With the continuous improvement of living conditions, more and more people are not satisfied with the capacity of the refrigerator. For boys, they may not want to go to the supermarket again and again, and like to store food at once; for girls, the refrigerator can also put many other things, such as facial masks, eye patches, etc.; for a family For those families with a large population, it is purely because of the large population that there is no food in the refrigerator. Therefore, big size freezer has a place in the market once it is born because of its capacity advantages. Today, let’s talk about inverter refrigerators?
The frequency conversion refrigerator adopts the most advanced DC ste-pless frequency conversion technology in the world, and the compressor speed can be flexibly changed in the interval according to the outside temperature change and the food storage situation. The smooth frequency conversion can avoid energy waste, save more than 70% energy than ordinary refrigerators, reduce the noise value by more than 50%, and extend the service life of the compressor and the entire machine system.

Freezer is another name for refrigerator and freezer. All evaporating tubes of high-quality refrigerators are made of high-quality copper coils and processed into wide-faced special shapes. The surface of the stainless steel plate is smooth and clean, and the thickness of the whole plate is uniform. The use of an appropriate thickness not only ensures a long service life, but also makes the appearance of the refrigerator flat and strong. Copper pipes have better cooling effect and better corrosion resistance than aluminum pipes or composite pipes. High-quality copper coils have the advantages of higher cleanliness in the pipes and fewer pipe joints, which can effectively prevent leakage or blockage in the refrigeration system. The circular tube is processed into a rectangle, so that the contact between the evaporation tube and the cold transfer liner changes from point contact to surface contact, which enlarges the transfer area and speeds up the cooling speed. However, the size of china freezer is still not as large as that of Western countries.
However, energy saving and environmental protection is the most popular theme at the moment. Under this theme, solar dc freezer were born. The size of the space is appropriate and will not cause unnecessary waste. After all, the size of the space has a certain relationship with the issue of electricity consumption. Moreover, the conversion of solar energy into electric energy greatly saves the waste of resources.

Among our natural resources, water and the sun are our common natural resources. We need water every day, and then the sun. When it’s sunny, we can use solar energy to dry clothes and so on, and solar energy is our There are really many uses in daily life. For example, the most familiar solar water heater uses solar energy to convert heat and electricity to produce hot water. Now, with the Solar DC Freezer , it can make us more energy-saving when using the refrigerator. So how does solar energy realize electricity conversion?
Solar semiconductor refrigeration. Solar semi-conductor refrigeration is a special refrigeration method that uses electric energy generated by solar cells to supply semi-conductor refrigeration devices to realize heat transfer. The theoretical basis of semi-conductor refrigeration is the thermoelectric effect of solids, that is, when direct current passes through a circuit composed of two different conductive materials, heat absorption or exotherm will occur at the junction. How to improve the performance of materials and find more ideal materials has become an important issue for solar semiconductor refrigeration. Solar semiconductor refrigeration is widely used as a cooler for electronic devices and instruments in the fields of national defense, scientific research, medical and health, or used in low-temperature measuring instruments and equipment, or making small thermostats. At present, the efficiency of solar semiconductor refrigeration devices is still relatively low. The COP is generally about 0.2 to 0.3, which is much lower than compression refrigeration.
The level of science and technology in China has been continuously improving, which has brought great convenience to people’s study and life. In recent years, the development of China freezer is very fast, which is inseparable from the progress of science and technology in my country.

In today’s society, due to energy shortages, the theme of household appliances is basically energy conservation and environmental protection, energy conservation has been further developed, and various new energy-saving advanced electrical appliances have become more and more perfect. Therefore, like solar dc freezer , solar water heaters, solar lights, solar batteries, solar power generation, solar fan covers, solar electric fans, etc., more and more solar energy is converted into electricity.
Solar appliances use photovoltaic conversion devices to convert solar energy into electrical energy, and then use them to drive semiconductor refrigeration systems or conventional compression refrigeration systems to achieve refrigeration, namely photoelectric semiconductor refrigeration and photoelectric compression refrigeration. The premise of this cooling method is to convert solar energy into electricity. The key is photoelectric conversion technology, which must use photoelectric conversion receivers, namely photovoltaic cells. Its working principle is the photovoltaic effect.
Solar thermal conversion refrigeration first converts solar energy into thermal energy, and then uses thermal energy as external compensation to achieve the purpose of cooling. Light-to-heat conversion mainly realizes refrigeration from the following aspects, namely, solar absorption refrigeration, solar adsorption refrigeration, solar dehumidification refrigeration, solar vapor compression refrigeration and solar steam jet refrigeration. Among them, solar absorption refrigeration has entered the application stage, and solar absorption refrigeration is still in the experimental research stage.
With the theme of energy saving and environmental protection, the conversion of solar energy into electricity has always been a hot topic. Using solar energy can save other energy sources as much as possible, relatively speaking, it can save a lot of other energy. Some mini car freezer also use solar energy for cooling.

