Unknowingly arrived in June, this summer in Guangzhou seems to have come very early. Summer, average temperature of more than 30 degrees, what cool can help us to spend the summer? The answer I think there is only air conditioning. One piece of the story was, 'In such hot weather, my life is air-conditioned!' (laughs) But when you start using air conditioners, it is estimated that there are a lot of young friends who have such questions: Why is my air-conditioning not as good as last summer? The power to the?
'Not to force' is a popular saying. The professional saying is that the cooling efficiency of air-conditioning is not as good as it used to be. There are many reasons and some misunderstandings.
Misunderstanding: Not cold is not necessarily a lack of refrigerant
Many of my friends will have the illusion that after a few years of air-conditioning, when they find that air-conditioning cooling effect is slow one day, they will mistakenly believe that the refrigerant is not enough. When you call after-sales service, some Good maintenance Master will add refrigerant to you only after a simple inspection. As time goes by, let's mistakenly believe that the air conditioning is not cold is the cause of the refrigerant.
In fact, a large part of the air-conditioning cooling efficiency is the reason why the filter screen is dirty. When the indoor air conditioner filter and fins accumulate more dust, it will seriously affect the air-conditioning outlet, thus the cooling effect, and the dust Accumulation also tends to breed bacteria and has a negative impact on health.
For this, our PConline appliance group also made a test, the goal is our home appliance evaluation room air conditioning!
Our test today is also a demonstration of how to clean the home air-conditioner. The focus is on cleaning air-conditioning filters. There are already many articles on air-conditioning filters on the Internet, but most of them are wall-mounted air-conditioners. Once, we 'don't take the unusual road' and take the vertical air conditioner 'room' of the evaluation room.
The cover of our vertical air conditioner is fixed with screws (many air conditioner covers are snap-fit, so you only need to lift the cover upwards). First open the screw covers on the left and right sides. Lower the screw, and then use a little force to remove the cover.
Take care when removing the cover, because the cover's display and buttons are connected to the power cord inside the air conditioner. Carefully pull the clamp in the middle of the power cord, and set the cover aside, you can pull out the filter It!
Really do not know, look surprised! Really did not expect that there will be so much dust and rubbish adsorption on it! Because our air conditioner on home appliances evaluation room less than a year, and just come When the evaluation room is used to evaluate the product, it will only be turned on. There will be so much dust, so I can't help but guess what the air-conditioning filter used in the home is dirty.
And so much dust has blocked the filter screen, and it cannot guarantee that it can filter clean air, so it is also harmful to health.
After removing the filter, we can see that the inside of the air conditioner and the frame part are also dirty. At this time, we can use a damp towel or dry towel to wipe the air conditioner and wipe off the dust. Because the air conditioner has a circuit board and a lot of elements inside. Device, so be careful not to get water when cleaning.
The cleaning of the filter is not so particular. Just clean it directly under the faucet. When cleaning, pay attention to the concave side of the filter and the convex side to the bottom so that the dust can be easily washed away. Because the dust is absorbed. In the thick layer above, it is difficult to rinse clean, this time you can use a brush, simple and efficient.
After cleaning, remember that it cannot be used directly because there is a lot of water. In the process of drying, try to avoid sun exposure. Because the filter is a plastic product, it is very easy to dry it. It only needs to be dried in the shade. After air drying, you can install air conditioning!
After cleaning the filter, we re-opened the air conditioner. Everyone felt that it really felt that the air-conditioning was more powerful. Of course, it could also be the result of a psychological suggestion. However, it is certain that there are so many filters washed out. After the dirty things, this home air conditioner is indeed a lot of psychological comfort.
So here we also suggest that you have the time, you can also remove the home air conditioning filter to clean, although the actual effect should be based on the degree of filter clogging to decide, but give people a psychological improvement is obvious.
