In today's life, supermarket refrigerators are very important electrical equipment, but many friends do not know what requirements to make when making purchases. So, let's introduce the requirements for supermarket refrigerator selection to you.

1. Fluorine free supermarket refrigerators are the best

The corrosive effect of Freon on the earth's ozone layer has been confirmed by scientific research, but it is the best foaming agent and refrigerant for supermarket refrigerators known so far. The refrigerator of the electric supermarket with Freon (CFC-11) as the foaming agent has uniform foaming, is not easy to deform, has no corrosion to the plastic plate of the inner tank, has no dramatic change in aging and thermal insulation, and maintains power saving.

Its thermal insulation performance can effectively isolate the convection between the cold air inside the box and the hot air outside the box: Freon (CFC-12) is used as the refrigerant, which has large refrigerating capacity, non-toxic, non combustible, good chemical and thermal stability, and good adaptability to the metal, organic materials and lubricating oil it contacts. Compared with Freon, all substitutes in the world have some shortcomings.

2. The greater the freezing force, the better

The refrigeration force is an important technical indicator of refrigeration appliances, but the purpose of refrigeration appliances varies and the performance requirements are also different. Compared with commercial, medical, scientific research and other special important technologies, the most important technology for household electric supermarket refrigerators is

Performance is not refrigeration but preservation. Excessive freezing force not only unnecessarily increases user expenses, but also damages the internal organization of food and affects nutrition. Especially for Chinese families who pay attention to color, smell and taste, preventing Food spoilage is just

The most basic requirement is preservation, which is the first need for consumers when purchasing supermarket refrigerators.

3. Supermarket refrigerators are better at saving electricity

Like refrigeration power, the power consumption of refrigerators in electric supermarkets is also a significant performance indicator. However, in order to achieve the best preservation effect and energy efficiency ratio, it is not enough to focus solely on reducing electricity consumption, and optimization is necessary

The structure and refrigeration design of.

Enterprises can achieve the goal of saving electricity by simply thickening the insulation layer (with corresponding increase in cost), or by adopting new technological achievements to improve energy efficiency. Therefore, it cannot be one-sided emphasized that "the more electricity is saved, the better"

4. The more functions of supermarket refrigerators, the more advanced they become

Some companies prioritize complexity in terms of functionality, and regardless of which consumers they target or whether they need it, they always design their products with increasingly complex features. The result is not only that users spend a lot of money on a bunch of impractical functions, but more importantly, due to cumbersome design, faults occur frequently.

In addition, from a technical perspective, there are significant differences in the required technologies due to different stem functions; To have a considerable freezing power, the power must be matched, and there is a certain limit to energy-saving and mute; To be fluorine free, substitutes must be used, and substitutes

Some are prone to leakage, while others corrode the inner lining, which increases the probability of failure. The lifespan of supermarket refrigerators is also affected, and it is impossible for a product to have the best performance in all aspects. All kinds of essential oils may not work well.
