This book was released on 2013-11-19 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing concern with indoor air quality has led to air-quality standards with increased ventilation rates. Although increasing the volume flow rate of outside air is advisable from the perspective of air-quality, it is detrimental to energy consumption, since the outside air has to be brought to the comfort condition before it is insufflated to the conditioned ambient. Moreover, the humidity load carried within outside air has challenging HVAC engineers to design cooling units which are able to satisfactorily handle both sensible and latent contributions to the thermal load. This constitutes a favorable scenario for the use of solid desiccants to assist the cooling units. In fact, desiccant wheels have been increasingly applied by HVAC designers, allowing distinct processes for the air cooling and dehumidification. In fact, the ability of solid desiccants in moisture removal is effective enough to allow the use of evaporative coolers, in opposition to the traditional vapor-compression cycle, resulting in an ecologically sound system which uses only water as the refrigerant. Desiccant Assisted Cooling: Fundamentals and Applications presents different approaches to the mathematical modeling and simulation of desiccant wheels, as well as applications in thermal comfort and humidity controlled environments. Experts in the field discuss topics from enthalpy, lumped models for heat and mass transfer, and desiccant assisted radiant cooling systems, among others. Aimed at air-conditioning engineers and thermal engineering researchers, this book can also be used by graduate level students and lecturers in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Air conditioning system is one of the major consumers of electrical energy in many parts of the world today. It represents between 40 and 70% of the energy consumption in commercial buildings. The demand of energy for air conditioning systems is expected to increase further in the next decades due to the population growth, the new economic boom, and the urbanization development. The rapid growth of air conditioning and electricity consumption will contribute further to climate change if fossil and nonrenewable resources are used. More energy-efficient and renewable energy-based air conditioning systems to accomplish space cooling are needed. This book intends to provide the reader with a comprehensive overview of the current state of the art in sustainable air conditioning technologies and focus on the most recent research and development on green air conditioning systems including energy-efficient and renewable energy-based air conditioning systems.

Book excerpt: The present invention provides an apparatus for dehumidifying air supplied to an enclosed space by an air conditioning unit. The apparatus includes a partition separating the interior of the housing into a supply portion and a regeneration portion. The supply portion has an inlet for receiving supply air from the air conditioning unit and an outlet for supplying air to the enclosed space. A regeneration fan creates the regeneration air stream. The apparatus includes an active desiccant wheel positioned such that a portion of the wheel extends into the supply portion and a portion of the wheel extends into the regeneration portion, so that the wheel can rotate through the supply air stream and the regeneration air stream to dehumidify the supply air stream. A heater warms the regeneration air stream as necessary to regenerate the desiccant wheel. The invention also comprises a hybrid system that combines air conditioning and dehumidifying components into a single integrated unit.

This book was released on 1999-10-01 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rotary desiccant wheels are commonly used for industrial dehumidification systems and significant research has also been done to increase their application in other HVAC systems. The transient response is of concern because it can affect system overall performance and previous research efforts have indicated the transient response to be of substantial duration. This research experimentally and analytically investigated the transient response of rotary desiccant wheels. A model was developed to predict the transient response of rotary desiccant wheels with significant improvements to previous versions. The basic model uses fundamental principles of heat and mass transfer with the finite difference method. The parabolic concentration profile was used to approximate moisture gradients within the desiccant particle. This concept is fundamentally more correct than previous lumped capacitance models and avoids the computational difficulties of more rigorous models which include an extra second order differential equation. The NTU terms from the finite difference equations were also calculated at each point rather than as constants for a stream or wedge since they are significantly temperature and moisture dependent. The numerical solution techniques improved the speed and flexibility of the model by using a tri-diagonally banded matrix solver for the difference equations and the bisection method was used for the parabolic concentration profile. Experimental work was performed at the National Renewable Energy Laboratory (NREL) in Golden, CO on a commercially available rotary desiccant wheel made by NovelAire. Step changes to regeneration temperature, wheel speed, and flowrate were performed. The model validated very well using the experimental data through statistical and visual analysis of the outlet condition (temperature, humidity ratio) response curves.
