Last month, I opened a discussion on how I have enjoyed integrated project delivery (IPD) and design-build (D-B) projects over the years and how I have been fortunate to learn from other team members as I shaped my “full team participation” (FTP) process.
This month’s Facility File will focus on the B2B June test for a heating application on a college campus, with a building program removing a dormitory heating system from the campus high-pressure steam system and replacing it with a high-efficiency condensing hot water boiler within the dormitory.
A new line of dedicated outside air systems (DOAS) from the YORK® brand of Johnson Controls includes a range of 100% outside air units and mixed air units. With heat pump operation and water source operation, as well as a hot water heat option, the new line of air systems delivers more combinations of heating and cooling. The systems also feature an internal energy recovery wheel that pre-conditions outside air and reduces heating and cooling loads by transferring energy between the exhaust airstreams.
Quantech™ has added QCC2 and QCC3 air-cooled, scroll-compressor condensing units for applications ranging from 15 to 160 tons to its portfolio of ready-to-ship products. The condensing units are designed for pairing with indoor air handlers using direct expansion (DX) evaporator coils. Quantech QDC condensers and QDCF fluid coolers are also available for air conditioning and refrigeration applications as high as 2,890 MBH.
Waste heat recovery innovation doesn’t make the news that often, so when it does, I have to wonder whether you, clever reader, can steer that innovation toward some creative advancements for the HVAC industry.
Over the years of designing and building HVAC infrastructure, I’ve been fortunate to be able to complete the projects via integrated project delivery (IPD) and design-build (D-B), in addition to design-bid-build (DBB) and construction management (CM).
For years, architects have benefited from having readily available manufacturer content at their fingertips. Now it’s time for MEP engineers to start experiencing the same benefits, especially when it comes to designing with crosslinked polyethylene pipe.
In the first of a pair of articles on motor fundamentals for HVACR, the author gets into everything from industry standards and service conditions to changing speeds, enclosures, and the often misunderstood service factor. You’ll want to save this one for your team’s reference library.
The high-profile equipment involves an efficient, resilient trigeneration plant to provide heating, cooling, and power service. However, UConn’s most critical asset may be its forward-thinking, campus-wide energy strategy. Read more stories in June Issue 2017.
