Text/Appliance Evaluator Andy
Whether the new house is equipped with air conditioning, or the old house is replaced with air conditioning, many people simply look at whether it is "fixed frequency" or "frequency conversion" when purchasing, or whether it is "first-class energy efficiency". As a matter of fact.
There are many manufacturers and brands, and the product models of air conditioners are also mixed, which is actually easy to step on at this time. In this issue, Andy combines years of experience in home appliance evaluation and the lessons of replacing multiple air conditioners to summarize 4 kinds of air conditioners that may be eliminated!
1. Air conditioners that cannot resist high temperature
"What, air conditioners are also afraid of heat"?
Perhaps many people do not know that although the core function of summer air conditioning is "cooling", which turns high temperature into low temperature, it is also "heat-sensitive".
I believe that many netizens in "stove" cities feel the same way. What's going on here?
Actually, this is because. This is similar to electric water heaters, hair dryers and even mobile phones. (For example, mobile phones, when too hot, will automatically black screen, turn on overheating protection)
In some areas, the summer temperature is as high as 40 °C, if the location of the air conditioner external unit is not ventilated, or it is not conducive to the heat dissipation of the external unit, the ambient temperature of the external unit is likely to exceed 50 °C. According to the national standard, the air conditioners shipped by many manufacturers in the mainland have an external unit withstand a temperature of 43 °C. This means that once this value is exceeded, it will seriously affect the operation of the external machine, and even the situation of downtime will occur.
According to Andy's understanding, at present, air conditioners in the domestic market, ordinary air conditioners are still mainstream, and only a small number of manufacturers have launched "high temperature air conditioners".
The "high-temperature air conditioner", because it can withstand a high-temperature environment of 50 ° C or even 60 ° C, so the probability of downtime will be greatly reduced. Predictably,
2. Air conditioner with relatively high energy consumption
I don't know if you have found that there are still many high-energy-consuming air conditioners on the market today, and they are mainly filled in rental housing. In fact, from the perspective of economy, high-energy air conditioning does have its advantages.
After all, most of the air conditioners with high energy consumption are three-level frequency conversion and five-level fixed frequency air conditioners, and the input cost is generally low, such as three-level inverter air conditioners, which can basically be done for about 2,000 yuan, and even single-cooling air conditioners with five-level energy efficiency can be won within 1,500 yuan.
Low input costs, why is it gradually being phased out?
The obvious reason for this is naturally the problem of "energy consumption". Because the energy consumption is too high, the "cost of use" of this type of air conditioner is relatively high. The word "electric tiger" that has become popular in recent years is actually derived from high-energy air conditioning.
Even in the rental housing market, high-energy air conditioners are bound to fall off the altar, from the perspective of tenants, if you live for a long time, it is better to use high-energy air conditioners than to choose first-class energy-efficient air conditioners. (Especially the older generation of fixed frequency air conditioners)
According to the data surveyed by Andy, air conditioning manufacturers are also getting more and more rolled, making the price of low-power air conditioners with primary energy efficiency and secondary energy efficiency lower and lower.
3. Air conditioning with R32 refrigerant
There are many types of air conditioning refrigerants, aside from the R22 that has been eliminated, the mainstream refrigerants on the market are currently divided into two types:
(1) R32 refrigerant; (2) R410a refrigerant.
For ordinary users in the non-air conditioning industry, few people understand the difference between air conditioning refrigerants. In fact, it is very necessary to understand the types of air conditioning refrigerants. Next, Andy will talk briefly.
Many domestic air conditioning brands basically use R32 refrigerant. "If everyone is using it, is it necessarily worth investing"?
Not necessarily.
R32 refrigerant does have its advantages, such as its low cost (manufacturers are also willing to use), less dosage, and also has certain advantages in environmental protection and refrigeration efficiency.
However, it must be admitted that air conditioners using R32 refrigerant are relatively easy to explode (the main component is difluoromethane, and the explosion limit is 14.4%-29.3%). Not nonsense, but a lesson learned over the years! I believe that everyone sees the news of the explosion of the air conditioner every year, which is ultimately caused by the characteristics of this refrigerant.
In contrast, R410a's refrigerant, as a new type of environmentally friendly refrigerant, was once considered the best alternative to R22. It differs from R32 in that it is a hybrid formulation (a combination of R32 and R125) that is stable, non-toxic and non-flammable. However, it must be admitted that R410a refrigerant does not have a cost advantage.
In addition, in terms of refrigeration efficiency, R410a and R32 are not much different, although the amount of R32 is small, but the exhaust temperature is higher than the former.
4. Air conditioner with poor product strength
As a large piece of home appliances, air conditioners are invested in thousands, and tens of thousands are invested, and whether the quality is passed is the most critical. Throughout the entire air conditioning market, there are many brands and uneven product strength.
What is "Product Power"? Simply put, the manufacturer has excellent technology and a solid production line, which makes the "defective rate" of the produced air conditioner extremely low. It must be admitted that some small and miscellaneous air conditioning companies in the domestic market do not have product power. Therefore, when purchasing, try to consider "old domestic products".
In other words, air conditioners from niche manufacturers, do not invest. It does not have any advantages in product strength, and it is also very chicken in after-sales service. On the other hand, those first-tier air conditioning brands are trustworthy. For example, the old air conditioner Gree, Hisense, Oaks, Haier, Kelong, Hualing and TCL and so on. Of course, new Internet air conditioning brands like Xiaomi can also be considered.
More [home appliance topics], welcome to pay attention, we will talk about which air conditioners can be called "magic machines" in the next issue!
