Don’t worry if the air conditioner is not cooling or self-protection function

The air conditioner at home didn't feel cold, so I quickly called an air conditioner repairer to add refrigerant. Yesterday, many citizens in Wuxi, Jiangsu Province reported that the weather has been very hot recently, but when the air conditioner was most needed at noon, they felt that the air conditioner was not cooling at all and had to ask someone to add refrigerant. In this regard, some maintenance masters said that in hot weather, if the air conditioner is not in the right position or the heat dissipation is not good, it will have a self-protection function and cause no cooling. There is no need to add freon. Using freon in excess of the standard will also damage the air conditioner.

　　 Master Li, who lives in Guangyi New Village, Wuxi, is a transporter. He will not go out at noon these two days, and has a nap with the air conditioner at home. "The air conditioner is on, and it feels like there is cold wind coming out, but it's not cold in the room for a long time, and I can't sleep at all." He suspected that the air conditioner had less Freon, and quickly called the master to add liquid. Recently, the maintenance master's phone call is quite difficult. Master Li said that he finally found someone, and his heart was at ease. But to his surprise, when the air-conditioning master came to add liquid, two other neighbors on the first floor also reported the same problem. I hope the master would help them add liquid together.

　　 However, a friend told him later that he should actually observe it again. Now many air conditioners have the problem of not cooling during the day. It is not because the air conditioner is broken or the refrigerant is gone. In the circle of friends, some people also sent WeChat to say that the air conditioner had no effect when it was turned on during the day. In fact, the external high temperature caused the abnormal heat dissipation of the compressor of the air conditioner, and the compressor produced overheat protection and could not be cooled normally. Some people suggest turning off the power and flushing the outside machine with water, it will cool down rapidly, and then start the refrigeration normally. Some netizens said that if the air conditioner is turned on at night and the cooling effect is good, don't call for repairs.

　　 In this regard, Master Sun from the Wuxi Convenience Service Center said that if the air conditioner is placed in a place that is not too open, the heat dissipation will not be good. For example, in some communities, the air conditioner's external unit is installed in a small grid, and the heat dissipation is more difficult, which will affect the operation of the air conditioner. There is another reason. If the outdoor unit is installed on the surface directly exposed to the sun, the hot outdoor unit will indeed protect itself under high temperatures and will no longer operate. As for what is said on the Internet, there is a certain reason why the compressor can be restarted by pouring water on the external machine. But people cannot always pour water to the outside machine. The water volatilizes quickly at high temperatures, and it is impossible to keep the machine running in this way. A more realistic method of operation is to add sun visors or awnings to the outside of the air conditioner. He said that if there is no refrigerant, it is impossible to have intermittent cooling problems. The refrigerant does not leak chronically, and generally leaks light all at once. He believes that if the current air conditioner does not appear to be moved, it is generally not necessary to add refrigerant within 10 years.
