Book Synopsis Do Heat Pump Clothes Dryers Make Sense for the U.S. Market by :
Download or read book Do Heat Pump Clothes Dryers Make Sense for the U.S. Market written by and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Heat pump clothes dryers (HPCDs) can be as much as 50percent more energy-efficient than conventional electric resistance clothes dryers, and therefore have the potential to save substantial amounts of electricity. While not currently available in the U.S., there are manufacturers in Europe and Japan that produce units for those markets. Drawing on analysis conducted for the U.S. Department of Energy's (DOE) current rulemaking on amended standards for clothes dryers, this paper evaluates the cost-effectiveness of HPCDs in American homes, as well as the national impact analysis for different market share scenarios. In order to get an accurate measurement of real energy savings potential, the paper offers a new energy use calculation methodology that takes into account the most current data on clothes washer cycles, clothes dryer usage frequency, remaining moisture content, and load weight per cycle, which is very different from current test procedure values. Using the above methodology along with product cost estimates developed by DOE, the paper presents the results of a life-cycle cost analysis of the adoption of HPCDs in a representative sample of American homes. The results show that HPCDs have positive economic benefits only for households with high clothes dryer usage or for households with high electricity prices and moderately high utilization.
Book Synopsis High Efficiency, High Performance Clothes Dryer by : Peter Pescatore
Download or read book High Efficiency, High Performance Clothes Dryer written by Peter Pescatore and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This program covered the development of two separate products; an electric heat pump clothes dryer and a modulating gas dryer. These development efforts were independent of one another and are presented in this report in two separate volumes. Volume 1 details the Heat Pump Dryer Development while Volume 2 details the Modulating Gas Dryer Development. In both product development efforts, the intent was to develop high efficiency, high performance designs that would be attractive to US consumers. Working with Whirlpool Corporation as our commercial partner, TIAX applied this approach of satisfying consumer needs throughout the Product Development Process for both dryer designs. Heat pump clothes dryers have been in existence for years, especially in Europe, but have not been able to penetrate the market. This has been especially true in the US market where no volume production heat pump dryers are available. The issue has typically been around two key areas: cost and performance. Cost is a given in that a heat pump clothes dryer has numerous additional components associated with it. While heat pump dryers have been able to achieve significant energy savings compared to standard electric resistance dryers (over 50% in some cases), designs to date have been hampered by excessively long dry times, a major market driver in the US. The development work done on the heat pump dryer over the course of this program led to a demonstration dryer that delivered the following performance characteristics: (1) 40-50% energy savings on large loads with 35 F lower fabric temperatures and similar dry times; (2) 10-30 F reduction in fabric temperature for delicate loads with up to 50% energy savings and 30-40% time savings; (3) Improved fabric temperature uniformity; and (4) Robust performance across a range of vent restrictions. For the gas dryer development, the concept developed was one of modulating the gas flow to the dryer throughout the dry cycle. Through heat modulation in a gas dryer, significant time and energy savings, combined with dramatically reduced fabric temperatures, was achieved in a cost-effective manner. The key design factor lay in developing a system that matches the heat input to the dryer with the fabrics ability to absorb it. The development work done on the modulating gas dryer over the course of this program led to a demonstration dryer that delivered the following performance characteristics: (1) Up to 25% reduction in energy consumption for small and medium loads; (2) Up to 35% time savings for large loads with 10-15% energy reduction and no adverse effect on cloth temperatures; (3) Reduced fabric temperatures, dry times and 18% energy reduction for delicate loads; and, (4) Robust performance across a range of vent restrictions.

Draws on the Authors’ 60+ Years of Combined Experience Fueled by the current energy crisis and growing consumer demand for improved quality products, this thoroughly updated resource addresses cutting-edge drying technologies for numerous materials such as high-valued, heat-sensitive pharmaceuticals, nutraceuticals, and some foods. It also introduces innovative techniques, such as heat-pump drying of foods, which allow both industrial practice and research and development projects to save energy, reduce carbon footprints, and thus improve the bottom line. Four New Chapters: Spray-Freeze-Drying Fry Drying Refractance Window Drying Mechanical Thermal Expression Requiring no prior knowledge of chemical engineering, this single-source reference should assist researchers in turning the laboratory curiosities of today into the revolutionary novel drying technologies of tomorrow.
Book Synopsis Clothing Wear and Tear of Heat Pump Vs. Electric Resistance Clothes Dryers by :
Download or read book Clothing Wear and Tear of Heat Pump Vs. Electric Resistance Clothes Dryers written by and published by . This book was released on 2017 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Heat pump clothes dryers are significantly more energy efficient than conventional (ENERGY STAR®) electric resistance clothes dryers. The goal of this project was to determine whether heat pump clothes dryers offer non-energy benefits—specifically, reduced clothing wear and tear—that could help consumer adoption. Multiple machine types ran over 100 dryer cycles, using loads specifically chosen to reflect a variety of fabric and fiber types. This project did not conclusively find that heat pump clothes dryers cause less wear than conventional dryers. However, the project was able to show that they do not cause more wear than conventional ENERGY STAR dryers. This project was a co-funded effort lead by Northwest Energy Efficiency Alliance with Pacific Gas and Electric. Over drying is a common occurrence in clothes dryers which are not ENERGY STAR certified and that do not have good automatic termination controls. This report contains an addendum to the Clothing Wear and Tear of Heat Pump vs. Electric Resistance Clothes Dryers study that investigated relative wear impact of heat pump clothes dryers compared to ENERGY STAR dryers. In this project additional cycles tested whether over drying from a conventional dryer caused additional clothing wear. The cycles were set to replicate the equivalent over drying that would occur in a dryer which is not ENERGY STAR certified over the course of 1-2 years. The project did not find statistically significant incremental damage to clothing from moderate over drying."--Publisher's description (viewed March 28, 2017).
