Why do air conditioning merchants always say: laymen buy frequency converters, while laymen buy fixed frequencies? There is a significant difference between the two

When purchasing air conditioning, one often hears the following sentence:Non professionals buy frequency converters, while professionals buy fixed frequencies

So, what are variable frequency air conditioners and fixed frequency air conditioners, and what are the differences between them?

This article will provide a detailed explanation to help everyone better choose the right air conditioner for themselves.

1.1 Constant frequency air conditioning

Fixed frequency air conditioning, also known as constant speed air conditioning, has a compressor with only one fixed speed, which means it has only one cooling or heating effect.

This type of air conditioner needs to be continuously started and stopped when in use, as its operating speed cannot be adjusted. Due to its low cooling efficiency, its power consumption will also be higher.

1.2 Variable frequency air conditioning

The compressor of variable frequency air conditioning can adjust its speed according to changes in indoor temperature to achieve higher efficiency and lower energy consumption.

This type of air conditioner can adjust the cooling/heating effect under different ambient temperatures, ensuring a constant indoor temperature. Moreover, due to its ability to adjust the speed as needed, it is more silent than a fixed frequency air conditioner.

2.1 Energy consumption

Variable frequency air conditioning can automatically adjust the compressor speed during refrigeration/heating, thereby achieving higher efficiency and lower energy consumption.

According to statistics, under the same refrigeration/heating effect,Variable frequency air conditioning can save more than 30% of electricity compared to fixed frequency air conditioning.

Moreover, due to the more precise temperature regulation of variable frequency air conditioning, it can also make users more comfortable.

2.2 Noise

Due to the fact that the compressor of the variable frequency air conditioner can automatically adjust the speed, its noise will also be lower.However, fixed frequency air conditioners require frequent starting and stopping during refrigeration/heating, resulting in relatively high noise levels.

2.3 Price

The price of variable frequency air conditioning is higher than that of fixed frequency air conditioning, but in long-term use, variable frequency air conditioning has lower energy consumption, so it also has more advantages in energy conservation.

2.4 Maintenance

Variable frequency air conditioning may have some difficulties in maintenance because its internal structure is more complex. The internal structure of fixed frequency air conditioning is relatively simple, so it will be more convenient in terms of maintenance.

Advantages of variable frequency air conditioning:

a. Energy conservation and environmental protectionVariable frequency air conditioning can achieve more precise energy consumption control by automatically adjusting the cooling/heating power, thereby achieving energy-saving and environmental protection effects.

b. ComfortVariable frequency air conditioning can automatically adjust according to indoor temperature, achieving a more comfortable user experience.

c. StabilityDue to the complex circuit system and controller used in variable frequency air conditioning, it can better adapt to different usage scenarios and environments, resulting in high stability.

Disadvantages of variable frequency air conditioning:

a. High priceDue to the complex technology of variable frequency air conditioning, the price is relatively higher compared to fixed frequency air conditioning.

b. High maintenance costsDue to the complexity of the circuit system and controller of variable frequency air conditioning, the maintenance cost is also relatively high.

Advantages of fixed frequency air conditioning:

a. Affordable priceThe technology of fixed frequency air conditioning is relatively simple, so the price is relatively low.

b. Low maintenance costsDue to the simple structure of fixed frequency air conditioning, the maintenance cost is also relatively low.

Disadvantages of fixed frequency air conditioning:

a. Low energy efficiency:The energy efficiency of fixed frequency air conditioning is relatively low, which may waste unnecessary electrical energy.

b. ComfortDue to the inability of fixed frequency air conditioning to automatically adjust the cooling/heating power, overcooling or overheating may occur, thereby reducing comfort.

c. StabilityDue to the relatively simple circuit system and controller of fixed frequency air conditioning, its stability is relatively low.

4.1 Usage occasions

For household use, if you need to use air conditioning in areas with relatively stable temperatures or only in summer, fixed frequency air conditioning is a good choice.

Because in this situation, the advantage of variable frequency air conditioning is not very obvious, while the price of fixed frequency air conditioning is relatively more affordable. But if you need to use air conditioning for a long time or live in areas with significant temperature changes, choosing variable frequency air conditioning will be more cost-effective.

4.2 Area size

The usage area of air conditioning is also an important factor in selecting air conditioning. If your room area is relatively small, then fixed frequency air conditioning is sufficient to meet your needs, as its cooling/heating effect is already sufficient.

If your room area is relatively large, it is recommended to choose variable frequency air conditioning because it can better control the indoor temperature and make you more comfortable.

4.3 Economic strength

When choosing air conditioning, economic strength is also a factor to consider.

Although the price of variable frequency air conditioning is relatively high, its energy consumption is lower in long-term use, so it also has more advantages in energy conservation. So, if your economic strength allows, you can consider choosing variable frequency air conditioning.

Summary:

As one of the essential electrical appliances in our daily life, choosing a suitable air conditioner is very important. This article provides a detailed introduction to the differences between variable frequency air conditioning and fixed frequency air conditioning, including energy consumption, noise, price, and maintenance.

When choosing an air conditioner, it is necessary to consider factors such as usage, room area, and economic strength. Choosing a suitable air conditioner can better enjoy the comfort and convenience it brings.