Regarding the use of commercial ice cream freezer , most people certainly don’t know, especially in terms of maintenance. Properly maintained commercial ice cream freezers can greatly extend their service life and reduce many unnecessary losses and troubles.
- Clean the refrigerator at least twice a year. When cleaning the refrigerator, please cut off the power first, then soak it with a soft cloth dipped in clean water or tableware cleaner, scrub gently, and then immerse it in clean water to wipe off the cleaner.
- After cleaning, insert the power plug firmly and check whether the temperature controller is set in the correct position.
- In order to prevent damage to the exterior coating of kitchen cabinets, stainless steel kitchen freezers and plastic parts in the cabinets, please do not use washing powder, decontamination powder, talcum powder, alkaline detergent, boiling water, oil, brushes, etc. to clean the refrigerator .
- Stainless steel kitchen refrigerators and kitchen refrigerators should be placed away from heat sources and direct sunlight.
- When the kitchen cabinets, stainless steel kitchen refrigerators and kitchen refrigerators are not used for a long time, please unplug the power plug and wipe the inside of the refrigerator. After the inside of the refrigerator is sufficiently dry, close the refrigerator door.
- Pay attention to prevent the kitchen cabinets and stainless steel kitchen refrigerators from producing peculiar smell. If they produce peculiar smell, they should be removed in time. When stainless steel kitchen refrigerators and kitchen refrigerators become dirty, they should be taken out and cleaned with water or detergent. The surface of electrical parts should be wiped with a dry cloth.
- Pay attention to the movement angle when carrying.
The same is true for household top open door freezer . Whether it is sports or maintenance issues, it needs to be done from time to time. This can reduce a lot of trouble and extend the life of the refrigerator.

China has been a country with vast land and abundant resources since ancient times. Whether it is land area, GDP or population, it is a big country in the world. But many people should know that most refrigerators in China are relatively small compared to foreign refrigerators. Even big size freezer cannot be compared with large foreign refrigerators. So why are foreign refrigerators much larger than ours?
First of all, it must be eating habits. Unlike China, most Western countries focus on balanced nutrition. Daily intake of a certain amount of calories, vitamins, etc., while most parts of our country pay attention to color, aroma and taste. Chinese people pay great attention to diet, and diet is the most important thing. This sentence is not useless. Foreign countries like to order a variety of vegetables, meat and bread, while the Chinese are more sophisticated and like to use ingredients to satisfy their taste buds. Therefore, in this regard, although the Chinese have a certain demand for refrigerator capacity, they still cannot match it. There is a great demand for refrigerator capacity abroad. Moreover, compared with capacity, the Chinese will pay more attention to protection effects and energy saving instead of blindly pursuing capacity.
The second point is travel conditions. Due to the long travel distance, foreign countries need to store food for more than three days, travel is convenient and can accommodate more food, so a large capacity refrigerator is needed. In China, because the travel distance is relatively short, and the dishes are hardly sampled every day, the travel tools are relatively simple, so the requirements for the capacity of the refrigerator are not very high.
Therefore, the internal capacity of refrigerators we see in china refrigerator manufacturer or factory will hardly be too large. Even large refrigerators have a slightly larger capacity than ordinary refrigerators.

The DC power supply used by the DC freezer and the AC power supply used by the AC freezer are two different currents, but they can work in most electrical appliances. We all know that although these two currents differ by only one word, their functions are different. So, what is the difference between the two current directions?
There are two directions for alternating current. It flows out and then flows back. The amplitude is constantly changing (the law of lighting electricity changes is sinusoidal). Frequency can indicate the speed at which the AC direction changes, and phase can indicate the start time of AC transmission. Therefore, in electricity, amplitude, frequency and phase are called the three elements of alternating current, which is really good. Only when these three factors are mentioned at the same time can the characteristics of alternating current be clearly explained.
Direct current has only one direction, that is, current can only flow from positive to negative. Its size is stable. Since the amplitude and direction are unchanged, the frequency and phase are not discussed. It seems that DC is relatively simple, haha. Voltage is characteristic of AC and DC. The DC power source is not necessarily a low voltage, such as a high voltage DC power transmission system.
We only use two types of electricity, namely alternating current and direct current. Of course, direct current refrigerators use direct current, while Top Open Door Freezer use alternating current.

