Question 2: How to choose an air conditioner depends on the comparison of parameters. 1. Cooling power and heating power are easy to understand. They determine the power consumption of air conditioners, but the greater the power, the stronger the cooling or heating.
Second, the circulating air volume, the circulating air volume of air conditioners is often a very important parameter, but it is ignored by most sellers. The consciousness of circulating air volume is: the air volume blown out by the air outlet of the air conditioner every hour, so the greater the circulating air volume, the faster the cooling and heating speed of the air conditioner.
3. Heating capacity or refrigeration capacity Refrigeration capacity and heating capacity are the most basic parameters of air conditioning. Among them, the cooling capacity determines the number of air conditioners, which can also be clearly seen in the air conditioner model. For example, an air conditioner decorated with KFR-32GW on the front desk has a cooling capacity of 3200W, but its heating capacity is not necessarily. In fact, buying an air conditioner depends not only on the cooling capacity, but also on the heating capacity under the same cooling capacity. Cold/heat ratio = heating capacity/cooling capacity. When you hesitate to buy two similar air conditioners, compare the cold-heat ratio of the two air conditioners, and you will know which air conditioner has good cooling and heating effect.
Fourth, electric auxiliary heating For air conditioners, heating has always been the bottleneck in the use of air conditioners. In other words, if an air conditioning refrigeration pipe can manage 20 square meters, it may only manage 15 square meters for heating. This is why buyers always feel that the heating effect of air conditioning is not good when using air conditioning. Therefore, electric auxiliary heating was born. As the name implies, electric auxiliary heating is to increase the heating capacity by electric heating in addition to the Freon heating of the air conditioner itself, so as to achieve better heating effect. Therefore, buyers who emphasize the effect of winter use must buy air conditioners with auxiliary heating.
Verb (verb's abbreviation) noise value At present, basically all air conditioners will be marked with noise value, but this data cannot be simply viewed. First of all, we must understand how the noise of air conditioning is produced. The following two aspects will lead to noise: 1 noise caused by friction such as motor operation; 2 Noise caused by air circulation. Among them, the noise generated by air circulation is a very important aspect of noise, that is, the "wind" we usually listen to when using air conditioning. In general, the greater the air volume, the higher the noise; Small air volume and low noise; When the air volume is zero, there is naturally no noise. Therefore, to treat the noise value correctly, we should combine the noise with the circulating air volume. At present, many manufacturers flaunt their low noise, which actually reduces the circulating air volume, thus affecting the use effect of air conditioners. The real silent air conditioner is not that the noise is as low as possible, but that the noise is as low as possible without reducing the circulating air volume, which is also the purchase method of silent air conditioner.
Sixth, the weight of the outdoor unit Most consumers ignore this parameter. In fact, this is one of the important parameters of air conditioning. It directly reflects the quality of air conditioning materials. Due to the overall increase in copper prices in recent years, many air-conditioning enterprises began to reduce the wall thickness of copper tubes to reduce costs, and even many small and medium-sized brands began to use aluminum tube air conditioners. At the same time, the service life and effect of air conditioners are greatly reduced. The direct surface consequence of saving raw materials is naturally that the outdoor unit becomes lighter, so consumers have to care about this important parameter.
Question 3: What do you think of the number of air conditioners? Look at the two numbers in front of the air conditioner model first. For example, the number is 25, which means that the cooling capacity of air conditioner is 2500W, which is air conditioner;
The second is to look at the signs on the air conditioner. The cooling capacity of 2500W is Pima air conditioner, which is suitable for rooms around 12 square meters. Less than is a small air conditioner, greater than is a large air conditioner; The air conditioner with a cooling capacity of 3200W is 1.25, which is suitable for a room of about 16 square meters. There is an air conditioner with 1.5, with a cooling capacity of 3500W, which is suitable for rooms with a capacity of 18 square meters, and there are two air conditioners with a capacity of 5000W, which are suitable for rooms with a capacity of 25 square meters.
The third is to look at the refrigeration capacity marked in the manual.
The first parameter depends on the cooling capacity, and the second parameter depends on the input power and energy efficiency ratio level; The third is to look at the noise level and size modeling; The fourth is to look at the type of air conditioner, whether it is ordinary constant speed or frequency conversion; The fifth is to look at the variety and model of refrigerant.
Question 4: How to compare the parameters when choosing an air conditioner? Choosing an air conditioner mainly depends on several parameters.
