With the continuous development of the society, people's living standards are constantly improving. Nowadays, people are buying air conditioners at home, but everyone knows that air conditioners are divided into frequency conversion and fixed frequency, but when purchasing, air conditioners buy inverters. The frequency is good, the next decoration home Xiaobian for everyone to introduce air conditioning to buy frequency or fixed frequency and how to buy air conditioning, I hope everyone in the purchase when reference. 1. Air conditioner to buy inverter or fixed frequency is good 1. For the sake of everyone, the working principle of the inverter air conditioner is to add a frequency converter on the basis of the fixed frequency, which is to automatically determine the required amount of heat (cold) according to the overall situation of the room, but when the indoor temperature reaches the set temperature However, the air conditioner host will judge to keep this temperature constant operation, and keep running without stopping the machine, which is equivalent to always working at low frequency to ensure that the indoor temperature is constant. 2. Next, the fixed-frequency air conditioner is operated according to the temperature set by the user. However, when the indoor temperature reaches the set temperature, it will stop working, but it will not automatically adjust according to the environment. 3. In the end, fixed frequency is not as common as frequency conversion. It has many advantages, such as low price, but the product variety is rich, the shortcoming is not intelligent enough; and the inverter air conditioner is smarter. There is also a much better comfort than the fixed frequency, so the price is relatively higher than the fixed frequency. The air conditioner works in the long term and may affect the life of the compressor. 4. In fact, the frequency conversion is not necessarily more energy-saving. According to the size of the region and the family environment, it can be saved in a reasonable way. But it can be said that if you use less air conditioning time per day, you can choose a fixed frequency, and the use of more than 10 hours may be more power-saving. 2. How to choose air conditioner 1. When we purchase air conditioners, we need cooling capacity: the output power of the air conditioner. It must be selected according to the size of the room. Only in this way can the effect be guaranteed, but the manufacturer's requirement is an average of 200 watts/square meter. For example, a room of 18 square meters requires a cooling capacity of 3,600 watts. You can buy a standard 3,500 watt machine on the market, referred to as the 35 machine, which is 1.5 machine. 2. There is also the choice of cooling capacity is the main performance choice of air conditioning, the cooling capacity is too large, the effect is good, then the cooling capacity is too small, but the purchase cost is low, but the effect is poor, power consumption. The cooling capacity of 2 or less is basically hanging up, and more than 2 are basically cabinet machines. 3. There is also the energy efficiency ratio: the energy efficiency of the air conditioner, look at the last number of the machine model. Energy efficiency ratio = cooling capacity / input power, the same amount of cooling machine. Nowadays, when buying air conditioners, I don’t know whether the frequency conversion is good or the frequency is good. The above article says that the air conditioner buys the frequency conversion or the fixed frequency is good and how to buy the air conditioner, Xiaobian said there. Not very clear, if you want to know more about the decoration information, please continue to pay attention to the decoration home network.
