How to save a drop of water, a piece of paper, a grain of rice, and a kilowatt hour of electricity. Collection of ideas

The refrigerator is one of the appliances that consumes the largest amount of electricity in the home. It can be said to be a major power consumer in the home. If you don't understand the characteristics of this guy, you will waste a lot of electricity.

Don’t overfill the refrigerator with food. Because the power consumption of a refrigerator is directly related to the amount of food it contains, the more food it contains, the greater the load on the refrigerator and the more electricity it consumes. There should be gaps between foods to allow cold air to circulate, speed up cooling, and save energy.

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 the coolness while maximizing energy saving in the hot summer?

After using the air conditioner for a period of time, a large amount of dust will accumulate on the filter. These dirt block the air circulation and prevent the cold air from blowing out, and the cooling effect is poor. In this case, if the indoor temperature is to be lowered, the compressor will have to work longer, which will consume electricity. Therefore, regular cleaning of the dust filter can save about 30% of electricity.

In addition, the lower the temperature is set, the longer the air conditioner must run to reach this temperature, which consumes more electricity. Therefore, raising the air conditioner cooling temperature by 1 degree Celsius can save more than 10% 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 scientific researchers have been exploring. An air conditioner that does not use traditional Freon as refrigerant has been developed. It not only has high cooling efficiency, but also consumes less power. There is also a type of air conditioner that does not require electricity, which can convert solar energy into electrical energy for the operation of the air conditioner. Although new and more energy-saving appliances are constantly emerging, it is most important for all of us to start with the little things around us and develop energy-saving habits.

In my country’s cities, especially large and medium-sized cities, water shortage is also an embarrassing problem faced by people. my country's per capita water resources are only one-quarter of the world average, but water consumption is huge. For example, Beijing's 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 leak 70 liters of water a day, which is 25 tons of water a year. Such loopholes are not uncommon in our lives. In addition to establishing awareness of water conservation, what other tips 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 on tableware, do not wash it directly with detergent. Wipe it with paper first, and then wash it. This can save more than half of the water used.

When washing hands, washing in a basin saves more water than using a long flow of water. The same is true when washing vegetables, fruits or washing dishes. Continuous rinsing with the faucet on is very water-consuming. Intermittent rinsing can save water. . Save used water and use it again.

Washing machines in homes consume a lot of water. In order to save water, manufacturers and scientific researchers have made great efforts to save water as much as possible while ensuring clean clothes.

This inclined shape is not for beauty or novelty. The 10-degree inclined plane design has its own reasons. After the washing drum is tilted 10 degrees, its water level will be relatively deeper, which can achieve the washing effect of a larger amount of water. So it saves water.

The program set by the washing machine is generally one wash and two rinses. The water is mainly consumed in rinsing. If you don’t use washing powder, wouldn’t you be able to save rinsing water?

This ultrasonic washing machine can emit 20,000 shock waves per second, which can "shock" dirt from clothes. The washing machine is also equipped with a special electrolytic water device, which can decompose water molecules in tap water into hydrogen ions and oxygen ions, and use the ions to decompose and adsorb stains and dust to clean clothes. With a two-pronged approach, this washing machine that does not use washing powder can save more than 30% of water than ordinary washing machines.

Also, don’t set the water level in the washing machine too high, otherwise there will be a lack of friction between the clothes and the clothes will not be washed clean, but water will be wasted.

In addition to washing machines, toilets are also major water users in households, accounting for about 35% of residents’ water consumption. A family of three will flush more than 3,000 liters of water a month.

Technicians have developed a new type of toilet that uses only 4 liters of water each time, saving one-third to one-half of the water than the existing toilet.

Its water tank accumulates air while filling with water. It uses the pressure in the water supply pipe to compress the air accumulated inside, and then pushes the water to flow into the toilet at a higher speed. Different from the "pull" force of traditional sanitary ware, this new type of sanitary ware uses "push" force to discharge dirt, and the impact is large, so it can save water.

In fact, other domestic water in the home can also be used to flush the toilet. For example, after the last rinse, the clothes have been washed clean, and the water discharged from the washing machine looks relatively clean and flows directly into the sewer pipe. It's a pity. It would also be nice if the water used after washing your face and washing dishes could be reused. Amateur inventor Wu Hanping developed a domestic water reuse device and obtained a national patent. He connected the kitchen sink, bathroom basin and toilet cistern to a water storage tank. The relatively clean water flowing out of the sink and basin enters the water storage tank for toilet flushing.

In short, saving water and electricity resources at home cannot only rely on the support of new technologies and new products developed by scientific researchers. It also requires each of us to start from scratch, seemingly inconspicuous and simple practices. In fact, it can play a big role. Don’t underestimate these efforts. Your contribution to everyone is contained in them.
