At present, due to global warming, people are using air conditioners more and more frequently, but not all users are familiar with the type and use of air conditioner refrigerants. The technology is getting higher and higher, and the parameters of the products are also increasing. Correspondingly, users need to worry more and more when purchasing. When buying an air conditioner back then, it was enough to look at the power and energy efficiency; but now when buying an air conditioner, you also need to look at an important parameter—the refrigerant model. Let me take you to know which is the best air-conditioning refrigerant to buy, and what are the types of refrigerants commonly used in household air conditioners?
First of all, let’s understand that R22 and R410A refrigerants are more familiar with air-conditioning refrigerants. However, because r22 has a certain destructive effect on the ozone layer, it is a transitional refrigerant. The R410A refrigerant derived later is also currently being used. Widely used refrigerant models.
Environmentally friendly refrigerant, refrigerant is also called refrigerant, isn't there so many pipes when the air conditioner is installed, and this is what flows in these pipes.
Refrigerant is a bit like gasoline. It has different components and different names. Gasoline has No. 92 and No. 95, and refrigerants include R32 and R410a.
Before we bought air conditioners, we had never heard of the word "refrigerant". It doesn't mean that it doesn't exist, but we often use another word to replace it—Freon, whose code name in the refrigerant is R22.
It was later proved that freon would damage the ozone layer and was not environmentally friendly. So a new batch of refrigerants appeared, among which R32 and R410a are the best. The current air conditioner has been banned from using R22 and replaced by R32 and R410a.
So, which of these two new environmentally friendly refrigerants is better?
What kind of refrigerant is required for an air conditioner to be fixed? It was R32 when I bought it, and I can only add R32 in the future—I regret it after buying it, and want to change it to R410a. Sorry, the air conditioner will break down. Therefore, the choice of refrigerant should be carried out when purchasing an air conditioner.
R32 and R410a
If you met a salesperson who bought an R32 air conditioner when you were buying an air conditioner, she might tell you that all air conditioners in developed countries use R32. This is true. Compared with R410a, R32 refrigerant has at least four advantages:
1. More environmentally friendly. Although the two refrigerants will not cause damage to the ozone layer, R410a has been proven to cause global warming. Although R32 also can warm the world, it is much smaller than R410a.
2. With less dosage, the working pressure of R32 is higher, which means that in the same size pipe, the filling amount of R32 is lower (only 70% of R410a). It can be compared to adults, 10 R410a can do the job, and 7 R32 can do it.
3. The cost is low. R410a is a mixed refrigerant, which is a mixture of R32 and R125 at a ratio of 1:1. It is more difficult to make, which will naturally lead to an increase in cost.
4. High efficiency. With the same air conditioner configuration, when R32 refrigerant is used, the working efficiency will be slightly improved.
In other words, for air conditioners with the same first-level energy efficiency, the price of the air conditioner using R32 is generally cheaper than that using R410a. But R32 has a huge flaw, that is, it is flammable. Do you still remember the news about the explosion of the air conditioner a few years ago: Once R32 leaks, the flammable gas comes into contact with the air, and if it encounters an open flame again, it will inevitably lead to an explosion.
Several explosion accidents discredited R32. So even if our craftsmanship and technology have been significantly improved today, R410a can still become a strong enemy of R32.
The above is the relevant introduction to which type of household air conditioner is generally used. Note that the air conditioner refrigerant must be filled according to the model marked on the air conditioner to avoid damage to the air conditioner system. If you have any questions about the type of air conditioner refrigerant, you can consult the relevant departments.
