Detailed Description
Embodiments of the power control platform for a refrigerator according to the present invention will be described in detail with reference to the accompanying drawings.
The power consumption of the refrigerator is increased by 25% when the temperature around the refrigerator is increased by 5 ℃. Therefore, it should be placed as far away from the heat source as possible, so as to ventilate the shady place. The hot food is not directly put into a refrigerator, and is put into the refrigerator when the temperature reaches the room temperature. The food in the freezing chamber is preferably packaged in a small bag made of plastic bags, can be frozen quickly, is not easy to dry, and is prevented from moisture becoming frost; food should not be too full, and a gap should be left between the food and the wall of the refrigerator to facilitate flowing
The frequent opening of the door can obviously increase the power consumption of the refrigerator and reduce the service life of the refrigerator. Because the door of the refrigerator is large, if the door is opened for a plurality of times, cold air in the refrigerator escapes, and warm and humid air outside the refrigerator enters the refrigerator, the temperature in the refrigerator rises. Meanwhile, the moist air entering the box can easily accelerate the frosting on the surface of the evaporator, and the frosting layer is thickened. Because the coefficient of heat conductivity of frost is much less than that of the evaporator material, it is not favorable to heat conduction, causes the temperature decline slowly in the case, and compressor operating time increases, and wearing and tearing accelerate, power consumption increases. If the thickness of the frosting layer on the surface of the evaporator is larger than 10 mm, the heat transfer efficiency is reduced by more than 30%, and the refrigeration efficiency is greatly reduced. In addition, when the door of the box is opened, the illuminating lamp in the box is turned on, so that electric energy is consumed and heat is dissipated, and obviously, energy conservation is not facilitated.
In order to overcome the defects, the invention builds a power supply control platform of the refrigerator, and can effectively solve the corresponding technical problem.
