Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ventilation ducts, in particular to a heating, ventilation and air conditioning duct that is convenient to install. Background Art
[0002] In the early days, the ventilation of buildings mainly relied on natural ventilation. With the improvement of people's requirements for the comfort of the indoor environment and the increasing complexity of building structures, simple natural ventilation can no longer meet the needs. The emergence of air conditioning technology has made it possible to adjust the temperature and humidity of the indoor environment. However, to achieve the effective distribution of air indoors, the ventilation duct system has become crucial. With the progress of materials and manufacturing technologies brought about by the Industrial Revolution, the improvement of metal processing technology has enabled the manufacture of more robust and better-sealed ventilation ducts. At the same time, the in-depth research on fluid mechanics and thermodynamics has provided a theoretical basis for the design of ventilation ducts, enabling more accurate calculation of air volume, air velocity, and pressure loss, and optimizing the layout and size of the ducts. The rapid development of the construction industry, the increase in high-rise buildings and large public buildings, has put forward higher requirements for the performance and complexity of ventilation systems. The development of electrical control technology has made it possible to precisely control and adjust equipment such as air valves and fans in ventilation ducts through an automated system to adapt to different usage scenarios and requirements. In recent years, with the enhancement of environmental awareness and the emphasis on energy efficiency, the energy-saving design of ventilation ducts and the application of new insulation materials have become research hotspots to reduce energy consumption and environmental impact.
[0003] Air conditioning ventilation ducts are an important part of the air conditioning system for transporting air. Its main function is to evenly distribute the processed (such as cooled, heated, humidified, dehumidified, etc.) air to each room or area, and at the same time discharge the dirty air indoors to the outside to maintain the quality and comfort of the indoor air. Air conditioning ventilation ducts are usually made of metal (such as galvanized steel sheets, stainless steel, etc.), plastic (such as PVC), or fiber-reinforced composite materials, etc. Its shape can be rectangular, circular, or oval, depending on the installation space and design requirements. The design of ventilation ducts needs to consider multiple factors, including air volume, air velocity, pressure loss, noise control, space layout, etc. A reasonable design can ensure smooth air flow in the duct, reduce energy loss and noise generation. In terms of installation, the ventilation duct needs to be firmly fixed to the building structure to avoid vibration and loosening. The connections of the ducts should be well-sealed to prevent air leakage and affect the performance of the air conditioning system. Air conditioning ventilation ducts also need to be regularly maintained and cleaned to remove dust, dirt, and microorganisms in the ducts to ensure clean and hygienic air.
[0004] There are some prominent problems with existing heating and ventilation pipes. First, the seals at the pipe joints are not tight enough, or the pipes themselves are damaged, which can easily cause air leakage. Such leakage not only has an adverse effect on the ventilation effect, making the indoor ventilation unable to achieve the expected uniformity and sufficiency, but also disrupts the pressure balance of the system, resulting in unstable operation of the entire ventilation system. Second, the heat insulation performance of the pipes is poor. During the process of transporting hot air, a large amount of heat will be lost due to insufficient insulation. This significantly reduces the utilization efficiency of thermal energy, increases energy consumption and cost expenditure. Summary of the Invention
