They are brown and very energy efficient.The best important is that they are quite cheap.The three door refrigerator adds a fruit and vegetable room, forming three different temperature areas, which has the functions of freezing, cold preservation and fruit and vegetable storage, with stronger independence and most of the volume above 200L.The energy-saving refrigerator adopts the advanced refrigerator compressor, the refrigeration capacity, energy efficiency ratio and other technical parameters are realized, and the thermal insulation performance of the refrigerator is enhanced, so the thermal conductivity of the whole box is better than that of the general refrigerator.The features of the variable frequency refrigerator are that the rotation speed of the refrigerator compressor is not fixed, the rotation speed is fast when the temperature is high, so as to cool down as soon as possible. When the temperature is low, the rotation speed is reduced, the existing temperature is maintained, the instantaneous pneumatic wear of the compressor is reduced, the compressor life is longer, and the refrigerator is more energy-saving.
