1. Keep away from heat sources and keep a gap. When the temperature around the refrigerator rises by 5℃, the power consumption inside the refrigerator will increase by 25%. Therefore, it should be placed as far away from the heat source as possible, and it is best to put it in a ventilated and cool place. Don't put hot food directly in the refrigerator until it reaches room temperature. It is best to pack the food in the freezer in plastic bags, so that it can be quickly frozen and not easily dried to prevent the water from turning into frost. Food should not be too full, and there should be a gap between it and the refrigerator wall to facilitate the circulation of cold air; Frozen food, it is best to transfer it to the freezer in a planned way before eating.
2. Don't open the door frequently. If you open the door too frequently, on the one hand, it will obviously increase the power consumption of the refrigerator, and at the same time it will reduce the service life of the refrigerator. Because the door of the refrigerator is relatively large, if the door is opened frequently, the cold air inside the refrigerator will overflow, and the warm and humid air outside the refrigerator will take the opportunity to enter, raising the temperature inside the refrigerator. At the same time, the humid air entering the box is easy to accelerate the frosting on the evaporator surface and thicken the frosting layer. Because the thermal conductivity of frost is much smaller than that of evaporator material, it is not conducive to heat conduction, which leads to slow temperature drop in the box, long working time of compressor, accelerated wear and increased power consumption. If the thickness of frost layer on the evaporator surface is greater than 10 mm, the heat transfer efficiency will decrease by more than 30%, resulting in a significant decrease in refrigeration efficiency. In addition, turning on the lighting in the box when opening the door consumes both electricity and heat, which is obviously not conducive to energy saving.
3. Power failure to keep fresh and use electricity during off-peak hours. If you are worried about the "power shortage" caused by the peak power consumption, I suggest you use a refrigerator with the function of "time-sharing power failure to keep fresh". This kind of refrigerator can keep cool and fresh even if the power is cut off for 20 hours. Moreover, its "time-sharing" function can avoid refrigeration during peak hours when electricity prices are expensive, and automatically realize "off-peak electricity consumption".
Take Beijing as an example. If the electricity price from 22: 00 p.m. to 8: 00 a.m. is 1/4 of the peak electricity price, consumers can input the information of the trough period from 22: 00 p.m. to 8: 00 a.m. into the computer control panel of the refrigerator. In this way, the refrigeration system of the refrigerator is automatically turned on at 22 o'clock in the evening for refrigeration and refrigeration. After the electricity price rises at 8 o'clock in the morning, the micro fan is driven by the storage battery, which blows the cold energy of the cold storage to the food in the refrigerator, making full use of the low-priced low-peak electricity and avoiding the expensive peak electricity.
Energy-saving refrigerator has changed from fluorine-free to energy-saving, and the design of refrigerator is developing towards energy-saving and environmental protection. What kind of energy-saving refrigerator is the most environmentally friendly?
The first trick: catch fresh.
Although the refrigerator is no longer a simple "food freezer", its core function is to keep fresh. According to scientific analysis, to keep food fresh, on the one hand, it needs a constant temperature and a strong "freezing force" inside the refrigerator, on the other hand, it needs to keep the air in the refrigerator clean and fresh. Only with strong "freezing power" can we effectively achieve the purpose of food storage, so when purchasing refrigerators, we must raise the "freezing power" of refrigerators to a higher level.
In the control of "freezing power", most products on the market are doing well at present, especially some big brands that are good at technological breakthroughs have made their own unique characteristics. For example, the Green Diamond a++ series products launched by a certain brand adopt brand-new refrigeration technology and technology, which not only ensures the strong freezing force of 4.5 kg, but also realizes healthy preservation by being equipped with innovative functions such as "titanium light nano deodorization", "silver ion sterilization" and "7℃ fresh-keeping room".
The second measure: look at energy consumption.
The refrigerator is an out-and-out "electric tiger", and the electricity consumption accounts for more than 50% of the electricity consumption of the whole family. Therefore, it is wise to choose an energy-saving refrigerator with low power consumption to save money for you in the future. No matter how the energy consumption label is publicized, as long as the principle of "both freezing power and energy saving are indispensable" is adhered to, there is basically no problem in getting out of the fog. The so-called "freezing power and energy saving cannot be less" means that we should look at the freezing power of the refrigerator while looking at the daily power consumption of the refrigerator. Don't think that the smaller the energy consumption figure, the more energy will be saved. Only the best combination of freezing force and daily electricity consumption can really bring you "savings".
