Environmental factors, IAQ-related codes and standards, even architectural building materials … a lot of factors combine to create a moving target for designers of good humidification systems. That’s not even considering the potential hiccups lurking in the construction process or resulting from an inattentive project team member. From the humidity basics to equipment placement to post-occupancy maintenance that can thwart lawsuits, pursue the path to appropriate humidity and minimal risk.
Does an old-school concept deserve consideration for a wider range of projects these days? After a refresher on the basics, warm up to a variety of current tips and advantages for
maintenance, controls, and installation.
Modular boilers have come a long way in the past few years, along with load-matching strategies. Improving efficiencies, navigating critical tight spaces, and allowing for future growth are three reasons this option is heating up.
Recovering sensible or total heat, wheels or cubes, optional add-ons like fans and filters and assorted sensors ... it takes some homework to specify the right energy-saving recovery ventilator for your school application.
Earthquakes and strong gusts are threats in the physical world that creep into the HVAC design world of isolators, supports, and special louver considerations. Furthermore, a new legal world in terms of codes, insurance, and liability can leave inattentive engineers, owners, and manufacturers quaking in their boots. Read on to stay safe in more ways than one.
Terminal devices, pressurization, supply air, proper exhaust … those factors and more go into a well designed VAV system for sensitive lab applications. From general tips to changing details such as fabric duct elements, booster fans, and a new AMCA standard, the author equips you to succeed in one space that is no place for experimentation.
reviewing the methods and pros/cons of various hood designs, the
author moves on to ventilation alternatives, details like equipment
placement and insect control, and maintenance tips. Finish up with a
design checklist that will never go stale, garnish with reading
recommendations, and you’re ready to serve up a healthy design the
next time an order is placed.
Many engineers tend to avoid or delegate the nitty gritty of a ground source heat pump system, from soil moisture effects to building system (im) balance. It's time for designers to get in the loop.
