The French Van Dyro French open-door refrigerator adopts a closed design of the refrigerating compartment and the freezing compartment, and each forms an independent air-cooled refrigeration cycle system, so that the air of the refrigerating compartment and the freezing compartment do not flow with each other, that is, the air in the refrigerating compartment does not enter the freezing compartment. The air in the freezer does not enter the refrigerating room, and it is independent and fresh.
The beautiful refrigerator has a large capacity of 570L, which can meet the needs of storing a large amount of fresh food, as well as cold homemade ice cubes. The "large space" allows you to allocate your freezer space reasonably. Midea's refrigerator has an "insurance system" that breaks the limitations of traditional refrigerators and room temperature control "passive preservation", through UV-LED pesticide degradation, negative ion preservation magic pad, photosynthetic preservation technology, VC freshening technology, new generation classification and preservation technology, The six magic weapons of the fresh intelligent central processor cast the all-purpose fresh-keeping refrigerator. Midea's door-to-door refrigerators are equipped with independent temperature-controlled greenhouses in the cold room to achieve a three-speed adjustment option from 0 °C to 5 °C, which can be used for special temperature control and preservation of cooked food.
With the leading double-cycle refrigeration system, Midea's French-style French-style door-to-door refrigerator fully locks the moisture of the food, and maximizes the freshness preservation effect, bringing consumers high-quality foods that leave only fresh and no odor.
The US refrigerator adopts a closed design of the refrigerating compartment and the freezing compartment, and each forms an independent air-cooled refrigeration cycle system to ensure that the air in the refrigerating compartment does not enter the freezing compartment, and the air in the freezing compartment does not enter the refrigerating compartment. The high-humidity double-cooling tree technology benchmark, the US refrigerator adopts the independent refrigeration system of the refrigerating room and the freezing room, realizes the independent and precise temperature control of the double-refrigeration system, keeps the humidity of the refrigerating room up to 80%, locks the water and keeps fresh, and does not need plastic wrap. The effect of "moisturizing and freshening".
When the semiconductor diode is turned on, it is equivalent to the switch closing (circuit is turned on), and when it is turned off, it is equivalent to the switch opening (circuit cut), so the diode can be used for switching, and the commonly used model is 1N4148. Since the semiconductor diode has a unidirectional conduction characteristic, the PN junction is turned on under a positive bias, and the resistance in the on state is small, about several tens to several hundreds of ohms; in the reverse bias, it is off. The resistance is very large. Generally, the silicon diode is above 10 Μ Ω, and the bismuth tube is also several tens of kilo ohms to several hundred kilo ohms. With this feature, the diode will act as a control for the current to turn on or off in the circuit, making it an ideal electronic switch.
