An inverter is an electronic module that is built into an external unit of an air conditioner. The task of the inverter is to smoothly change the intensity of the compressor, reducing or increasing the power of the air conditioner.
The principle of operation of the inverter air conditioner
Conventional non-inverter air conditioners are controlled by a temperature sensor. It starts the compressor if the room temperature is higher than required. Once the air has cooled sufficiently, the temperature sensor stops the compressor. In this case, the fan continues to work in the internal module, so the user may not even notice a shutdown. But the air temperature is gradually rising. As soon as it increases by 1 or 2 degrees (depending on the model), the temperature sensor starts the compressor again. The last one turns on at full capacity of the air conditioner.
Cons of non-inverter technology:
- temperature differences in the room can reach 2 degrees, which in some cases is unacceptable;
- the compressor is constantly running at full power, even when you need to slightly cool the air;
- the air conditioner blows a stream with a temperature of +10 degrees, which creates uncomfortable conditions for finding people.
Inverter air conditioners are devoid of these shortcomings. The inverter controls the power of the air conditioner smoothly.
The compressor does not stop, it only reduces its speed to a minimum. Electronics converts alternating current into direct current, and then produces alternating current with the desired frequency. Thanks to this chain, the compressor operation intensity can be changed in a very wide range, affecting the electric power of the air conditioner.
The advantages of inverter control
How much power does the inverter affect? The level of cooling capacity changes, which is not possible with a clock control system.
Electric networks do not experience overloads, obligatory when starting the compressor.
The electric power of air conditioners varies depending on the need, due to this, energy is also saved (on average 30%, but special models up to 60%).
The noise level also depends on the power of the air conditioner. At inverters it is lower.
The resource of the air conditioner is saved, it wears out less, because each switching on and off reduces its “life”.
Smooth inverter control of the air conditioner power allows you to maintain the temperature in the room with an error of 0.5 degrees.
It makes it possible to work at lower external temperatures.