The horizontal Top Open Door Freezer is a very popular refrigeration equipment, especially for housewives, especially this type of refrigerator. The most important reason may be that the horizontal top-opening refrigerator has a stylish and exquisite design, fast cooling speed, high efficiency, sufficient cooling capacity and large enough volume.
The unique design of the horizontal top-opening freezer. The horizontal top-opening refrigerator has a compact structure and reduces the occupation. It adopts a wide climatic zone design to meet different environmental needs; it adopts an ultra-fine cell foam layer, which has good heat insulation effect and cold chain loss. Reduced evaporation area, high cooling efficiency, fast speed, even if it is frequently opened, there is no need to worry about food melting and “cold drinks are not cold” phenomenon; the product configuration is also very high, according to energy-saving theory and system, the commercial brand high-efficiency compressor has been optimized. This design can not only meet the needs of refrigerated food, but also prevent the loss of food nutrients and keep the color and taste unchanged. In terms of design, it embodies the concept of humanization and convenience; the bottom of the freezer is equipped with a drain pipe, which makes it easier to drain and clean. The use of the basket structure can sort and display food, and it is very convenient to enter and exit.
Of course, in addition to open-top refrigerators in bedrooms, refrigerators such as DC freezer is also very popular and favored by people.

Refrigerators such as 12V DC freezers and Solar DC Freezers have the word DC written. I believe everyone knows about AC and DC when buying electrical appliances, so they are not too unfamiliar. And everyone knows that AC is different from DC, and what we know most is that AC is alternating current and DC is direct current. So apart from that, do you know the difference between these two different currents? Let us take a look at it.
- The two polarities are called differently.
AC can be called neutral and live. DC is called positive and negative.
- The wiring during input is different.
For AC input, the wiring can be polarized. For DC input, the wiring must distinguish between positive and negative.
- The difference in frequency.
AC power parameters need to specify the frequency, such as 50Hz. DC power supplies generally do not have frequency parameters for reference.
- The relationship between current direction and time is different.
The direction of AC current is alternately changed according to the natural period. The direction of DC current flowing from the positive electrode to the negative electrode is constant and does not change.
AC and DC parameters that are often encountered in daily life.
AC power supply:
- The most common is the power supply of home appliances, the parameters are: 220V, 50Hz.
- Industrial electricity, the parameters are: 380V, 50Hz.
DC power supply:
1, No. 7 dry battery: 1.5V.
- Car battery: 12V.
- Battery car battery: 48V, 60V and 72V, etc.
- Mobile phone lithium battery: 3.7V.
- Mobile phone charger output: 5V or 5.2V.

As the concept of environmental protection continues to be known, energy-saving appliances are becoming more and more popular among consumers. The Solar DC Freezer is one of the more popular refrigerators. The first thing we need to know when purchasing is what a real energy-saving refrigerator is. Then, we need to pay attention to the following points:
The first is of course the preservation function. As consumers continue to pay attention to the issue of food hygiene, the first thing customers look at when choosing products is preservation. The refrigerator with strong preservation function can naturally keep food fresh for a long time. In order to meet the needs of customers, pay special attention to its preservation function when buying a refrigerator. With the current technology, the best fresh-keeping technique is computer temperature control. The entire process uses computers to complete dual temperature and dual control, which truly ensures that the refrigerator always adheres to a constant high temperature environment and adheres to the novelty and nutrients of the food. To ensure the freshness of the food, the second thing is the appearance. After all, everyone likes beautiful things, so I won’t say more about appearance here. After all, everyone has different aesthetics.
Then there is the cooling method. There are three main types of refrigeration methods for refrigerators: direct cooling, air cooling, and direct cooling air cooling. You can choose according to your needs.
The second key to buying a refrigerator is the quality. When we choose a refrigerator, we always have a long-term use plan, so it is very important to choose a good quality and durable refrigerator.
The last is reasonable low energy consumption. The energy consumption of refrigerators has aroused widespread concern, but it is not that the lower the energy consumption, the better. In order to achieve the purpose of energy saving, some manufacturers only adopt increasing insulation layers or adopt new techniques, but such energy saving is at the cost of increasing prices. The same function will be affected to some extent. In fact, energy saving requires not only the improvement of the product structure, but also the careful design and matching of the core component compressor unit.
