Residential Gas Cooling: A Life-cycle Approach

Richard L. Itteilag and Christina A. Swanson

Year: 1986
Volume: Volume 7
Number: Number 4
DOI: 10.5547/ISSN0195-6574-EJ-Vol7-No4-5
View Abstract

The outlook for increased gas cooling use has not only improved because the residential air conditioning market in general has grown but also because many of the factors that depressed gas air conditioner sales earlier have been eliminated. First, the gas cooling equipment available today is more reliable and durable than before. During the 1960s, deficiencies in the gas absorption air conditioner caused an annual failure rate of about 8 percent. It is now less than 1 percent due to a number of improvements implemented by Arkla Industries during the 1970s. For example, the stainless steel generators in the units were improved with chrome plating, which prolongs the system life of the units. The quality of the steel in the restrictors, burner tubes, and evaporator coils was also improved. Residential gas air conditioners now carry a ten-year warranty on all defects in material and workmanship on the sealed refrigeration unit, while a compressor in an electric air conditioner normally has only a one- to five-year warranty.

Anticipating Air Conditioning's Impacton the World's Electricity Producers

Clinton J. Andrews

Year: 1989
Volume: Volume 10
Number: Number 3
DOI: 10.5547/ISSN0195-6574-EJ-Vol10-No3-7
View Abstract

Electric power planners in developing countries have the oppor-tunity to anticipate air conditioning-induced demand peaks, rather than merely react to them, as has happened in the United States. Demand-side management activities targeting future air conditioning installations therefore may be warranted, based on economic efficiency considerations, the U.S. experience, and worldwide trends in air conditioning usage. The feasibility of such anticipatory efforts is likely to hinge on local parameters, including domestie energy supplies, foreign exchange and capital constraints, rates of load growth, evidence of impacts on load profiles, and familiarity with demand-side planning concepts.

Stretching the Duck: How Rising Temperatures will Change the Level and Shape of Future Electricity Consumption

Nicholas Rivers and Blake Shaffer

Year: 2020
Volume: Volume 41
Number: Number 5
DOI: 10.5547/01956574.41.5.nriv
View Abstract

This paper examines how rising temperatures due to climate change will affect electricity consumption patterns through mid- and end-century. We extend recent literature in two important ways. First, we directly incorporate adaptation in the form of increased air conditioner penetration, resulting in heightened responsiveness to hot temperatures. Second, we go beyond average effects to consider how higher temperatures will change the intraday and seasonal shape of consumption. This is found to be of greater importance in colder countries, where the average effect is dampened by reductions in heating demand from warmer winters. Seasonal peaks are projected to shift from winter to summer and the diurnal range of hourly consumption expands, exacerbating an increasing need for flexibility coming from the supply side due to a growing share of renewable energy.
