Gary McCready: 我很好奇,对于想要将Aeroseal整合到自己服务的HVAC承包商来说,这需要怎样的流程?成为Aeroseal经销商的途径是什么?为什么这项技术对住宅和商业应用都非常有价值?还有,Aeroseal是如何工作的?它能处理多大尺寸的泄漏?安装机器的最佳位置在哪里?在密封过程中如何保护线圈和热交换器?建筑科学界对管道密封技术的进步有何看法?Aeroseal是如何帮助大型商业项目和特殊应用的?使用Aeroseal后,还会残留多少泄漏? Mark Modera: 住宅改造或新建项目中,Aeroseal的安装需要经过专业培训的人员进行,并非DIY项目。目前美国和加拿大有超过500家服务商提供Aeroseal服务,他们可能是各种类型的承包商。Aeroseal的安装成本信息需要联系服务商获取。想了解Aeroseal的定价或培训,可以直接联系Aeroseal公司。Aeroseal的密封原理主要基于物理学,通过产生固态粘性密封球来堵塞泄漏。Aeroseal密封球的大小选择至关重要,需要根据喷嘴设置和气流速度来控制。Aeroseal的工作原理是利用气流将密封球带到泄漏处,密封球撞击泄漏处并堆积,从而堵塞泄漏。Aeroseal的实际密封极限在3/8英寸到5/8英寸之间,但密封效率与泄漏尺寸的平方成反比,密封一个1英寸的孔比密封一个1/8英寸的孔所需时间长64倍。Aeroseal设备通常安装在送风机附近,新建筑安装在设备安装前,旧建筑需要在设备附近开孔安装。Aeroseal密封过程应避免接触炉子或空调的换热器,尽管意外接触可能会导致异味,但不会造成永久性损坏。建筑科学界对Aeroseal技术的了解程度不一,但长期以来,Aeroseal一直是建筑科学界的一部分。Aeroseal技术在大型商业项目中也得到了应用,例如密封大型排气管道。Aeroseal的目标是让更多人了解并将其纳入日常业务流程。Aeroseal通常可以密封90%的泄漏,但要达到完全气密需要额外的措施。在特殊情况下,Aeroseal可以将泄漏率降低到接近零,但通常情况下,泄漏率会降低到1%左右。进一步降低泄漏率的性价比会下降。

Shownotes Transcript

In this episode of HVAC Know It All Podcast, host Gary McCreadie) continues his conversation with Dr. Mark Modera), The Inventor of Aeroseal), Professor at the University of California, Davis), Visiting Faculty at Berkeley Lab) and Former Vice President at Carrier HVAC). In this Part 02 they discuss how HVAC contractors can integrate Aeroseal into their services, the process of becoming an Aeroseal dealer, and why this technology is a valuable addition for residential and commercial applications. Dr. Mark Modera explains the science behind Aeroseal, The Invention of him. how the sealant particles work to close duct leaks, and the limits of what size leaks can be sealed. They also cover how the building science community views duct sealing, the impact on HVAC Performance improvement, and why reducing duct leakage is essential for system performance and energy savings. This discussion provides valuable insights for HVAC professionals looking to expand their services and improve system performance with modern sealing techniques.

Dr. Mark Modera discusses the challenges HVAC contractors face with duct leaks and why traditional sealing methods fall short compared to modern solutions like Aeroseal. He highlights the importance of measuring and verifying duct leakage, the need for continuous education in building science, and how technology is making duct sealing more accurate and accessible. They also explore how HVAC contractors can become Aeroseal dealers, the business opportunities it presents, and how proper diagnostics and sealing techniques can smooth system performance while reducing energy waste.

This episode is filled with practical HVAC insights, business opportunities, and advanced sealing techniques, helping technicians understand duct leaks, enhance system performance.
