And the least funds will have to be spent on the purchase of a thermoelectric model (100 - 300 EUR).
As for the dimensions, the most spacious are the compressor varieties. The camera capacity of such models can range from 18 to 220 liters. The absorption structures (24 - 140 l) have slightly smaller dimensions. And the smallest cameras are equipped with thermoelectric refrigerators (0.5 - 49 l).
Thus, choosing the most suitable model should be given, first of all, your own financial capabilities. Also important is the composition of the family and how much it may be necessary to operate the unit when disconnected from the network.
