Teach you how to choose the right refrigerator

A refrigeration mode

Refrigerator refrigeration mode is generally divided into three kinds:

1, direct cooling: you can see the freezer drawer by rows and rows of refrigeration piping, that is, the evaporator surrounded by the freezer or freezer room has an evaporator, freezer room and then an evaporator at the top of the upper part of the evaporator, the evaporator by the evaporator to directly draw heat And cooling. Direct cooling is the earliest refrigeration technology, its advantages are simple structure, low cost, small power consumption, fast freezing speed, low noise, good preservation of freshness and moisturizing effect. The disadvantage is that the freezer is slow to cool down, the temperature inside the refrigerator is not uniform, the need for regular defrosting of the refrigerator freezer, suitable for the drier north and inland areas.

2, air-cooled: also known as cold or frost-free refrigerator. Refrigeration piping hidden, there is a small fan inside the refrigerator will blow cold air into the freezer and refrigerator, forced air flow inside the box, so the temperature inside the box is uniform, fast cooling speed, high refrigeration efficiency (similar to the hot water blowing cooling fast reasoning), easy to use. But the manufacturing structure is relatively complex, high cost, and because it has a defrosting system leading to high power consumption, while the fan inside the box will make the refrigerator noise on the high side, the food is easy to dry and dehydration, suitable for the coast, the Yangtze River, and other humid areas, high power consumption, the effective volume is small. Higher-grade refrigerators take more air-cooled technology, such as the door to the 400-liter or more large refrigerators are commonly used.

3, wind, direct cooling hybrid: using the advantages of the above two refrigeration methods, freezer with air-cooled design, freezer with direct cooling. This eliminates the freezer will not be frosted, eliminating the trouble of defrosting, but also makes the freezer food moisture to be retained to the maximum extent, fruits and vegetables are not easy to become dry. This refrigeration method of refrigerator loudness is more scientific, complex technical process, the price is relatively high.

Second, the type of door (capacity)

The refrigerator can be divided into single-door refrigerator, double-door refrigerator, three-door refrigerator, door-to-door refrigerator and multi-door refrigerator according to the number of doors. People should choose according to their own financial ability and the needs of the people, do not blindly choose a super large refrigerator.

Single-door refrigerator:

The refrigerator has only one door, and generally only has the function of refrigeration without freezing, so it can't make ice, can't put ice cream for a long time. Some single-door refrigerator built in an independent freezer, the capacity is generally between 45-100 liters, the price is about 400-800 yuan. Suitable for single people or people with small capacity needs.

Double-door refrigerator:

Double-door refrigerator is the largest market share of refrigerators, the traditional upper and lower two door design, freezer and freezer separate. Capacity is generally around 85-280 liters, the price gap is relatively large, 800 yuan to tens of thousands of dollars price of refrigerators are available. Suitable for a wide range of people, suitable for single people, two, three, four families, larger capacity . Double-door refrigerator is even suitable for large families or families doing catering small business.

Three-door refrigerator:

Three-door refrigerator is currently more popular refrigerator category, the main thing is that there is a special storage of meat in the middle of the -7 ℃ soft freezer, the temperature can be between 3 to -7 ℃, the meat can ensure that the fresh nutrients are not lost, but also easy to cut, eliminating the trouble of thawing. Capacity is generally around 190-350 liters, the price is also relatively slightly more expensive than the double-door refrigerator. Suitable for the crowd a while wider, the general large family small family can choose.

Door-to-Door Refrigerator:

Refrigerator space volume are very large, generally more luxurious, of course, power consumption will be slightly larger than the double-door, three-door, door-to-door refrigerator features, equipment are more complete. Capacity is generally about 300-600 liters, the price is also relatively expensive, about 3,000 ~ tens of thousands of dollars variable. Suitable for the crowd; large families and catering small business home.

Multi-door refrigerator:

Multi-door refrigerator luxury nothing to say, such refrigerators are more versatile, mainly four-open, five-open, six-open refrigerator. The capacity is much larger compared to ordinary refrigerators. The price is also mostly above 5,000 ~ million dollars.

Third, the compressor type

1, fixed-frequency:

The compressor of the traditional refrigerator is generally fixed-frequency, that is, the power of the refrigerator is unchanged during operation.

2, inverter:

Refrigerator as a result of the whole day in the working state, the use of inverter refrigeration, the compressor is able to start in the refrigerator full-speed refrigeration, to quickly reach the set temperature, and then always in a low-speed operation, energy saving effect is more obvious. Inverter compressor can not only fast refrigeration, but also reduce energy consumption, but also reduces the noise, can be said to be a multi-purpose. The price of products with inverter technology is relatively high, you can choose to buy according to their own needs.

Fourth, look at the energy efficiency

Refrigerator energy-efficiency rating is based on a refrigerator 24 hours to determine the power consumption, so you can through the energy-saving logo at a glance to see how much power consumption of the refrigerator. However, because of this direct perception, consumers ignore the freezing capacity of the refrigerator.

For example, a refrigerator with a 24-hour power consumption of 0.3KW?h has a freezing capacity of 5 kilograms. And a 24-hour power consumption of 0.6KW?h, its freezing capacity of 20 kilograms. Based on the analysis of the actual situation, it is obvious that the latter type of refrigerator is relatively energy-saving, so we cannot unilaterally emphasize ? The more energy-saving the better? Refrigerator energy saving is a relative concept with the refrigerator freezing capacity, in the purchase of refrigerators must remember this.

Fifth, the performance of the machine itself

Input power may be very few people will pay attention to, the input power is too small will lead to the refrigerator compressor for a long time without stopping, which is known as ? The small horse-drawn car? For large-capacity refrigerators, the higher the input power, the better. For example, a refrigerator 216L compressor power is only 80W, while it is smaller than the power of 168L has 100W, which is like a 20 square house installed in a 1.5p air conditioning, and in another 10 square room inside the 1.5p air conditioning effect comparison.

Refrigerator insulation, this is even more difficult to understand. Insulation layer has a thick and thin, but mainly depends on the foam layer materials, technology, foam materials have cyclopentane (C5H10), and vacuum materials. Because the old fluorine blowing agent has an impact on the environment, the Montreal Agreement stipulates that HCFC-141b will be phased out in 2003 in developed countries, while developing countries can be delayed until 2040. Pentane series has excellent environmental performance, inexpensive, easy to obtain, cyclopentane in Europe and the United States has been popularized, but also the future trend of refrigerator blowing agent.

Refrigerator this appliance is a home appliance, buy is used to live, not to see, so before you buy need to understand their own needs for the refrigerator in the end where, is simple to store a small amount of food every day, or usually do not have too much time to buy food, all of a sudden want to store a week of food in it, the demand for a different purchase is bound to be different.

Remember the above points, you will not be blind in the purchase of refrigerators, not spend money can also choose the right product for themselves.