Whether the cooling capacity is sufficient is generally determined according to the room area.
Then there is the energy efficiency coefficient, and the bigger the better.
Question 5: What parameters should I look at when buying an air conditioner? 1. Because the heating effect of air conditioner is lower than the cooling effect (the applicable area in winter is smaller than that in summer), the heating index should prevail when buying air conditioner. Therefore, the purchase of air conditioners is based on the applicable area in winter. Of course, if you buy a single-cooled air conditioner, it depends on the applicable area (summer).
2. Due to the differences of room conditions and regional climate, and the plan for extreme weather, we should buy large air conditioners instead of small ones. Therefore, air conditioning should be selected according to the applicable area in winter and the lower limit of applicable area in winter.
3. Select energy efficiency grade: The current national energy efficiency standard GB 1202 1.3 stipulates five energy efficiency grades, and the higher the grade, the more energy-saving it is (from low to high, from five to one).
4. The basic function of air conditioner is cooling and heating, and there are many kinds of additional functions of air conditioner in the market. Consumers should consider cost-effective factors according to their own needs.
Or try the beautiful air conditioner KFR-23GW/DY-A8 (E2) class 2 air conditioner. Cold fast, warm fast, cost-effective.
Question 6: How to illustrate air conditioning parameters with examples?
For example, KFC-26GW/BP2DN1Y-W.
K is air conditioning
F is split.
R is the cold and warm type, and the single cooling type does not have this sign.
26, the refrigeration capacity is 2600 watts.
G stands for hang up.
W, for external machines
BP is frequency conversion.
2 is secondary energy efficiency.
D stands for electric auxiliary heating function.
N 1 is R4 10A environmental protection refrigerant.
Y is remote control.
W is the model identification number. This machine is a W model in frequency conversion series.
Power consumption calculation:
The cooling capacity is 2600 watts, that is, 1p, and the power consumption is 735 watts, that is, 0.735 kw.
Power consumption = 0.735kw×1h = 0.735kw.
That is, 1 hour consumes 0.735 degrees of electricity.
Question 7: What do you mainly look at when buying air conditioners? Look at the price:
This year, the prices of copper and aluminum, the main raw materials of air conditioners, have been rising all the way. Compared with the same period last year, the copper price increased by more than 65,438+000%, and the aluminum price increased by more than 60%. However, many enterprises have greatly reduced the price of air conditioners and promoted sales. Obviously, it's the same as buying them for homework last year.
Most of these promotional items are old products, and old air conditioners often cause damage to some parts during storage, and it has been several years before they enter the family. According to the relevant national regulations, the recommended safe service life of air conditioners is 10 year, so it can be concluded that the old products have virtually deprived us of our actual service life. Therefore, buying air conditioners to see that the price is too outrageous is mostly tricky. Only new products with small price fluctuations can guarantee product quality and see energy efficiency:
Many friends are worried about the electricity bill at home. They are comfortable after driving for a long time, but the electricity bill is increasing every month. At this time, some friends will ask, is there any way for us to simply estimate how much it costs to use an air conditioner once?
This requires us to look at the energy efficiency rating when buying air conditioners. As we all know, the new air conditioning standard divides air conditioners into three grades according to the energy efficiency ratio, in which 1 means the highest energy efficiency; Level 2 represents the energy-saving evaluation value, that is, the minimum requirement for evaluating whether the air conditioner is energy-saving; The third level indicates the limited value of energy efficiency, that is, the product reaches the market access threshold after the implementation of the standard. The original 3-level energy-efficient air conditioner will be eliminated, the original 2-level energy efficiency will be reduced to a new 3-level, which will become the industry entry threshold, and the original 1 will be reduced to a new 2-level, which will become the new energy-saving product threshold. At present, the old standard 3, 4 and 5 energy-efficient air conditioners on the market will all be delisted. Therefore, it is best not to buy air conditioners with fixed frequency below level 2. Stopping production means that related accessories will also stop production, so even the best after-sales service is an armchair strategist.
Look at the refrigerant:
On the one hand, at present, at least 80% of domestic air conditioners in China use HCFC refrigerant R22, which is very harmful to the ozone layer, seriously endangering human living environment and the overall ecological environment. With the rise of low-carbon trend and the further strengthening of people's awareness of environmental protection, the fluorine-free inverter air conditioner, which is superior in energy saving and environmental protection, will surely win more people's hearts. According to Montreal Protocol, R22 refrigerant will be eliminated in 2020, so it can be said that fluorine-free frequency conversion is the inevitable trend of air conditioning development in the future.
