How much is an air conditioner plus fluorine? The industry’s statement and the price offered by the maintenance workers are ten times different, while journalists find in their covert interviews that different maintenance shop owners have different offers。
Air conditioning and fluorine. Eye
According to the shandong radio and television living channel, journalists have visited randomly several electric repair shops in zinan, suggesting that domestic air conditioning needs fluorine, but different shop owners have proposed various ways of charging fees。
Upon enquiry, journalists found that the fluorinated method was roughly divided into four categories by merchants, plus the number of air conditioners plus the pressure plus the number of kilograms of refrigerants. As a result, there was a dramatic situation, as well as fluorinated fluorine, where an air-conditioning unit could produce four prices in four ways。
In an electrical repair shop, the owner indicated that the air conditioner was fully fluorinated, charging 80 units to the table and, if under pressure, a pressure of $30. In this way, the same air conditioner shows two prices。
The owner of the electrical repair shop also admits that there's a doorway, "the stage, the pressure, yes, you press the table, no matter what, give you 80, you press the pressure, you get more money."
Expert: fluorinated and unstandardized
This situation is not only confusing, with a fluorinated air conditioner at multiple prices. So, what is freon and why is there so much added
Professor han of shandong university told journalists that freon was also known as freon, hydrochlorofluorocarbon (hcfc) (ting). In order to reduce atmospheric pollution, such as r22, cfc-12, which is the sum of several fluoromethane and chloralethanes, r410as have been introduced in non-fluorinated air conditioners in recent years, which are used as a cooling public and are not consumed without disclosure。
An air conditioner plus fluorine, the same air conditioner, can add four prices in four ways, which is interesting. So, how does this freon work
Professor yamada: best scientific fee based on refrigerant injection
In many electric repair shops, the owners offer different ways of increasing the price of fluorine, and an air conditioner can add different prices in different ways. So, how much freon does an air conditioner add? Professor han indicated that an indicator of the type of refrigerant and the amount of injection can be found on either the interior or the outer side of the air conditioner. At mr. Zhang's house, on the side of a united states-sized air-conditioning indoor machine, it can be seen that the refrigerant type is r22 with an injection of 620 grams。
Han jida, director of the institute of refrigeration and low temperature engineering, shandong university: “a kilo of money is paid for the quality of the refrigerant, plus one kilo.”
In this way, it is easier for consumers to understand the notion of a fee based on the number of stations or air conditioners, which is more clearly based on the addition of kg of refrigerants, but what is the theory based on pressure
Professor han stated that in a certain temperature environment, fluorinated fluorine would produce a certain saturation pressure, and the pressure in the air conditioner would certainly change as the refrigerant entered. For example, if an air conditioner was not empty, the pressure sheet could be consulted, but in practice, the price of a pressure was usually fixed by the merchants to tens of dollars, but the pressure was not fixed when it was actually applied to the pressure table。
Air conditioner fluorine turns to conscience work
The electrical maintenance engineer wang told reporters that the pressure on fluorine was changing with external temperature, that the high pressure on temperature was higher, that the low pressure on temperature was lower, and that air conditioning itself could change the pressure even if the external temperature remained constant。
Thus, according to a charge of several dozen dollars for a pressure, which is difficult to fix per se and which is based on a scientific basis, it becomes a life of conscience in its practical application, which is confirmed in the mouths of many air conditioners。
It's hard to see how there's so many channels for simple air conditioners. Experts have also told you that, while there is some reason to press fluorine, when applied in practice, it changes the conscience of maintenance workers. First, the pressure can change more in line with the temperature of the external environment; and second, the pressure rises when it is not open, and even the looseness of the chain interface can change the pressure. For these, ordinary consumers simply don't understand。