The third measure: choose the volume.
Don't underestimate the size of the refrigerator. At present, there are thousands of kinds, large and small, on the market. Don't listen to others say that buying a big one is a "bold" decision. The refrigerator is for your own use, not for others, so you'd better choose the one that suits you. For a family of three, 190~220 liters is enough. Although the large-capacity refrigerator will give you enough face from the moment of vision, its huge space and huge appetite for power consumption will bring you a lot of troubles. In addition, refrigerators, "fresh-keeping rooms" and other facilities closely related to life can not be ignored. See more, ask more and compare more when buying, adhere to the three main points of "freezing power, energy consumption and effective volume" as the basis for buying, and then make a purchase decision according to your actual needs. It won't be so difficult to buy a satisfactory energy-saving refrigerator.
Nowadays, it has become a fashion for consumers to buy green refrigerators, although the price is much higher than that of ordinary products. The so-called green refrigerator is a refrigerator that no longer uses freon as refrigerant. In this way, the destruction of ozone layer in the earth's atmosphere by freon is avoided. Therefore, in the green refrigerator, chemical gas that will not destroy the ozone layer should be used instead of freon. The best way is to find another way, simply do not need refrigerants, compressors, condensers, evaporators and so on. , and use semiconductor refrigerator to make refrigerator.
The green refrigerator using semiconductor refrigerator not only completely eliminates the source of ozone layer destruction by freon, but also has the advantages of fast refrigeration speed, small volume, no machinery and pipeline, no noise and high reliability. It can realize cooling and heating conveniently, which not only saves energy greatly, but also is very beneficial to environmental protection and has a very broad development prospect.
With the maturity of products and markets, consumers pay more and more attention to energy consumption indicators when purchasing TVs, especially in today's flat-panel TVs that tend to be large screens, energy consumption has become an important indicator for consumers to choose products.
Energy shortage has become a prominent problem that restricts China's economic development. During the peak period of electricity consumption in summer, many cities will lose power, which will cause great inconvenience to people's lives. At the same time, due to the increasing production cost, the power supply department has repeatedly proposed to the state to raise electricity prices, which makes energy saving and consumption reduction closely related to everyone and becomes the focus of the whole society.
With the rapid popularization of flat-panel TV, TV energy consumption and environmental protection are becoming the focus of consumers' attention, and people are paying more and more attention to safe, healthy and energy-saving TV products. Low-energy, electricity-saving flat-panel TV not only saves money, but also eliminates potential safety hazards. Low power consumption and less heat dissipation can not only slow down the aging speed of components and prolong the service life of products, but also reduce many potential safety hazards.
Energy-saving TV Skyworth's "energy-saving LCD" TV is based on SPP (system, screen and power supply) power-saving platform. By adopting screen changing technology, Chi Mei AGT ultra-energy-saving LCD screen, power saving and circuit optimization scheme, the whole process of LCD TV from standby to system operation is omitted, and the overall power consumption is reduced by nearly half, saving energy by more than 46%. Konka's "new high-definition products for energy-saving sports" is also the main power-saving brand, including the most energy-saving I-Sport 80 series in the industry. "Energy-saving sports HDTV" integrates three core energy-saving technologies such as Chimei AGT ultra-energy-saving LCD screen, OPC energy-saving chip and PMS power management system, which can reduce the energy consumption of the whole machine by more than 52%. The series of products launched by TCL refer to natural light technology, which is TCL's unique cutting-edge display technology, and it is also the first time that China's home appliance industry has exported its patented technology abroad. Coupled with low-loss circuit design, the energy consumption of LCD TV can be reduced by up to 54%. Hisense launched ultra-thin LED backlight LCD TV, which not only improved the picture quality, but also reduced the energy consumption by more than 30%, with a minimum power consumption of 50 watts and standby power consumption of less than 0. 1 watt. In addition, the molds are all made of materials that meet environmental protection standards, and there are no radiation, toxic and harmful substances such as lead and mercury.
