Sihaiwang: the hot summer is coming. It's time to choose a suitable air conditioner. How to choose a suitable air conditioner? There are fixed frequency air conditioning and variable frequency air conditioning. There are only two kinds of air conditioning in the market. Is variable frequency air conditioning better than fixed frequency air conditioning? What is the difference between the two? What kind of air conditioner should we choose? Let's take a look at the following with these questions!
Good frequency or frequency conversion of air conditioner
Variable frequency air conditioning has its own advantages and disadvantages. Which air conditioning you need to buy should be considered according to your actual situation. You can decide which one you want to buy according to their advantages and disadvantages. Generally speaking, the fixed frequency air conditioning is more stable and the variable frequency air conditioning is more energy-saving.
Advantages and disadvantages of constant frequency air conditioning
Advantages: the constant frequency air conditioner is relatively stable in operation, and generally will not cause problems. Its technology is more sophisticated, suitable for a variety of environments, and the price is relatively cheap.
Disadvantages:
1. The compressor is often started frequently, which leads to large indoor temperature fluctuation and poor comfort experience.
2. The constant frequency air-conditioning compressor frequently starts and stops, because the power consumption is relatively large when the compressor starts, so the power consumption is large, and the power consumption is relatively high.
3. It takes a long time to turn on the heating and cooling system, and the constant frequency air conditioner takes a long time from turning on to increasing or decreasing to the set temperature, which is not conducive to people's enjoyment.
Air conditioning has fixed frequency air conditioning and variable frequency air conditioning. There are only two kinds of air conditioning in the market. So what kind of air conditioning should we choose?
Advantages and disadvantages of variable frequency air conditioning
Advantage:
1. The refrigeration is very fast and can reach the set temperature quickly.
2. Variable frequency air conditioning determines the power according to the number of needs, so the cooling and heating efficiency is high. It does not consume extra power, and saves power compared with fixed frequency.
3. Accurate room temperature control: the temperature control is accurate and stable, and the change range of room temperature is within + 0.5 ℃.
Disadvantages:
1. The price of variable-frequency air conditioning is more expensive. Compared with ordinary constant speed air conditioning, the price is 30% to 40% higher.
2. The control system and frequency conversion system of variable-frequency air conditioning are more complex, with higher requirements for components, and higher failure compared with constant frequency air conditioning.
How to choose air conditioner correctly
When selecting the number of air conditioning units, you can choose according to the area of the room, so that the purchased air conditioning power will not be too large or too small.
8-14m2, 1p air conditioner is recommended.
12-23 square meters, 1.5p air conditioner is recommended.
21-34 square meters, 2p air conditioner is recommended.
27-42m2, 2.5P air conditioner is recommended.
32-50 square meters, 3P air conditioner is recommended.
46-70 square meters, 5p air conditioner is recommended.
Next, let's look at the numbers 23 and 26 on the air conditioner model. This represents the cooling capacity of the air conditioner. The nominal cooling capacity of a horse is 2200w-2300w. 23 is a horse. It says 26 is 2600w. In addition, there are GW and LW marks. G stands for hanging machine and l stands for cabinet machine.