On the other hand, the fluorine-free inverter air conditioner solves the problems of slow heating and low efficiency in winter, and truly realizes low-carbon emission. Take Haier, which has the best fluorine-free frequency conversion in the industry, as an example. The electricity saved by each air conditioner is equivalent to 850kg CO2 reduction every year. According to the use of 12 years, the CO2 emission reduced in 60 years is more than that absorbed by 10 towering trees! If you love your home, you love the earth. I don't need to tell you how to choose ~ ~
Question 8: Buying air conditioners mainly depends on what household air conditioners should be bought. 1. Avoid buying air conditioners during peak hours. When buying air conditioners during peak hours, businesses are usually in a busy working state. Whether it is delivery or installation, it often takes a long time, and after-sales service can't keep up. So, if you want to buy an air conditioner, you'd better plan ahead.
2. Check the indicator. Air conditioners usually have the following three indicators: cooling capacity (the cooling capacity is an important basis for purchasing air conditioners, and the cooling capacity of air conditioners is too small to achieve a good cooling effect), energy efficiency ratio (the size of energy efficiency ratio can reflect the energy saving situation of air conditioners, and the greater the value of energy efficiency ratio, it means that air conditioners will consume less electricity and consume less electricity), and noise (the noise generated during air conditioning operation is too large, which will not only affect users themselves).
3. Certification mark. At present, there are two reliable certification marks for air conditioners. One is the "3C mark", which is certified by the state and can be issued by the supervision and administration commission, and the other is the "energy efficiency mark", which is mainly divided into five grades. The higher the grade, the higher the energy efficiency ratio and energy saving.
Matters needing attention in purchasing air conditioners
1, floor position. When consumers buy air conditioners, they need to pay attention to the floor where their families are located. If you are on the top floor, you should choose a crowded air conditioner on the basis of the original area when buying air conditioners.
2. Room layout. If it is necessary to install air conditioner in a room with direct sunlight and there are many corners in the room, you should also choose a larger air conditioner when choosing holes.
3. Applicable area: Different air-conditioning products have different applicable room areas, such as12m2 = 1,16m2 = 1, 20-23m2 =1.5,40-50m2.
4. In general, it is better to choose a large air conditioner than a small one, because the factors that affect the air conditioning work are not only the size of the room, but also the closed degree of the room and the number of electrical appliances.

Question 9: Buy air conditioners to see which models have parameters greater than 1+25. Cooling and heating should be good. Pay attention to energy efficiency before the election, not to save electricity, how many decibels the noise is, how about repair rate, and how about after-sales. These are all similar.
Question 10: What should I do to buy an air conditioner? Mainly depends on the brand, word of mouth, parameters, parts, technology, as well as after-sales service and so on.
Mainstream brands: Panasonic, Daikin, mitsubishi electric, Gree, Midea, Haier, Oaks, etc. For the representatives of imported brands and domestic brands, panasonic air conditioning has the largest market share in Japan, with a history of 60 years. Has its own compressor production base and independent research and development base of frequency conversion technology. Gree air conditioning is a leading enterprise in China with mature technology and good strength.
In terms of word of mouth, you can go to JD.COM Mall and Tmall Mall to see user comments. High evaluation, good reputation. In JD.COM and Tmall, Panasonic and Gree have their own flagship stores.
In terms of parameters, we can see the cooling capacity, power, air volume and energy efficiency. For example, a Panasonic imported air conditioner, VE9K 1, has an energy efficiency ratio of 5.84, which is rare in the market. Parameters such as cooling (heating) capacity, cooling (heating) power and energy efficiency ratio can be viewed on the energy efficiency label.
Technically, the heating and cooling technology is self-evident, fast and stable, and the air supply range is wide. At present, the technology of air purification is still popular, except for PM2.5\ sterilization \ deodorization, such as Panasonic patent-grade Nanoe &；; Nanoe-G double ion purification technology, Gree's IFD dust collection technology, and some filters except PM2.5, antibacterial filters, internal self-cleaning and so on.
Generally speaking, the quality of big brands is guaranteed; The higher the energy efficiency rating, the more expensive it is, but the more electricity is saved. If the air quality in the home environment is not good, you can consider the model with air purification function. On the after-sales side, big brands like Panasonic and Gree have good services. Pay attention to the vacuum degree of inverter air conditioner.
