1. Whether the central air conditioner consumes power depends on the energy consumption ratio first
With major manufacturers investing heavily in research and development of central air conditioners, the energy efficiency ratio of central air conditioners has reached a level that exceeds that of ordinary air conditioners such as cabinet and split air conditioners. The energy efficiency ratio of general household split air conditioners is about 2.3 to 2.8, while that of central air conditioners can reach more than 3.0. This means that at the same temperature, the power consumption of household central air conditioners is lower than that of ordinary cabinet and split air conditioners.
In addition, the central air conditioner can also be used with a wall-hung boiler, and the energy efficiency ratio can be increased to more than 5 with the help of ground source heat pump technology. Therefore, from this point of view, the power consumption of household central air conditioners is not large.
2. Consuming more power than traditional air conditioners is a misunderstanding
From a functional standpoint, a household central air conditioner is equivalent to several wall-mounted and cabinet-type machines, and its power consumption is less than the sum of the power consumption of one air conditioner installed in each room. However, the effect is better than that of installing several units, and the operating cost is much lower than that of split air conditioners. The central air-conditioning refrigeration station can directly control the start-stop time and cooling capacity of the refrigerator, and can be adjusted according to climate change to save operating electricity costs.
From the above analysis, the power consumption of household central air conditioners is not more than that of wall-mounted and cabinet-type splits, and the electricity bill is much lower than that of heating. Whether it is in terms of performance, appearance or overall use effect, central air conditioners are superior to traditional air conditioners.
3. How can the air conditioner be used to save electricity?
In fact, power consumption is related to various factors such as the number of people in the room and the tightness of the room. Generally speaking, the air-conditioned room must be well sealed, and the windows should be closed tightly when in use to keep the air-conditioning from losing; it is best not to enter and exit the room too frequently; if the light in the room is too strong, the curtains can be drawn during the day to block part of the heat. Some people are afraid that using the air conditioner for a long time will consume electricity, and think that it will save electricity after turning it on and off for a while. On the contrary, when the air conditioner is started at high frequency, the current is large instantly, and frequent switching consumes the most power and loses the compressor. Therefore, do not
4. How to use central air conditioning correctly?
Experts remind that the correct way to use it is: when setting the room temperature, do not set the temperature difference with the outside too much, such as 30 ° C outdoors, 25 ° C indoors is enough, after reaching 25 ° C, if it does not feel cold, you can set the temperature down a few degrees Celsius, so that the high-frequency operation time of the air conditioner is short, which can save electricity. During the operation of the air conditioner, if it feels too cold, there is no need to turn it off, just turn the set temperature up
