Now people pay more and more attention to health care, and air conditioning is an essential electrical appliance in the home. There are many home appliances that can use air conditioners on the market now. The most common air conditioners are variable frequency air conditioners and ordinary air conditioners. The air conditioner has been used for a long time, so we should pay attention to whether its automatic on-off function and automatic mode are normal. Let's talk about the principle of automatic switch of air conditioner. Air conditioning is automatically turned on and off through a special control mode-air conditioning compressor.

1, general air conditioning has two modes, cooling and heating, which can be selected according to your own needs.

Refrigeration needs to start the refrigerant compressor, thus reducing the indoor temperature. When heating, the refrigerant compressor needs to be turned off, and when the indoor temperature drops slowly, the refrigerant compressor needs to be turned on. Generally, the refrigeration time of refrigerants will be better within 1-3 hours. Of course, the price of air conditioners will be different.

2. If the inverter air conditioner is used, it will automatically shut down because it is the refrigerant compressor of inverter air conditioner.

After using the inverter air conditioner, it is necessary to turn on the compressor of the air conditioner regularly to operate normally. Frequency conversion air conditioning also needs a timing switch: when the time or temperature arrives, turn on the automatic mode and start the compressor; When the time is 2 and the temperature is 1, turn off the compressor. The inverter air conditioner will keep running until the temperature drops to the set temperature. When the compressor is turned off, the air conditioner will stop working for about 10 minutes. The inverter air conditioner can only be turned on for about 3 hours at most, and then it will stop running. The automatic mode on and off time of inverter air conditioner should be determined and started according to the ambient temperature, air conditioning state, outdoor air quality, refrigerant quality and user's usage habits.

3. In fact, the automatic air conditioner we usually use is an automatic on-off control mode in inverter air conditioner.

This control mode is that when the air conditioner works, the compressor controls the change caused by the indoor and outdoor temperature changes, so as to achieve the purpose of controlling the indoor temperature. Many people may think that this is a troublesome function and will not be used. In fact, it is the air conditioning startup function that we usually use. When the outdoor temperature is higher than the set temperature, it will automatically start this function.

4. If the air conditioner runs for too long, it will automatically shut down.

When this happens, it can start the cooling mode or heating mode, and then wait for the compressor to run for a long time and then automatically shut down. Many people don't know that air conditioning has this automatic mode when they use it at home. In fact, the air conditioner does not need to turn off the compressor to do this. When you turn off the air conditioner, the air conditioner compressor can still work normally. But if you turn off the air conditioner and turn it on again, you need to operate the air conditioner again. You can test how long it takes for the automatic switch of the air conditioner on the computer board at home. It is also very important that the air conditioner needs to clean the fuselage, filter screen and radiator frequently.
