What kind of refrigerator is suitable for the home, do you know how to buy?

In the decoration, are to consider the purchase of appliances, need to match is the style of the home, as well as the size of the purchase, these are to be considered in advance, for the purchase of refrigerators you know how much you need to pay attention to what?

A, buy a refrigerator to know the dry parameters

1, refrigerator volume

① single person recommended 50-100 liters of single-door refrigerator, it is smaller, the capacity of a person to use enough.

② recommended for a family of three to use 200 liters of double or triple door refrigerator

③ recommended for a family of three to use 300-600 liters of the door to the refrigerator

2, energy efficiency level

refrigerator is a family of home appliances 24 hours a day full-time operation, so the power saving aspects to be taken into account, the energy-efficiency standards are divided into five levels. 1-level products are the most energy efficient, but the price is higher. The most energy-efficient products, but the price is also more expensive, the average family with 3 levels of energy-efficient refrigerator is already enough, more affordable.

3, freezing star rating (freezing capacity)

It refers to the ability of the refrigerator to freeze food within 24 hours, as well as the time the food stays fresh.

One star rating (? -6°C, keep fresh for 1 week)

Two-star (? -12°C, keep fresh for 1 month)

Three-star (? -18℃, freshness 3 months)

Four-star (<-18℃, freshness 3-6 months)

4, running noise

Fixed-frequency refrigerator exists compressor start-up spring noise, inverter refrigerator exists compressor high-frequency operation of the cicadas, the refrigerator's noise is mainly from the compressor's operation, the mute refrigerator can be controlled noise in the 35-45 decibels interval

5, refrigerator volume and size

Small double-door refrigerator (volume in 100L, size general width 480mm, depth 550mm, height 1200mm or so)

Large-capacity double-door (volume in 200L, size general width 500mm, depth 600mm, height 1400mm or so)

three Open door refrigerator (volume in 200L, size of the general width of 600mm, depth of 550mm, height of about 1800mm)

open door refrigerator (volume in 600L, size of the general width of 950mm, depth of 700mm, height of about 1800mm)

6, the working principle of the refrigerator

Modern household refrigerators are basically The use of low boiling point refrigerant, vaporized by the liquid state when the absorption of heat makes the temperature inside the box is lowered. Then conduct the heat inside the box to the outside of the box. (can be understood as the heat carried outside the refrigerator)

Two, refrigerator types

1, direct cooling

Direct-cooling refrigerator will be in the box inside the frost, its evaporator is set in the refrigerator, the use of natural convection of air inside the refrigerator to cool the food. It is well moisturized, retains the moisture of the food, and is relatively inexpensive.

2, air-cooled

Air-cooled refrigerator is the air inside the refrigerator first after cooling, and then sent to the inside of the box, back and forth cycle, so as to achieve the cooling effect. The refrigerator cools faster, the temperature balance is good, and there is no frost inside the refrigerator. But the drawback is that it will take away the moisture of the food and blow dry the food.

3, fixed-frequency

Fixed-frequency and frequency conversion refers to the way the compressor works, fixed-frequency refrigerator is when the temperature inside the refrigerator reaches a preset temperature, it will stop running, wait until the temperature inside the box rises, it will run again. So the temperature inside the refrigerator is less balanced, and the food is subject to greater temperature fluctuations.

4, frequency

Inverter refrigerator compressor is constantly adjusting the frequency of the change in the way of working, when the thermostat shows the need to cool down when it will increase the speed of operation, when the refrigerator temperature reaches a predetermined value it will be low-frequency operation to keep the temperature inside the refrigerator constant.

5, single cycle

Single cycle refrigerator, if you buy an air-cooled refrigerator, due to the air-cooled refrigerator is the principle of forced circulation of air, low-end single-cycle refrigerator will travel the phenomenon of string of flavors.

6, multi-circulation

①Multi-airway multi-circulation: inside the refrigerator there are a number of air ducts, through the solenoid valve and fan to achieve the conversion between the circuits, where the need for cold air to where to send.

② dual-system multi-cycle: refrigerator has two separate heat exchange systems, freezer and freezer run separately, do not crosstalk each other. But it's still one compressor.

③ Dual system cooling multi-cycle: the refrigerator has two compressors for refrigeration, the main compressor is responsible for the freezer, the vice compressor is responsible for the freezer. Separate, high production cost and expensive.

Three, what are the brands of refrigerators, which need to pay attention to.

①Haier: Haier itself is a refrigerator company started, the current market share is the first. UniShield and Casadei refrigerators are high-end sub-brands of Haier. Its selling price is affordable, stable performance, cost-effective, in line with mass consumption.

② Siemens: Siemens compressor is basically foreign imports, good refrigeration performance, stability. The price is high, its high-end products have excellent performance, consider the door can buy Siemens.

3 Hisense: Hisense refrigerator corresponds to the low-end market, the price is relatively cheap, in line with mass consumption.

4 Midea: the highlight of the United States refrigerator is its after-sales, in addition to the price of pro-people, complete performance. The lack of budget can buy the United States of America's products, its after-sales service is very powerful.

⑤Panasonic: Panasonic is a Japanese brand with its own core research and development department. Its compressor for independent self-production, environmental protection and energy saving, with core technology as support. The price is relatively high, the performance is complete, with decades will not be bad. Mainly high-end models.
