As you may recall, in parts one and two of the blog series we discussed several preventative steps you can take to extend the life of your HVAC system. But, there is one last and very important area to be checked on your HVAC system:::- the refrigerant charge.
For most of us, seasonal maintenance on our home’s HVAC system is not a priority. The majority of homeowners use their HVAC system until a component fails. Understanding the basics of how our home’s HVAC system functions can help us to prioritize our HVAC maintenance.
In our first post (part 1) we discussed equipment ratings and location definitions (what is a dry or wet location). In our last post (part 2) we discussed equipment that is not made to get wet, yet for some reason it does and what do you do. So, what happens when the Authority Having Jurisdiction...
In our last post we discussed equipment ratings and location definitions (what is a dry or wet location). In this post let's discuss equipment that is not made to get wet, yet for some reason it does. Does this mean it needs to be thrown away and a new one purchased? No, of course not.
It has been common in the past to assume that water and electrical equipment do not mix. However, just because a piece of electrical equipment, such as an electrical panel or a computer, gets wet doesn't mean that it needs to be replaced.
It is common knowledge that freezing water can fracture pipes; however, did you know it can also save the day?
Diesel engines are a rugged and reliable choice for propulsion and power generation. In applications where electricity is not available or may be disrupted, a Diesel engine is a good choice for providing an alternative to an electric motor for pumps. Why, then, do so many Diesel engines with...
Last year, EDT posted a blog on Ballast Water Management, and the intent of the article was to provide a synopsis of ballast water and regulations which affect the operation and equipment onboard ships. This blog is an update to keep you informed of new legislation and changes in regulations.
Beyond the obvious engineering applications or the occasional mention of a pizza or package delivery that most of us continually hear about, what sort of crazy, perhaps brilliant, drone applications have industrious problems solvers come up with? The following are three of my favorites.
To understand proper condensate removal, it is first important to have a working definition of the term condensate in the context of Heating, Ventilation, and Air Conditioning (HVAC). Most HVAC systems contain a form of refrigeration cycle which uses mechanical work acting on a fluid (in most cases...
In Part 2, we take a closer look at the crucial interactions between humans and technology. Some topics we will discuss include: Digital Information Overload, Alarm Mangement, Color, Animation, Graphics, and Layout, Industry Standards and Best Practices, and Human Factors in Design.
Can a poorly designed user interface lead to a large loss? You better believe it. Have you ever hit the wrong button on the remote control, or had trouble getting a device to work correctly because it was left in the wrong mode? Thankfully, these sort of mistakes are just mild annoyances, but when...
Freshly fallen snow is often a beautiful and awe-inspiring sight to see. Some parts of the country may see new snow daily while other areas may only see it once a century. Regardless of how prepared our cities are, snow can have a great impact on our everyday lives, particularly on our structures...
Most modern, large industrial complexes such as petrochemical and power generation facilities utilize computers to control and monitor the production equipment known as Distributed Control Systems or DCS. This insight shows how DCS works, and we explore the data provided to help identify the cause...
You may have heard the phrase “headache ball” when someone mentions a crane. Beyond the obvious explanation (imagine walking into it), what is a headache ball?
