26、 More Efficient A)Modern refrigerators are far more efficient than they used to be, but they still draw a lot of power often more than any other appliance in your home. If you really want to save money on your energy bill and limit your environmental impact you should probably upgrade to a more effi
27、cient model. If thats out of the question, there are steps you can take to make your existing machine more utility-friendly. Follow this guide to cut down on your fridges energy use, and save some money while youre at it. Keep It Stocked B)Empty fridge space helps no one. It looks depressing, limits
28、 your cooking options, and perhaps worst of all makes your fridge work harder to regulate temperature and humidity. The same goes for your freezer. Food and drink hangs on to cold better than air, so the more solids and liquids in your fridge, the less work it has to do to keep temperatures low. The
29、 takeaway here is simple: Keep your fridge(and freezer)stocked. If, for whatever reason, you dont have enough food to stock the whole fridge, just fill some bottles or containers with water and place them throughout the cavity. The same strategy can be used in your freezer. Just be sure to seal your
30、 containers tight to prevent excess moisture from escaping into the fridge cavity. If you can, use glass containers theyre better at retaining cold than plastic. Also, dont store your goods too close to the walls of the fridge, as you need the air to circulate to remove heat. Keep It Cool But Not To
31、o Cool C)Obviously you want your fridge to be cold(thats the whole point, isnt it?), but you dont want it to be too cold. The lower the temperature setting, the more energy the fridge has to use to maintain that temperature. The same goes for your freezer. An ideal setting is 37F for the fridge, and
32、 0F for the freezer. Anything higher is risky with regard to food preservation, and anything lower is wasteful and unnecessary. If you have an older model with a simple number dial for a regulator, you can use any old thermometer in a cup of water to monitor the temperature over time. Freezers are e
33、specially precise when it comes to temperature regulation. To prevent that dial from going wild and, in turn, ninning up your energy bill make sure there is sufficient air circulation. Youll also want to avoid holding the freezer door open while you decide what to make for dinner. This allows warm k
34、itchen air into the freezer and wastes energy. It also contributes to freezer burn another freezer-related nuisance. Vacuum the Coils D)You know those spiraling tubes(螺旋管 )at the back of your fridge? Those are condenser(冷凝器 )coils.(Newer fridges keep them hidden, but theyre still there.)Theyre where
35、 the hot, gaseous refrigerant(气态制冷剂 )becomes the cold, liquid refrigerant that absorbs heat in your fridge cavity. E)To do this, the condenser coils need proper ventilation. As dust and debris collect on the coils, it inhibits their ability to give off heat. This, in turn, forces the refrigerator to
36、 run longer cycles to ensure enough heat is being transferred. Once again, the solution is simple: Keep the condenser coils clean! First and this is very important cut off the power of the fridge. Next, simply take a vacuum to the coils, gently removing all the dust and dirt you can. You really only
37、 need to do this once a year, so make it count.(If your fridge has hidden coils, make sure to clean the area around the fridge, including underneath.) Turn off the Ice Maker F)Your fridge may be the biggest energy consumer in your kitchen, but the ice maker is the biggest energy hog in your fridge.
38、According to a 2011 study by the National Institute of Standards and Technology, a typical ice maker increases a fridges overall energy consumption by 12 to 20 percent. More recent ice makers can be a lot more efficient, but still draw additional electricity. If you find you arent using your ice mak
39、er, just turn it off. Youll save a little in the long run. This is due to the motor inside the ice maker that dumps ice into the tray. In most freezers, the device stops making ice when the tray fills up and triggers a sensing instrument. But this doesnt stop the motor from running it only stops it
40、from producing ice. To stop the motor, you have to turn off the device itself. Chances are, you bought a fridge with an ice maker because you intend to use it. But if you find that you arent using it, just turn it off. Youll save a little in the long run, and its one less thing that can break. G)Als
41、o, if you have a manually-defrosting fridge, keep an eye on the ice buildup along the walls of the freezer cavity: too much can restrict air flow and force your fridge to work harder. Manufacturers actually recommend defrosting that kind of freezer twice a year. Seal Foods to Prevent Evaporation H)Y
42、ou know those condenser coils we talked about? Well, if you follow them, youll find they eventually snake into your fridge and freezer cavities, where they absorb heat and lower the temperature. That process of heat absorption also serves to evaporate humidity. There are a couple of tips here. For o
43、ne thing, this means you shouldnt store fruits(which require moisture to prevent drying or decaying)in the main cavity. Thats what the preservation drawers are for. For another, it means excessive moisture in the fridge forces the machine to work harder to draw it out. To prevent buildup of excess m
44、oisture, you should seal leftovers and other moist foods in closed containers. Its a small but important measure if youre serious about maximizing fridge efficiency. Let Food Cool I)This one should be obvious, but well remind you anyway: Dont put hot food into your fridge. While you shouldnt let tha
45、t pot of chili sit around too long, you can wait a while for it to cool to at least room temp. Why would you do that? Because your fridge goes into overrun when it has to absorb residual heat. Its a far more pressing concern than external factors like dusty coils. Most experts recommend letting hot
46、food cool for no more than two hours before popping it in the fridge. Any longer than that could lead to contamination. Position the Fridge Correctly J)Where you put your fridge can affect how much energy it consumes. It sounds silly, but refrigerators need to breathe, and the closer they are to wal
47、ls or furniture, the harder it is for heat to escape. Unless you have a specially designed built-in model, you should make sure to leave at least two inches of space around the units frame. You should also be wary of your fridges distance to heat sources like ovens, stove tops, water heaters, and ra
48、diators. The heat that builds up around these appliances stresses the refrigerator and makes it work harder. Even direct sunlight can be taxing. 47 37F for the fridge and 0F for the freezer are the best food-preserving and the most energy-saving settings. 48 If your present fridge is not energy-savi
49、ng or environmentally friendly, here are some tips to increase its efficiency. 49 A common ice maker consumes 12 to 20 percent more of a fridges overall energy consumption. 50 To clean the condenser coils, you should first shut off the power and then vacuum them gently. 51 Empty fridge space consumes more energy to adjust temperature and humidity than a stocked one. 52 Too much frost on the walls of the freezer cavity
