What will stop outside the inverter air conditioner?

The outdoor unit of the air conditioner always stops suddenly, and the advantages of inverter air conditioning are reflected in this situation.

When the indoor temperature of the inverter air conditioner reaches the air conditioner, the outdoor unit stops when the air conditioner works in the refrigeration state. The internal machine will not stop, and the air supply will continue all the time. Circulate the air inside so you don't feel very hot until the air conditioner starts again.

When working in the heating state, the outdoor unit will be shut down, and the indoor unit will also be shut down. It is to prevent the internal unit from blowing cold air.

The operating speed of the inverter compressor can be adjusted appropriately according to the level of the room temperature, and when the room temperature is significantly different from the set temperature, the compressor will run at high speed to reduce the room temperature as soon as possible; When the room temperature is close to the set temperature, the speed of the compressor gradually decreases, so that the room temperature remains constant.

When we started the air conditioner, it started to stop and start frequently in about 3 minutes, and the air conditioner did not refrigerate. In this case, the cause is most likely a malfunction of the refrigeration system. At this time, observe the external unit, if it is found that the high-pressure pipe of the external unit is frosted, then it is likely that the filter is dirty and blocked.

Second, check whether the air conditioner lacks refrigerant or whether there is any leakage, and the serious shortage of refrigerant is also one of the reasons for the frequent shutdown of the external machine. Third, circuit system failure, it is recommended to check the fault on the main control board** (due to different brands of air conditioners** the meaning of the fault is also different).

The reason for repeated shutdown of the outdoor unit must be the protection lead, it is necessary to check the temperature detected by each sensor when the outdoor unit is shut down, the current, pressure and other parameters, and then see which of these parameters is abnormal, and further overhaul the abnormal parameters in order to eliminate the fault.

The inverter air conditioner will not stop working under normal use. However, the external machine may stop working if the following happens:

1.High temperature: When the outdoor temperature is too high, the outdoor unit of the inverter air conditioner may stop working due to overheating to protect the equipment.

2.Fault: If the external unit of the inverter air conditioner fails, such as circuit failure, compressor failure, etc., it will also cause the external unit to stop working.

3.Maintenance: It is very important to maintain the inverter air conditioner outside unit regularly, if it is not maintained for a long time, it may cause the outside unit to malfunction and stop working.

Therefore, in order to ensure the normal operation of the outdoor unit of the inverter air conditioner, it is recommended to carry out regular maintenance and pay attention to the influence of the temperature of the external ring socks.

The reason may be that the indoor temperature is similar to the set temperature of the air conditioner, and the outdoor compressor slows down the operation speed, which can be solved by waiting for the room temperature to rise; The reason may be that the protector output protection, which can be solved by turning off the air conditioner; The reason may be that the wired probe of the temperature control system is damaged, which can be solved by replacing the probe; The reason may be that the starting capacitor is damaged, and it can be solved by replacing the starting capacitor. 1. After the inverter air conditioner is running for a period of time, after the indoor temperature reaches the set temperature, the outdoor compressor will slow down the operation speed, and you can hear the sound of the outdoor fan rotating decreased, the speed decreased, and the refrigeration effect decreased. 2. If the outdoor unit suddenly stops running, and the fan does not rotate at all, it means that this is not a normal phenomenon, it may be that the outdoor compressor is running hot, and the temperature is too high to cause the protector to start, disconnect the circuit, and cause the compressor to stop running.

You need to turn off the air conditioner and wait for the temperature to return to normal before turning it on. 3. The temperature sensing head of the air conditioner is worn, resulting in a problem with the temperature sensing, and the temperature sensing head needs to be replaced.

The most likely cause is that the overload protection action is forced to shut down after the overload protection action, and the overload protection action is a system problem. For example, if the external unit is poorly installed, the heat dissipation is poor, and the high pressure is too high, the overload protection device will fall off, and the compressor will stop running, protecting the compressor from being burned. In addition, dirty evaporators and filters, dust accumulation, reduced airflow, and reduced heat exchange efficiency can cause liquid compression or antifreeze switches to fall off.

It is also possible that there is a circuit problem such as a temperature sensor failure, feedback of error messages, or a failure of the control board.

1. When the inverter air conditioner runs at low frequency, it will also produce a certain amount of cold and heat. If there is no energy loss in the room at this time, the inverter air conditioner will stop working;

2. When the voltage is insufficient or the voltage is unstable, the phenomenon of automatic stop of the air conditioner will occur at this time;

3. Due to the installation and maintenance of the air conditioner, garbage and air enter the pipeline, the air conditioning pipeline is blocked, which affects the circulation of refrigerant, the system can not be refueled normally, and the pressure is too large, resulting in the overheating protection of the compressor, resulting in the protective stop of the air conditioner;

4. When the ventilation of the outdoor unit of the air conditioner is poor or the condenser is too dirty, there is also a protective automatic stop-action phenomenon;

5. Air conditioning refrigerant leakage, air conditioning lack of fluorine, air-cultivated potato refrigeration capacity decreases, air conditioning is easy to overheat, automatic stop.
