What are the tips for choosing air conditioners (how to choose air conditioners? Look at these five points)

How to choose air conditioner? What parameters should I pay attention to when buying air conditioners? Now there are too many air-conditioning brands to choose from in the market, and new functions and products emerge one after another, which really makes people shine.

Today, I will talk to you about buying an air conditioner. Generally speaking, there are three kinds of common household air conditioners: one-wall air conditioner, cabinet air conditioner and one-N central air conditioner. If you have a budget and a large room at home, you can choose to install central air conditioning for the best comfort. For ordinary families, it is common to place cabinet air conditioners in the living room and install wall-mounted air conditioners in the room. When we choose, we mainly look at these five points:

First, the number of people:

The first thing to determine when buying an air conditioner is how many air conditioners you want to buy. What's the difference between these so-called 1, 1,1.5,2 air conditioners? Let's just say that the number of air conditioners refers to the input power of air conditioners, and one air conditioner =735W, which is determined by conversion.

This number affects the cooling or heating effect of our room. Generally, we choose the corresponding air conditioner according to the room area. Suggestion:

10- 17 room: 1 room 15-23: 1.5 room 23-34:2 room 32-48:3 room 57-88:5. If your room is small, there is absolutely no need to buy two air conditioners. On the contrary, if your room area is relatively large, don't buy an air conditioner just to save money, which has no effect on cooling or heating.

Second, the fixed frequency/frequency conversion:

Fixed-frequency air conditioners have low cost, so their prices are generally lower. When we use a constant frequency air conditioner, we often stop working after setting the temperature, and then start it again with the change of room temperature, so the compressor needs to be started and stopped once to keep the indoor temperature constant, which makes the indoor temperature feel unstable and makes people feel bad. However, even so, the fixed frequency air conditioner is still liked by many people, mainly because it runs stably and rarely breaks down. But now few fixed-frequency air conditioners are sold.

You don't have to-don't worry too much. Basically, 95% people can only buy inverter air conditioners. Frequency conversion air conditioner will be more expensive than fixed frequency air conditioner. After all, the compressor price of inverter air conditioner is 1.2- 1.5 times that of fixed frequency air conditioner. Inverter air conditioning will bring a more comfortable experience and the temperature fluctuation will be smaller. It has one more frequency converter than the fixed frequency air conditioner. When the set temperature is reached, the air conditioner will run at low power and adjust the corresponding temperature according to the actual space temperature to stabilize the indoor temperature.

Three: energy efficiency ratio/energy efficiency grade

The energy efficiency rating is that the smaller the number, the better. Generally divided into new level, level 1, level 2 and level 3. Among them, the new 1 class energy efficiency is the latest international energy efficiency standard in 2020, with the best energy-saving effect, and of course the corresponding air-conditioning price is also the highest. The energy efficiency of products below grade 3 is far below the market average, and production and sales have been banned.

When checking the energy efficiency rating, the product front panel on the air conditioner is often labeled. You can notice that it is marked quot. The China energy label is at the top.

In addition, the energy efficiency ratio of air conditioners is that the bigger the number, the better. Energy efficiency ratio, which literally means energy conversion efficiency ratio, won without introducing complicated explanations. Just remember, we mainly look at the refrigeration energy efficiency ratio, that is, the refrigeration capacity per unit power consumption. The higher the energy efficiency ratio, the more energy-saving the air conditioner is under the same refrigeration capacity.

However, it is worth mentioning that there may be a virtual standard of energy efficiency, even some well-known brands of household air conditioners in the market are no exception. The new national standard issued in July last year put forward higher requirements for the energy consumption of air conditioners. Products that do not meet the new national standard are not allowed to be sold, and manufacturers are forced to falsely improve the energy efficiency ratio of air conditioners.

With the development of science and technology, air-conditioning products are updated iteratively, and more and more new functions are available. However, not all functions are practical, and some functions are just to create gimmicks, attract attention and make the products more expensive. Let me talk about the functions that I think are more practical and impractical. Of course, everyone's needs are different, and you can choose the one that suits you according to your own needs.

Practical function: refrigeration; Heating; Dehumidification; Support up, down, left and right sweeping to prevent direct blowing;

Chicken ribs function: self-cleaning function; Purification function; In addition to formaldehyde, except PM2.5；;

In fact, air conditioners are mainly used for cooling and heating. As for those smart WIFI controls, voice, etc. Including the chicken rib function mentioned above, I think it is far from practical to pay more attention to the refrigeration and heating effect of air conditioning and adopt any technology.

Fourth, the function:

Among domestic brands, Midea, Haier and Gree basically occupy half of the country, so you can choose from them.

Under the leadership of Dong Mingzhu, Gree Air Conditioning is basically a household name. Gree's research and development ability is good. D strength, and has its own compressor brand 3354 Lingda compressor, which is the first batch of production and research in China; The quality control of air conditioning compressor is quite good.

Although Midea only plays once a night and is suspected of false propaganda, it is also outstanding in technology because of its early cooperation with Toshiba. Its own compressor brand and motor brand are also quite famous in the industry.

Although Haier does not have its own compressor brand, it entered the air conditioning field earlier and cooperated with Mitsubishi Heavy Industries in the early stage. In this field, technology accumulation is also very rich, air conditioning quality control is also very possible, and after-sales service is also perfect.

Japanese brands such as Panasonic, Hitachi, Daikin, mitsubishi electric, Toshiba and Fujitsu are the best-selling brands. Mitsubishi's installation service is very good in the industry. The so-called three points depend on the product and seven points depend on the installation. For central air conditioning, Daikin is recognized as the first in the industry. In a word, the brand of air conditioner is very important, which also determines the after-sales service.
