Solar energy plays a very important role in our daily lives. For us, solar energy is a very important natural energy source, giving us great convenience in life. Solar water heaters are widely used, and solar cooling is also being gradually promoted. Solar DC Freezer is the application of solar energy in refrigeration.
Its basic principle is to collect solar radiant energy and convert it into heat energy through interaction with the matter for use. Currently, the most commonly used solar collectors include four types: flat plate collectors, evacuated tube collectors, ceramic solar collectors, and focused collectors (trough, dish, and tower).
China is rich in solar energy resources, and the prospects for solar energy utilization are broad. However, natural resources are not inexhaustible, so we must use resources rationally and care for the environment. I believe that with solar energy, China freezer can be better.

Freezer can be found in many supermarkets and shopping malls. The freezer has a large storage space and a strong function, so it has always been very popular with merchants. In recent years, china freezer has also exported a lot, which shows that China’s freezer is indeed very popular.
Similar to the development of most of the home appliance industry, the growth of refrigerators is accompanied by the increase in industry concentration and the acceleration of industrial expansion. Especially since the promotion of home appliances to the countryside for two years, farmers and consumers have the opportunity and platform to directly contact the brand. Farmer consumers pay more attention to brand and quality when purchasing home appliances, and the consumption concepts of rural market consumers and distributors are becoming mature. This is also the process of collective brand recognition of Chinese consumers. With the depth of the “home appliances to the countryside” policy Promotion, coupled with the impact of “home appliances going to the countryside” on the requirements of enterprise qualifications, market distribution “increasing brand concentration” will become an inevitable trend, the influence of mainstream products will expand, sales will increase, some qualifications are poor, and power is weak Of non-mainstream brands have been marginalized, and market share has been lost seriously.
The solar dc freezer is not particularly clear to many people. The popularity is far from that of ordinary refrigerators, but it is very practical.

We all know about solar energy and of course how important it is to us. Moreover, the application of solar energy is becoming more and more widespread at present. Solar DC Freezer is one of them. Nevertheless, solar energy still has certain inconveniences for us.
The dispersion of solar energy. Although the total amount of solar radiation reaching the surface of the earth is large, the energy flow density is very low. On average, near the Tropic of Cancer, when the weather is clear in summer, the irradiance of solar radiation is the largest at noon, and the solar energy received on an area of 1 square meter perpendicular to the direction of sunlight is about 1,000W on average; The average day and night throughout the year is only about 200W. In winter, it is only half, and cloudy days are generally only about 1/5. This kind of energy flow density is very low. Therefore, when using solar energy, to obtain a certain conversion power, a set of collection and conversion equipment with a relatively large area is often required, and the cost is relatively high.
Therefore, China freezer still needs some time to make corresponding improvements.

Most of the refrigerators used in our daily life are relatively large, so it is relatively inconvenient to carry them. Summer picnics or long-distance travel can be a problem, so there is the appearance of Mini Car Freezer. mini car freezer is divided into semiconductor type and compressor type. The working principles of the two types of car refrigerators are also quite different.
Semiconductor car refrigerators are also called electronic refrigerators. Unlike traditional refrigerators that use refrigerants for cooling, the principle of semiconductor car refrigerators belongs to electronic physical cooling. This cooling method uses the “Peltier effect”. The charge carrier moves in the conductor to form a current. Because the charge carrier is at different energy levels in different materials when it moves from a high energy level to a low energy level, it will Excess heat is released. On the contrary, it needs to absorb heat from the outside world. This is why the semiconductor car refrigerator can both cool and heat. The compressor car refrigerator is a branch of the traditional household refrigerator. The working principle is also that the motor provides mechanical energy, and the compressor does work on the refrigeration system. The advantages of this type of refrigerator are undoubtedly good refrigeration effect, large capacity, and can be frozen. The disadvantage is that it is large in size and heavy in weight, and it is inconvenient to carry when used in a car.
Of course, if you need a larger refrigerator, then the 12V DC Freezer would be a good choice.

The freezer is another name for refrigerators and freezers. In recent years, with the continuous development of China, more and more China freezers are exported. In addition to my country’s economic strength and comprehensive national strength, the quality of china freezer is getting better and better.
The freezer refrigeration system is composed of 4 basic parts, namely the compressor, condenser, throttling part, and evaporator. 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 a better cooling effect and better corrosion resistance than aluminum pipes or composite pipes. High-quality copper coils have the advantages of high cleanliness in the pipe and fewer pipe joints, which can effectively prevent internal leakage or blockage failures in the refrigeration system. The round tube is processed into a rectangle so that the contact between the evaporation tube and the cold transfer liner is changed from point contact to surface contact, which enlarges the transfer area and speeds up the cooling speed.
Nowadays, the quality of freezers is getting better and better, and environmental protection and energy-saving are also getting better and better. In addition to energy-saving, the freezer also uses solar energy to operate the freezer. This is the solar dc freezer , which maximizes the use of natural energy and realizes the purpose of energy-saving and environmental protection.

