Said inverter air conditioner power saving, inverter air conditioner really saving power? Why frequency conversion will save power, inverter air conditioner is much more expensive than ordinary air conditioner, cost-effective?
First of all, let's talk about why inverter air conditioners save power. What is the principle of power saving?
Inverter air conditioner power saving principle:
1. The principle of inverter air conditioner is that the air conditioner adopts a relatively advanced technology. The voltage at startup is small, and it can be started under low voltage and low temperature conditions. This may be difficult for the air conditioner to start due to unstable voltage or low indoor temperature in winter in some regions. The situation has a certain improvement effect. Due to the infinitely variable speed of the compressor, it can also adapt to a larger area of cooling and heating needs.
2. Simply put, the principle of inverter air conditioner is to add a frequency converter to the structure of the conventional air conditioner. The heart of the compressor air conditioner has its speed directly affecting the efficiency of the air conditioner. The inverter air conditioner inverter is used to control and adjust the compressor speed. The control system makes it always in the best speed state, thereby improving the energy efficiency ratio, saving 20%~30% than the conventional air conditioning.
Inverter air conditioner high-frequency operation more energy-efficient:
1. Inverter air conditioner operates at a high frequency except when it is turned on, and it operates at low frequency for most of the time, and its power consumption is much lower than that of fixed-frequency air conditioners. Compressors are large energy consumers in air conditioners, and their rated power accounts for the power of air conditioners. About 90%, the other 10% for fan motor and other electrical devices; and inverter air conditioner compressor efficiency higher than ordinary fixed-frequency air compressor.
2. The frequency of inverter air conditioners is much lower than the number of constant frequency air conditioner switches. The constant frequency air conditioners consume a lot of energy when they are turned on. AC inverter air conditioners require 30% power saving compared to fixed frequency air conditioners, and DC inverter air conditioners save 50%.
—Key power saving function:
1. Inverter air conditioner, with one-key power saving function. If you want to reduce the operating function of your home air conditioning, then you can press the power-saving operation button on the remote control, not only can reduce the operating power, but also in the period of peak power consumption Can reduce the risk of tripping.
2. Does inverter air conditioner really save power? Undoubtedly, inverter air conditioner has more energy-efficient features than traditional air conditioners, and the temperature control is more accurate, the noise is low, and the human body feels more comfortable. At present, the price of inverter air conditioner has been continuously adjusted, Gradually with the traditional fixed-frequency air-conditioning closer. In the future, full-inverter air conditioning instead of fixed-frequency air-conditioning will be the development trend of energy conservation and environmental protection.
What are the advantages of inverter air conditioners:
1. Refrigeration, heating, strong and rapid start, running at the highest power. Rapid cooling, heating. So that the indoor temperature suddenly reaches the set temperature. So whether it is cold morning, or hot day can be quickly Enjoy a comfortable room temperature.
2. High-efficiency and energy-saving Inverter air conditioners determine power according to the need, so the efficiency is high. In addition, since the compressor has almost no start/stop repeatedly, no extra power is consumed. Therefore, the electricity cost is only about 2/3 of the general air conditioner. Can be called an energy-saving model.
3. Comfortable and constant room temperature control Inverter air conditioner can control the speed of the compressor and freely change the power level to maintain a comfortable temperature.
However, inverter air conditioners also have some disadvantages:
1. The price is high: Although the advantages of variable frequency air conditioners are many, but its price will increase. After a period of popularity, I believe the inverter air conditioner prices will drop.
2. Cost recovery time is long: Inverter air conditioner is energy saving, because it will invest a lot of money before, so the cost recovery has become a problem. Inverter air conditioner energy saving effect will be determined according to different use environments and usage habits, so The cost recovery time will be longer. However, the current price gap between the variable frequency drive and the fixed frequency unit is no longer big. Coupled with the improvement of people's living standards, inverter air conditioning is basically the first choice for people.
Here are a few recommended ways to make the air conditioner more power efficient:
1. The normal winter air-conditioning temperature setting should be lower than the set temperature by 2°C to save about 20% of the electricity cost. Do not pursue high or low indoor temperatures during use. Although the human body was comfortable at that time, In the case of rapid temperature changes, it is prone to discomfort, etc. At the same time, if the temperature is set too high or too low, it will cause excessive power consumption.
2. The filter is an important part of the air conditioner. If it is not cleaned for a long time, it will not only have an odor in use, but it will be cleaned once or twice a year at least, and it will also affect the efficiency of cooling and heating when the air conditioner is used. Power consumption, and at least one year to clean one or two times.
3. The indoor environment is also an important factor affecting the air conditioning power consumption. If the airtight effect is good, the air conditioner will quickly adjust the temperature when it is turned on. If the airtightness is not good, the cold and hot air will continue to run off. The air conditioner will be in working condition. , Power consumption rises naturally.
4. According to the need to buy. According to their own use of area to choose air conditioning, if you buy a small number of air conditioners to a larger environment for cooling, then air conditioning will be in a state of constant load, and will increase product power consumption the amount.
