Comparison of advantages, disadvantages and characteristics between variable frequency air conditioning and traditional air conditioning

Compared with traditional air conditioners, inverter air conditioners have the following five characteristics: small starting current, excellent low-temperature operation performance, stable temperature control, strong adaptability to power grid and rapid reaching of set temperature. In this paper, the advantages, disadvantages and characteristics of inverter air conditioner will be discussed in depth to help readers better understand this new type of air conditioner.

Low starting current

The starting current of inverter air conditioner is low, which avoids the impact of starting current on power grid and watt-hour meter and reduces the pulse interference to other household appliances in the room.

Excellent low-temperature operation performance

Frequency conversion air conditioner is obviously superior to traditional air conditioner in heating, which makes the warmth arrive faster.

Temperature control stability

Frequency conversion air conditioner avoids the problem of large temperature fluctuation of traditional air conditioner and makes the indoor temperature more stable and comfortable.

Strong adaptability of power grid

The inverter air conditioner can operate stably in a wide voltage range, even if the voltage is as low as 187V.

Quickly reach the set temperature

Frequency conversion air conditioner can quickly adjust the room temperature to the set range, and the comfort is instantly improved.

superiority

The combination of variable frequency power supply, variable frequency compressor, electronic expansion valve and microcomputer technology further improves the performance of variable frequency air conditioning. It makes the fluctuation of room temperature small, provides better comfort and is insensitive to the fluctuation of power supply voltage. In addition, after the compressor is started, it can keep running continuously, and the refrigeration capacity range is wide, which avoids the frequent start and stop of ordinary air conditioners and prolongs the service life of the compressor. At the same time, it also has the characteristics of high efficiency and energy saving.

disadvantaged

Although the performance of inverter air conditioner is excellent, its price is relatively high, which is about 1/3 ~ 1/4 higher than that of ordinary air conditioner. In addition, due to the complexity of control system and frequency conversion system, the requirements for components are high, and the failure rate may be high. Moreover, frequency conversion technology will produce certain harmonic pollution.
