Turning on the electrician platform to select air conditioners, it is believed that many will find a confusing phenomenon: a 1. 5-mounted hanger with a very high price range. The entry price for the mini-air conditioner activity was around $1,800, while the general price of the same specification glycotype was $3,200, with a difference of up to $1,400。
A lot of consumers reacted first: not all of them were 1. 5. Refrigeration was about the same. Is it just a brand premium? Some people think low-priced air conditioners are "slice-cutting" and that they can be very expensive. Both extreme ideas are not objective enough。
As a long-term producer of all types of digital power, i have been exposed to hundreds of air conditioners, and i have seen the rental party's long-standing use of 1,000-dollar air conditioners, as well as the choice of high-end hangers by the home owner. The real gap between the hardware materials, the core parts, the r & d schools, the installation and sale, and the application of the multiple dimensions of the scene today is clear, leaving aside the business jargon. After that, you don't have to be blind or windy and choose rationally in keeping with your needs, avoiding buying expensive or stepping on a pit。
First to correct the maximum error: “1. 5 tablets” are only generic and not directly equivalent
The vast majority of ordinary people buy air conditioners, the first big pit that is the easiest to step on: just look at the numbers and ignore the key parameters。
The term “pis” in the industry is in itself an informal unit that is used only for rough representation of refrigeration capacity. Under the new national marker, the regular 1. 5-mounted rated refrigeration area is approximately 3300 w ~ 3600 w. Also called 1. 5, there is a gap between the maximum and the lower limit of refrigeration itself。
Most of the entry-level air-conditioning at a market value of 1,800 dollars is stuck to the minimum threshold of 3300 w, while the 3200-stee glyco-main type is generally rated at 3,500 w to 3600 w. Looking at the digital divide is small, but the difference is clear in the physical environment。
If the room is equipped with a roof, sun, large windows, with a sufficiently large cooling capacity, the temperature of the high-temperature environment is reduced faster and the compressor does not need to operate at full capacity for a long period. Smaller residuals of cooling machines are exposed to high temperatures and are prone to slow cooling, continuous high-loading and rising electricity consumption。
In addition to refrigeration, the apf-yearly energy efficiency ratio is also a key point in opening the gap. Similarly, energy efficiency at the first level, the apf values are high and low. Low-cost machines are able to achieve a level-i energy efficiency, but parameters are near the eligible line; higher-end apf values are higher and are used over a long period of time, and the difference in electricity costs is slowly apparent。
Here you are reminded that the selection of air conditioners should not only look at 1. 5 tableds in the title, but rather at the top of the list, with detailed pages checking the rated cooling and apf efficiency values, which are more specious than the scales。
Ii. Dismantling of core hardware: what is the difference between the price of $1400 and the cost of hardware
The air conditioner is good. The outsider is in charge. Inner machines determine the use experience, outsiders determine cooling efficiency, noise, long-term life, and are also the areas with the largest gaps in producer cost inputs. We focus on three core components。
Compressors: “heart” for air conditioners
Compressors are the most costly parts of air conditioning. For decades, a large number of aircraft have been mounted in the guly deep till air conditioning industry from the ringda compressor, which is charged with long-term calibration and operating areas to support wide-temperature operations. High-temperature outdoors and cold winters provide greater operational stability。
The main rice entry-level 1,800-bit air conditioners, mostly using external third-party compressors (mizzi, hailey, etc.). Third-party compressors are qualified for daily base use, but brands do not have autonomous proofing authority and use generic programmes。
A brief summary: basic refrigeration can be achieved, long-term limit operating, and self-study custom compressors have a higher stability ceiling. The difference is not easily felt in day-to-day bedroom temperature and environmental use; stability differences are slowly reflected in chronically high temperature areas and long periods of continuous operation。
2. Resilient devices: electrostatic expansion valves vs hair tube, critical
Many ignore this little part, but it directly affects temperature accuracy and electricity consumption。
A 3000-bit glyph type of 1. 5 variants with basic standard electron expansion valves. It regulates the flow of refrigerants according to indoor temperature, which is dynamically precise. The indoor temperature is less volatile than the heat; under heat-making, high-temperature refrigeration is more efficient and less efficient。
Partially $1,800 low-cost open-frequency air conditioner, with a cascading throttle. The catheter structure is simple and less costly, and the flow of refrigerants is fixed without dynamic regulation. Normal use is no problem in a stable environment, but under extreme temperatures, efficiency is reduced, temperature control accuracy is weak and room temperature is highly volatile。
3. Condensers (dispersible copper tubes): the difference between single and two rows
The copper tube heater in the outside machine is responsible for heat dispersion. Thermal dissipation is good and bad and directly affects the ability of high temperature air conditioning to operate steadily。
The higher-priced glycerator type, many of which carries double-team condensers, with a larger area of dissipation, and the 1,000-dollar first-stage air conditioner, many of which uses single-team condensers。
When outdoor temperatures exceed 38°c and 40°c in the summer, the single-dispersion heat pressure is greater, compressors are more likely to trigger high-temperature-reducing frequencies, and there is a phenomenon of “air conditioners operating long hours without cooling down rooms”. The gap between daily spring and autumn, and between warm and weather use is difficult to feel。
