Why is the duct air conditioner not a central air conditioner
Many people think that the air duct machine is also a central air conditioner. Strictly speaking, this understanding is actually wrong. Ducting machine is the abbreviation of concealed air conditioner. It can also be called air-conditioning ducting machine or ducted air-conditioning. It is also called ducted central air conditioner.
The indoor unit of the air-conditioning duct machine is basically the same as the indoor unit of the central air-conditioning unit, and both adopt the form of a ceiling. From the appearance, there is no difference from the central air-conditioning. Why is the duct-unit air-conditioning not a central air-conditioning?
Because the air duct machine is an external machine and an internal machine, it is usually fixed frequency (now also has variable frequency), and the central air conditioner is generally in the form of one towing. Moreover, the ducted air conditioner cannot achieve the use effect of the central air conditioner. So it is not really a central air conditioner. Today, I will give you a detailed explanation of the difference between air duct machines and central air conditioners.
The difference between air duct machine and central air conditioning
duct machine
1. The air duct machine is one for one, and one main engine is for one internal machine. The price is relatively cheap, usually fixed frequency, and now there are frequency conversion. The energy efficiency is low and the noise is relatively loud.
2. The air duct machine solves the problem that the main body of the wall-mounted and cabinet air conditioners is exposed in the space, and is beautiful and generous. The duct machine is a concealed air conditioner, which is installed in the ceiling. It must be constructed after the water and electricity enter the site, and the design and power wiring must be done before decoration.
3. The duct machine is easy to maintain. One host is equipped with one indoor machine. The air duct machine is suitable for use in independent large rooms, such as the halls of shopping malls and restaurants (but not for private rooms), with good effect and low price.
Central air conditioning
1. The central air conditioner has multiple internal units, one host can drag multiple internal units; the more central air-conditioning internal units are turned on, the more obvious the power saving advantage will be, and the advantages will be reflected when it is turned on above 40%, and the comfort will be higher and the noise will be relatively high. Smaller. But the price is high, and the prices of major brands are different.
2. The central air conditioner only needs one outdoor stand. If it is a one-for-five air conditioner, the energy consumption is slightly higher than that of a one-for-one household machine. The more internal units are opened, the better the power saving effect.
3. Once the central air-conditioning fails, the air-conditioning system of the whole house is paralyzed, and the maintenance cost is higher than other air-conditioning types.
Compare the pros and cons
Ducting machine: Ducting machine is relatively cheap, usually fixed frequency (now there are frequency conversion, less), energy efficiency is lower, the noise is also relatively large, and if there are more rooms, it needs a lot of places to place the outside machine, this It makes sense to follow the cabinet machine.
Central air-conditioning: The process of central air-conditioning is a little more advanced than that of air duct machines, with high frequency conversion energy efficiency and relatively low noise. There is only one outdoor machine, so the space required will be less.
Central air-conditioning: If air-conditioning is used in the whole house, at this time, the central air-conditioning only uses one outdoor unit, and there are multiple duct machines, which saves more power than central air-conditioning.
Ducting machine: If only one room uses air conditioner, then the ducting machine only needs the corresponding outdoor machine to operate, while the central air conditioner is a whole large outdoor machine running. Although the speed is not high, the power consumption will be higher than that of a single machine. There are a lot more outside air duct machines.
Therefore, when choosing an air conditioner, consider the permanent population and living habits of your home, as well as the actual situation of the room.
