First, understand the classification of air conditioners on the market: the difference between variable frequency air conditioners and fixed frequency air conditioners
1. Working principle: Fixed frequency air conditioners achieve cooling or heating effects through constant frequency operation. The speed of the fixed frequency air conditioner compressor is basically maintained at a constant value. So how to keep the room temperature at the set temperature? In order to get the set temperature value, the compressor can only be continuously turned on and off to make the temperature relatively constant, so sometimes the room temperature is cold and hot at times, which is caused by continuous startup and shutdown of compressor. Variable frequency air conditioners achieve changes in cooling and heat by adjusting the speed of the compressor to achieve more precise control. The core part of the air conditioner is the compressor, and its speed directly affects the use efficiency. By adjusting the frequency, the compressor speed can be adjusted to achieve stepless speed regulation. It can automatically adjust the temperature according to the set temperature. During the adjustment process, the compressor is always running, but the speed changes.
2. Power selection of inverter
The power requirement of the inverter depends on the power of the air conditioner. We can select the appropriate power of the inverter by querying the power of the air conditioner. Taking a 1-hp air conditioner as an example, it is recommended to choose an inverter with 3000W or higher. 90% of the power consumption of the air conditioner is used for its compressor. The compressors are inductive in nature, so it is recommended to choose an inverter that is 4 times or than the rated power of the air conditioner . Since the compressor of the fixed-frequency air conditioner is constantly turned on and off for cooling or heating, so it is recommended to choose an inverter with 5 times higher or more . Note that if the power of the inverter is insufficient, the inverter may overheat due to excessive load during operation, which will cause damage to the inverter.
3. Precautions for the use of the inverter
1). Note that the premise of a high-power inverter to run a high-power load is to have sufficient battery power support. Please make sure that the battery capacity can provide enough power for the inverter to run the air conditioner
2). The quality of the socket and plug should be good. In order to ensure the normal transmission of current, the contact between the socket and the plug should be bright and firm. If the contact is poor, it is easy to cause the line to heat up and affect the service life of the inverter.
3). The cable of the input end should be as short as possible. When buying an inverter, it usually comes with cables, and the quality of the cable is very important. If the cable is too long, it is easy to cause the line resistance to increase, causing the line to heat up.
4). Pay attention to the direction and ventilation during installation. The inverter will generate heat when working and requires good heat dissipation conditions, so pay attention to its placement direction and ventilation conditions.
In short, the inverter can drive the air conditioner. You only need to pay attention to the power of the inverter and the precautions and methods of use, and you can use the air conditioner when you are off-grid. The inverter has a wider range of applications in home life. I hope everyone can make better use of the inverter to bring more convenience to our lives.
