Is it better to choose inverter or fixed frequency for air conditioning in the living room?

Buying an air conditioner is good for inverter.

1.High temperature control accuracy.

It can control the amount of cooling (heat) of the air conditioner by changing the speed of the compressor. There is a change in the cooling (heat) capacity, such as the cooling capacity of 36GW inverter changes to 360 400W, and the heating change is 300 6800W, so the indoor temperature control can be accurate to 1, so that the human body feels very comfortable.

2.The temperature is adjusted quickly.

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

If you use it in the living room, it's better to use the frequency conversion.

Because the living can be always on, if the frequency is fixed, the temperature will stop when the temperature rises, and the air conditioner will be turned on again when the temperature drops or rises, and the indoor temperature fluctuates greatly, which is not good for the body. The air conditioner in the bedroom is generally turned on for a long time, which is indeed more energy-efficient than the fixed frequency machine. If you only have a short meeting, the power consumption is not much different from that of a fixed frequency machine.

IntroductionThe biggest advantage of inverter air conditioning is not in power saving, but in the comfort brought by constant temperature, and the wind is relatively soft, so the bedroom treasure introduced by the industry is all inverter, and the high requirements for temperature due to resistance and metabolism when people are asleep are well known. The living room air conditioner has a large cooling capacity, which is not too sensitive to temperature changes, and if you choose two or three horsepower cabinets or hang inverter air conditioners, the cost is also quite high.

Is it better to buy inverter or fixed frequency for air conditioners?

Buy 50 ordinary heating and cooling or single cooling machine is old, and you don't need to convert the frequency, and the frequency conversion machine is more expensive.

It depends on the frequency of use of air conditioners. If you use it frequently and turn on for a long time each time, you can consider buying an inverter air conditioner. The inverter air conditioner has a fast refrigeration and heating speed, a small indoor temperature difference, and good comfort, but the inverter air conditioner can only give full play to its power-saving characteristics when it is turned on for a long time each time, otherwise the power consumption is similar to that of the ordinary fixed-speed air conditioner, or even more.

Therefore, if your air conditioner is turned on for a short time each time, it is enough to buy a fixed-speed air conditioner with a first-level or second-level energy efficiency ratio. Not only is the price low, but it is also very energy-efficient, and the failure rate is also low, and the maintenance cost is also less. 20 square living room, poor sealing and thermal insulation conditions, if only summer refrigeration use, buy a large horse of air conditioning on it, if you need to heat in winter, it is best to buy a small two horses of air conditioning, so that the effect will be better.

First of all, the compressor stops working after the traditional fixed-speed air conditioner reaches a pre-set temperature (the error is plus or minus two degrees). When there is a large difference between the room temperature and the set temperature, the compressor is restarted. In this way, the compressor is actually in a state of on/off during continuous operation.

As we all know, electrical appliances consume the most electricity when they are started and turned off, and after reaching the preset temperature (the error can be controlled within degrees), the inverter air conditioner will also run uninterrupted at a low speed, and sense the slight changes in indoor heat, adjust the frequency and speed by itself, and maintain a constant temperature. Therefore, in comparison, inverter air conditioners save a lot of electricity.

Second, the traditional fixed-speed air conditioner runs at a constant full power every time the temperature is changed, and when it only needs to be fine-tuned, it wastes a lot of power; The inverter air conditioner changes the operating power according to the actual needs, which naturally saves a lot of electricity costs.

Third, the inverter air conditioner is very efficient at start-up, which is the so-called "efficient start-up". At the beginning of start-up, the inverter air conditioner with a rated power of positive power can even reach the output capacity of horsepower, while the output power of traditional fixed-speed air conditioner is always very constant. In contrast, the start-up of inverter air conditioners is efficient and fast, and it also saves a lot of energy.

Fourth, it is worth mentioning that the energy-saving effect of DC inverter air conditioner is one step further on the basis of AC inverter air conditioner. This is mainly due to the abandonment of the original "AC voltage, DC voltage, AC voltage, variable speed AC motor" cycle working mode of ordinary inverter air conditioning compressor, and the use of advanced "AC voltage, DC voltage, variable speed mode digital motor" control technology, reducing the number of current transformations in work, so that the power conversion efficiency is greatly improved. The efficiency of DC inverter compressor is about 10%-30% higher than that of AC inverter compressor.

So how much electricity can an inverter air conditioner save compared to a traditional fixed-speed air conditioner? This figure depends on the specific model and the installation environment of the air conditioner, and the figure given by experts according to the average level is that AC inverter air conditioner can save about 25%-30% of electricity, while DC inverter air conditioner can reach more than 30%-40%, or even close to 50%.

At present, among the air conditioning products of the same grade and the same power on the market, the price of inverter air conditioner is about 1,000 yuan higher than that of traditional fixed-speed air conditioner. Both experts said that based on the safe service life of air conditioning products of 10 years, the electricity cost saved by purchasing inverter air conditioners definitely exceeds the purchase cost of 1,000 yuan more. Therefore, it is worthwhile to choose an inverter air conditioner.

If the air conditioner usage rate is not high, and it is not to be installed in the bedroom, then it is good to choose a fixed frequency one! The power-saving advantage of inverter air conditioner should be reflected from long-term operation, if the usage rate is not particularly high, then there is little difference between fixed frequency and inverter in terms of electricity consumption.

On the other hand, because the inverter air conditioner does not start frequently, the noise during operation will be relatively smaller, but the compressor is installed outdoors in the outdoor unit, and the impact on the indoor unit depends on the specific installation location of the outdoor unit, and the impact on the indoor unit is generally not too great!

The third aspect is the price, the fixed frequency price has a more obvious relative advantage than the price of the frequency conversion; So if you want to choose, you can at least refer to the three aspects I said above, and decide according to the actual usage!

It is recommended to fix the frequency, the frequency conversion does not save electricity, followed by the fixed frequency is more than the frequency conversion power-saving air conditioner, followed by the technology is mature and the price is low.

The living room is an open space, and the temperature is difficult to control for a long time, so choose the frequency conversion to save electricity.

In this case, you can buy an ordinary fixed-speed air conditioner, and the inverter air conditioner can only give full play to its power-saving characteristics when it is turned on for a long time.

For a 40-square-meter living room, you should buy a three-horse air conditioner. For a 15-square-meter bedroom, you should buy a horse air conditioner with a cooling capacity of 3200W, commonly known as a small horse air conditioner. The bedrooms are suitable for installing inverter air conditioners.

It mainly depends on whether you use it often, if you often use air conditioning, it is recommended to use frequency conversion, if you don't use it for a long time, use fixed frequency.

The frequency conversion is good, the energy consumption is low, and the noise is also low.
