Successful Heating, Ventilating, and Air Conditioning (HVAC) systems are the key to successful buildings. Because each building is different, it is very important to choose a system that is right for the facility. Proper selection of the HVAC system is a crucial decision for any new project and the decision depends upon a number of factors like how large area needs to be cooled, what is the application, what kind of total heat is generated inside the enclosed area, the developer's preference - initial installation cost, aesthetics, and long term maintenance and life cycle costs etc etc. The HVAC engineer would consider all the related parameters and suggest the system most suitable for your space. Many different HVAC systems are available today but the design and selection of right HVAC system must combine a proper choice of engineered products efficiently providing conditioned air to the space at optimum energy while adding architectural features which complement the interior design. This 5 -hour course discusses the various issues to be considered and the questions to be raised before an intelligent, well-thought HVAC scheme is finalized. The distinction between 'central' and local floor-by-floor 'compact' systems is critical from an architectural perspective and shall serve the primary theme for this course. The course is intended for use primarily to the architects, engineers, contractors, facility managers, O&M personnel and HVAC designers. Learning ObjectiveAt the conclusion of this course, the student will: * Understand the different types of HVAC systems;* Understand the HVAC design challenges on various architectural and functional parameters;* Understand the difference between central and decentralized systems;* Understand the central chilled water system sub-configurations;* Understand various types of decentralized systems (window, split, package, heat pumps and VRF systems);* Understand the pros and cons of the central and compact systems;* Understand how to select the right system for your application.

Commercial air conditioning may be provided by a variety of equipment ranging from low horsepower self-contained systems to the very large built-up central systems of several thousand ton capacity. Customer/user's ultimate objective is to acquire and utilize an air conditioning system that will provide the most appropriate performance on a whole of life basis, in terms of capital, operating, replacement and maintenance costs. It's the architect's/HVAC engineer's responsibility to guide and advise the customers the best option. HVAC systems are of great importance to architectural design efforts for four main reasons. 1. First, the success or failure of thermal comfort efforts is usually directly related to the success or failure of a building's heating, ventilation and air conditioning (HVAC) systems;2. Second, HVAC systems often require substantial floor space and/or building volume for equipment and distribution elements that must be accommodated during the design process; 3. Third, HVAC systems require significant capital investments; 4. Last, but not least, the HVAC system is responsible for large portion of building operating costs. The design and selection of right HVAC system therefore must combine a proper choice of engineered products efficiently providing conditioned air to the space at optimum energy while adding architectural features that shall complement the interior design. This 5 - hr Quick Book course discusses the various issues to be considered and the questions to be raised before an intelligent, well-thought HVAC scheme is finalized. The advantages and disadvantages, which arise as a result of centralized or decentralized air conditioning systems, are evaluated in this course.The course is intended for use primarily to the architects, engineers, contractors, facility managers, O&M personnel and HVAC designers. Learning ObjectiveAt the conclusion of this course, the student will: * Understand the different types of HVAC systems;* Understand the HVAC design challenges on various architectural and functional parameters;* Understand the difference between central and decentralized systems;* Understand the central chilled water system sub-configurations;* Understand various types of decentralized systems (window, split, package, heat pumps and VRF systems);* Understand the pros and cons of the central and compact systems;* Understand how to select the right system for your application.

In this book, various aspects of heating, ventilation, and air-conditioning (HVAC) systems are investigated. HVAC systems are milestones of building mechanical systems that provide thermal comfort for occupants accompanied with indoor air quality. HVAC systems can be classified into central and local systems according to multiple zones, location, and distribution. Primary HVAC equipment includes heating equipment, ventilation equipment, and cooling or air-conditioning equipment. Central HVAC systems are located away from buildings in a central equipment room and deliver the conditioned air by a delivery ductwork system. Central HVAC systems contain all-air, air-water, or all-water systems. Two systems should be considered as central such as heating and cooling panels and water-source heat pumps.

The Air Conditioning Manual assists entry-level engineers in the design of air-conditioning systems. It is also usable - in conjunction with fundamental HVAC&R resource material - as a senior- or graduate-level text for a university course in HVAC system design. The manual was written to fill the void between theory and practice - to bridge the gap between real-world design practices and the theoretical calculations and analytical procedures or on the design of components. This second edition represents an update and revision of the manual. It now features the use of SI units throughout, updated references and the editing of many illustrations. * Helps engineers quickly come up with a design solution to a required air conditioning system. * Includes issues from comfort to cooling load calculations. * New sections on "Green HVAC" systems deal with hot topic of sustainable buildings.

As Humans’ need for comfort living takes priority, Heating, Ventilation and Air Conditioning systems (HVAC)would assume more importance and priority – The number and percentage of people opting, creating and living in conditioned spaces might also serve as an index for living standards. In my search for understanding the different types of styles and configurations of HVAC systems - I finally realized that I could understand the different executions only if I work with a HVAC company. This somehow materialized – I started working for Superior air- a HVAC subcontractor engaged in providing, installing HVAC systems in San Diego City in California. My learning started with studying their installations, visiting job sites and looking at construction and approved drawings. I also had the opportunity to interact with construction supervisors, experts in HVAC systems, and construction workers. The installations I visited are mostly in commercial / office buildings and involved almost all the types mentioned in the book. To facilitate ease of understanding, the book includes maximum possible images of the systems/ lay outs. I will be extremely thankful to the readers if they could give me feedback comments and any other information/images that can be included for regular updates.
