A car refrigerator is a very convenient device, especially when it comes to a long journey or a holiday trip. Its portable cooling system helps keep cool drinks, food and perishable foods.
Before you buy a car cooler, you need to think about what it is supposed to store in it, how many people there will be reserves, and how it will be charged. The internal volume of the autorefrigerator chamber ranges from 1 to 220 liters. Especially in demand for 20-35 l., This is enough for storing food in quantities of five people, and it fits perfectly into the car. There are several types of such auto-refrigerators: compressor, thermoelectric and absorption.
Compressor auto-refrigerator (auto-freezer)
Such refrigerators work as well as stationary on the refrigerant. There is a temperature regulator and the ability to quickly cool to -18 degrees with the maintenance of this temperature. The size of the inner chamber from 20 to 250l. A refrigerator with a volume of 25-75l is sufficient for traveling, and people who are engaged in fishing and hunting choose more capacious models, since this allows for a long time to keep large catch or catch. The work of such autorefrigerators is carried out from the cigarette lighter or from the 220V mains. The disadvantages are the high cost, high weight, dependence on vibration and tilting of the case, noisy work and high energy consumption.
Thermoelectric auto-refrigerator
This car cooler is used to maintain already cold or frozen foods. The temperature in the chamber is maintained from +3 to 10 degrees, but certain models can keep the temperature below zero (-3-0 degrees). Such auto-refrigerators are equipped with a cooling thermoelement and a fan that blows warm air out, and during the cold season it is able to heat products up to 65 degrees. The internal volume of the chamber is from 0.5 to 50 liters. They are not sensitive to vibration, they work quietly and weigh little. Such refrigerators operate from the cigarette lighter, but having a network adapter, they also operate from the 220V network. There are also disadvantages: they slowly pick up the temperature, the products do not freeze and consume a lot of electricity.

In the role of the refrigerant use an aqueous solution of ammonia circulating in the system during operation of the device from electricity (car cigarette lighter, bottled gas or 220V network). The capacity of such an auto-refrigerator can be from 20 to 200 liters. It works silently and does not have moving and short-lived parts that require replacing over time. The disadvantages of these auto coolers are a lot of cost, a lot of weight, as well as their response to vibration and body inclinations (the slope should not exceed 30 degrees, otherwise the device shuts off). Electrogas auto cooler prefer, going on a long journey or a long stay in places where there is no electricity. A gas cylinder with a volume of 5 liters will provide the refrigerator with power for 230 hours.
