The difference between central air conditioning and traditional air conditioning central air conditioning and traditional air conditioning which power consumption

I, the difference between central air conditioning and traditional air conditioning

1, decorative comparison

Central air conditioning: indoor machine, pipeline hidden embedded installation, occupying the upper ceiling space of the house. From the decorative point of view, the central air conditioning is hidden in the ceiling above, and thus the air conditioning do not have to consider whether and the entire home decorating the problem of incongruity, the central air conditioning aesthetics is still quite high.

Traditional air conditioning: it needs to be installed on the wall in a suitable position to punch holes, rectangular housing with the style of decoration, may be slightly abrupt; cabinet air conditioning in general also occupies almost 1_ of the space area, which may affect the indoor furniture placement of the aesthetic degree.

2, the structure of the comparison

Central air conditioning: a complete set of air conditioning system, through an outdoor unit connected to multiple indoor units, that is, the use of a tow more than one form, the internal machine installed in the living room, dining room, various bedrooms, etc., so as to address the needs of a large area of the region heating and cooling control.

Traditional air conditioning: usually one tow one, that is, an outdoor unit corresponding to the form of an indoor unit.

3, energy consumption comparison

Central air conditioning: home central air conditioning is increasingly miniaturized, the machine structure can be divided into a towing structure and multi-connected structure, a towing structure of the central air conditioning power consumption, power consumption and the same state of the wall-mounted, cabinet air conditioning, either individually open or open, power consumption and traditional air conditioning, multi-connected when all the indoor machine is fully open More energy efficient than traditional air conditioning.

Traditional air conditioning: ordinary wall-mounted, cabinet air conditioning using an outdoor unit connected to an indoor unit in the form of a separate control of each air conditioner, its energy consumption is not affected by other air conditioners, the energy-saving effect is better when turned on separately.

4, maintenance comparison

Central air conditioning: household central air conditioning service life is generally more than 15 years, in the indoor unit connected to the pipeline on the side of the reserved (350 × 350) access port, maintenance only need to open the access port can be, easy to operate.

Traditional air conditioning:? Household traditional air conditioning only need to clean the wind and net can be, the wind and filter easy to disassemble without the need for professionals to operate.

5, price comparison

Central air conditioning: there are ducted machines and auxiliary materials and so on price points of a variety of overall expensive, and the need for installation costs.

Traditional air conditioning: ordinary wall-mounted, cabinet air conditioning prices are more moderate, but the wall-mounted, cabinet prices are always higher. Traditional wall-mounted air conditioning installation does not need to decorate with the installation period is shorter, the cost is lower or even no charge.

Summary: the difference between the central air conditioning and traditional air conditioning comparison can be seen, both types of air conditioning is currently has its own characteristics, only in the beautiful decoration and room size of the room, the central air conditioning cooling/heating is more advantageous some. And traditional air conditioning is relatively speaking installation and removal, more convenient. In short, the specific central air conditioning and traditional air conditioning to choose which, according to the actual situation.

Two, central air conditioning and traditional air conditioning which consume electricity

Central air conditioning and traditional air conditioning to buy, it is inevitable that the two kinds of air conditioning in terms of power consumption will be compared to see the central air conditioning and traditional air conditioning which consume electricity. For this issue, you need to take a closer look from the point of view of power consumption and efficiency:

1, the comparison of power consumption

Home use of air conditioning people are afraid of is power, many people think that the central air conditioning is very costly, this is actually a misunderstanding. Generally speaking, the energy efficiency ratio of the central air conditioner is more than 3.0, while the ordinary air conditioner is between 2.3 and 2.8. So this is divided into several cases, in the same area range, the larger the area, the installation of central air conditioning also save electricity. But if the room is small and only one ordinary air conditioner, it is a different story.

2, the efficiency of the comparison

The efficiency of the air conditioner is the key to the experience of using it, because the central air conditioner covers a wider area, the whole house needs to be installed with a central air conditioner, and only one outdoor unit. So when running, its load is lower, and the whole machine is used with high efficiency. But if you use ordinary air conditioning, you need to install one in each room, more than one at the same time, the efficiency is very seemingly low.

Summary: for the central air conditioning and traditional air conditioning which power consumption problem, it is important to know that the horsepower of the same air conditioning, the higher the energy efficiency ratio, the lower the power consumption. Ordinary household traditional air conditioning energy efficiency ratio is 2.3 to 2.8 or so, the central air conditioning can reach more than 3.0, so the central air conditioning power consumption is not large. Some people think that the power of the central air conditioner outside the large, if only open the bedroom of the internal unit, certainly than the traditional air conditioning power consumption. In fact, it is not, a tow more home central air conditioning outside all inverter machine, power based on the inner machine conditioning. That is, open how much power, central air conditioning with how much power. Thus, from the power consumption to compare the central air conditioning and traditional air conditioning, it is difficult to compare the high and low.
