In modern home decoration, air conditioning, as an essential electrical appliance to regulate indoor temperature, has a variety of types and forms. Among them, the air duct machine is gradually favored by more and more families with its unique beauty and practicality. This article will introduce the composition and working principle of the air duct machine in detail, as well as its advantages and disadvantages, to help you understand this air conditioning equipment more comprehensively.
1. The basic composition and working principle of the air duct machine.
The air duct machine, also known as the air duct air conditioner or simple ** air conditioner, is mainly composed of two parts: the outdoor unit and the indoor unit. The two parts are connected by copper pipes to form a closed circulatory system. The outdoor unit is responsible for absorbing and releasing heat, while the indoor unit transports heat through the refrigerant in the copper tube, and finally releases heat or cooling capacity indoors, so as to achieve the purpose of adjusting the indoor temperature.
Specifically, when the air conditioner is in refrigeration mode, the compressor in the outdoor unit compresses the gaseous refrigerant at low temperature and low pressure into a gaseous refrigerant at high temperature and high pressure, and then conveys it to the indoor unit through a copper pipe. In the indoor unit, the gaseous refrigerant with high temperature and high pressure becomes a liquid refrigerant after being released by the condenser, and then becomes a liquid refrigerant with low temperature and low pressure after being depressurized by the expansion valve, and finally absorbs the heat in the room through the evaporator and vaporizes it, so as to achieve the effect of cooling. On the contrary, when the air conditioner is in heating mode, the compressor in the outdoor unit compresses the gaseous refrigerant at low temperature and low pressure into a gaseous refrigerant at high temperature and high pressure, and then conveys it to the indoor unit through a copper pipe. In the indoor unit, the gaseous refrigerant with high temperature and high pressure releases heat and becomes liquid refrigerant, and then becomes a liquid refrigerant with low temperature and low pressure after being depressurized by the expansion valve, and finally releases heat into the room through the evaporator, so as to achieve the effect of heating up.
In addition, the air duct machine also has a one-to-one form, that is, an outdoor unit corresponds to an indoor unit. This form of duct machine is suitable for the air conditioning needs of a single room. At the same time, according to the different installation conditions, the duct machine is also divided into three models: low, medium and high static pressure to meet the installation needs of different occasions.
Second, the aesthetics of the air duct machine.
The effect of the air duct air conditioner after installation is similar to that of the ** air conditioner, all the refrigerant pipes, drainage pipes and line pipes, as well as the indoor unit are hidden in the ceiling. This makes the indoor space more neat and beautiful, and avoids the visual discomfort caused by the exposure of the indoor unit of the split air conditioner. At the same time, the air outlet and return air outlet of the indoor unit can be customized according to the decoration style, which integrates with the indoor environment and improves the overall aesthetics. In addition, the control of the indoor air conditioner can be carried out by wire control and remote control, which is convenient and flexible to operate.
Third, the practicability of the air duct machine.
*Affordable: Compared to **air conditioner, the ** of the air duct machine is much cheaper. The high-power air duct machine is almost the same as that of the split air conditioner, so that more families can enjoy the comfortable experience of air conditioning. At the same time, the low-power air duct machine is not much different from the ordinary hang-up, which meets the needs of different consumers.
Uniform air supply: Since the air conditioner of the air duct is installed in the ceiling, its air outlet can radiate a long distance. Moreover, the size of the air outlet and return air outlet are relatively large, as long as the air duct is correctly designed and installed, the uniformity of air supply is very high. This makes the indoor temperature distribution more even, avoiding the problem of uneven air supply of traditional air conditioners.
Space-saving: The indoor unit of the air duct air conditioner is hidden in the ceiling and will not occupy wall or floor space. This is a great advantage for small homes or families with limited space. At the same time, the thickness of some duct machines is only 185mm, which occupies less indoor floor height, which reduces the installation pressure of the ceiling height.
Easy maintenance: The system of air duct air conditioning is relatively simple, with an outdoor unit dragging an indoor unit. This allows the indoor unit and outdoor unit to be cleaned and serviced independently, requiring only regular inspection and maintenance. This significantly reduces the cost and difficulty of repairs.
Flexible installation location: The installation of the air duct machine is similar to that of the air conditioner, and it can be installed anywhere in the room. The effective length of copper pipes is longer than that of body air conditioners, and can be flexibly installed according to the location of the indoor unit and the outdoor unit and the decoration layout of the construction site. At the same time, there are also a variety of options for air outlet and return air, which makes the installation position more flexible and diverse. This enables the duct machine to adapt to a variety of complex decoration environments and needs.
Fourth, the deficiencies of the air duct machine.
While duct machines have many advantages, there are also some drawbacks to be aware of:
Noise problem: Due to the high static pressure value of the air duct and the fixed speed fan used in some models, it may produce large noise during operation. However, with the continuous advancement of technology, many air duct machines have now adopted frequency conversion technology to reduce noise. At the same time, adding air ducts can also effectively reduce the impact of noise on indoor life.
Larger power consumption: Compared with ordinary air conditioners, the power consumption of air duct machines is relatively large. This is mainly due to the fact that some duct machines use fixed-frequency technology. However, with the wide application of frequency conversion technology, many new air duct machines have been greatly improved in energy consumption. Of course, the use of inverter technology will also make the retail ** of the duct machine slightly higher than the fixed frequency model.
The number of outdoor units is large: Like the split air conditioner, the number of outdoor units of the air duct air conditioner needs to be corresponded one-to-one. This means that the installation of a duct in each room requires an outdoor unit and the corresponding installation location. For large areas such as living rooms and restaurants, it may be necessary to use multiple air duct units, so the number of outdoor units will be relatively large. This increases the complexity and cost of installation and maintenance to a certain extent.
5. Summary and outlook.
To sum up, as a beautiful and practical air conditioning equipment, the air duct machine has a wide range of application prospects in modern home decoration. Its unique concealed installation, uniform air supply effect and flexible installation position make it able to meet a variety of complex decoration needs. At the same time, with the continuous progress of science and technology and consumers' pursuit of comfortable quality of life, it is believed that in the future, air duct machines will make greater breakthroughs and innovations in energy saving, noise reduction, intelligent control, etc., bringing more comfortable and convenient experience to our lives.
