Household appliances use These methods are more energy efficient


“When you live with your parents, you will have various life conflicts. The conflict is especially serious in terms of energy saving!” Ms. Wang recently couldn’t help but vomit her own feelings to friends around her, because after she had a child, she needed help from her parents. A family of three generations has lived together, and the problems that come with it are increasing, and the contradictions are becoming more and more acute. The most recent contradiction is that Ms. Wang uses microwave ovens for hot dishes, and her mother feels that microwave ovens are not only unhealthy but also costly. It is better to use gas stoves. Subsequently, the dispute between Ms. Wang and her mother was out of control, and no one could convince anyone.
In fact, because the energy-saving common sense from life experience is not necessarily accurate, with the upgrading of home appliances, the actual and imagined may be completely different.
The volume of food stored in the refrigerator is 80%. If the storage of food is too small, the heat capacity will be reduced. If the storage is too dense, it will not be conducive to the circulation of cold air, which will increase the running time of the compressor. When placing the refrigerator, there should be a gap between the back and the wall, which can save 20% energy per day than close to the wall.
2. Energy saving lamp
Energy-saving lamps are three times more efficient than incandescent lamps and have a lifespan of nine times. Calculated by daily lighting for 5 hours, each energy-saving lamp can save 70 kWh of electricity per year, calculated at 0.61 yuan per kWh, saving 42.70 yuan a year.
3. Rice cooker
Soak the raw rice for 20 minutes before cooking to shorten the cooking time. Use the rice cooker to cook the same amount of rice. The 700-watt rice cooker saves time and electricity compared to the 500-watt rice cooker. Do not use the rice cooker for 2 hours.
4. Microwave oven
Microwave ovens are more environmentally friendly and energy efficient than gas. The biggest advantage of microwave heating is that it only heats foods containing moisture and grease, without heating the air and the container itself. The heating comparison test of the same weight of food showed that the microwave oven was 65% more energy efficient than the electric furnace and 40% more energy efficient than the gas.
5. Washing machine
Choosing "strong wash" when washing clothes in summer actually saves electricity than "weak wash". Because in the same washing time, "weak wash" changes the number of times the motor rotates more, and the instantaneous current when the motor starts is about 6 times of the normal working rated current, so the more the motor changes the direction of rotation, the larger the instantaneous start. The current causes a loss of electrical energy and wastes electrical energy.
6. Air conditioning
When air conditioning is used in summer, the air conditioning height should be lowered and the air outlet should be facing down. Because the cold air is going to fall, it always sinks in the lower part of the room, and the more electricity is saved. At the same time, the air outlet should be kept smooth. Do not stack the enlarged pieces of furniture to block heat dissipation and increase unnecessary power consumption. The energy-saving mode of using air conditioners in summer is the separate use of the functions of “air-conditioning” and “dehumidification”. It is not possible to simply compare the cost of air conditioning and dehumidification, and it can save electricity by using it separately.
7. Drinking fountain
When the water dispenser is idle, it should be powered off. The water dispenser is idle for nearly two-thirds of the day, and the electricity consumption is wasted. When the water dispenser is idle, the power is turned off, and each unit can save 366 degrees per year, which is equivalent to reducing the emission of carbon dioxide by 351 kilograms.
8. Electric fan
Generally, the fan with large fan blades has large electric power and consumes a lot of electric energy. The power consumption of the electric fan is proportional to the rotational speed of the fan blade. The 400 mm electric fan consumes 60 W when using the quick gear, and uses the slow gear. 40W. The fastest power of the same electric fan is 40% different from the power consumption of the slowest gear. Usually, the quick gear is turned on first, and the slow gear is used after cooling down, so that the power consumption of the electric fan can be reduced.
9. Range hood
Range hoods generally use a lot of grease for a period of time. If improperly cleaned, it may cause increased power consumption when continuing to use. Frequent removal and washing will cause deformation of parts, which will increase the resistance and increase the power consumption. The fumes will not enter the motor and the surface will be wiped. Do not wipe the blades while cleaning, spray the detergent to dry, so as to avoid deformation of the blades to increase resistance. In addition, do not use the range hood as a wind changer to turn on the range hood when there is soot. Chengdu Business Daily reporter Guo Jingjing
