Air infiltration是一个物理现象，指的是空气渗透。它通常是指空气通过墙壁、窗户、门、设备管道或其他孔隙进入建筑物内部的过程。这种现象在室内外温差较大、建筑物构造材料不密封等情况下容易出现。
空气渗透可以影响建筑物的能源效率、室内环境质量和建筑物的使用寿命。如果室内外温差较大，渗透的空气会在门窗缝隙等处结露，从而影响室内装修和设备等物品的美观和保存。同时，频繁的空气渗透也会增加建筑物的能源负荷，从而影响其能源效率。
为了减少空气渗透的影响，可以采取一些措施，如加强建筑物构造材料的密封性、使用密封条和泡沫垫等材料来填充缝隙、定期检查和维护门窗等设备等。此外，还可以考虑使用密封性更好的窗户和门，以及安装空气过滤装置和换气设备等措施来减少空气渗透的影响。
Air Infiltration Management: A Key Component of Building Energy Efficiency
Air infiltration is a common problem in buildings that can have a significant impact on energy efficiency. Infiltration occurs when air and other airborne substances enter a building through gaps in building envelopes, such as seams in walls, windows, and doors. This can result in increased energy consumption, indoor air quality issues, and potential for mold growth.
To address air infiltration, building owners and managers should implement a management plan that includes the following key steps:
1. Identify the Problem: The first step in managing air infiltration is to identify the source of the problem. This can be done by conducting a building inspection and assessing the gaps and seals around windows, doors, and other entry points.
2. Proper Sealing: After identifying the source of the infiltration, it is important to address any gaps or seals that need to be repaired or replaced. This can include repairing damaged window frames, installing weatherstripping around doors and windows, and replacing outdated or damaged seals around walls and ceilings.
3. Air Sealing Materials: Air sealing materials, such as caulk and weatherstripping, should be selected based on their performance and compatibility with the building materials and climate conditions. Properly selecting and using these materials can significantly reduce air infiltration.
4. Insulation: Adding insulation to building envelopes can help reduce air infiltration by reducing the flow of air through the building envelope. Insulation should be installed properly and maintained to ensure it remains effective.
5. Regular Inspection and Maintenance: Building owners and managers should regularly inspect building envelopes for any signs of air infiltration and repair any identified issues as soon as possible. Regular maintenance can help ensure that building envelopes remain properly sealed and insulation remains effective.
6. Building Code Compliance: Building codes can vary from region to region and should be consulted to ensure compliance with local standards. Following building codes can help reduce air infiltration and ensure energy efficiency in buildings.
In conclusion, air infiltration is a common problem in buildings that can have a significant impact on energy efficiency. By implementing a management plan that includes identifying the problem, sealing gaps, selecting air sealing materials, adding insulation, regular inspection and maintenance, and complying with building codes, building owners and managers can significantly reduce air infiltration and improve energy efficiency in their buildings.
