Cooling coil condensate is an extremely important part of commercial HVAC system design and should be carefully considered to avoid major issues. Incorrectly designed and installed trap and condensate piping can lead to issues caused by:
Creating certain chemicals requires precise temperatures to ensure the chemical reaction yields the highest concentration of product. The addition of larger heat exchangers at a Midwest U.S. chemical processing and distribution company resulted in increased capacity for its chemical production.
It also caused significant strain to its aging water system. An inability to keep up with the increased load resulted in inefficient product temperatures, as well as frequent and costly service to the pumps. Each time the pumps went down, production was halted for maintenance.
For a growing chemical processing and distribution company that was experiencing downtime and costly repairs, Grundfos’ Hydro MPC BoosterpaQ — featuring the new CR 95 — offered the perfect solution.
Filters are ubiquitous in air handling systems, so it’s helpful to understand the different options for filters and to learn about how they function. Almost every air handling system has some level of air cleaning capability.
Air filtration refers to removing airborne particles using media filters. From a high level, air filtration is provided in a heating, ventilation and air conditioning system for two main reasons: to protect equipment components from accumulating dirt/debris and to reduce the quantity of air contaminants inside the building environment.
Refabrication and modular construction have grown over the last few years as a solution to the problem of trade workforce shortages. These building methods are almost universally agreed to be advantageous because they improve:
• Productivity
• Quality
• Schedule certainty • Cost predictability • Waste reduction
• Client satisfaction
• Safety performance
Entry-level consulting engineers should understand the definition and applications of a commercial hydronic boiler. The hydronic boiler is the heart of the hydronic heating system. The heating system consists of many parts including the boiler itself, the piping distribution, pumps, central and terminal devices that deliver the hot water to where it’s needed and building automation systems to control how much heat is being delivered. The boiler is a pressurized vessel that burns combustible fuel to heat water that is used to heat a commercial building.
