1 thought on “How to look at the second -hand air conditioner is greasy”

1. It is best not to go to the second -hand furniture market to buy second -hand air conditioners. This is an experience. But the premise is that you don't understand the electrical appliances, not an expert. Because most of the electrical appliances in the second -hand market have been used for many years, some parts have been repaired. It is difficult for non -professionals to judge quality. 2. A good way to recommend is to pay more attention to the company's units that are being demolished around you, or some people who move in the community do not want to move furniture, leaving some furniture to sell at low prices. They also sold to the rack, the price is very cheap. If you are lucky, you will be sold very new appliances. However, it should be noted that after purchasing, you must find a professional installation personnel to install the machine. 3. See if the appearance is intact, whether there is a bump and deformation, whether the condenser wings are arranged neatly, whether the gap is uniform, and whether there is a loose. This will affect the heat dissipation and cooling effect. 4. Listening to whether there is a lot of noise when the machine is running. If the noise is large, it means that there is a problem with the balance of the fan. The body will also shake. 5. It is recommended to go to some personal exchanges or transfer websites. Buying from individuals is more secure than the second -hand electrical appliance market. And the price should not be expensive. Second -hand air -conditioning purchase method ① Check whether the appearance is intact. Check whether the case is cracked and deforms, whether the condenser wings are arranged neatly, and whether the gap is even. The gap will affect the cooling capacity, and the gap is too small to accumulate ash. It also depends on whether the fins and the copper tube are tightly applied, otherwise if it is loose, it will affect the heat exchange efficiency and reduce the effect of use. ② The window machine, cabinet machine, and split machine should be set up. The indoor and outdoor machines and even the copper pipe must be original. Generally speaking, the welded joints of the original accessories are smooth and uniform. ③ Listen to whether the sound of the indoor machine is light, stable, and uniform. If there is a regular or irregular noise, it means that there is a problem with the balance of the indoor fan. At this time, it will feel shaking with the case. ④ Look at the actual cooling effect. Refrigerate for 10 minutes, and the air outlet is a thermometer test. The temperature is generally 18 ~ 20 degrees. The lower the temperature, the better the cooling effect. Some shopping malls sell second -hand air conditioners. Both parties to buy and seller first talk about the price, send it to the user's home, install the test, and the user feels that he will pay before paying. This method is not as good as one.
