The refrigerator is one of the biggest electrical appliances in the home, and it can be said that it is a big power consumer in the home. If you don't know the characteristics of this guy, you will waste a lot of electricity.
the food in the refrigerator is not too full. Because the power consumption of the refrigerator is directly related to the amount of food it contains, the more things it contains, the greater the load of the refrigerator and the more electricity it consumes. Moreover, there should be gaps between foods to facilitate cold air convection, speed up cooling and achieve the purpose of saving electricity.
The refrigerator needs to control the temperature of a small environment of less than one cubic meter, while the air conditioner needs to maintain the temperature of a large space of dozens of cubic meters, so it consumes much more energy. How can we enjoy coolness and save electricity to the maximum in hot summer?
after the air conditioner is used for a period of time, a lot of dust will accumulate on the filter screen. These dirt block the air circulation, prevent the cold air from blowing out, and the cooling effect is poor. In this case, if the indoor temperature is to drop, the compressor will have to work longer and consume electricity. Therefore, cleaning the dust screen regularly can save about 31% electricity.
in addition, the lower the temperature is set, the longer the air conditioner must run to reach this temperature, and the more electricity it consumes. Therefore, raising the refrigeration temperature of the air conditioner by 1 degrees Celsius can save more than 11% of electricity, and our bodies can hardly detect such a small temperature difference.
in fact, how to reduce the energy consumption of electrical appliances is also a problem that researchers have been exploring. An air conditioner without using traditional freon as refrigerant has been developed, which not only has high refrigeration efficiency, but also consumes less electricity. There is also an air conditioner without electricity, which can convert solar energy into electric energy for air conditioning operation. Although new and more energy-saving appliances are constantly emerging, it is most important for all of us to start from the small things around us and develop the habit of saving electricity.
In China's cities, especially large and medium-sized cities, water shortage is also an embarrassing problem that people face. China's per capita water resources is only a quarter of the world average, but its water consumption is huge. Like Beijing, the per capita water consumption is four times the world average. Therefore, don't think that saving water has nothing to do with you. A dripping faucet can miss 71 liters of water a day, which is 25 tons of water a year. In our life, such loopholes are not uncommon. Besides setting up water-saving consciousness, what other tricks can we use to save water?
in fact, as long as we pay attention to the little things around us, it is easy to save water. For example, when removing heavy oil stains from tableware, don't wash it directly with detergent. Wipe it with paper first and then clean it, which can save more than half of the water.
When washing hands, washing in a basin is more water-saving than using long-running water, and the same is true when washing vegetables, fruits or dishes. It takes a lot of water to wash continuously with the tap on, but it can be saved by intermittent washing. Save the used water and reuse it.
The water consumption of washing machines at home is large. In order to save water, manufacturers and researchers have made great efforts to save water as much as possible on the premise of ensuring clean clothes.
This inclined shape is not for beauty or originality. The design of 11-degree inclined plane has its own reasons. After the washing drum is tilted by 11 degrees, its water level is relatively deep, which can achieve a large amount of washing effect. So it saves water.
The program set by the washing machine is generally one washing and two rinsing, and water is mainly spent on rinsing. If you don't use washing powder, won't you save rinsing water?
This ultrasonic washing machine can send out 21,111 shock waves per second, which can "shake" dirt off clothes. A special water electrolysis device is also installed in the washing machine, which can decompose water molecules in tap water into hydrogen ions and oxygen ions, and use the decomposition and adsorption of ions on stains and dust to clean clothes. Taking a two-pronged approach, this washing machine without washing powder saves more than 31% water than ordinary washing machines.
and don't set the water level of the washing machine too high, otherwise there will be no friction between clothes, and it will waste water if it is not cleaned.
In addition to washing machines, toilets are also big users of water in families, accounting for about 35% of residents' water consumption. A family of three will wash away more than 3,111 liters of water a month.
technicians have developed a new type of toilet, which uses only 4 liters of water each time, saving one-third to one-half of the water compared with the existing toilet.
Its water tank is filled with water while storing air. The pressure in the water supply pipeline is used to compress the air stored inside, and then the water is pushed into the bedpan at a high speed. Different from the "pull" force of traditional sanitary ware, this new sanitary ware uses "push" force to discharge dirt, which has great impulse, so it can save water.
In fact, other domestic water in the family can also be used to flush the toilet. For example, after the last rinse, the clothes are cleaned, and the water discharged from the washing machine looks relatively clean. It is a pity that it flows directly into the sewer pipe. There is also water like washing face and vegetables, and it would be nice if it could be reused. Wu Hanping, an amateur inventor, developed a set of domestic water reuse device and obtained a national patent. He connected the sink in the kitchen, the basin in the bathroom and the water tank in the toilet to a water storage tank. Clean water from the sink and basin enters the water storage tank for toilet flushing.
In short, saving water and electricity resources in the family can not only rely on the support of new technologies and new products developed by scientific researchers, but also require each of us to start from scratch. Simple and seemingly insignificant practices can actually play a big role. Don't underestimate these efforts, and your contribution to everyone is included.
