What are energy -efficient refrigerators?
Energy -efficient refrigerators are those that use less energy than comparable standard models. In the development of energy -efficient refrigerators, manufacturers focus on two primary areas: insulating and compressor technology. Although there is no generally accepted definition for what can be energy -efficient refrigerators, some receive special recognition as particularly effective.
In the United States, the Energy Star® program is to mark certain models as more efficient than the competition. Models in the United States, which are at least 20% more efficient than the average model, receive Energy Star®. Many other countries can have a similar rating for refrigerators, heaters and air conditioning.
Energy efficient refrigerators are made to keep cool air as long as possible and cheaper to cool the air. Maintaining cold air inside means that the engine must run less time and less frequently. Stop the cúnik air ool, the refrigerator manufacturers lookto several areas. Improving seals, installing better insulation and using high -quality shell materials help to create more energy -efficient refrigerators. These refrigerators also often use the latest cooling technologies. Older refrigerators require more energy because compressors are not as good as those that have been developed in recent years. In fact, there has been a major increase in the compressor efficiency in the 80s and has been improving since then.
Most of this efficiency is caused by research in hydrochlorofluorocarbon (HCF). As a by -product, compressors have become more efficient. Because of this development, the current refrigerator with Energy Star® evaluation will use up to four less energy than one of the 70 years.
Although not part of the energy star evaluation system, the size of the refrigerator is also a factor in its efficiency. Larger refrigerator will work harder,Because it will be necessary to cool a larger area. This can significantly contribute to the overall energy consumption, so the consumer should carefully consider how much size is really needed. Any area that is unnecessarily cooling is inefficiency.
In order to determine which units are energy -efficient refrigerators, the consumer should simply look for a label or ask the seller for operating costs. In most of the ads, and especially in the retail location, these refrigerators will often display energy Star® or similar logo. This is a selling point, so it is often emphasized. These refrigerators can also be more expensive to buy than less efficient models, but additional costs are likely to be compensated by energy account savings over time.
