I don't know if you have ever thought of such a problem, in the plane, moving train and other mobile transportation, there are some need to refrigerate the preservation of food can also be provided to passengers, but these vehicles can not load our home refrigerator, so the airline or train company is using what to these foods to refrigerate preservation? In fact, electronic refrigerators play a big role in this process.
Despite the difference of only one word in the name, electronic refrigerator and refrigerator can be said to be very different in all aspects. Also known as a semiconductor refrigerator, the electronic refrigerator has been given the title of "the world's smallest compressor," and because of its small size and lack of need for mechanical refrigeration, it can be used in mobile platforms like airplanes and automobiles.
Electronic refrigerator and refrigerator in the refrigeration principle is quite different, it is through the semiconductor electronic refrigeration (also known as temperature difference electric refrigeration) for refrigerator refrigeration work. The so-called temperature difference electric refrigeration, is the use of the Peltier effect - in different materials due to the different state of electron movement, the formation of the potential is not the same, so there will be a potential difference between the two materials. And electrons in the lower energy level to the energy movement, it will release a certain amount of energy, in the work of the electronic refrigerator both performance bit heat production. On the contrary, when the electron wants to engage in energy level movement, it will absorb heat, which is manifested as a refrigeration process. In many materials, semiconductor materials can form a higher thermal potential (potential difference), so can be used to manufacture this small thermoelectric cooler and electronic refrigerator.
There is also an electronic control system that controls the temperature of the electronic refrigerator, which works around the refrigeration system. First, by detecting the temperature in the freezer, the system compares the detected temperature with the set temperature and drives the press if there is a difference between the two. After driving the press to start, the control solenoid valve can both achieve the purpose of cold storage through the action of refrigerant. When there is no need to start refrigeration, the system will determine whether there is any other command to open the press, and if not, it can drive the press to close.
Based on this working principle, electronic refrigerator solves the problem of medium pollution or mechanical vibration in the refrigeration refrigerator is difficult to solve. In addition, the electronic refrigerator also has a series of advantages such as environmental protection, energy saving, high efficiency, convenience, etc., so it has a very high development value and promotion value. If you want to install a small refrigerator in your car, you can understand the working principle of electronic refrigerator in a more comprehensive and technical parameters and then purchase, so that we can choose a perfect function, high performance of the electronic refrigerator.
