The frigidaire refrigerator is a refrigerator that uses the principle of generating a Peltier effect on the junction of PN-type semiconductors through direct current to achieve refrigeration. There are many types of frigidaire refrigerators, which are generally classified according to their internal cooling, shape, and cooling air.
• Internal cooling classification
• Shape classification
• Cooling air method
Internal cooling classification
First, air-conditioning forced circulation type: also known as inter-cooled (air-cooled) or frost-free refrigerator. There is a small fan in the refrigerator to force the airflow in the box, so the temperature in the box is uniform, the cooling speed is fast, and the use is convenient. However, due to the defrosting system, the power consumption is slightly larger and the manufacturing is relatively complicated. Second, air-conditioning natural convection: also known as direct cooling or frost frigidaire refrigerator. The freezing chamber is directly surrounded by an evaporator, or there is an evaporator in the freezing chamber, and another evaporator is arranged on the upper part of the refrigerating chamber, and the evaporator directly absorbs heat to cool down. This type of refrigerator has a relatively simple structure and low power consumption, but has poor temperature inefficiency and is relatively inconvenient to use. Third, the combined use of the forced circulation of cold air and natural convection: new products of this type of frigidaire refrigerator is more widely used, mainly to take into account the advantages of wind and direct cooling refrigerators at the same time.
Shape classification
First, a single-door frigidaire refrigerator: a frigidaire refrigerator with a refrigerator and a freezer combined in a box with only one door is called a single-door frigidaire refrigerator. lower. Second, double-door frigidaire refrigerator: the refrigerator compartment and the freezer compartment are separated, with two box doors, the small door above is the freezer compartment, and the door below is the refrigerator compartment. The refrigerator is complex, uses a lot of materials, and is expensive. Third, three-door frigidaire refrigerator: based on the upper and lower double-door frigidaire refrigerator, a fruit and vegetable room is added below, and after opening the door separately, it becomes a three-door frigidaire refrigerator. The three-door frigidaire refrigerator has a relatively large volume, mostly above 200L, and has 3 different temperature zones, suitable for freezing, refrigeration, fresh-keeping, and fruit and vegetable storage. Fourth, the four-door frigidaire refrigerator: The four-door frigidaire refrigerator is based on the three-door frigidaire refrigerator, adding an independent, mild temperature of 0~1 ℃ between the refrigerator room and the fruit and vegetable room, which can store fresh fish. The freezer compartment (also called the fresh-keeping compartment). The four-door frigidaire refrigeratorhas 4 temperature zones, suitable for freezing, refrigeration, fresh-keeping, and fruit and vegetable storage.
Cooling air method
Gas compression type frigidaire refrigerator: It relies on the low-boiling liquid refrigerant (such as freon R12) to absorb heat when it vaporizes to achieve the purpose of refrigeration, and then use the compressor to evaporate and compress it, and then make it release heat and liquefy, thus completing the refrigeration cycle. . Due to the theory and production technology of this frigidaire refrigerator, the technology is relatively mature and the service life is long.
Gas absorption type frigidaire refrigerator: it is powered by a heat source, commonly used as a refrigerant, hydrogen can cause liquid ammonia evaporation condition as a diffusing agent, and use ammonia, water, and hydrogen mixed solution to complete a continuous "absorption-diffusion" method of frigidaire refrigerator. Because there is no running machinery, it has no noise, simple structure, low cost, not easy to damage, and long service life. It can be heated by various heat sources such as electricity, natural gas, kerosene lamps, and solar energy to make it work.
Semiconductor-type frigidaire refrigerator: It works by using semiconductor materials to produce the Pelzhan effect, that is, using P-type semiconductors and N-type semiconductors to make galvanic couples. achieve the purpose of cooling. Compared with mechanical refrigeration, semiconductor refrigeration has the characteristics of small size, lightweight, no noise, no vibration, no wear, long life, convenient adjustment of cooling rate, and no pollution. However, due to the high price, it is not widely used.
