At present, most household central air conditioning brand series are mainly towed (multi-online), and the sales volume of the most typical split air duct machine is not a few. So, the question comes, home improvement central air conditioning is to choose a drag more or a drag a good? In fact, there is no good or bad, but it depends on the type of apartment and the needs. Today Xiaobian from the following aspects to analyze, I hope to help you.
1. Comparison of energy consumption
One drag one (air duct machine) is an indoor unit and the corresponding outdoor unit for an independent system, the outdoor unit power is small, each room of the internal and external units are separately controlled, its power consumption is similar to traditional air conditioning.
A multiplex (multi-line) is a system composed of multiple indoor units and an outdoor unit. The system collocation principle is that the cooling parameters of the outdoor unit and the cooling parameters of the indoor unit are equal, or the indoor unit has appropriate supermatching. The air conditioning in each room can be individually controlled. When the indoor unit is fully turned on, the power saving is more than one drag, and when a room is opened separately, the traditional air conditioner or the central air conditioner of the air duct structure is more power saving.
2. Comparison of configuration flexibility
One drag one (duct machine) flexible configuration, from a single room apartment, guest restaurant, two rooms, three rooms, and even duplex, villa, it can find suitable solutions; At the same time, the air conditioner of one drag and one structure can also be mixed and used with one drag.
The power of the outdoor unit is generally large, and the indoor unit is determined according to the actual needs of the room, but it is limited by the power of the outdoor unit, and its configuration flexibility and application scope are not as good as that of the household central air conditioner with a drag and a structure.
3. Outdoor unit comparison
One drag one (air duct) is an outdoor unit connected to an indoor unit, the number of outdoor units is the same as the traditional air conditioner, small size, can be installed in the air conditioning space reserved for the apartment, for the use of green balcony at home to give up valuable space. At the same time, prevent the outdoor unit from interfering with daily life.
A drag (multi-line) is an outdoor unit connected to multiple indoor units, the number of outdoor units is small, compared with the outdoor unit volume is larger, resulting in it in the general apartment room reserved for air conditioning can not be installed, can not be installed on the balcony. During the installation, it is best to keep the outdoor unit of the air conditioner away from the bedroom as far as possible.
4. Maintain comparison
Whether it is a drag one (duct machine) or a drag more (multi-line) in a long time of 8 to 12 years of high pressure environment operation, the life of the refrigerant pipeline is a key factor affecting the refrigerant system. The multi-drag structure must be distributed from one outdoor unit to each indoor unit by a split pipe or a split box. The pipeline is simple and relatively shorter (the pipeline is more than a certain distance is the reason for the decay of the refrigerant effect), and the regular household central air conditioning installation company will take the whole copper pipe without welding in the middle to connect the indoor and external machine (the joint part can be directly repaired).
Therefore, compared with one drag (air duct machine), the failure of the air conditioner of one drag (multi-line) structure is more affected by human factors, and the indoor unit and the indoor unit are a whole system, and once a problem occurs in the indoor unit, it is easy to affect the entire system. The indoor unit and outdoor unit of one drag structure are independent systems, which are safer and simpler to use and maintain in the later stage.
PS: If the permanent resident population of the home is only two people, the air conditioning is opened for a short time, and the room is more, then you can consider installing a drag (duct machine); If the family resident population is relatively large, the air conditioning is turned on frequently, then the installation of a drag (multi-online) system is more worthwhile.
For a house below 80 square meters, it is not recommended to choose a drag (multi-online), you can consider a drag (duct machine). Moreover, the ceiling method is more flexible, and the duct machine can also use local side hanging, which can not only ensure the central air conditioning cooling effect, but also improve the overall decoration beauty.
