What is the difference between inverter air conditioner and fixed frequency air conditioner
1. What is inverter air conditioner? Frequency conversion means that the frequency is variable and adjustable. Compared with traditional air conditioners, the generation of frequency conversion air conditioners is due to the rapid development of power electronics technology and technology. Frequency conversion is to change the 50Hz of commercial power to 30~130Hz. Frequency. The core part of the air conditioner is the compressor. Its speed directly affects the efficiency of the value. By adjusting the frequency, the compressor speed can be adjusted to achieve stepless speed regulation. It can automatically adjust the temperature according to the set temperature. During the adjustment process, the compressor The machine is always running, but the speed has changed, which can be said to be a smarter air conditioner. Frequency conversion is divided into AC and DC frequency conversion.
Second, the advantages and disadvantages of inverter air conditioner 1) Advantages of inverter air conditioner
①Energy saving: due to the function of the internal frequency converter, the compressor will not start frequently, and the starting current is also very small;
②Intelligently adjust the room temperature: the compressor intelligently changes the speed according to the temperature change, keeping the room temperature at a constant value and making the human body feel more comfortable;
③Low noise: lower noise than fixed frequency air conditioner, this is due to the imbalance of the compressor, etc., and compared with the frequent start noise of fixed frequency air conditioner compressor;
④Wide voltage operation: Since the fixed frequency air conditioner needs a starting capacitor to start, the voltage must not be too low, but the frequency conversion can achieve soft start, and the voltage input requirements are not very strict;
⑤Fast cooling (heat) speed: Because the inverter air conditioner adopts special electronic expansion throttling and other technologies, and at the same time, the temperature difference is large, it runs at high power, causing the temperature to rise or fall rapidly;
2) Disadvantages of inverter air conditioner
① Difficulties in maintenance: Since inverter air conditioners have more frequency converters than ordinary air conditioners, the circuit and structure are more complicated, the probability of problems is greater, and maintenance becomes more difficult;
②High price: due to the complexity and advantages of inverter air conditioners, the price is about 1,000 more than ordinary air conditioners;
③ There are other shortcomings, such as the need to keep running to reflect its energy-saving features. 3. What is a fixed frequency air conditioner? Fixed frequency, that is to say the frequency is fixed, our domestic household appliances are 220V/50Hz, so the frequency of fixed frequency air conditioner operation is 50Hz, so the fixed frequency air conditioner compressor speed is basically maintained at a constant value, so how to maintain room temperature What about the set temperature? To get the set temperature value, the compressor only keeps on and off, so that the temperature is relatively constant, but sometimes we will feel that the room temperature is suddenly cold and hot, which is caused by continuous startup and shutdown.
Fourth, the advantages and disadvantages of fixed frequency air conditioning 1) Advantages of fixed frequency air conditioner
① Maintenance is relatively easy: the fixed frequency air conditioner lacks inverters and other components, especially the internal structure is more complicated when the DC frequency conversion is used. Therefore, once the fixed frequency air conditioner is damaged, it is much easier to repair than the inverter air conditioner;
②Cheap price: Due to the early development of fixed frequency, the current inverter air conditioner is more expensive than fixed frequency by thousands of pieces;
2) Disadvantages of fixed frequency air conditioning
①Noisy: The constant frequency air conditioner is constantly turned on and off due to its own speed at the same time, the speed is also very high, and the noise is relatively large;
②The temperature difference is too large: because the temperature adjustment is to keep the room temperature constant by continuously starting and disconnecting the compressor, this does not have the frequency conversion intelligence. The room temperature and the set value fluctuate too much, sometimes it will cause people to suddenly heat and cold feel.
5. How to choose between frequency conversion and fixed frequency? Nowadays, air conditioners have entered thousands of households, and there are more choices for air conditioners, especially inverter air conditioners developed later, and major businesses are also under the slogan "Economy and Energy Saving". As consumers, they sometimes basically follow Popular, so how to choose the air conditioner that suits you?
1. According to the indoor area
The indoor area directly determines the number of air conditioners you choose. For example, if the area is not greater than 15 square meters, you can choose 1P air conditioner. For details, please refer to the data given by the merchants. Try to avoid the area being too large and the number of air conditioners. Small situation, because if this is the case, the air conditioner will always be in high-speed operation, which is not conducive to power saving and service life;
2. Choose frequency conversion or fixed frequency
In fact, this should be decided according to itself. First of all, the frequency conversion can save energy in many cases, but it is only for continuous work. If it is only opened for a few hours for a period of time, then it can not reflect its superiority. It’s better to come out with a fixed frequency. If you are looking for comfort, frequency conversion is the best choice. If you are a migrant worker or are not very frequent when using air conditioners and can receive the noise caused by frequent compressor startup, etc. Impact, fixed frequency can be considered at this time, because the price is relatively cheap, and easy maintenance.
3. Others: For example, the air conditioner is divided into wall-mounted type, vertical cabinet type and mobile type. According to your own use conditions, the general wall-mounted type is suitable for family use, while the vertical cabinet type generally appears in shopping malls and supermarkets; cooling and heating types, there are cooling and simultaneous Cooling and heating; there are other additional features of the product, such as remote control
