Five misunderstandings of home appliance purchase

For most of the 80's (rich second generation, rich handsome please ignore this article), struggling hard work, parents scraping together to help them buy a small apartment. When you live, you can't naturally spend as much as you like to fall in love. For home appliances, how to choose, how to match? Enough? Or is it in one step? All users need to consider. When you live your money, you can't overstate this sentence.

Select home appliances, many users like to go to a professional store, listen to sales staff introduction, involving some technical vocabulary, it is inevitable that it is difficult to avoid confusion, and sometimes it also trips to buy errors. Blindly listened to the words of shopping guides and chose some flashy products. This article will start from the five mistakes, to provide users with guidance on the purchase.

LCD TV size or see features?

Intelligent television is a trend in the development of home appliances. With networked, high-definition, and game-playable TVs, TVs use more original features while retaining traditional features. The smart TV based on the latest Android platform provides users with more convenience.

However, when the topic is changed, the 80s are basically electronically controlled, and smart phones and tablet computers are all quite a few years old. Do we still need the intelligent functions provided by television? At present, the joint venture brand smart TV is generally higher in price. In the same price, choose the function or choose the size?

The author's idea is to choose the size, television is used to see, and the larger size will undoubtedly provide a better visual experience. At the same time, the higher quality LCD panel is more excellent in the detail processing of the picture quality. Think about it, television is watching for a long time? Or is it a long time to go online? Of course, the author just gives you a way of thinking when buying, starting from the needs, buy yourself the most needed. Starting with a visual experience and then choosing a product is the key to purchase. Don't let the function take over.

Cold and cold? How to choose a good refrigerator?

When choosing a refrigerator, we often hear the words “straight cold” and “wind cooling”. What is cold? What is direct cooling? Under normal circumstances, "direct-cooled" refrigerators have low power consumption and good preservation effect. The disadvantage is that the refrigeration tubes in the freezer are prone to frost. The characteristics of the air-cooled refrigerators are: the refrigerators are of high quality, but the power consumption is also higher. Because there are fans and defrost heaters in its cooling system. However, food is easy to dry, which is not good for freshness. And the noise is also great. At present, many high-end refrigerators use "mixed cooling".

The refrigerator has no frost, because it has an evaporator inside, and then sends the cold air to the refrigerator through fans and ducts. Since the evaporator is not in direct contact with the food, the evaporator can be used to heat the evaporator for a short time. Warm up, refrigerate immediately after defrosting. Because its evaporator is hidden inside the refrigerator, we can't see the frost it produces. In this process, due to the higher wind speed, the convection of the air in the food and the refrigerator is very strong, and the water evaporation is very fast. Food can easily dry.

Air-cooled chassis internal structure

Compared to air cooling and direct cooling, computer temperature control is more functional in function. Precise control of the temperature can be more effective preservation of real objects. In addition, the greater ease of the refrigerator will undoubtedly provide more convenience to those who only go to a supermarket once a week. But then again, no matter how good the fresh-keeping function does not have the fresh vegetables just bought, if the budget is limited, ordinary refrigerators are sufficient.

What is frequency conversion? Air conditioning can really save power?

Inverter air conditioner is another key word that users often hear when choosing air conditioner. What is inverter air conditioner? Inverter air conditioner is actually using the inverter compressor air conditioner. Which is divided into DC conversion and AC frequency conversion. The AC variable frequency compressor first converts AC power into DC power, and then lowers DC power into AC power of different frequencies, basically without changing the working mechanism of the conventional compressor. DC compressors only convert AC to DC, so the compressor must be changed.

Inverter compressors will adjust the operating frequency according to the temperature status, and will not stop during the working process. At the same time, they do not need to start the capacitor, so the work is more stable, more accurate temperature control, but also more energy-efficient.

The difference between the structure of fixed frequency compressor and variable frequency compressor

Of course, limited by the temperature setting state, the user's use of air conditioning time, etc., the energy efficiency of inverter air conditioner is there, but it is not so obvious. For example, if the user sets an excessively high temperature, inverter air conditioners and fixed-frequency air conditioners will be fully loaded. At this time, the power-saving advantages of inverter air conditioners will not be reflected.

Non-fluorinated refrigeration? What is fluorine-free?

"This air conditioner/refrigerator is fluorine-free and does not damage the ozone layer." God horse is the ozone layer? Freon (Freon), chlorofluorocarbons, a generic term for several fluorochloromethanes and fluorochloroethanes. Freon is a colorless gas or volatile liquid at room temperature, slightly scented, low toxicity, and chemically stable. The most important of these is dichlorodifluoromethane CCl2F2 (F-12). Dichlorodifluoromethane is a colorless gas at normal temperature and pressure. It is widely used in refrigerators and air conditioners as refrigerants.

However, it is not fluorine but chlorine that destroys the ozone layer. The chlorine in Freon is affected by the high temperature of ultraviolet rays, which volatilizes out and becomes chlorine. Chlorine acts as a catalyst between ozone and oxygen, so a chemical reaction of “Cl+O3===O2+ClO ClO+O3===O2+Cl” causes ozone to be quickly consumed. A fluorine-free refrigerator actually refers to a chlorine-free refrigerator. In February 1985, the British Antarctic expedition team captain J.Farman first reported that since 1977, the total amount of ozone over Antarctica has rapidly decreased by about half from the end of September every year, forming an "ozone hole" until November. Gradually restored.

After 2010, China will completely ban the use of Freon. A measure aimed at protecting the ozone layer was recently introduced in China. According to the schedule set by relevant departments: By 2010, China will completely ban the production and use of ozone-depleting substances - Freon. According to this schedule, China will begin to freeze the production and consumption levels of Freon from the average level of 1995-1997 from July 1, 1999, and then decrease year by year. On January 1, 2010, Freon was banned by our country. Now, except for individual cottage brands, all regular products are fluorine-free (chlorine-free).

What is the difference between a big washing machine?

The same model? Why is the price difference so great? I believe many users have such questions. For example, I previously selected Sanyo XQG65-L903BCX and Sanyo XQG55-L832G two washing machines, if only from the appearance point of view, two products are like a class, but for a price gap of 1,000 yuan it.

The first difference in price is the difference in volume, Sanyo XQG65-L903BCX is a 6.5Kg model, the latter is a 5.5Kg model, a larger volume can no doubt be able to wash more clothes for frequent washing For users of clothes, it is undoubtedly more practical.

Volume, washing mode is the main reason causing the difference between washing machines

In addition, the setting of the two products for the program is not nearly the same, Sanyo XQG65-L903BCX more abundant in the washing process of clothes, it is more intelligent "smart." More equipped with a more high-end liquid crystal display, while the air sterilization function is also the latter does not have.

For the user's choice, in fact, I prefer to choose the latter, because the washing effect will not be much worse, the latter is more affordable. It is also the original intention of "the money is spent on flowers." For the average consumer after 80 is also more practical.
