Volume
The volume of the working chamber of the car refrigerator. The larger the volume, the more products can be loaded into the unit at a time. When choosing according to this parameter, it makes sense to select a model with a margin, because it is not recommended to load products too tightly — this adversely affects the quality of the device. On the other hand, note that the volumetric container and dimensions will have the appropriate ones.
Number of chambers
The presence in the refrigerator of separate zones for storing products, separated by a stationary dense wall of a non-removable structure. The vast majority of car refrigerators have a
single-chamber layout, however, there are also
two-chamber models, which is extremely convenient for sorting products.
Removable partition
A removable partition divides the main slot of the car refrigerator into two parts (the same or different in size). The division of the internal space will come in handy in order to sort products that are incompatible with each other (for example, meat and desserts, fish and vegetables).
Max. cooling at
This parameter determines how many degrees the refrigerator is able to cool the product loaded into it relative to the ambient temperature. Let's say the maximum cooling for a particular refrigerator model is 20°C; at an air temperature of +30°C, a product with the same temperature is loaded into it. Thus, the final temperature of the product will be 30 – 20 = +10 °C. In addition, it should be noted that the final temperature cannot be lower than the minimum cooling temperature (see Minimum cooling temperature)
Max. heating at
An indicator of how many degrees the refrigerator is able to heat the product placed in it relative to the ambient temperature (if there is a heating function). Suppose a product at a temperature of +15 °C is placed in a refrigerator with a maximum heating of 60 °C; thus, the temperature of the product at the end of heating will be 75 °C, which is more than enough for the perception of food as warm and its comfortable consumption.
