Home should have a refrigerator, refrigerator is a home can not lack of electrical appliances, rare is to the day, will often use the refrigerator, now the type of refrigerator has been more and more, different brands of refrigerator have their own product characteristics, for the principle of refrigerator things everyone understands, more understanding of some knowledge in this aspect will let us in the use of the refrigerator moment more handy.
Almost every family has a refrigerator, the refrigerator is very important to us at ordinary times, if there is no refrigerator, we usually very difficult to eat some fresh food, in the time to buy a refrigerator everyone should be more understanding of the principle of the refrigerator, can better assist their own choice.
1) Compression refrigerator: This refrigerator is provided with mechanical energy by the electric motor, and works on the refrigeration system through the compressor. Refrigeration system exercise a low boiling point of refrigerant, evaporation vaporization when the principle of heat absorption. Its advantages are long life and easy to use. 91-95% of the refrigerators in Mejuku belong to this category. Today’s commonly used refrigerators use a refrigerant called R600a to act as a heat carrier, transporting the heat from the refrigerator to the outside of the refrigerator.
2) Semiconductor refrigerator: It is the exercise of PN type semiconductor, through the direct current, the principle of the Peltier effect on the node to achieve refrigeration refrigerator.
3) Chemical refrigerator: It is a refrigerator that absorbs heat strongly when some chemical substances are dissolved in water and obtains refrigeration effect.
4) electromagnetic vibration refrigerator: It is the refrigerator that uses electromagnetic vibration idea as the power to drive the compressor. Its principle and structure are the same as the basic truth of compressed refrigerator.
5) Solar refrigerator: It is the exercise of solar energy as refrigeration energy refrigerator.
6) adiabatic demagnetization refrigerating refrigerator.
7) Radiant refrigeration refrigerator.
8) Solid refrigeration refrigerator.
Mode of use
1. Household refrigerator is a wide weather belt refrigerator designed based on the large temperature difference between the south and the south. In the case of the low environmental temperature (below 10℃), please turn on the temperature compensation switch for normal use. When the ambient temperature is low, if you do not open the temperature offset switch to use, the number of compressor things will be significantly reduced or not, boot time is short, long downtime, resulting in high freezer temperature, frozen food can not be completely frozen, so you must open the temperature offset switch use. (The principle is that when the ambient temperature is below 10 degrees Celsius, you need to turn on the switch to warm the refrigerator cold room, so that the refrigerator is passive, so that the temperature of the freezer room can remain cold and icy.) Turning on the temperature offset switch does not affect the service life of the refrigerator. When the winter is over, the ambient temperature rises, the ambient temperature is higher than 15℃, please turn off the temperature offset switch, so that the compressor can be prevented from starting frequently, saving electricity.
2, the refrigerator temperature controller in the use of the process, its time and power consumption are greatly affected by the ambient temperature, so we need to choose the rest of the season to use the rest of the gear, the refrigerator temperature controller should be open low in summer and open high in winter. When the environmental temperature is high in summer, it should be used in weak gear 2 and 3. When the environmental temperature is low in winter, it should be used in strong gear 4 and 5. In summer, the ambient temperature is high (up to 30℃), if the temperature in the freezer room is hit in the strong block (4, 5), up to 18℃ below, the internal and external temperature difference is large, so the temperature in the box every drop 1℃ is very difficult, and then, through the box insulation layer and door seal the loss of air conditioning will accelerate, so the boot time is very long and the shutdown time is very short, will lead to the compressor running at high temperature for a long time, Both power consumption and easy to damage the compressor. If you change to the weak gear (2, 3), you will find that the boot time is significantly shorter, and reduce the wear of the compressor, extend the service life. In summer, when the temperature is high, the temperature control is adjusted to the weak gear. When the ambient temperature is low in winter, if the temperature controller is still adjusted to weak gear, the temperature difference between inside and outside is small, it will be difficult to start the compressor, and the refrigerator of a single refrigeration system may also show signs of freezing in the freezer.
3. The accurate setting temperature of the refrigerator cold room is set at 5-7 degrees, which can ensure the preservation effect of food and prevent the depletion of resources caused by too low temperature setting.
For the principle of the refrigerator, everyone should also be familiar with it, the principle of the refrigerator is very simple, to understand some of the principle of the refrigerator, when we buy the refrigerator can also play some role, at the same time, everyone should understand more about the use of some refrigerator, strive to extend the service life of their own home refrigerator.
