In the hot weather, many citizens have begun to use air conditioners to remind everyone to be careful not to be fooled by unnecessary "air conditioner filling".

Ms. Liu said that a few days ago, there was a problem with an air conditioner at home. Because the warranty period expired, she found an air conditioner repairer online.

"After inspection, it was found that the air conditioner lacked fluoride and needed to be filled with liquid. It was said that each pressure was 4 ＄." Ms. Liu said that she didn't quite understand how to charge by pressure.

"4 sets of 1.5P each add 10 pressures, a total of 400＄ , and 3P cabinets add 12 pressures (the other side of the cabinet will charge 50 yuan for each pressure) for a total of 120 ＄." Ms. Liu said. 5 air conditioners added fluoride plus 550＄.

Event analysis

1. At present, the fixed-frequency air conditioner with the old refrigerant R22 as the refrigerant is the fixed-frequency air conditioner on the market that needs more maintenance. "The operating pressure is 0.49Mpa, and one unit can have at most 5 pressures. How can I charge for 10 units."

2. It is unreasonable to charge for the pressure value of the pressure gauge. There are many factors such as pressure and temperature, which can only indicate whether liquid is needed to be added, and cannot represent the amount of liquid added.

3. A 1.5P air conditioner requires 0.9 to 1.2 kilograms of refrigerant (the public can see the "refrigerant filling amount" mark on the outside of the air conditioner), and the maximum is 1 kilogram. The price of 1 kilogram of R22 refrigerant on the market is 30 yuan, plus maintenance fees, etc., generally the normal charge is 30 to 50 ＄.

4. The air conditioner "even after more than ten years of use, as long as it is installed in place and the seal is in good condition, there is no need to add liquid. Unless it is not in place when installed, it may be short of liquid and only use a small amount of liquid. Of course, there is also leakage However, the air conditioner will not operate normally, and it will be necessary to find the leakage point and repair it.

After analysis, it can be determined that Ms. Liu was fooled, and the maintenance cost of several hundred yuan was increased to more than two thousand. There are still a lot of tricks in air-conditioning repairs, and the editor behind will slowly analyze it with everyone.

This editor reminds everyone to pay attention:

To repair the air conditioner, find a qualified and regular repair company or repair shop, and pay attention to the ticket request. Regular home appliance repair merchants have the Municipal Bureau of Commerce.
