Min. cooling temperature
The minimum temperature to which the refrigerator is able to cool the product placed in it when operating in cooling mode. It should be taken into account that the minimum cooling temperature is not always achievable in fact: the actual cooling temperature depends on the ambient temperature and on the capacity of the refrigerator for maximum cooling (for more details on the calculation formula, see "Maximum cooling per (°C)"). However, this applies only to refrigerators that are not equipped with compressors (see Compressor);
compressor models are able to reach the minimum cooling temperature regardless of external conditions.
Сooling energy consumption
The power consumed by the refrigerator when operating in cooling mode. The greater this power, the more performant the refrigerator is, usually, and the less time it takes to cool the product. On the other hand, note that more power means more power consumption — which can be critical, for example, during long-term operation from a car battery (that is, when the car engine is turned off).
Supply voltage
The supply voltage for which the car refrigerator is designed. There are several standard options:
—
12 V. Standard on-board voltage for passenger cars, as well as many minibuses and light trucks. Supported by most modern car refrigerators.
—
24 V. Standard voltage of the on-board network of buses, heavy trucks and other large equipment; also found in some SUVs. Car refrigerators “only for 24 V” are practically not produced, usually, such a possibility is provided in addition to 12 V.
—
230 V. Powered by a standard household outlet. It is usually a fallback option in case the refrigerator needs to be turned on outside the car for a while — for example, to pre-cool before a trip. In addition, units with such a power supply can be used as an impromptu replacement for a stationary refrigerator — for example, when leaving for a country house where there is no permanent refrigerator.
Energy label
A parameter that characterizes the efficiency of energy consumption. In modern car refrigerators, there are classes from A + and above; the more “pluses” in the marking, the more economical the device.
Note that the energy class does not describe the actual power consumption, but the efficiency of the device compared to similar models. Therefore, for example, a large
built -in A++ class unit may consume more energy than a smaller A+ class
armrest refrigerator.
