It’s coming in the hot summer days. I believe that in the summer when the heat is hard to bear, most people will choose to turn on the air conditioner in their home to enter the summer mode. For families that have not yet purchased air conditioners or whose home air conditioners are no longer available, in the face of fixed-frequency and inverter air conditioners on the market today, it is difficult to choose which type of air conditioners. In recent years, many manufacturers' advertisements have strongly claimed that frequency conversion power saving, "advertising one night" and other advertising words let us subconsciously think that inverter air conditioners are more energy efficient than fixed frequency air conditioners.
So is this really the case? When it comes to this, we must first understand that air conditioning can be cooled, thanks to its core-compressor, we can compare the compressor to the heart of the air conditioner, just like the computer CPU, and the air conditioning cooling effect is also The power specifications of the compressor are closely related. Many merchants claim that AC inverter air conditioner can save 30%, DC inverter air conditioner can save 50%, inverter air conditioner is really so magical? Here is a rational analysis of the difference between fixed frequency and inverter air conditioner.
Principle of fixed frequency air conditioning
Conventional air conditioners are fixed-frequency air conditioners. At present, the technology is very mature. The working principle is that the compressor compresses the refrigerant into liquid refrigerant, and then sends it to the outdoor unit. After the heat is dissipated, it becomes a liquid refrigerant of normal temperature and high pressure, and the heat is exchanged. outdoor. That is to say, after we turn on the air conditioner, let the motor speed of the compressor operate unchanged, it is called fixed frequency. The fixed-frequency air conditioner is a unit that provides the processing air temperature change to the space area. Its function is mainly to adjust the parameters such as the temperature, humidity and cleanliness of the air in the room.
Inverter air conditioning principle
Inverter air conditioner is actually a special compressor for frequency conversion, which is used to increase the frequency conversion control system. The inverter air conditioner can adjust the temperature by changing the refrigerant circulation of the compressor to change the refrigerant circulation amount in the pipeline to change the cooling capacity. Unlike ordinary air conditioners, it can automatically provide the required amount of heat and temperature according to the situation, so as to reach a desired temperature value, and the empty host operates at a constant speed that can accurately maintain this temperature, thereby making the environment The temperature is relatively stable.
Comparison of the advantages and disadvantages of the two
For fixed-frequency air conditioners, first of all, in the case of price and the same specifications, the general inverter air conditioner is about one-third more expensive than the fixed-frequency air conditioner, and the fixed-frequency air conditioner is relatively stable, suitable for various environments and has a long life. Longer than inverter air conditioners. The disadvantage is that the compressor of the fixed-frequency air conditioner relies on its constant "opening and stopping" to adjust the indoor temperature. Due to the frequent opening and stopping of the fixed-frequency air-conditioning compressor, the indoor temperature fluctuates greatly, and it is easy to cause room temperature between opening and closing. It is hot and cold, and consumes more electricity.
The inverter air conditioner has fast cooling, more precise temperature control, low noise, and the human body feels more comfortable. It can also automatically select the heating, cooling and dehumidifying operation modes according to the ambient temperature, so that the living room can quickly reach the required temperature in a short time and Low temperature and low energy consumption with small temperature fluctuations, achieving fast, energy-saving and comfortable temperature control. The inverter air conditioner determines the power according to the required amount, so the efficiency is high. The main advantage of inverter air conditioner is that it can be stepless speed regulation, temperature control is more accurate, temperature difference is small, and human body comfort is better.
The disadvantage is that the control system and the frequency conversion system of the inverter air conditioner are more complicated, and the requirements for components are higher, and the failure rate is higher. In addition, the premise of frequency conversion air conditioning is that each time the power-on time is generally more than 5 hours, the advantages of power saving can be fully utilized. Because the inverter air conditioner just starts up, the compressor is in high-speed operation state, and the power consumption at this time is very large, so that the indoor temperature quickly reaches the set temperature. If the boot time is short, the inverter air conditioner will not be able to take advantage of its power saving, even if it costs more than the ordinary fixed speed air conditioner.
How should we choose?
Through the above comparison, we can easily find that the inverter air conditioner actually replaces the high-frequency operation of the fixed-frequency air conditioner for a short time with a small power operation for a long time. If the cooling demand is the same, the cooling capacity is the same. The power is also quite, and it is not arbitrarily said that the inverter air conditioner is more energy efficient. For the average family, the air conditioner is not always open, and the fixed-frequency air conditioner is more practical. For some special reasons, the long-term air conditioner needs to be used. The advantage of the inverter air conditioner is more obvious. You should do it according to your own needs. select.
to sum up:
At present, inverter air conditioners can't achieve obvious power saving, so when you buy air conditioners, you should not blindly listen to the "inverter air conditioners that save electricity". Of course, technology is improving. Due to the environmental protection and upgrading of refrigerants, inverter air conditioners are the trend. It is believed that with the development of technology, the advantages of inverter air conditioners will become more obvious, and their disadvantages will gradually improve. We also expect technology manufacturers to let us enjoy the comfortable working and living environment brought by air conditioning as soon as possible.
