Life must be carefully calculated to buy what air-conditioning economy and power?

Whether in winter or summer, air conditioning often plays a very important role in improving our lives. However, the long-term use of air conditioners will definitely face the problem of excessive electricity bills. What air conditioners are the most economical and energy-saving? We look at these two aspects.
To understand whether the air conditioner consumes electricity during use, the most intuitive way is to understand the energy efficiency ratio of the air conditioner. The energy efficiency ratio of air conditioner refers to the ratio of air conditioning refrigeration capacity to operating power, and the consumption of smaller power to produce larger air conditioner can make the energy efficiency ratio higher. At the same time, air conditioning still has the concept of heating energy efficiency, but if you live in the warm south, you don't really need to care about this parameter. The blue and white background color logo attached to the air conditioner is the reference for the energy efficiency rating of the air conditioner. According to the energy efficiency ratio of air conditioners, the energy efficiency grades are divided into multiple grades, of which the first grade products have the best energy saving effect and the lowest energy consumption. The second-level energy-efficient air conditioner is second, and the third-level energy-efficient product is the average standard in the current air-conditioning market in China, and so on. At present, the price of low-energy products is slightly higher, and consumers can measure the price and power consumption of products to purchase.
In addition, the operation mode of the air conditioner also determines whether the power consumption is high. At present, air conditioning products are divided into fixed frequency and frequency conversion. The difference between them is whether the compressor is equipped with an inverter. The inverter is installed with an inverter air conditioner, which can effectively adjust the working speed of the compressor. For fixed-frequency air conditioners, when the indoor temperature reaches the set temperature, the compressor will stop working. When the room temperature rises, the compressor will turn on and continue to cool down. Such multiple shutdowns will result in a large amount of power consumption. The inverter air conditioner starts to run at a lower rate when the temperature is close to the set temperature, and maintains the indoor temperature. Considering that the price of inverter air conditioner is relatively high, from the point of view of usage habits, if it is used for a long time, inverter air conditioner is more energy-efficient, on the contrary, it is the most affordable fixed-frequency air conditioner.
