Does central air-conditioning really cost electricity?

Central air-conditioning is like a goddess in the air-conditioning world. Too many people want to take it home, but worry about not being able to afford it. After all, in people's traditional concept, household central air conditioners are linked by multiple machines. Turning on one host means that multiple indoor machines are activated at the same time. The electricity bill is definitely not a small amount. However, is this really the case? Today we are here to rectify the name of the central air conditioner.

1. Does central air-conditioning cost electricity?

First of all, the concept of "turning on a host is equivalent to starting multiple indoor units at the same time" has long been outdated like old tapes. Today's household central air-conditioning has flexible control, which can be controlled centrally or independently. Generally speaking, when installing a central air conditioner, each room will be equipped with a control panel, and the indoor units of each room can be adjusted at will. There is no problem of "one start and full operation".

In addition, the power consumption of household central air conditioners is mainly concentrated on compressors and fans. Because the inverter compressor is used, the energy consumption is high when it is just turned on. After it is stabilized, the electricity consumption will not be higher than that of the traditional air conditioner. On the contrary, the longer it takes, the more electricity it will be saved.

Moreover, the masters generally only use the three-strength power when they move. The central air conditioner seems to be powerful, but in actual use, these powers do not need to be used, generally only 20% to 70%.

Experience working time = daily use time * 45%Annual power consumption = annual use days * experience working hours per day * power * number of air conditioners/1000

We might as well speak with actual data. Taking three bedrooms and one living room with a construction area of 90 square meters as an example, calculate the situation that all rooms are turned on, and the central air-conditioning and 1.25-horse wall-mounted machines are used every year for three months in the first quarter. Under the same conditions, it is clear at a glance who the power consumption is high and which is low.

Second, it can save more power if you use it correctly

Although the central air conditioner does not cost electricity, if you know some tips, it will not only save electricity, but also the central air conditioner can last longer. Please keep these tips in mind:

1. Avoid direct sunlight:

People need to wear sunscreen umbrellas when they go out. Of course, the central air conditioner also needs some protection measures to shield the direct sunlight, which can save about 5% of electricity.

2. The filter should be cleaned frequently:

Too much dust will plug the mesh. The electricity used by the air conditioner is originally used to adjust the temperature. After being blocked, the air-conditioning/heating must first break through the "enchantment" composed of dust, which naturally consumes more electricity.

3. Keep the air outlet smooth:

Blocking the air outlet by large pieces of furniture will block heat dissipation and increase unnecessary power consumption.

4. Moderate temperature setting:

When the air conditioner is refrigerated, every 1°C higher the temperature can save electricity by 10%.

With major manufacturers investing heavily in central air-conditioning research and development, the energy efficiency ratio of central air-conditioning has reached a level that exceeds that of ordinary air-conditioners such as cabinet-type and split-type. The energy efficiency ratio of general household split air conditioners is around 2.3~2.8, while the energy efficiency ratio 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-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.

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.

Broaden your horizons, a set of central air-conditioning will accompany the family for a long time, and enjoy a more comfortable environment at a reasonable cost!
