Master these little knowledge, don’t be afraid of not understanding household central air-conditioning

Today we are here to spread a little knowledge for everyone on the most common situation, hoping to help you better use and understand the household central air conditioner.

Master these little knowledge, not afraid of not understanding household central air-conditioning

　　 Can cooling and heating be performed at the same time? Can't

　　Because household central air conditioners are usually one-on-one, many people have a whim when they use it. If I am too cold in this room, I will turn on the mechanism to heat it; if you are too hot in another room, turn it on to cool. Here we want to tell everyone that household central air conditioners do not have the function of cooling and heating at the same time, because all the air outlets lead to the same outdoor unit, and the outdoor unit can only perform a certain function.

　　Is the fan still running after shutting down, is it broken? Is not

　　 Many people reported that the air conditioner is turned off and the fan is still running. Is the air conditioner broken? Here we want to tell everyone, no. The fan is still running after the air conditioner is turned off because the residual heat or cold air is taken away in this way, so as to protect the heat exchanger of the air conditioner and prevent the air conditioner from scaling. In addition, the water pump of the air conditioner will continue to run for about two minutes before it stops automatically after shutting down. This is all normal, so don't worry.

　　 Is there always a pause when it starts running, is it normal? normal

　　 Generally speaking, since the air conditioner compressor has a self-protection mechanism, if the air conditioner is shut down and turned on again, the air conditioner itself will have a response time of 1-3 minutes, during which time the air conditioner will not operate.

　　 Is the fault code for the automatic start of the unit? Is not

Household central air conditioners are relatively difficult to maintain in later stages, so the protection mechanisms in all aspects are relatively complete. In order to prevent the water in the condensate pipe from freezing, generally speaking, the water pump of the air conditioner will automatically turn on when the water temperature is lower than 2. The unit will also automatically turn on to protect the air conditioner from freezing.

　　Is there any problem with the intermittent operation of the outdoor unit? No

　　The outdoor unit of the household central air conditioner generally uses frequency conversion technology. If the outdoor unit has a high temperature during operation, the outdoor unit will activate a protection mechanism to ensure that the outdoor unit is not affected. This is the reason for intermittent operation, so don't worry.
