Sihaiwang: in the sultry summer, a cool air conditioner has become a necessity in life. But when we choose air conditioner, how to choose variable frequency air conditioner and constant frequency air conditioner? What is the difference between variable frequency air conditioning and constant frequency air conditioning? What are the advantages of variable frequency air conditioning? Next to understand the principle of variable frequency air conditioning, you can have a look at what you are interested in.
Principle of variable frequency air conditioning
The working principle of variable frequency air conditioning is the principle of refrigeration and heating. Gas refrigerant is needed for refrigeration and heating, such as Freon, non fluorine environmental protection refrigerant, etc. when these refrigerants change from gas to liquid refrigerant, they need to exhaust heat, when liquid refrigerant changes into gas refrigerant, they need to absorb heat, and then transfer heat by means of transporting refrigerant to achieve the effect of refrigeration and heating. Of course, frequency conversion and fixed frequency are different. It uses a frequency converter equipment, which can freely control the operating frequency of the compressor, thus realizing the advantages of power saving and even temperature change.
Classification of variable frequency air conditioning
Variable frequency air conditioning is mainly divided into DC variable frequency air conditioning and AC variable frequency air conditioning. Its working principle is actually different in the way and frequency of compressor conversion current, and the compressor used is also different, so DC frequency conversion and AC frequency conversion are also different in the actual power consumption. DC frequency conversion is more power-saving. Generally, AC frequency conversion air conditioning saves about 30% of the power compared with constant frequency air conditioning, while DC frequency conversion air conditioning can save 50% of the power.
What's the difference between variable frequency air conditioning and constant frequency air conditioning? Let's understand the principle of variable frequency air conditioning. You can have a look at what you are interested in.
Difference between variable frequency air conditioning and constant frequency air conditioning
1. Different compressors
The compressor operating frequency of constant frequency air conditioning is not variable, all of which are 50Hz, while the operating frequency of variable frequency air conditioning compressor can be changed, ranging from 25Hz to 120Hz.
2. Different controllers
The controller of variable frequency air conditioner is more complex than that of constant frequency air conditioner.
3. Different output capabilities
In a working condition, the constant frequency air conditioner has only one ability to output, and the output ability of the variable frequency air conditioner can be adjusted at any time according to the change of the working condition.
4. Different comfort
The comfort of the variable frequency air conditioner is much better than that of the constant frequency air conditioner. It can quickly cool or heat, with small temperature fluctuation and high temperature experience comfort.
5. Different energy conservation
From a year's work, the variable frequency air conditioning will save more than 30% of the power than the ordinary air conditioning. However, it should be noted that frequent switching frequency air conditioning can not save electricity.
6. Different environmental adaptability
The variable frequency air conditioner can also make heat at the lowest temperature of - 15 ℃, while the common constant frequency air conditioner has almost no heating effect at - 5 ℃, so it can be said that the variable frequency air conditioner is more suitable for places with low temperature.
