The appropriate temperature for a refrigerator is 4 degrees Celsius (39 degrees Fahrenheit) or below. It is important to maintain this temperature consistently both in summer and winter to ensure that food remains fresh and safe to consume.
During the summer months, the ambient temperature may be higher, which can affect the temperature inside the refrigerator. To compensate, it is recommended to adjust the refrigerator temperature accordingly and keep it away from heat sources such as direct sunlight, oven, or stove.
During the winter months, the ambient temperature may be lower, which can decrease the efficiency of the refrigerator. To ensure that the temperature remains constant, it is recommended not to place the refrigerator near windows, doors, or places where the temperature may fluctuate too much.
In summary, the appropriate temperature for a refrigerator at any time of the year is 4 degrees Celsius or below, and it is recommended to take measures to maintain this temperature constant, regardless of the external ambient temperature.
