Does the central air conditioner consume electricity?

1. Whether it consumes electricity, first look at the energy consumption ratio

With the large investment in research and development of central air conditioners by major manufacturers, the energy efficiency ratio of central air conditioners has reached the level of surpassing that of ordinary air conditioners such as cabinet type and split type. The energy efficiency ratio of general household split air conditioners is around 2.3~2.6, while central air conditioners can reach more than 3.3. This means that at the same temperature, the power consumption of household central air conditioners is lower than that of ordinary cabinet-type and split-type air conditioners.

In addition, the central air conditioner can also be used with a wall-hung boiler, and it can also use ground source heat pump technology to increase the energy efficiency ratio to more than 5. So from this point of view, the power consumption of household central air-conditioning is not large. Shanghai Central Air Conditioning Project

2. It is a misunderstanding that it consumes more electricity than traditional air conditioners

From a functional point of view, a household central air conditioner is equivalent to several wall-mounted and cabinet units, and its electricity consumption is less than the sum of the electricity consumption of one air conditioner installed in each room, but the effect is better than the effect of installing several units. The cost is much lower than the split air conditioner; the central air-conditioning refrigeration station can directly control the on-off time and cooling capacity of the chiller, and can be adjusted according to climate changes 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, cabinet-type split machines, and the electricity bill is much lower than the heating bill. Whether in terms of performance, appearance or overall use effect, central air conditioners are superior to traditional air conditioners. Shanghai air conditioning design

3. Then, how can the air conditioner be used to save electricity?

In fact, power consumption is related to many factors such as the number of people in the room and the airtightness of the room. Generally speaking, air-conditioned rooms must be airtight well, and windows must be closed tightly during use to keep the air-conditioning from losing; indoor personnel are better not to enter and leave too frequently; if the room is too bright, 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 cost electricity, thinking that it will save electricity after turning it on for a while and turning it off for a while. On the contrary, when the air conditioner is started, the high-frequency operation instantaneous current is large, the frequent switching of the power consumption, and the loss of the compressor, so do not use frequent switching to adjust the room temperature.

Fourth, what is the correct use of central air conditioning?

The correct method of use is: when setting the room temperature, do not have too much difference with the outdoor temperature. For example, the outdoor temperature is 30°C, and the indoor setting is 25°C. After reaching 25°C, if you feel that it is not cold, you can lower the set temperature a few more times. Celsius, so that the air conditioner has a short high-frequency operation time and can save electricity. During the operation of the air conditioner, if it feels too cold, there is no need to turn it off, just increase the set temperature.
