Opening the door of a refrigerator is not without consequences for the appliance. Indeed, this operation causes hot air to enter the enclosure; the cold circuit is therefore more stressed to cool the atmosphere and maintain a satisfactory temperature in the compartment. To remedy this drawback, Hisense has provided the RB390N4BC31 refrigerator with an artificial intelligence system that studies the opening times of the door over the previous 7 days in order to lower the temperature before and after this manipulation. In this way, it will have the least possible consequences on the variation of the cold in the enclosure and, ultimatelyon food preservation.
Apart from this innovation, the Hisense RB390N4BC31 is a very classic handset. In the upper part, we find the refrigerator with a volume of 204 liters in which reigns a No Frost cold which tends to dry out the food if it is not kept in suitable containers. Do not hesitate to place fruits and vegetables in the tray provided for this purpose so as not to see them wither quickly. Hisense has not seen fit to offer a drawer where the temperature is maintained above 0°C to preserve fragile products such as meat or fish without freezing and damaging them.
The freezer (96 liters) is also cooled by a cold No Frost which avoids the chore of defrosting. Indeed, the air is completely devoid of humidity and no layer of ice can form. Paradoxically, frost constitutes an insulating wall and therefore requires more effort from the various components of the refrigerator to maintain a sufficiently low temperature, leading to premature wear of parts and excessive electrical consumption. In addition to the two classic drawers, the freezer contains a retractable tray placed on telescopic rails (Easytray system).
The entire control panel is on the door of the RB390N4BC31, which allows you to adjust the temperature in the different compartments but also to activate the super freezing modes (in order to accommodate a large quantity of frozen products ) or eco; the temperature in the refrigerator reaches 6°C and -17°C in the freezer so as not to consume too much energy when the appliance is not used to its maximum capacity.
The Hisense RB390N4BC31 refrigerator is already available for 599 €, a rather reasonable price for a combined No Frost appliance.
