With the popularity of central air conditioners in recent years, it is no surprise that it is installed in the living room. However, a duct machine suddenly appeared recently, which made everyone wonder, what is a duct machine? What is the difference between it and central air conditioning? Let’s learn more about it with Brother Jin Flagship.
Keywords: The difference between air duct machine and central air conditioner
In fact, air duct machine is a kind of central air conditioner, which is the form of an indoor unit corresponding to an outdoor unit, which is commonly known as one tow one. The central air conditioning duct machine is better than the traditional hanger, cheaper than the 1-to-N fluorine system central air conditioner, and saves space than the air conditioner cabinet. What is central air conditioning? Both multi-connection and duct machine are central air conditioners. The indoor unit is not much different in appearance. They are both hidden in ceiling , but the air outlet of the duct machine is generally slightly smaller than that of multi-connection. The big difference between multi-connection and air duct lies in the number of outdoor units. Multi-connection is an outdoor unit that connects multiple indoor units, commonly known as one-to-N.
Simply put, its operating principle is that the air conditioner sends air to the room through the air duct. Using a high static pressure blower, the static pressure and the air supply lift are positively correlated, that is, the greater the static pressure, the longer the air supply lift. At this time, the high static pressure is used to deliver air far, but the required air ducts must be relatively long. The reason why high static pressure fans are used is to keep the wind power delivered to the room from physical loss due to wind pressure passing through the air duct, otherwise the wind power delivered to the room will be very small.
Specifically, the indoor/outdoor unit is configured in the air conditioning system of the air duct machine. The outdoor unit consists of one compressor and one air-cooled condenser, while the indoor unit consists of evaporator and a circulating fan. The condenser of the outdoor unit is used to cool the air, and the condenser and the indoor evaporator are connected through steel pipes, and then cool air is sent to each room through the indoor air supply duct, and then sent back to the indoor unit through the return air duct. At this time, the hot air is cooled and mixed with some fresh cold air and then output to the air duct, and circulates continuously. In addition, the air duct can be evenly arranged indoors according to the indoor space conditions.
Advantages of air conditioner for air ducts
1. Hideness avoids the problem of hanging up the machine and the cabinet exposed outside affecting the beauty. But at the same time, there must be a certain amount of concealment space indoors, that is, the height of the home ceiling.
2. The cost is cheap, which is compared with the central air conditioner, but the effect of decoration is similar to that of the central air conditioner, and the maintenance cost is lower than that of the central air conditioner. However, it is more expensive than hanging up the air conditioner, but it is also more high-end and more practical.
3. It is convenient to use and repair. Its system is relatively simple and does not require dedicated management. It only requires regular inspections, which is close to the thoughts of many busy people.
4. The air supply is uniform. Because high static pressure fans are used, the air pressure at the air outlet is relatively high. As long as the air duct is correctly designed, the indoor air flow can be evenly. No need to worry about the problem that people who are facing the wind are so cold, but people elsewhere are in the hot and cold.
5. Beautiful and healthy. Generally, a house only needs one host, but the air conditioner on the hang-up requires one host to be installed in each room, which occupies a space and is not beautiful. The air conditioner of the duct machine will mix some fresh air in the circulating air supply, which will improve the indoor air quality and make the family healthy for long-term breathing. If the fresh air system is installed, the effect will be better.
The insufficient duct machine
1. The duct machine consumes a relatively large power. Like ordinary air conditioners, it uses fixed frequency technology. If the turn-on time is long, the power consumption is still quite large
2. Since the duct machine system is one-to-one indoor and outdoor units, if the indoor unit is installed more, there must be enough outdoor units, which will also affect the beauty of the outdoor units.
3. The device is noisy.
duct machine is an external unit with an internal unit, commonly known as one tow one. The cost of the whole room air duct machine is about 30% cheaper than the cost of the whole room multi-connection, but multi-connection can save more outdoor unit area than the duct machine, low noise, high temperature control accuracy, and constant temperature. The multi-connection of the DC frequency conversion technology is relatively more energy-saving.What is the difference between a duct machine and a one-to-multiple central air conditioner? How to choose? The air duct machine is a main unit with an indoor unit, one tow and one, and it is relatively convenient to repair it in the later stage of use and the price is relatively cheap. However, multiple rooms are installed at the same time, and multiple air conditioning units are required to occupy multiple air conditioning units. Central air conditioning is a form of one tow and one host tow multiple internal units. It only requires one outdoor unit, so the later maintenance is more complicated. When choosing between a central air conditioner multi-unit unit and a duct machine, consider more about your permanent population, living habits, and the actual situation of the room.
If the family apartment is large in size and there are many rooms, it is recommended to choose a central air conditioner with one tow, which can save the installation location of outdoor units and make the building look better; if it is an ordinary small apartment with a limited budget but wants to enjoy the comfort of central air conditioner, or a large-area housing with a low frequency of air conditioner use, you can consider an air duct machine.
Precautions for the installation of central air conditioners Central air conditioners generally need to be determined during the decoration design drawings stage. The ceiling layout needs to be considered during design, so the number and position of the air duct machine must be determined in advance. Central air conditioners must be installed when the water and electricity enters the site. After the wall knocking is completed, the electrician needs to lay the lines according to the installation position of the air duct machine. Be sure to install the air duct machine before the carpenter enters the site. The carpenter must suspend the ceiling according to the location of the air duct and reserve the air duct.
duct machine ceiling method is more flexible Nowadays, the floor height of the house is 2.65-2.7 meters. If minus 20cm fan, 5cm ceiling, and 4cm floor, many people will mistakenly think that there is no way to install central air conditioner for ceilings. In fact, the ceiling of the central air conditioner can take a variety of forms, and the air duct machine can also use local side hanging, which can not only ensure the refrigeration effect of the central air conditioner, but also improve the overall decoration aesthetics. The installation location of the air duct machine is relatively small and flexible, with multiple air outlets and return air.
If the floor height is not very high and the ceiling space is small, you can use the side-to-side sending downwards, which saves space and is simple and generous. If the ceiling space is enough for rooms with a higher floor height, you can use the downwards and sending downwards to ensure the best heating effect; if the ceiling space is large, you can use the side-to-side sending back and returning method, which is not only beautiful, but also further reduces noise; if there is no ceiling, you also want to use a hidden machine, and you can use the appropriate ceiling space to send side-to-side sending back. Central air conditioners are born for comfort. Choose a set of central air conditioners that are more suitable for your home, and it will be cool for a summer!
