How to choose an air conditioner? How to choose an air conditioner?

Air conditioner is an extremely common and indispensable electrical appliance in our daily life, and many friends will go to the electrical appliance store to buy an air conditioner and put it at home ready to use. However, when some friends buy back the air conditioner, they find that they don't know how to choose the air conditioner, and the air conditioner that is not selected correctly is easy to deteriorate, damage or cause wear and tear inside, resulting in the air conditioner being unusable at all. So how should we solve this situation that we don't know how to choose an air conditioner?

So let me introduce the steps of how to choose an air conditioner.

Step 1:

When buying an air conditioner, you should know how big your room is and how much space it is used for, so that you can choose the size of the air conditioner.

Step 2:

If it is used in the bedroom, choose the hanging type, which can save space, and if the living room is large, you can choose the cabinet air conditioner.

Step 3:

Choosing a brand, what brand to choose can make the final decision according to your preferences and economic level, it is best to choose a well-known big brand, which is safer and more reliable.

Step 4:

Looking at the energy efficiency ratio of the air conditioner, it will generally be attached to the surface of the machine, the higher the energy efficiency, the better, and the more energy-saving, of course, the higher.

After reading my method, now have you learned how to choose an air conditioner? If you learn it, you can quickly share this method, so that more people know how to choose an air conditioner. While carrying out the above steps, we need to pay attention to the fact that we must choose the air conditioner in combination with the actual situation.

The above are the steps on how to choose an air conditioner.

The basics of choosing an air conditioner:

1. First of all, we must determine the refrigeration capacity of the machine according to the room area, that is, the output power, the usual standard is 200 watts of square meters.

2. Secondly, choose the energy efficiency ratio of the machine, the inverter level 1-5, the new standard of the fixed speed machine 1-3 level, level 1 is the most energy-saving but the most expensive, the fixed speed machine buys the 2nd level, and the inverter machine buys the 3rd level, which is more appropriate.

3. Brand, the representative brands of imported joint ventures are Panasonic and Mitsubishi Electric, and the domestic products are mainly Gree, Haier, Midea, Oaks, etc., and the products are different in terms of price and price.

4. Inverter and fixed speed machine, inverter compressor has good mute effect and precise temperature control, especially suitable for bedrooms, but it is high, and it is necessary to decide according to the budget, and other rooms are not necessary.

5. Now the air conditioners on the market are heat pump type, the heating efficiency of the ambient temperature below 10 degrees is seriously reduced, which is not suitable for use in the northern region of our country.

Brand, quality. Connecting pipes, after-sales, noise, refrigeration and heating speed, **, cost-effective, out of Daikin and Mitsubishi Heavy Industries, Gree, Oaks, Zhigao are good, and the beauty is not good.

Step 1: Determine the model of the host First of all, consider the area and orientation of the house to see if there are large areas of glass windows, so as to calculate the maximum simultaneous use coefficient of the air conditioner. Generally speaking, in an ordinary home environment, the cooling capacity required for actual use is often not the synthesis of the cooling capacity of all rooms, but is lower than the latter, and the former only needs to reach 60% or 70% of the latter.

This saves investment and avoids unnecessary waste. The actual cooling capacity required by the room can be calculated by the following formula: Actual cooling area = building area Housing efficiency 65% (excluding non-cooling areas such as kitchens and toilets) Actual cooling capacity = actual cooling area Cooling capacity per unit area Step 2:

Determine the indoor unit and tuyere according to the actual required cooling capacity to determine the model, each room or hall only needs one indoor unit or tuyere, if the living room area is larger, or rectangular, you can add an extra indoor unit or tuyere. Based on the need for about one horse per 12 square meters. Step 3:

Determine the layout of the air conditioner: 1. The location of the host should pay attention to good ventilation and heat dissipation, which is convenient for maintenance and maintenance, and the location should be as hidden as possible to avoid affecting the appearance of the house and the noise affecting the interior; 2. The position of the indoor unit should be matched with the interior decoration layout, which is generally hidden in the ceiling or hidden at the top of the high cabinet. Generally, indoor units are ultra-thin and only need about 25 cm in height to be placed.

During installation, it is necessary to pay attention to good return air, so that the indoor air forms a circulation to ensure the air conditioning effect and air quality.

According to the size of the room, the number of sunshine positions to choose the number of horses, according to the advance to choose the purchase of the brand, function and model, it is recommended to buy Gree, Daikin, Mitsubishi Electric and other professional air conditioning brands. The models and parameters on Kuba shopping are very detailed, and at 8 o'clock in the evening on the 27th, there is a full-category night total benefit activity that is basically selling at a loss.

The quality and service of the famous brand are relatively good.

1, energy efficiency ratio, mainly look at the signs of the levels, 1 is the best, 5 is the worst, but there is no need to force it, because in fact, the best and the worst are very small in terms of power consumption, if you put it in a year, it is not a few degrees, I think it is almost negligible, as long as you choose more than 3.

2, according to the reasonable purchase of indoor space, generally small room choose 1 horse, living room medium choose one and a half horses, larger living room choose 2 horses, cabinet machine, hang up can be, if the room layout is reasonable, you can also install a larger one in the living room, bedroom, small room on the small one, even not installed;

3. The direction of installation generally needs to be installed on the same side or side of the window, and as far as possible, it should not be facing the window, which will reduce the efficiency and consume electricity in vain.

4, brand, the domestic market high-end brand is Daikin, Kai, can provide both general cabinets, hang-ups, can also provide ** air conditioning, mid-range brands, such as Mitsubishi, Gree, etc., resist such as Guqiao, Galanz, etc., recommend Gree, moderate, the most important thing is that there is a 6-year warranty, and it should be replaced after 6 years, right?

