Is it necessary to install central air conditioning in your residential area?

Central air conditioning is now entering the homes of more and more residents in an orderly manner, and the proportion is increasing. Various brands have also launched various competitions. However, in the process of grabbing the market, their misleading advertisements have made the people more and more frustrated, and they don't know whether to pretend.
In fact, central air conditioning does not save money. Many brands are promoting energy saving of central air conditioning, which means saving electricity, and saving electricity means saving money. However, about the energy saving of central air conditioning, the seller often talks about its rated cooling power and heating power. What's more, they will take the rated power according to the proportion of energy consumption to get the actual energy consumption. Yes, several so-called leaders in my former company cheated customers in this way, and even taught new people several times in the company's internal training meeting. To tell you the truth, I graduated from electrical engineering. I really want to interrupt them when they say this. Back to the above topic, if we only look at the rated power, we can't draw the conclusion that they must save electricity.

Because the starting ratio of air conditioner and light bulb is different, the rated power does not reflect the real power consumption. Because this is related to the actual work of air conditioning, indoor and outdoor temperature difference, air-to-air frequency conversion series, and temperature sensitivity that triggers air conditioning work.
However, according to the feedback from many of our users, the energy consumption of opening one indoor unit is not much different from that of opening two indoor units, but the energy consumption of opening only one indoor unit is very high, even exceeding that of a single air conditioner with the same number. This may not directly indicate that the central air conditioner consumes electricity, but it does indicate that the central air conditioner does not necessarily save electricity. Moreover, even if we can save electricity, we use the biggest assumption to calculate, assuming that the air conditioner is turned on for four months a year, with an average of 8 hours a day, which is 960 hours. If you can save 30% electricity per hour, you can save about 1 hour 960 kWh a year, and the electricity fee is 500 yuan.

Well, if you buy an imported brand of central air conditioning system, then you spend at least 1.5 million yuan more than a single machine. Then 30 years later, the extra money you spent at that time was saved, and the life of central air conditioning is only 20 years. What's more, it is not certain whether we can achieve four months of air conditioning season every year or eight hours of use every day. Therefore, we must treat power saving rationally.
