Granite State Chapter of ASHRAE
Press Release
December 6th, 2017
 

The Granite State Chapter of ASHRAE and Chapter 140 of the Association for Facilities Engineering held their annual joint meeting at Veiga’s Training Center in Nashua on December 6th. Over fifty members and guests attended the combined vendor show and technical presentations. Thirteen vendors had table top displays where people could learn more about their products and services and there were three, 45 minute technical presentations that included representatives from the State’s Department of Environmental Services and two industry spoke persons. See below for details. The event included a buffet dinner provided by Veiga.

           



 

Vendors: Tower Hill Sales, F.W. Webb, Revision, Mitsubishi, Alliance Mechanical, Buckley Associates, ALBO Agency, Sterling Moving, Filter Sales and Service, Viega, Lightec, Anchor Insulation, Henry Scarano

Technical presentations:

Daryl Schoellkopf from F.W.Webb presented an overview of design issues with steam systems. The main takeaway was that most problems with steam systems, i.e. water hammer, were traceable to poor design of the piping systems. Daryl showed an video clip of how water hammer nearly cost a millwright, standing in a manhole above 125 psig steam pipes nearly lost his life when a steam line blew out below him due to water hammer.

Mark Ledgard-Compliance Programs Administrator with the NHDES Air Resources Division, explained the ins and outs of bringing free standing, wood fired boilers into compliance with EPA emission standards for particulates and VOCs. And Mark’s office handles complaints from neighbors due to excessive smoke from wood fired boilers. These boilers, unless grandfathered-in, may not be installed or even relocated on the original owner’s property if the boiler doesn’t meet current rules. A typical wood fired boiler that meets the prevailing EPA emission standards costs upwards of $10,000, not including installation.

Paul Giurlando of Fluid Equipment Solutions of New England presented a detailed explanation of how energy savings & equipment first cost reduction could be had by substituting multiple, smaller pumps, e.g. two or three pumps operating in parallel rather than the more typical 100% duty- 100% standby larger pump arrangement. Typical building HVAC load profile and operation were reviewed to demonstrate how advancements in technology (demand controlled ventilation, occupancy sensors, etc.) reduce anticipated peak loads and increase hours of operation under park load conditions. Since most pumps used for HVAC applications operate at part loads 90% of the year; pump selection stagey was discussed and reviewed to demonstrate how optimizing the pump efficiency for peak efficiency at part load conditions (when the pump will operate most hours of the year) results in energy savings for the life of the equipment.