When choosing an air conditioner, you must first know the actual area (length and width) of your room, and also know the height of your room, because air conditioning products have requirements for area, and will also have an impact on the heating effect due to the height of the room. Of course, it's a good idea to tell the salesperson as much detail as possible about the room before choosing a model, including: the orientation of the room, the window area, the various electrical products in the room (consider the heat production), and the function of the room (such as the heat match between the bedroom and the fitness room).

The next thing is to choose the model, the nameplate of the air conditioner product is marked with the nominal cooling capacity, for example, the nominal cooling capacity of the standard horse air conditioner is 3500w, as a consumer, the easiest way to choose the model is to match according to the family 200w square meters. For example: the room is meters long, meters wide, and the area is square meters, and you can choose KFR-32GW, which is a horse, and a half of a horse is smaller.

Household appliances, especially air conditioning products, one of the most important conditions is electricity safety, first of all, to see whether the product has passed the national Great Wall certification and 3C certification. Because air conditioning is closely related to people's lives, many air conditioners are placed in places within people's reach, and when there are hidden dangers, it is easy to have major accidents such as electric shock, short circuit, and even spontaneous combustion, which brings great trouble to the lives of consumers.

The next thing is to look at the quality, a good air conditioner first of all will be very fine, in addition from the condenser and evaporator production process can also be seen from the level of the manufacturer, good air conditioning products generally choose hydrophilic aluminum foil as the evaporation condensation fin, the advantage of hydrophilic aluminum foil is that the inner machine will not blow out mist water droplets into the room when refrigerating, detection method: water fin water, water close to the fin flow. The use of internally threaded copper pipe as the cold coal condensation sleeve can maximize the heat dissipation surface of the pipeline.

When the above homework is done, it is necessary to consider the brand, generally the domestic brand reputation is better, and the after-sales service mechanism is more stable and perfect. Although large brands are mass production, individual costs will be relatively economical than small-scale production, but first-line brands will still rise because of their perfect functions, better selection of raw materials, fine workmanship, after-sales guarantee and other reasons, so blindly pursuing low prices is not a rational choice, only high cost performance is the ideal choice.

A p is 13-17 square meters of 2500w pipe, is 23-27 square meters of 3500w pipe, and needs to be heated well to reduce 8-10 square meters on the original basis, and add a square (heating) for every 10cm of room super meter high, it is best to choose a first-line brand, such as Midea and Gree, the lower the energy efficiency ratio, the more power saving, but it also depends on **, choose the energy efficiency ratio is small, **low is the most affordable! Among them, the frequency conversion is the best, and the frequency conversion of Xiangmei has a ten-year warranty period (not a warranty) or it is more cost-effective!

Inverter air conditioner with unstable voltage can be selected for first-class energy saving in general families.

Domestic preferred Gree air conditioner: cost-effective, currently there are inverter air conditioners and fixed-frequency air conditioners; Inverter air conditioners should be selected with an energy efficiency ratio of 3 or above. Gree air conditioner has a cooling capacity of 3500W, and the rated power is 1100W, with a minimum of 100W.

Mitsubishi Electric air conditioner is selected abroad, but it is 20-40% more expensive than domestic air conditioner, that is, air conditioner. Refers to the process of adjusting and controlling parameters such as temperature, humidity, cleanliness, speed of ambient air in building structures by artificial means.

Generally, it includes cold source heat source equipment, cold and hot medium transmission and distribution system, terminal device and other major parts and other auxiliary equipment. It mainly includes pumps, fans and piping systems. The terminal device is responsible for using the cold and heat from the transmission and distribution to specifically process the air and temperature to make the air parameters of the target environment meet the requirements.

First of all, we should consider big brands, Gree, Midea is the first choice, and you can also choose a joint venture brand!

Look at the air conditioner with a heating capacity of 250 W per square meter for your room.

Gree, Midea and Mitsubishi Heavy Industries are all preferred brands, and now it is recommended to buy them like the unique fixed time in your home.

Air conditioning and refrigeration The effect is good, the heating is not good, if the single choice of refrigeration does not matter, the horsepower of the air conditioner is the cooling capacity, which is converted by electric power Half of the bedroom is like your home, 20 square meters, with 32 machines, a little larger, 5p 15 squares, with 26 of 6 squares, with 20 living room 40 squares, with 50 or 52 tracks, you can add up to your home down about 10,000 to give points!

20 square meters, buy a big horse hang-up;

15 square meters, just buy a small horse hang-up;

6 square meters, no need to buy it, buy an air conditioner in such a small place, there is no need for this, it's a bit of a waste!

Buy a 3 hp cabinet machine in the living room, after all, the space is large, and you need such a big air conditioner!

As for the brand, I see that I like it, and what I buy at home is Gree and Midea.

20 square meters to use horses (33 to 35).

15 square meters can be used for 1 horse or 1 horse (26 or 32).

6 square meters with 1 small horse (22 or 23) will do

As for the brand, first of all, Midea Gree Personally, I feel that Gree is slightly better, and Midea is not bad, but during the installation and maintenance in the summer, it was found that the copper pipe material used by Midea in some rural products was repaired.

The effect of Haier machine is also alive, there are many small problems, a lot of new machines are too noisy, if you want to choose other brands, you must be cautious, not to mention the maintenance cost, with trouble, no matter what brand, it is best to choose frequency conversion, fast refrigeration, low noise, I hope it will help you.

**Refer to the following** There are several differences in various places, depending on the local store.

Air conditioners are generally divided into window type, wall-mounted type, vertical cabinet type, mobile type, one-trailer type, ceiling type, etc., they have different characteristics, you should choose according to the actual needs of the family.

But I hope you can buy a brand-name ***.
