The more people in the household, the greater the capacity required for the refrigerator. For small households of 1-2 people a refrigerator with a capacity of 200-350L is satisfactory, while for households of 3 to 4 people a refrigerator with a capacity of 350-500L is more suitable. Finally, XL refrigerators with a capacity of over 500L are ideal for large families or for those who often receive guests.

The climate class determines the temperature range within which the refrigerator operates efficiently and can properly preserve food. Climate classes include, SN (Subnormal): 10°C - 32°C, N (Normal): 16°C - 32°C, ST (Subtropical): 16°C - 38°C and T (Tropical): 16 °C - 43°C.
