Once we distinguish voltage unbalance from voltage variation, the need to tackle the issue intelligently becomes even more clear. Learn about common causes and effects, testing for unbalanced voltages and single-phasing, and ways to correct the problem if it does manage to arise.
So many areas where a little forethought and awareness can avoid larger problems — sizing, velocity, piping and connections, double trapping, condensate return, proper pressure, blowdown tanks, and more. Read on for some good habits and why they’re worth having.
When designing or replacing a low pressure steam boiler, throw out everything you know about hydronic boilers. A steam system is closer in operation to an air conditioning unit than it is to a hydronic boiler. If you design a steam system using hydronic design methods, it will not operate properly.
Uniform Solar Energy and Hydronics Code (USEHC) contains some requirements that may be inappropriate given certain conditions, climates, or simple designer discretion. That’s not a problem … unless your locality or state adopts USECH language as binding. Dig into the problem and note a timely opportunity to avoid having these issues set in stone for another few years.
As early as 3000 BC, civilizations began to create codes for public order and safety. The Code of Hammurabi, the old “eye for an eye” law many are familiar with, also included laws for safe building construction.
There is a fair amount of press about the concept of the “Internet of Things” — or as it is commonly abbreviated, IOT. The concept of IOT is simply defined as a network of physical devices.
Spot exhaust is a unique design engineering challenge. The 2015 ASHRAE Handbook – HVAC Applicationscovers a broad spectrum of applications in just about all the comfort applications (chapters 1 through 13) and industrial applications (chapters 14 through 33) with personal safety an integral part of chapter 32. But spot return air doesn’t get much press in ASHRAE.
In our daily lives, we humans move through a sea of microbial life that is seldom perceived except in the context of potential disease and decay (L. Feazel 2009).
Continuing last month’s topic of commissioning action lists (a.k.a. master issues logs, a.k.a. corrective action lists), I would like to focus on the items in those documents that deal with construction phase or acceptance testing “deficiencies.”
A dramatic rise in the popularity of the Dominican Republic as a resort destination has led to the expansion of the principal airport serving the island’s eastern provinces, Punta Cana International Airport.
This month’s Facility File will focus on the B2B June test for an HVAC application on a college campus with a building program to construct a new 12-classroom facility. The project delivery method is integrated project delivery (IPD).
