Book Description
"This manual focuses on the calculation of cooling and heating loads for commercial buildings. The heat balance method (HBM) and radiant time series method (RTSM) (as well as how to implement these methods) are discussed. Heat transfer processes and their analysis, psychrometrics, and heating load calculations are also considered"--

Book Description
Heating and cooling load calculations are carried out to estimate the required capacity of heating and cooling systems, which can maintain the required conditions in the conditioned space. To estimate the required cooling or heating capacities, one has to have information regarding the design indoor and outdoor conditions, specifications of the building, specifications of the conditioned space (such as the occupancy, activity level, various appliances and equipment used etc.) and any special requirements of the particular application. For comfort applications, the required indoor conditions are fixed by the criterion of thermal comfort, while for industrial or commercial applications the required indoor conditions are fixed by the particular processes being performed or the products being stored. Generally, heating and cooling load calculations involve a systematic and stepwise procedure, which account for all the building energy flows. In practice, a variety of methods ranging from simple rules-of-thumb to complex transfer function methods are used to arrive at the building loads. This short quick book provides a procedure for preparing a manual calculation for cooling load using CLTD/CLF method suggested by ASHRAE and includes two detailed examples. For more advanced methods such as TFM, the reader should refer to ASHRAE and other handbooks.Learning ObjectiveAt the end of this course, the student should be able to: 1. Understand the basic terminology and definitions related to air conditioning load calculations 2. Explain the differences between heating and cooling load design considerations3. Explain the difference between 1) space heat gain v/s cooling load 2) space cooling v/s cooling load and 3) external loads v/s internal loads4. Differentiate between sensible and latent loads5. List commonly used methods for estimating cooling loads 6. Estimate the internal and external cooling loads using CLTD/CLF method from building specifications, design indoor and outdoor conditions, occupancy etc. 7. Describe various equations and the information sources to determine conductive load through opaque building elements.8. Describe various equations and information sources to determine the solar transmission load through glazing.9. Describe various equations and information sources to determine the internal load due to people, lights and power appliances.10. Determine the supply air flow rate11. Learn by examples the detailed methodology to cooling load calculations12. Learn the functional parameters of software programs such as TRACE 700 and CHVAC

Book Description
Heating Ventilation and Air Conditioning by J. W. Mitchell and J. E. Braun provides foundational knowledge for the behavior and analysis of HVAC systems and related devices. The emphasis of this text is on the application of engineering principles that features tight integration of physical descriptions with a software program that allows performance to be directly calculated, with results that provide insight into actual behavior. Furthermore, the text offers more examples, end-of-chapter problems, and design projects that represent situations an engineer might face in practice and are selected to illustrate the complex and integrated nature of an HVAC system or piece of equipment.

Book Description
Heating, Ventilation and Air-Conditioning (HVAC)systems are omnipresent in modern buildings. This book is an introduction to all those involved in the specification, design, manufacture, installation, operation or maintainance of these systems. The book explains: • The objectives to be achieved by a system in terms of environmental control. • The description of a system - including primary equipment, means of distribution, space and load determination, and operating strategy. • The basic function of components that form HVAC systems. • The layout and functioning of common HVAC systems, including all-air systems, air-water systems, and all-water systems. • The strategies for operating systems and their basic means of control. • Identifying the most suitable type of system for different types of application. * Air-conditioning is a major growth industry, this introduction to how systems operate and how to select, design and operate them effectively * Endorsed by, and developed with ASHRAE, the leading trade body and recognised technical experts * Provides a thorough introduction to how HVAC systems function in controlling temperature, air quality, and air circulation in a controlled space.

Book Description
Updated with chapters on ventilating and exhausting systems and HVAC systems, this third edition of a bestseller covers the range of HVAC systems. The coverages is into components and controls for air, water, heating, ventilating, and air conditioning and readers will learn why one component or system may be chosen over another. This master volume covers the full range of HVAC systems used in today's facilities. Comprehensive in scope, the text is intended to provide the reader with a clear understanding of how HVAC systems operate, as well as how to select the right system and system components to achieve optimum performance and efficiency for a particular application. You'll learn the specific ways in which each system, subsystem or component contributes to providing the desired indoor environment, as well as what factors have an impact on energy conservation, indoor air quality and cost. Examined in detail are compressors, water chillers, fans and fan drives, air distribution and variable air volume, pumps and water distribution, controls and their components, heat recovery, and energy conservation strategies. Also covered are heat flow fundamentals, as well as heat flow calculations used in selecting equipment and determining system operating performance and costs.
