Energy
Conservation:
In response to
ever increasing electrical grid demand, many municipalities have
mandated higher efficiencies on most mechanical cooling
equipment. With most market indicators trending towards
increases in demand for electricity, more than ever before
businesses are looking for new ways
to reduce usage and carbon emissions.
Recently, the Federal Government has put in place significant
business tax incentives to encourage investments in more
environmentally smart technologies. To see incentives

Economizer
history:
The term
Economizer is familiar to the HVAC industry as a process of
using a readily available cooling medium, such as outdoor air,
to exchange heat at a low cost. The goal of an
Economizer is to reduce the need to deploy higher cost
mechanical cooling systems that require more electrical energy. Over the years, manufacturers have
offered (Air-Side) Economizers as an option when purchasing
package air conditioning equipment.
Chiller Economizers:
Wet-side economizers have grown in popularity over the past
decade particularly in the chiller market. Up to a few
years ago, Wet-side economizers were primarily deployed on the
condenser side of water-cooled chillers to supplement cooling
towers. Until recently, application of wet-side economizers on
the process side of chillers systems was not widely considered
by U.S. chiller manufactures. Our research has shown this mainly
had to do with operational challenges that process side
deployments posed.
Evolution of Chiller Economizers
Technology:
In 2005, Legacy
Chiller Systems commissioned a feasibility study on the application
of wet-side economizers for Mission Critical chiller
applications. Our study would focus on the use of Economizers
specifically on the process side of chillers. The first tests
completed on 2006 turned out to be fair at best producing only
10% to 15% KWH reductions. By early 2007, KWH savings had
improved to 35% to 60% through the use of a new Economizer
controller and specialized software developed by Legacy's
engineering team.
In 2007, Legacy Chiller Systems Patented Chiller Economizer
Technology and now offers several products lines that take
advantage of this revolutionary technology.
Legacy Economizers
Technology Products: Legacy Chiller Systems
currently offers an Integrated Chiller Economizer and
Retrofit
Chiller Economizer solutions to the market.
Key Markets for Chiller Economizers
Technology Products: As interest in energy efficiency
products has grown, key markets for Economizer Technology
include: Data centers, MRI, CT, PET, laser and Semi-Conductor
manufacturing. In almost all cases, Economizer Technology offers
the highest return on investment when the outdoor ambient
temperatures run 5-10 degrees (F) colder than process fluid
design temperatures.
Legacy also offers some excellent research tools to assist
customers interested in Economizers. These tools include:
SystemSyzer Chiller Design
Tool, Chiller
Energy Audit Tool and many
Knowledgebase Training Aids.
