It's getting hot, and a lot of friends have been asking about air conditioning lately. Some say, “one is more than a thousand hangers”, some say, “three cabinets are more efficient, one step in the way”, and others say, “some brands are too popular to buy it”。
It all makes sense, but buy it back, and regret it。
Since i've run an electronics store before, it's a good thing about air conditioning, and i've worked a lot with relatives and friends. Today, we're going to clean up the pits that buy air conditioning and save you some money。
Pit one: only the number of horses, not the room "hard wounds"
This is the most common problem. A lot of people measure the size of a ruler, and they're down against the table. As a result, it was discovered that the temperature in the house would not come down。
What's the problem? You're ignoring three "cooled households": sun, roof, window。
For example, a 15-m2 bedroom is enough with a normal one or a bigger one. But if this room is tanned three or four hours west of the afternoon, or on the top floor, if the roof is tanned in the summer, or if there's a big window down, the air conditioner can't hold it. The compressor kept running 24 hours a day, without paying for electricity, and the machine was easily broken。
How? On the standard number, you add half to one. 15m2 west sunbath, with 1. 5 direct; 20m2 penthouse living room, with 2 recommended for start-up. I'd rather buy a bigger one than a smaller one。
Remember the first point: the area is right, it's just a pass, and the window on the west tanning floor is the top priority。
Pipe ii: superstitious “first-stage energy efficiency” label, without apf numbers
First-level energy efficiency, of course, is good, but have you noticed that it is also first-level energy efficiency, with over 2,000 air conditioners, and four or five thousand
The key is not the word “level i”, but the apf value on the energy efficiency label。
Apf, in its full name, energy efficiency for the year, can be understood as 100 km of fuel for cars. Apf 5. 0 is the pass line for first-level energy efficiency, apf 5. 6 is the upper class and apf 6. 5 is the school master. The higher the value, the less electricity the same amount of cooling。
Some manufacturers can also mark a level 1 product with a 5. 0 line, but the actual electricity consumption is slightly higher than that of apf 5. 6. You spent an extra $20000 on the high apf, three or four years, and you saved your electricity。
There's another hole: don't buy a fixed-frequency air conditioner. It's cheap, but it's like an electric tiger, and it's cold and hot. The now fixed frequency is essentially inventory clearance, and unless the budget is really insufficient, it is bypassed。
Remember the second point: first-level energy efficiency represents a pass, and the apf figure is the real power savings。
Pipe three: ignoring installation, the perfect air conditioner is useless
It is true that many people say that “air conditioners are installed in 3-point mass and 7-point mass”. I've seen it several times, and the customers used to pay a lot of money to buy glycs and beauties, and it ended up having a bad cooling effect, high noise and leaking water. It's all about installation。
A few key installation details, you must keep an eye on:
Vacuum: vac must be pumped for more than 15 minutes with a vacuum pump. Some masters take two or three minutes to pull out the tube or not. The refrigerants in the air conditioning thus mix the air, the cooling effect is reduced and the compressor life is reduced. You just stare at him and don't sign for 15 minutes。
Outer space: the outer space is best placed in a ventilated area, not in narrow shutters. The heat spread is bad and the cooling is still running out. If the location reserved by the developer does not work, let's talk to the installer about changing it。
Bronze length: the piping is three metres in length, and if your external aircraft is far from the inside, extra money is required. Ask in advance how much one metre is, and don't wait for the price to be increased。
Remember the third point: buying air conditioning is just the beginning, and it's not good enough to buy it for nothing。
Q: buying a tile cheaply, selling it to cry
Some people think, "current air conditioners are the same. Two thousand dollars for a three-piece machine? There's such a cipher on the internet。
But think about it: air conditioners work very hard every summer, compressors, fan engines, circuit boards, which are troublesome. The network of miscellaneous air conditioners is low, there are no telephone calls and spare parts are difficult to find even if they are repaired. Two hundred and three hundred at a time, two times enough for you to change your brand。
What about the mainstream brand? A simple reference:
Glig: good work, but expensive, suitable for a well-budgeted budget。
It's beautiful: it's worth a lot of money. It's a lot of money。
Haile: the service is good, but the price is slightly higher than that of the united states。
Millimetres/wallows: the price is high, and more than 2,000 can be purchased with a first-level energy efficiency of 1. 5, suitable for young people with limited budgets seeking smart linkages。
Tcl/ox/rain: second-line brand, cheap, but uneven, not unbuyable, psychologically prepared。
And remember the fourth point: to save the beauty of hearts and minds, gly, hail; to value more than to choose millet and valor; and not to touch the cards if they are cheap。
Pipe five: paying more for the flair
There are too many air conditioners now: new wind, debacteria, voice control, infrared sensory, light sleep ... Sales say smallpox crashes, as if they were not bought。
But you calm down: do you really need it
New wind function: if your house is always open, there's no need. It's more than a thousand times more expensive than normal air conditioning, and it's very small。
Voice control: now that dozens of dollars buy a smart speaker, the air conditioner will be able to control the voice
Absorption/purification: general ac filters are enough unless there is a home-sensitive person。
Light sleep: automatic syllables, lower wind speed, a little, but not just needed。
There are two additional functions that are really practical: protection from brawling (friendly to older people and children) and self-cleaning (so that you don't have to do it in five ways). Other functions, budget availability, and budgetary constraints could be abandoned。
And remember the fifth point: how much of a function does not mean good, it's practical。
Summarizing: buying air conditioners to remember the five holes
One, a window on the west tan top floor, and a half-barrel。
The first level of energy efficiency looks at apf, and the higher the number, the less electricity。
3. Installations to keep a close eye on the vacuum and external ventilation to fill。
Don't touch the cards if they're cheap。
5. Direct blowing and self-cleaning, other functions looking at wallets。
