When it is necessary to go on trips for a long distance or to transport perishable products, the car mini-refrigerator very much helps. In specialized stores you will be offered several types of this equipment with different types of cooling, different price categories. We suggest to understand which auto-cooler is better to choose, and how to do it correctly.
How does an automobile refrigerator work?
When driving, the car refrigerator works from the cigarette lighter. When you stop, it can work through the converter from a normal network with a voltage of 200V, as well as from any other power source.
This can be a special isometric container, bag or portable camera. If you need a short-term storage, it is enough to have a container or an isometric jar. If there is a need to keep the freshness for a longer period, an isometric container with a refrigeration unit is suitable. It can be installed both in the rear seat, and in any other suitable niche in the car. Now we will consider in more detail which auto-refrigerator to choose, depending on the features of its design and operation principle.
Autorefrigerator device
The main criterion in the distribution of species is the way that the products are cooled. By the method of cooling, three main types are distinguished: absorption, thermoelectric and compressor.
- The thermoelectric automobile refrigerator, as a rule, has a small volume. It is perfect for a family picnic for two or three people. The thermoelectric automobile refrigerator is capable of operating both in the cooling mode and in the heating mode. This kind of uneconomical, but much greener than a freon automotive refrigerator, and the design minimizes the likelihood of breakage. All these characteristics are fully reflected in the price of this type. It is lower than the price of a compressor refrigerator, and the most expensive model will cost about $ 400.
- If you need to transport more products, it is advisable to purchase an absorbent auto-refrigerator. But its disadvantage, like the first type, is inefficiency. The work is based on a water-ammonia solution: due to the absorption of ammonia water and further heating of the mixture, the refrigerant circulates. This car fridge from the cigarette lighter does not have any kind of moving parts, which makes it safe and reduces the risk of damage to a minimum, but it is sensitive to strong slopes when moving. An essential advantage is the possibility of working without electricity on liquid or gaseous fuels.
- Compression automotive refrigerator is considered to be the most economical type. Cooling is carried out due to the circulation of the refrigerant, which is provided by the compressor. But he is quite sensitive to all kinds of shocks and vibrations. The difference in energy savings significantly increases with increasing capacity
the refrigerator itself. It is best to keep the cold in the form of chests with the top cover. The cold is typed quickly enough, and the cameras are practically unlimited in size.
If economy is important to you, then pay attention to the models of electro-gas auto-refrigerators. They are capable of operating at a constant current of 12 / 24V, alternating current, and also on liquefied gas (propane / butane). The cost of such a portable car refrigerator is quite high, but in the process of operation work on gas is more economical and it pays off quite quickly.
If you are planning a not too long trip to replace the car refrigerator can be a simple refrigerator bag , which you can also do with your own hands .
