In summer, the essential cool artifacts of every household are, of course, the refrigerator. I don't know if you have heard such a statement. The more things you put in the refrigerator, the more power you consume. Is this true? What should be done to make the refrigerator in the home more efficient in normal use? What about electricity?
The reporter interviewed several Dongying citizens randomly with questions. "Is the refrigerator in my home as long as it is open, it should be very power-hungry? I think it is definitely more and more power-consuming things." Mr. Zheng said.
"I think the more refrigerators should be put more electricity, the more refrigerators need more refrigeration, so that the things inside are cooler, so it costs more." Mr. Guo said.
Later, the reporter interviewed several citizens. Everyone agreed that the more things in the refrigerator, the more power they consume. But the fact is that the bigger the refrigerator is, the more electricity it costs! Obviously, contrary to what we have been interviewed by the citizens, why is this?
The reporter learned from the teacher of the third middle school of Dongying City, Mr. Zhao, that when the refrigerator is in use, the more food is put in, the more energy is saved, because the more food is put, the fewer times the compressor starts and stops, and each time The start-up of the compressor consumes a lot of power, so if we can reduce the number of times the compressor is turned on and off, it can save power. At the same time, Teacher Zhao suggested that when the refrigerator is actually used, it is most suitable for loading 60%.
Then, if the refrigerator does not have so many things to put, what should I do if I don’t have six or seventy percent?
Teacher Zhao said: "You can put bottled water in the refrigerator. The bottled water not only occupies a large area, but also has a larger specific heat capacity. It can adjust the internal temperature of the refrigerator very well. If the refrigerator at home is only empty for a short time, you can choose a foam box. , closed plastic boxes, or packed paper towels, which do not absorb heat themselves and do not consume the energy of the refrigerator."
At the same time, relevant professionals said that in addition to the amount of things placed, the location of the refrigerator will also affect the power consumption. It is best to keep the refrigerator in a cool, ventilated place, avoid direct sunlight and keep away from heat. Because the refrigerator itself is a heat-dissipating device, if the ambient temperature of the refrigerator is too high, it will consume more power.
In actual use, when the ambient temperature reaches 32 ° C, the power consumption of the refrigerator is about twice that of 25 ° C, and the power consumption of the ambient temperature of 30 ° C is 1.6-1.8 times that of 25 ° C. Experts tell us that there are some small coups that can also help your refrigerator save energy.
1. Hot food should not be placed directly in the refrigerator. It is best to put it in after cooling.
2. Dry food is more energy efficient than moist food. If you put food with high water content, it is best to pack it like vegetables and fruits, and then put it in the refrigerator.
Little friends, do you remember the way to use the refrigerator energy-saving? Act now!
Coin/Button Cell-retainers And Contacts
Antenk coin cell battery retainers Designed for memory back-up and stand-by applications, these contacts permit quick and easy coin cell replacement and installation. Eliminating "soldered-in" cells, computer, video, telecommunication and similar PCB based product users now have a reliable, "no tools required" method for changing batteries.
Extremely economical, these retainer contacts are available in surface mount (SMT) or thru hole mount (THM) styles for 4.8mm, 6.8mm, 11.6mm,12mm, 16mm, 20mm, 23mm and 24mm coin cells. The THM version has stable mounting legs for excellent board retention during wave solder. The SMT version includes a unique solder tail "flow-hole" design to bolster reflow and strengthen solder joints. They are manufactured from phosphor bronze, precision stamped and are plated with either a high luster nickel finish or matte tin finish ideal for low temperature soldering enviornments. Both feature dual spring contacts to assure reliable connections and a low contact resistance.
Antenk Coin/Button Cell-retainers And Contacts
Coin cell retainers are simple metal contacts that both electrically connect coin cells and hold them in place, while taking up minimal additional space on the PCB. They feature nickel-plating, and since most coin cells have nickel shells this helps to prevent galvanic corrosion, an electrochemical process that can damage dissimilar metals that are in electrical contact. Our retainers are always designed with automation in mind, and can be easily picked and placed, with both through hole and surface mount retainers available for most coin cell sizes. Combining the ease of automation with the low cost of Antenk's retainers, it is no wonder they are such a popular product.
