Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to an air duct component and an air conditioner. Background Art

[0002] The positions of the air supply and return air outlets of traditional air conditioners remain relatively unchanged. However, the indoor air temperature is stratified along the height direction. High-temperature air gathers at high altitudes due to its low density, and low-temperature air gathers at low altitudes due to its high density. As a result, air conditioners with fixed supply and return air positions cannot take into account various working conditions. Under certain working conditions, there is uneven temperature stratification in the height direction (thermal stratification phenomenon), and energy saving and comfort cannot reach the optimal level.

[0003] Taking the cabinet air conditioner with upper delivery and lower return and upper delivery and lower return as an example, the air supply outlet is located at a higher position above the air conditioner. When cooling and delivering cold air in summer, the jet can quickly reach the area above the human body activity area, and then use the high density of cold air flow to sink naturally, which can achieve rapid cooling and less blowing feeling, taking into account both temperature drop and comfort effects. At the same time, since the return air outlet is located at the lower part of the air conditioner, the return air temperature is about 2°C lower than that in the middle and upper parts. Compared with the return air in the middle and upper parts, the energy-saving effect is better. However, when heating and delivering hot air in winter, due to the principle of hot air floating, the hot jet cannot come down in the upper part of the room, resulting in the phenomenon of hot top and cold bottom. At this time, only the return air temperature in the lower part is about 2°C lower than that in the middle and upper parts. Compared with the return air in the middle and upper parts, more energy is required to achieve the same outlet air temperature, and the energy-saving effect is poor. This air conditioner with fixed air supply and return air positions fails to achieve the best energy-saving and emission reduction and comfort experience in different cooling / heating conditions at the same time. Therefore, the traditional one-way inlet and outlet air circulation method cannot take into account the energy-saving and comfort needs of cooling and heating.

[0004] There is an urgent need to achieve the transformation of the air inlet and outlet circulation mode from a one-way circulation to a two-way reversible circulation. There are two ways to implement the existing reversible air supply air conditioner. One is to set up a reversible axial flow fan and control the forward and reverse rotation of the axial flow fan motor to achieve reversible air supply. This method has high requirements on the manufacturing cost of the motor, and the axial flow fan has problems such as short air supply distance and low air pressure; the other is to set up a mixed flow fan and achieve reversible air supply through mixed flow fan blades. This method has high fan speed and high noise, low workmanship efficiency, and energy saving effect does not meet the requirements. Both of the above methods have problems such as high noise and small air volume, resulting in the energy saving and comfort of the air conditioner cannot meet the requirements and cannot be commercialized. In addition, the existing reversible air conditioner has a single air inlet and outlet passage, and the air path cross-section is small and the process is long, resulting in large air inlet resistance, air volume and noise cannot meet the requirements, and the air inlet and outlet methods are not diversified enough. Summary of the invention

[0005] The purpose of the present invention is to provide an air duct assembly and an air conditioner to solve the technical problem in the prior art that the air conditioner's air supply and return air positions are fixed, resulting in the air conditioner's energy saving and comfort experience under different working conditions not being able to achieve the best at the same time.
