ATP FOCUSED PROGRAM:
Advanced Vapor Compression Refrigeration Systems
FY 1995 NIST Funding: $10 million
Estimated FY 1995-1999 NIST Funding: $50 million
Potential for U.S. Economic Benefit.
The technology for making things and places cooler has come a long
way since the 1920s when icemen still delivered heavy blocks of ice
from central ice-making facilities to household iceboxes. Now,
refrigerators and air conditioners are as commonplace in developed
countries as telephones and light bulbs, and they constitute big
business. Manufacturing of air-conditioning and refrigeration
equipment in the United States alone each year amounts to a $22
billion industry, which is about 40 percent of the world s
production, and employs about 125,000 people.
Conventional technology, however, is falling short on enough
engineering, environmental, consumer, and technological fronts that
refrigeration and air-conditioning engineers have entered an
innovate-or- wither phase. According to industry projections, new
demand for air- conditioning and refrigeration products by
developing countries will fatten the global market by an estimated
$150 billion over the next 10 years. With competition from Japanese
makers, who now win 40 percent of the market, and from those in
Europe, China, and Korea, the U.S. share of this emerging market
will depend heavily on who innovates faster and better. The goal of
this ATP focused program in advanced vapor compression refrigeration
systems, therefore, is to help U.S. manufacturers build the
technical basis for developing lower cost and better performing
products than all foreign competitors.
Besides bolstering industrial competitiveness for these
manufacturers, the program promises additional broad-based benefits.
Increasing the average energy efficiency of air-conditioning and
refrigeration equipment could simultaneously save industry users
billions of dollars in energy costs and significantly reduce the
emission of carbon dioxide and other pollutants as a result of
reduced fuel consumption at power plants. Moreover, the focused
program includes air-cleaning technologies, which include chemical
systems that absorb or catalytically destroy many of the indoor air
pollutants thought to be responsible for the "sick building"
syndrome. The Environmental Protection Agency estimates that as many
as 50 percent of commercial buildings have problems with their
indoor air and that improving air quality could yield annual savings
of several billion dollars in the form of improved worker
productivity, decreased public health costs, and reduced maintenance
costs.
Technology Challenge.
The key to success for U.S. corporations in future international
competition in this sector will be the ability to develop more
efficient, quiet, and compact air-conditioning and refrigeration
systems with the lowest achievable environmental impact.
The technical challenge centers on the vapor compression cycle,
which is the principle of operation for the vast majority of cooling
equipment now manufactured and in use both in individual residences
and in industrial settings. During the cycle, liquid refrigerants--
among them the soon-to- be-phased-out chlorofluorocarbons (CFCs), as
well as their replacements--expand in a metal coil. This is an
energy-absorbing process that extracts heat from the space to be
cooled. A mechanical compressor then consolidates the expanded gas
and pushes it into a condenser where the vapor liquefies, which is
an energy-releasing procedure that prepares the refrigerant for
another run of the cooling cycle while releasing the heat associated
with the condensation process away from the cooling system. The
overall technical goals are to increase system efficiency by 25
percent, to reduce the noise levels and size of refrigeration
components by the same amount, and to design and manufacture a
system in which no refrigerant leaks.
Better efficiency translates into lower operating costs for users
and less environmental impact. Compactness and quiet operation are
critical user- convenience factors in the competition for the global
consumer base. The no-leak goal is important for several reasons.
One is to reduce maintenance costs due to leakage, which has been a
chronic problem for decades. Another reason leakless systems are
necessary is that new, more environmentally friendly refrigerants
often consist of several components that can escape from leaky
systems with different degrees of ease, yet the system's optimal
efficiency depends on maintaining the chemical uniformity of the
refrigerants.
Industry Commitment.
Following several meetings and workshops of industry members in
1994, the air-conditioning and refrigeration industry approached
NIST with a proposal for an ATP focused program. Industry spends
about $63 million each year on R&D, almost all of which is devoted
to product changes associated with the imminent phaseout of CFCs,
efficiency improvements mandated by energy legislation, and testing
candidate refrigerants for their long-term potential to affect the
global climate. In December 1993, 170 companies represented by the
Air Conditioning and Refrigeration Institute submitted a "white
paper" to the ATP articulating the riskier technological challenges
their industry faces, the commercial opportunities these advances
could create, and their eagerness to share the costs in a program
that would greatly leverage their own commitment.
Significance of ATP Funds.
Most of each company's R&D resources are devoted to
environmental and regulatory needs and the international agreement
to phaseout CFCs. By providing a solid basis for industry
collaboration on high-risk, cutting-edge technologies, the ATP can
catalyze development that no individual company can undertake. ATP
support will assist the industry in its own efforts to get a jump on
the emerging worldwide markets that are rapidly developing.
