Is the refrigerator prototype designed for use in shopping malls when it leaves the factory 20

The prototype is the same as the normal machine, the principle:

1) Compression refrigerator: This kind of refrigerator provides mechanical energy by the electric motor, and works on the refrigeration system through the compressor. The refrigeration system is made by using the principle of low boiling point refrigerant to absorb heat during evaporation.

Its advantage is that it has a long life and is easy to use, 91 to 95% of the world's refrigerators fall into this category. Commonly used refrigerators use a refrigerant called R600 refrigerator A as a heat "porter" to "transport" the "heat" in the refrigerator to the outside of the refrigerator.

2) Absorption refrigerator: This kind of refrigerator can use heat sources (such as gas, kerosene, electricity, etc.) as power. The ammonia and hydrogen mixed solution are used to achieve the purpose of refrigeration in the process of continuous absorption and diffusion. Its disadvantage is low efficiency and slow cooling, and it has been gradually phased out.

3) Semiconductor refrigerator: It is a refrigerator that uses the principle of direct current to produce the Peltier effect on the junction of the PN-type semiconductor.

4) Chemical refrigerator: It is a refrigerator that uses certain chemicals to absorb heat strongly when dissolved in water to obtain the refrigeration effect.

5) Electromagnetic vibrating refrigerator: It is a refrigerator that uses an electromagnetic vibrating machine as the main power to drive the compressor. Its principle and structure are basically the same as those of compression refrigerators.

6) Solar refrigerator: It is a refrigerator that uses solar energy as a cooling energy source.

7) Adiabatic demagnetization refrigeration refrigerator.

8) Radiant refrigeration refrigerators.

9) Solid refrigeration refrigerators.

The prototype is the same as the normal machine, but it is found from the new machine and placed as a sample in the shopping mall for customers to understand. Because the prototype has been unpacked, it can't be regarded as a new machine (and some because of frequent wiping, there will be scratches on the surface of the machine or something), if the user buys, it will generally be cheaper than the new machine, but its function should be the same as the normal machine. So, sometimes, in order to save some money, customers will choose a prototype with no functional difference.

Prototypes sometimes sell faster than normal machines! Everyone wants to save money these days!

To deceive consumers, the general prototype is the same as the others! And buy a prototype ** is to be discounted!

Nonsense, don't believe them, the prototype is the same as any other machine.

Refrigerator mockups in shopping malls can be bought:

1. The prototype products in the shopping mall are all first-class, and some samples are never energized, and they are displayed for a long time, and there will hardly be any problems except for the appearance; Even if it is powered on, it will not store food and other items, but it is necessary to take into account the wear and tear of long-term waiting.

2. The prototype is cheap, usually about 6% off the retail price, which is the prototype given by the manufacturer to the shopping mall, but if the discount is more than ** sold, it is not cost-effective, and it needs to be considered.

3. The prototype also enjoys the first warranty. When buying a prototype, you should check whether the accessories for this product are complete. When issuing invoices, you must ask the sales staff about after-sales service, how to warrant, how long the warranty is, etc., which will be different from different regions and stores.

Problems to be paid attention to when buying a prototype:

1. Due to the display time of the prototype, the fuselage may have some wear and tear, check whether the fuselage has major defects.

2. The prototype is placed for too long, it is easy to affect the performance and quality of the product, and it is likely to pass the three-pack period of after-sales service.

Refrigerator prototypes in shopping malls can be purchased. One of the big advantages of the prototype is that the prototype can be discounted by 6-7, and the prototype has the following advantages:

What you see is what you get: the prototype is displayed to customers in the shopping mall, and customers can directly see the prototype in kind, and the prototype is the physical object that arrives at home after purchase.

Appearance and design: The prototypes of the shopping mall are all high-quality products, the appearance design and quality are very good, and the design style also represents the most popular fashion at the moment.

Internal structure: The internal structure of the prototype is scientific and reasonable, and the space layout is large, which is convenient for the size and layout of the new refrigerator purchased in the future.

Traces of use: The prototype is used by customers, and customers may have various experiences with the refrigerator during the experience, leaving traces of use.

**Discount: The prototype is usually displayed as a new product, and when the new product is sold for a period of time, there will be a certain **discount, so that the cost performance of the prototype is still very high.

When buying a prototype, you need to pay attention to the following aspects:

Confirm whether the prototype is **: When buying the prototype, you need to confirm whether the prototype is ** to avoid buying counterfeit and shoddy products.

Confirm whether the prototype has been repaired: When purchasing the prototype, you need to confirm whether the prototype has been repaired to avoid purchasing products with maintenance records.

Confirm the warranty period of the prototype: When purchasing the prototype, you need to confirm the warranty period of the prototype to avoid purchasing expired or unwarranted products.

Confirm whether the accessories of the prototype are complete: When purchasing the prototype, you need to confirm whether the accessories of the prototype are complete to avoid purchasing products with missing accessories.

Confirm the invoice of the prototype: When purchasing the prototype, you need to confirm whether the invoice of the prototype is complete to avoid purchasing products without invoices.

In short, the refrigerator prototype in the mall can be purchased, but there are some details that need to be paid attention to. Before purchasing, you need to carefully check the appearance, performance and accessories of the prototype to ensure that the prototype you purchase meets your needs and standards.

Yes, the refrigerator prototypes in the mall are also **, and they are cheaper.

1. It's better not to buy a sample of the machine, Qiandu

Tens of thousands of people have touched the appearance of zhi and old, to put it bluntly, dao is second-hand goods, and the value of the second goods is so much money

2. The general shopping mall is like this kind of large household appliance prototype** is generally a new model back, need to vacate this position for the new model, the old model manufacturer is not in production, this model is not on sale or the quality is problematic will be at a low price**.

The prototype refrigerator that has been placed in the store for a long time may only look old, but it does not belong to the second-hand phone, let alone a faulty machine. Because it's just used as a sample, it's not really used. When the store replaces the sample of the new model, it will generally be discounted after being removed, and it is still responsible for the three packs, if it is at the market price.

Seven or eight percent off the sale, it is still worth buying.

Yes. It is recommended that you buy! Clause.

1. The prototype of the refrigerator is actually a new machine, which is not connected to the power and operates, and it may be more ash, and it is estimated that it has also been wiped clean; Clause.

Second, the preferential policy within Haier Dermabrasion Group for employees to purchase prototypes is usually 6-8% off, and some models can be bent to 5% off during holidays such as the Spring Festival; Clause.

Third, the after-sales service does not distinguish between the prototype or the new machine, as long as it is Haier's products, enjoy the service, if there is an invoice, the warranty time is calculated from the date of issuance of the invoice, if there is no invoice, the warranty time is calculated from the date of production of the machine (the production date can be found by looking at the flow code of the machine itself). The refrigerator you are talking about, the original price is 1030, the prototype price is 799, which is equivalent to a discount, it is still more cost-effective, and the internal purchase is about the same price, in addition, the mall can have points, and there are some freebies!

The refrigerator prototype of the mall collar can be bought, because these prototypes are **, that is, they have been placed for a long time, and they may be dirty on it, or the real world is old, and the use should be no problem with lifting the middle limb and selling it.

Although it is used as a prototype, it does not affect its use. And the ** of the prototype will be relatively lower. As long as he can guarantee that the demolition will be guaranteed within the time set by the Zhaoyu Tong clan, he can buy it.