The use of traditional refrigerators consumes a large amount of conventional energy, and the indirect pollution to the environment is becoming more and more serious. From the perspective of China’s current energy supply and environmental protection needs, the development of refrigerators that use clean energy will be the general trend. Also, there are many remote areas and nomads in China that have not yet been included in the power supply network, and there is no condition to use refrigerators to store food. These also provide a potential market for the development of Solar DC Freezer .
However, some aspects of the development level of solar energy utilization are theoretically feasible and technically mature. However, some solar energy utilization devices have low efficiency and high cost, and the current laboratory utilization efficiency does not exceed 30%. In general, the economy cannot compete with conventional energy sources. For a considerable period in the future, the further development of solar energy utilization will be mainly restricted by the economy.
However, under the premise of energy-saving development, China freezer will only have more applications for solar energy.

As one of the essential household appliances in the daily life of most families, the function of the refrigerator is self-evident, but because it is a special household appliance that is plugged in throughout the year, the choice of temperature and adjustment of the corresponding mode It is also related to whether the refrigerator can achieve the purpose of energy saving and emission reduction. But mini car freezer does not need to worry about electricity bills, and basically can’t consume much electricity bills.
Mini Car Freezer is suitable for indoor and outdoor use, on the road, or in the office, the mini hot and cold box can keep your food and beverages cool and fresh. The switch after turning the box is converted into a heating system, which can heat the food to 65°C. With cooling and heating functions. Placed in different directions, it is indeed multi-purpose. The mini hot and cold box can conveniently store sandwiches, fruits, cosmetics, and more kinds of items.

In the hot summer, we cannot do without iced products, cold drinks, ice cream and so on. In addition to these, we also have some foods that need to be kept fresh, which inevitably requires a large refrigerator. However, if the refrigerator has a large volume, it will be more inconvenient if we want to carry it, so there is a mini car freezer to carry it at any time.
For example, many long-distance drivers will particularly need to compromise the refrigerator. Whether it is water during the trip or some girls’ cosmetics, lipsticks, facial masks, etc., or chocolates to supplement energy, they need to be placed in the refrigerator. . Mini Car Freezer will be very convenient. It can also be placed indoors. In summer, there is no need to walk from the room to the kitchen to get iced food. This can be achieved indoors. These conveniences are only part of it.
Of course it doesn’t mean that after owning Mini Car Freezer. For a family, the volume of the Mini Car Freezer is too small, and it is impossible to fit the things that a family needs to put in the refrigerator. Therefore, if it is used at home, it is best to equip a refrigerator with a large volume. For example, the volume of the 12V DC Freezer is large enough.

The freezer is also a kind of refrigerator, and it is also common around us, and the 12V DC Freezer is also one of the common freezers. So what are the advantages of the 12V DC Freezer that make more and more people choose it?
The door and the box body are sealed with nano-material door seals with good low-temperature resistance and aging resistance, which effectively avoids heat loss, and can extend the life of the heating element, and effectively guarantee the airtightness of the task room. The exterior of the cabinet is made of high-density polyurethane foam, and the thickness of the insulation layer is reasonably designed so that the heat cannot be transmitted when the equipment is running at low temperature, and the insulation effect is good. Active defrosting function, suitable for low temperature and high humidity areas, the use of anti-condensation techniques for exterior doors, 85% humidity without condensation.
However, the current of the general mini car freezer is almost between 12V-24V. If the Mini Car Freezer is not used very much, it is about 12V.

Solar energy is one of the energy we can use. We sometimes use it for heating or drying things, etc. It is our natural energy source. There are many places where solar energy can be used, so when it comes to refrigerator cooling, solar energy is no exception. Like Solar DC Freezer is the representative of solar cooling.
The use of solar energy for refrigeration is an important part of solar energy utilization. Solar cooling and refrigeration also use solar energy as an energy source to generate steam or hot water to drive ordinary refrigerators. It is a field with great development prospects and a hot spot in current refrigeration technology research.
One is to use solar collectors to realize light-to-heat conversion and heat cooling; the other is to use photoelectric converters to realize photoelectric conversion and electric cooling. The latter is to first convert solar energy into electric energy and then use electricity for cooling, such as photovoltaic and thermoelectric cooling. However, due to its high cost, there are few research applications at present. There are many studies and applications of photothermal refrigeration methods such as absorption, adsorption, and ejection. Among them, absorption and ejection refrigeration have entered the application stage, and adsorption is still in the research stage.
When solar cooling and refrigeration technology is fully popularized, China freezer industry may be at a new stage.
