What is the difference between variable frequency air conditioner and fixed frequency air conditione

How about variable frequency air conditioner and fixed frequency air conditioner? In recent years, frequency conversion products have gradually occupied the market and become the first choice for many consumers. However, many people do not know what is good about frequency conversion air conditioning? Which is better, variable frequency air conditioner or fixed frequency air conditioner? Now let's learn about it

Which is better, variable frequency air conditioner or fixed frequency air conditioner?

Frequency conversion air conditioner selects frequency conversion special compressor and adds frequency conversion control system on the basis of ordinary air conditioner. Its basic structure and refrigeration principle are exactly the same as that of ordinary air conditioner. The host of variable frequency air conditioner is automatically stepless, which can automatically provide the required cooling (heating) capacity according to the room conditions; When the indoor temperature reaches the expected value, the air withering host runs at a constant speed that can accurately maintain this temperature to achieve 'non-stop operation', so as to ensure the stability of the ambient temperature.

What are the advantages of variable frequency air conditioning?

1. Energy saving

Because the frequency conversion air conditioner can adjust the running speed of the heart compressor of the air conditioner at any time through the built-in frequency converter, so as to make rational use of energy; Because its compressor will not be opened frequently, it will keep the compressor in a stable working state, which can save energy by more than 30% as a whole. At the same time, it plays an obvious role in reducing noise and prolonging the service life of air conditioner.

2. High temperature control precision

It can control the cooling (heat) capacity of the air conditioner by changing the speed of the compressor. The refrigerating (heating) capacity has a variation range. For example, the refrigerating capacity of 36gw frequency conversion is 360-400w and the heating capacity is 300-6800w. Therefore, the indoor temperature control can be accurate to & plusmn; 1 ℃, making the human body feel very comfortable.

3. Low noise

The variable frequency air conditioner operates in balance, reduces vibration and noise.

4. Fast temperature regulation

When there is a large difference between room temperature and set temperature, the variable frequency air conditioner will work at the maximum power as soon as it is started, so that the room temperature will rise or fall to the set temperature rapidly, and the refrigeration (heat) effect is obvious.

It can intelligently identify the room size and distribute the cold (heat) quantity, so that rooms of different sizes maintain the same temperature.

The variable frequency air conditioner adopts the variable frequency compressor, which can automatically adjust the operating frequency of the compressor according to the change of room cooling (heating) load. After reaching the set temperature, the variable frequency air conditioner operates at a lower frequency to avoid discomfort caused by drastic changes in room temperature. When the load is small and the operation frequency is low, the power consumed by the compressor is small, and frequent startup and shutdown are avoided, so as to save power.

5. Low voltage requirements

Variable frequency air conditioners have strong adaptability to voltage. Some variable frequency air conditioners can even be started at 150-240v voltage.

6. Low ambient temperature requirements

Variable frequency air conditioner has strong adaptability to ambient temperature, and can even be started at an ambient temperature of 15t.

Analysis of disadvantages of variable frequency air conditioner:

1. Limited by the manufacturing cost of variable frequency air conditioner, the price disadvantage has existed since the introduction of variable frequency products. However, in the development process of variable frequency in recent years, the price gap is gradually narrowing, but there is still not much choice for the price of fixed frequency air conditioner.

2. At present, there are many kinds of variable frequency air conditioners in the market, which still has no advantage over fixed frequency air conditioners.