In addition to this, there is a cost distinction between outer-hull steel plate thickness, rust-proof coating, and fan electric utility, with different price types. The cost is reduced by one cent and ultimately reflected in the final sale price。
Software calibration, functional experience: different positioning, completely different focus
The greatest highlight of small-scale air conditioning is intellectualization. The 1,000-dollar price machine type is generally fitted with wifi connections, which can access the rice family ap, remote switches, connections to intelligent homes, such as the automatic opening of air conditioners, and wetners, and purifiers. For young people who are used to house-wide intelligence and like mobile phone manipulation, this is a big deal。
However, it is objectively acknowledged that millet starts later and air-conditioning systems accumulate for a relatively short period of time. Gravity has been in the refrigeration laboratory for decades, with extensive debugging of wind speed, temperature control algorithms and temperature and humidity balance。
This is reflected in daily experience: frequent high-end glycerine-type soft wind technology, straight-blow precision control, lower-run noise optimization. In the same environment, high-cost machine-type temperature control is softer and noise control is better at low wind speed at night。
Of course, intelligence is not absolutely good or bad, and different choices are required. If you only want a simple cooling air conditioner, and you don't need a smarthouse connection, the smart function is an optional configuration for you。
Production patterns, channel costs: also an important source of price differentials
There is a lot of doubt as to why the price on the millet line can always be lower, and here there are two branded business models。
The majority of small-scale air-conditioning is based on the proxy model, which is sold through a line-on-line electrician channel, saves a large number of lower-line rentals, higher prices for distributors, lower channel costs, and is heavily marketed, targeting renters and users with limited budget。
Gwi has its own large production base, its core parts are produced independently, and it has a network of shops and distributors covering the entire country. Under-line rents, sales staff, and profits from multiple distributors are distributed among product sales. The system of offline and offline prices determines that base pricing is difficult to achieve at very low prices。
The two models are not good or bad, but they serve different populations. Online brands compress the middle to the benefit of consumers; traditional large firms rely on offline sites in exchange for greater localization of services。
V. Implicit costs that are easily overlooked after quality assurance, installation and sale
Air conditioning is a “triple product, seven-point installation”, and the installation process directly determines the effects of use。
With regard to quality assurance policies, it is common to have a 10-year free-of-charter policy in place for the main gree hanger, and a six-year package for the majority of the millet-entry type (a 10-year charter for the upgrade of the new component, which requires careful checking of the commodity pages before purchase). Differences in quality assurance time mean different maintenance safeguards for long-term use。
See also the installation of the network: for the next few decades, the gry-deep crop line has co-selled after-selling sites in towns and counties throughout the country. In many remote areas, the rate of post-sales response is more stable. Rice is sold mostly by third-party service providers, with first- and second-line urban service experience and gaps in net coverage in some remote areas。
Here is a useful reminder: the purchase of air conditioners does not depend solely on the price of the machine, prior confirmation of the installation fee, the cost of high altitude, stubbles, and long copper tubes, with different brand rates。
Highlights: who are the two types of air conditioners? Don't buy it blindly
After looking at the hardware and after-sales gap, one does not simply decide that “a certain amount of value, which is cheap, cannot be bought” and combines the rational choice of the place of residence。
About $1,800, 1. 5 air conditioners for millet
1. Rental housing, with an approximate rate of relocation over the next three to five years, with no intention of permanent use
2. Within 15 m2 of the bedroom area, the household temperature is good, with no sun or roof
3. The use of time is mild and does not last 24 hours throughout the summer
4. A home full of rice smart houses requiring air conditioning access to eco-links
5. Limited budget with priority given to meeting basic refrigeration heat needs。
Not suitable: top floor, large area of sunflower, long-term all-weather high intensity, intended for more than 10 years。
3,200 stairwells, 1. 5 hangers for this group
1. Home ownership, renovation of long-term settlements, with air conditioning planned for 8 to 10 years
2. Bedroom 16-22m2, penthouse, west sun, ground window, heavy refrigeration load
3. High level of night noise, temperature comfort control and long-term nighttime air-conditioning sleep
4. The long-term durability of the whole machine after heavy long-term quality assurance and steady-line sales
5. Do not change household electricity frequently and are willing to invest more in advance in exchange for a long-term stabilization experience。
Seven, pick up some air conditioners and give them advice
1. Not simply price, different configurations of the same number cannot be directly compared, with priority given to cooling volumes, apfs, condensers'structures and current-saving devices
Level i energy efficiency is also low and the higher the apf values, the longer the use of electricity, the longer
3. Long-term high-loading, with priority given to external configuration; short-term transition without blind pursuit of matching
4. Validation of quality assurance years prior to listing, installation of charges, avoidance of low-cost purchasers and later installation of price increases
5. A rational view of the brand premium does not have an absolutely perfect product, and it is the best value for money that is suitable for its own use。
