Chengdu's been really hot lately. He wanted to write a guide to the refrigerator. Think about it。
The climate is getting hotter and hotter in the first 10 years, and air conditioning has been evolving for decades, and in the case of air conditioning alone, the choice of brands is not going to buy high-value products。
Today's article is a detailed account of the sale of cabinets and hangers。
Pre-purchase notice
Before writing specific procurement parameters, i would like to write a few points of focus, which, if not, would make it easier to pay $10,000 for a hanger。
The hanger must be 1. 5
A lot of friends around me ask me what an air conditioner would do. Remember, don't pick an air conditioner
First, the difference between one air conditioner and 1. 5 air conditioners is around 200, and the difference is very small. Second, there's a huge gap between one air conditioner and 1. 5 air conditioning。
For example, a 1. 5-piece version of net red bull, n8he1, with a 2-branched copper tube, and a single-branched copper tube. The various configurations shrunk and were worth well over $200。
Some might ask if 1. 5 is too big and too small to be too cold? The answer is no. The current air conditioner is already a frequency that automatically adjusts to the temperature of the room and does not appear as cold as the old air conditioner。
Watch out for prison space
The problem of slots is most easily overlooked in the selection of air conditioners (whether they are hangers or central air conditioners)。
There are now widespread high-level residential buildings, coupled with a deteriorating climate, a peak temperature of 40 degrees or higher in the summer, and a much worse operating environment for air conditioning, which can easily trigger "high temperature protection"。
Worse still, if it's sun in the west, or if it's a dove cage like this, or if it's dented, the air conditioning environment is worse, and the temperature can be as high as 50-60 degrees。
At this point, you're going to have to choose the outside with heat-dispersion technology。
What parameters to hang up
For the sake of simplicity, i have divided the key parameters into core parameters that affect performance and core parameters that affect comfort effects. Before talking about these two parameters, we start with the most basic and intuitive apf。
Apf
The apf energy efficiency level is an indicator for the evaluation of air conditioners implemented by china on 1 october 2013 to assess the efficiency of energy consumption throughout the year. People say that the higher the apf, the better it is。
The way to upgrade the apf is mainly stacked, so the higher the apf value for equipment with the same cooling volume (e. G. 1. 5 air conditioners), the higher the relative configuration。
At the current time, 1. 5 air-conditioning units apf 5. 28 are used to calculate the base entry, 5. 3-5. 4 are used to calculate the middle end and 5. 6 are considered to be high performance。
Bronze platoons that affect core parameters of performance
Conclusion: two sets of condensers preferred。
The effect of external copper tubes is to achieve temperature exchange through the anti-kano principle, and the greater the number of copper tubes and the larger the area of heat exchange. In human terms, the experience is that it is colder and less likely to cause high temperatures to stop。
General household air conditioners are subject to cost limits, and the number of copper tubes outside air conditioners is highly differentiated. Again, for example, the external copper tube can cross the single row, 1. 5 rows and double rows in three slots。
So in today's summer-long super-temperature weather, the choice of air conditioners has to be a double-team condenser, which is more likely to ensure cooling. More than 1. 5 units are basically double-detached condensers, the difference being copper tube density. It is very difficult for us to understand the performance of the counterpart product from the detailed pages and the client service。
There's a little trick here: to see the amount of material by the weight of the outside machine. For example, mi's base of three cylinders is called "gross power" and is divided into two small versions of "gross power" and "gross power pro"。
The net weight difference between these machines is 1kg, and the copper tube plus the wings can add a lot. If you cross-brand, for example, look at a beautiful quiet wind three, the outside weight is 43kg。
External heat diffusion technology
Conclusion: refrigerated rings。
We started by talking about the problem of prison space, and the most important thing to solve this problem is the heat-dispersion technology from the outside。
But if you look at it carefully, you'll find that all the major brands on the market now have a "xxx-xxxx" cryogenic high temperature. In practice, however, high-temperature refrigeration technologies are also good and bad。
The normal high-temperature refrigeration technology is the optimization of windways and external flow tissue, increasing the heat resistance of the main plate, etc. Does this upgrade work? It works. However, it is not representative of the fact that the heat of the summer does not stop. It's still working when it's hot, but it's too hot to believe。
How do you choose air conditioners with high-temperature refrigeration technology? The best effect at this time is the cold ring technology (also referred to as liquid cold). In humans, the copper pipe of the air conditioner was used to lower the temperature of the main plate with a cooling pipe. The advantage of this technology is that external aeroconditioning decay is limited at relatively high temperatures, where performance remains constant and at very high temperatures。
How do you know if the machine has a cold ring technology? For the time being, the brands with this technology would have written it into the detail pages, and if it was as ambiguous as the ones below, it would have been accepted directly。
Inner wind wheel diameter and wind volume
Conclusion: air conditioners 100 mm diameter preferred for fans, followed by air-conditioning winds。
Do internal wind turbines affect performance? Yes。
The internal and external air-conditioning units are used to blow the evaporation unit in order to exchange cold and heat, so the faster the heat exchange, the better the performance. But besides simple performance, the inner machine has to take into account the noise, so it can't increase fan power like the outer one。
So the inside of the wheel is the best answer to the current version. It is said that when the area of fan leaves increases, the number of fan slots is neither large nor cool。
In choosing air conditioners, attention was paid to two parameters in the detailed pages. The first is the diameter of the pouring fan, and generally over 100 mm is a pouring fan。
Second, with regard to internal wind, some air conditioners may have been designed for different focus, but not on the detailed pages. And here you're choosing air conditioning above 750, so basically you won't step on the pit。
Parametric winds that affect comfort board
Conclusion: general steering panel, practical, good-use software, positive software, presented by a few
