2. Defrost when the frost layer on the evaporator surface in the refrigerator reaches more than 5 mm If the frost is too thick, it will produce great thermal resistance and increase power consumption. Always keep the back of the refrigerator clean, because the dust on the surface of the condenser and compressor will affect the heat dissipation effect.
3. Change the air in the room in advance when using the air conditioner. If you need to open a window, the gap between the windows should not exceed two centimeters. In the process of using air conditioning, we should control the opening of doors and windows as much as possible.
4. Make the color, volume and brightness level of TV feel the best, which can save 50% electricity and prolong the service life of TV. In addition, when turning on the TV, the volume should not be too high. Because every 1 watt of audio power will increase the electrical power consumption by 3-4 watts. High brightness also consumes power.
The power consumption of washing machine depends on the use time. The washing time depends on the type of clothes and the degree of dirt. Synthetic fibers and wool fabrics are generally washed for 3 to 4 minutes; Cotton and linen fabric for 6 to 8 minutes; Extremely dirty clothes 10 to 12 minutes.