With the increasing demand for environmental protection and energy saving of flat-panel TV products in the consumer market, the development of flat-panel TV technology in the future will be more environmentally friendly and energy-saving. Flat-panel TVs with high energy consumption will be gradually replaced by products with low energy consumption and environmental protection materials with the improvement of consumers' energy-saving concept.
Energy-saving of air conditioning is also highly valued by people. Air conditioning energy saving is an integral part of low-carbon life, and it has several tips.
1. Don't covet the low temperature of the air conditioner, just set the temperature appropriately. Because the air conditioner can save 20% electricity when the set temperature is 2℃ higher. For people who sit still or do light work, the acceptable indoor temperature is generally between 27℃ and 28℃.
2. The filter should be cleaned frequently. Too much dust will block the filter screen, making the air conditioner more laborious and losing unnecessary electricity.
3. Improve the maintenance structure of the room. For some rooms with poor doors and windows structure and large gaps, some emergency improvements can be made. For example, use adhesive tape to seal the window joints, stick transparent plastic film outside the glass window, use sunshade curtains, stick wooden boards or plastic boards on the indoor walls, and paint the walls with white paint to reduce the loss of cold air caused by the external walls.
4. Choose an air conditioner with moderate cooling power. The air conditioner with insufficient cooling power can not only provide sufficient cooling effect, but also shorten the service life of the air conditioner and increase the possibility of failure of the air conditioner due to long-term continuous operation. In addition, if the refrigeration power of the air conditioner is too large and the thermostat of the air conditioner is turned on and off too frequently, the compressor wear of the air conditioner will increase; At the same time, it will also increase the electricity consumption of air conditioners.
5. When the air conditioner cools, the position of the air deflector is adjusted to the horizontal direction, and the cooling effect will be better.
6. The air conditioning pipeline connecting the indoor unit and the outdoor unit is short, not bent, with good refrigeration effect and no power consumption. Even if bending is required, keep the pipeline in a horizontal position.
Environmental air conditioning: environmental air conditioning, also known as evaporative air conditioning, water-cooled air conditioning, air cooler, etc. , which is a commercial ventilation equipment using water evaporation refrigeration in recent years.
The structure of environmental protection air conditioner: the environmental protection air conditioner consists of a special paper corrugated honeycomb-shaped wet curtain with large surface area, an efficient and energy-saving fan, a water circulation system, a water supply device with a floating ball inlet valve, a water pump, a shell and electrical components.
Refrigeration principle of environmental protection air conditioner: When water evaporates, it takes away the surrounding heat, thus reducing the air temperature.
Working principle of environmental protection air conditioner: when the fan is running, negative pressure is generated in the cavity of environmental protection air conditioner, so that the air outside the machine enters the cavity through the wet curtain with strong water absorption, and the water on the wet curtain evaporates in an adiabatic state, taking away a lot of latent heat. The purified, cooled and oxygenated cold air is sent to the workshop by the fan, and the cooling effect of the workshop and workshop is achieved through continuous convection.
When the fan exhausts air, negative pressure is generated in the machine, and air passes through the wet curtain. At the same time, the water pump sends water to the water distribution pipe on the wet curtain, and the water uniformly wets the contact surface of the whole wet curtain. Moreover, the special angle of the wet curtain makes the water flow to the air inlet side, which absorbs a lot of heat in the air, cools the air passing through the wet curtain, and filters the air to make it cool, moist and fresh. Unevaporated water falls back to the chassis, forming a waterway circulation. There is a water level sensor on the chassis. When the water level drops to the set water level, the water inlet valve will automatically open to replenish water, and when the water level reaches the preset height, the water inlet valve will automatically close.
The main characteristics of environmental protection air conditioning:
1. Less investment and higher efficiency; 2. Positive pressure air supply, open use, environmental protection; 3. It can replace indoor turbid, sultry and smelly air and be discharged outside; 4. Low power consumption, each power consumption is 0.5~0.8 kWh/hour, and there is no compressor; 5. Air supply volume of each ambient air conditioner: 8000~30000 cubic meters/hour; 6. Each stream of cold air covers an area of 60~300 square meters; 7. The cooling medium is a wet curtain; 8. The price is cheap, generally accounting for only 50% of the investment cost of central air conditioning, and the power consumption is also 1/8 of that of central air conditioning.
