What Is Inverter Technology In Air Conditioners?

  Frequency conversion technology (inverter) in air conditioners is a way in which it controls cooling or heating by adjusting the speed of the compressor.

  Traditional air conditioners use non-inverter technology, while the compressor has only two states: "on" and "off". Once the indoor temperature reaches the set level, the compressor will shut down; when the temperature deviates from the set level, the compressor will restart.

  Inverter air conditioners adjust the compressor speed by changing its operating frequency so that it can dynamically adjust the output power according to the indoor temperature requirements, avoid frequent switching on and off, and thus control the room temperature more efficiently. And it can reduce the working intensity when the temperature is close to the set level, thus saving more energy.

  As a Wall mounted air conditioner factory, we can customize the air conditioner with or without an inverter function according to the customer's requirements.

Main Features of Inverter Technology

• Energy-Saving

  Inverter air conditioners quickly reach the target temperature at a higher power during the initial operation. When approaching the target temperature, the compressor speed is reduced to maintain stability, thereby avoiding energy waste caused by frequent start stops.

• Comfortable

  Since inverter air conditioners can maintain constant room temperature fluctuations (usually within ±1°C), users could experience smoother temperature changes and improved comfort.

• Quiet Operation

  The noise is lower when the compressor runs at low speed, and compared with traditional air conditioners, inverter air conditioners are quieter in operation.

• Fast Cooling

  Inverter air conditioners can quickly reach the set temperature by increasing the compressor speed, achieving a comfortable room temperature more quickly.

• Adaptability of Wide-voltage

  Inverter technology allows air conditioners to work stably even when voltage fluctuates greatly and is especially suitable for areas with unstable power supply.

Working Principles of Inverter Technology

  The core of frequency conversion technology is the inverter. The inverter converts the alternating current (AC) supplied by the power grid into direct current (DC) and then regenerates the alternating current by adjusting the output current frequency, thereby controlling the speed of the compressor. This dynamic adjustment mechanism enables the compressor to adjust the output power according to actual needs.

Pros and Cons

Advantage:

• Energy saving: Due to the built-in inverter of the inverter air conditioner, the operating speed of the compressor can be adjusted at any time, thereby achieving rational use of energy. As the infrequent opening of its compressor, it can maintain a stable working state, which can achieve an overall energy saving of over 30% for the air conditioner. At the same time, this has a significant effect on reducing noise and extending the service life of air conditioning.
• Low noise: Since the inverter air conditioner operates in a balanced manner, vibration is reduced, and the noise is also reduced accordingly.
• Accurate temperature control: It can control the cooling (heating) capacity of the air conditioner by changing the speed of the compressor. Its cooling (heating) capacity has a range of variation; for example, the cooling capacity of a 36GW frequency converter changes from 360-4000W and the heating capacity changes from 300-6800W. Therefore, indoor temperature control can be precise to ± 1 °C, making the human body feel very comfortable.
• Fast temperature adjustment: When there is a significant difference between the room temperature and the set temperature, the inverter air conditioner operates at maximum power as soon as it is turned on, causing the room temperature to quickly rise or fall to the set temperature, resulting in a significant cooling (heating) effect.
• Low voltage requirement: Inverter air conditioners have strong adaptability to voltage, and some inverter air conditioners can even start at 150-240V voltage.
• Low ambient temperature requirements: Inverter air conditioners have strong adaptability to environmental temperature, and some products can even start at an ambient temperature of -15℃.
• Maintain a constant room temperature: The inverter air conditioner uses a variable frequency compressor, which can automatically adjust the operating frequency of the compressor according to changes in the room's cooling (heating) load. After reaching the set temperature, the inverter air conditioner operates at a lower frequency to avoid discomfort caused by drastic changes in room temperature. When the load is low and the operating frequency is low, the compressor consumes less power and avoids frequent on-off, thus saving more electricity.

Disadvantage:

• Continuous operation: In Europe and the United States, most families are used to turning on the air conditioner all day long, or even never turning it off, because they want to achieve the effect of heating or cooling as soon as they enter the room. In some countries, most families will not turn on the air conditioner all the time, so the advantages of inverter air conditioners cannot be reflected because inverter air conditioners require themselves to run continuously to achieve the purpose of saving electricity.

• Core technology: The technology of inverter air conditioners is not yet perfect. Although merchants have been promoting the advantages of variable frequency, everyone knows that the more advanced the machine is, the more complex the parts are, and the higher the probability of failure. At the same time, the price will not be low when selling the machine.
• Electricity-saving costs: Let's calculate the cost of using air conditioners. For example, if the air conditioner is used for 4 months a year, 30 days a month, and an average of 8 hours a day, the cooling operation time is 960 hours. According to the average air conditioner power of 2000W, the total power consumption during the cooling period using a non-inverter air conditioner (EER = 2.6) is 1920 kWh. If an inverter air conditioner (EER = 3.3) is used, the total power consumption is 1510 kWh, and the power saving is about 410 kWh. Each unit saves only more than 270 Yuan in electricity bills each year. However, the price of an inverter air conditioner is more than 1,000 Yuan, higher than that of an ordinary air conditioner!

In addition, taking northern cities as an example, many areas have heating facilities in winter, and the air conditioning season is only about three months each year. Most of the time, the air conditioner is idle, and the advantages of inverter air conditioners are not obvious.

Summary

  Inverter technology is an important development direction of modern air conditioners. It can improve the user experience while saving energy and gradually become the mainstream configuration. For families or offices that need to use air conditioners for a long time, inverter air conditioners are undoubtedly a more economical and comfortable choice.
