Book Description
Introduction to Air Handling Units (AHUs) An Air Handling Unit (AHU) is a critical component in heating, ventilation, and air conditioning (HVAC) systems. These units are used to regulate and circulate air as part of a heating, ventilating, and air-conditioning system. Components of an AHU Blower/Fan: Moves air through the AHU and ductwork. Heating/Cooling Coils: Heat exchangers that transfer heat to or from the air passing through them. Filters: Remove particles and contaminants from the air. Humidifiers/Dehumidifiers: Control the humidity level in the air. Mixing Box: Combines return air with fresh air. Dampers: Control the flow of air within the system. Control Systems: Include sensors, thermostats, and controllers to regulate temperature, humidity, and airflow. Types of AHUs Draw-Through AHUs: The fan is located after the air-handling components (such as coils and filters), drawing air through them. Blow-Through AHUs: The fan is located before the air-handling components, blowing air through them. Functionality Ventilation: AHUs bring in fresh air from outside and expel stale air from inside, ensuring indoor air quality. Temperature Control: By heating or cooling the air, AHUs maintain desired indoor temperatures. Humidity Control: Adding or removing moisture from the air to maintain comfortable humidity levels. Air Filtration: Removing dust, pollen, and other airborne particles to improve air quality. Applications Commercial Buildings: Offices, shopping malls, hospitals, and schools where maintaining a comfortable and healthy indoor environment is crucial. Industrial Settings: Factories and laboratories that require precise environmental control to ensure product quality and safety. Residential Buildings: High-end homes and apartment complexes that need advanced climate control and air quality management. Benefits Energy Efficiency: Modern AHUs are designed to be energy-efficient, reducing operational costs. Comfort: Maintain consistent and comfortable indoor environments. Health: Improve indoor air quality by filtering pollutants and controlling humidity, which can reduce the prevalence of mold and allergens. Flexibility: Can be customized to meet the specific requirements of different buildings and applications. Maintenance Regular maintenance is essential for the efficient operation of AHUs. This includes: Filter Replacement: To ensure air quality and system efficiency. Coil Cleaning: To maintain heat exchange efficiency. Fan Maintenance: To prevent mechanical failures and ensure proper airflow. Checking Control Systems: To ensure they are operating correctly and responding to environmental changes. Conclusion Air Handling Units are vital for creating and maintaining comfortable, healthy, and efficient indoor environments in a variety of settings. Understanding their components, functionality, and maintenance requirements can help optimize their performance and extend their lifespan.

Book Description
Sustainability of environment is an emerging global issue at present. Unsustainable or deteriorating environment is a matter of concern as it has threatened the survival of living creatures. Recently, climate change has been a matter of great concern at a global platform owing to imbalances in natural environment. Increasing population has increased the demand for energy, which has ultimately put pressure on natural resources and caused a paradigm shift from resource generation to exploitation. Emerging Energy Alternatives for Sustainable Environment aims to address the role of sustainable technologies in energy generation options for clean environment. It covers a wide spectrum of energy generation approaches, with an emphasis on five key topics: (i) renewable energy sources and recent advances, (ii) emerging green technologies for sustainable development, (iii) assessment of biomass for sustainable bioenergy production, (iv) solid waste management and its potential for energy generation, and (v) solar energy applications, storage system, and heat transfer. This book provides essential and comprehensive knowledge of green energy technologies with different aspects for engineers, technocrats and researchers working in the industry, universities, and research institutions. The book is also very useful for undergraduate and graduate students of science and engineering who are keen to know about the development of renewable energy products and their corresponding processes.
