Download or read book Analysis and development of regenerated desiccant systems for industrial and agricultural drying written by D V. Merrifield and published by . This book was released on 1977 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results are presented of a research and development effort to further develop and improve the design of a regenerated desiccant drying and dehumidification system which has more than twice the energy efficiency of conventional warm air dryers. The baseline application is for large-scale commercial grain drying, although several other applications have been identified such as space air conditioning and kiln drying of lumber. The system has excellent potential for providing a significant degree of industrial energy conservation while incurring payback periods of two to eight years to recover the added capital investment over conventional less-efficient drying methods. Although the intended energy source for the system is solar energy, the basic energy saving technique is the liquid desiccant drying process itself such that virtually any thermal energy input can be used. The use of solar energy permits further energy conservation if the additional capital investment is justified. The major goal of the present study has been to improve the cost effectiveness of the desiccant regeneration system and establish significant design improvements over the regenerated desiccant drying concept developed in previous study phases. This goal has been achieved through the use of a straightforward evaporative technique for regenerating (reconcentrating) the lithium chloride desiccant solution, in place of using the previous packed column technique, and by using a steam condenser for heat recovery. The use of this technique resulted in a system cost reduction of nearly one-third and an efficiency improvement of approximately 10%, as well as a reduction in system size and complexity.

Available in PDF, EPUB and Kindle. Book excerpt: Desiccant cooling is an important part of the diverse portfolio of Thermally Activated Technologies (TAT) designed for conversion of heat for the purpose of indoor air quality control. Thermally activated desiccant cooling incorporates a desiccant material that undergoes a cyclic process involving direct dehumidification of moist air and thermal regeneration. Desiccants fall into two categories: liquid and solid desiccants. Regardless of the type, solid or liquid, the governing principles of desiccant dehumidification systems are the same. In the dehumidification process, the vapor pressure of the moist air is higher than that of the desiccant, leading to transfer of moisture from the air to the desiccant material. By heating the desiccant, the vapor pressure differential is reversed in the regeneration process that drives the moisture from the desiccant. Figure 1 illustrates a rotary solid-desiccant dehumidifier. A burner or a thermally compatible source of waste heat can provide the required heat for regeneration.

Download or read book An Assessment of Desiccant Cooling and Dehumidification Technology written by V. C. Mei and published by . This book was released on 1992 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Desiccant systems are heat-actuated cooling and dehumidification technology. With the recent advances in this technology, desiccant systems can now achieve a primary energy coefficient of performance (COP) between 1.3 and 1.5, with potential to go to 1.7 and higher. It is becoming one of the most promising alternatives to conventional cooling systems. Two important and well-known advantages of desiccant cooling systems are that they are CFC free and they can reduce the electricity peak load. Another important but lesser-known advantage of desiccant technology is its potential for energy conservation. The energy impact study in this report indicated that a possible 13% energy saving in residential cooling and 8% in commercial cooling is possible. Great energy saving potential also exists in the industrial sector if industrial waste heat can be used for desiccant regeneration. The latest study on desiccant-integrated building heating, ventilating, and air conditioning (HVAC) systems indicated that the initial cost for the conventional cooling equipment was greatly reduced by using desiccant technology because of downsized compressors, fans, and ductworks. This cost reduction was more than enough to offset the cost of desiccant equipment. Besides, the system operation cost was also reduced. All these indicate that desiccant systems are also cost effective. This study provides an updated state-of-the-art assessment forsiccant technology in the field of desiccant materials, systems, computer models, and theoretical analyses. From this information the technology options were derived and the future research and development needs were identified. Because desiccant technology has already been applied in the commercial building sector with very encouraging results, it is expected that future market breakthroughs will probably start in this sector. A market analysis for the commercial building application is therefore included.
