Book excerpt: I have done HVAC projects for 30 years and know what are the most important points to cover. In today’s fast-paced lives, time is a precious entity. Therefore reading long lines of text in a book or article can become a lethargic task. But Reading a short book with helpful context delivering the same meaning helps save a lot of time. Nowadays, people do not have much time for long books or long videos. That is why we are seeing the popularity of sites like Blinkist who made a resume of 4000 famous books into 15 minute reads with concise key points that the reader should know. Also if you check the popularity of short videos on tikTok and now followed by you tube shorts. With my 30 years of HVAC experience I have decided to compile the knowledge into a very concise book. Hope you enjoy reading and you gain much experience of this book.

Download or read book HVAC Chilled Water Distribution Schemes written by Anuj Bhatia and published by CreateSpace. This book was released on 2015-02-25 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: In large commercial and industrial systems, chilled water system serves as means to transfer heat from building spaces to the refrigeration system. Initially, when energy costs were low, constant volume and primary-secondary systems provided a stable and simple operation of the chillers and distribution systems. However, as energy costs increased, particularly in the late 1970s, the efficiency of the chillers and the costs associated with operating the distribution system became more important. As a result, the need for new schemes to improve chiller performance and reduce energy costs drove the HVAC industry to advance chilled water technology, particularly in the manner that chilled water is delivered. To understand the hydraulic considerations associated with delivering chilled water and how they influence system performance, it is important to understand how technology and design challenges over the years have influenced today's approach to chilled water pumping. This 5 - hour Quick Book discusses the history of chilled water distribution systems and the development of “variable primary flow system”. Problems such as low delta-T syndrome associated with the chilled water pumping schemes are defined and discussed and finally, this course compares the advantages and disadvantages of primary-secondary and direct-primary pumping schemes. Three chilled water schemes are discussed:SCHEME -1: CONSTANT FLOW CHILLED WATER SYSTEM SCHEME -2: PRIMARY / SECONDAY DISTRIBUTION SCHEMESCHEME -3: VARIABLE PRIMARY FLOW SCHEMEThe course includes a multiple-choice quiz consisting of twenty five (25) questions at the end to enhance course learning. Learning ObjectiveAt the conclusion of this course, the student will able to understand:1. The basic hydronic principles i.e. relationship of chilled water flow rate v/s cooling load and the energy savings due to adjustable speed pumps. 2. How do constant volume chilled water systems different from primary/secondary arrangement?3. What is low delta-T syndrome and how it affects the chiller loading?4. What are the causes and mitigation measures to prevent low delta-T syndrome?5. Why distributed pumping arrangement is better than headered arrangement for constant flow systems?6. How do primary/secondary chilled water systems create hydraulically independent loops?7. How to size the de-coupler bridge?8. The characteristics of control valves and why 2-way valve is better than 3-way valve in variable flow systems?9. How do the variable primary flow system compare with primary/secondary system in terms of cost and energy?10. The importance of design tube velocity and rate of chilled water flow variations in variable primary flow systems.

Download or read book Aging Assessment of Essential HVAC Chillers Used in Nuclear Power Plants Phase 1 written by and published by . This book was released on 1993 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Pacific Northwest Laboratory conducted a Phase I aging assessment of chillers used in the essential safety air-conditioning systems of nuclear power plants. Centrifugal chillers in the 75- to 750-ton refrigeration capacity range are the predominant type used. The chillers used, and air-conditioning systems served, vary in design from plant-to-plant. It is crucial to keep chiller internals very clean and to prevent the leakage of water, air, and other contaminants into the refrigerant containment system. Periodic operation on a weekly or monthly basis is necessary to remove moisture and noncondensable gases that gradually build up inside the chiller. This is especially desirable if a chiller is required to operate only as an emergency standby unit. The primary stressors and aging mechanisms that affect chillers include vibration, excessive temperatures and pressures, thermal cycling, chemical attack, and poor quality cooling water. Aging is accelerated by moisture, non-condensable gases (e.g., air), dirt, and other contamination within the refrigerant containment system, excessive start/stop cycling, and operating below the rated capacity. Aging is also accelerated by corrosion and fouling of the condenser and evaporator tubes. The principal cause of chiller failures is lack of adequate monitoring. Lack of performing scheduled maintenance and human errors also contribute to failures.

Download or read book Heat Rejection Options in HVAC Systems written by A. Bhatia and published by Createspace Independent Publishing Platform. This book was released on 2014-12-05 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the basic requirements of the air conditioning and refrigeration system is to reject heat to the outdoors. The refrigerant chillers come in two different forms: -An air-cooled chiller uses the flow of outside air across the condenser to remove or reject heat from the chiller. Air-cooled chillers typically have the condenser mounted on the roof or somewhere outside the facility while the evaporator can either be inside or outside the facility. -Water-cooled chillers are typically 100 tons or greater and use water to remove the heat from the condenser. Water-cooled chillers are typically more efficient than air-cooled chillers. The condenser water is kept cool by a cooling tower, or water from the city main or well water is used. A water-cooled chiller will typically have the condenser and evaporator inside a facility while the cooling tower is located outside. In order to properly apply the heat rejection concepts, HVAC designer must be aware of the different heat rejection methods. In this course we will discuss the various heat rejection methods as well the controls that may be used to maintain proper refrigerant and water temperatures. Also presented in the course is the concept of total heat of rejection, its derivation and how it applies to the process of air conditioning. This 4-hour quick book provides a comprehensive description of the five prominent heat rejection methods as applicable to air conditioning systems. This course is applicable to architects, air-conditioning engineers, controls engineers, contractors, environmentalists, energy auditors and loss prevention professionals. It is assumed that all the readers know the basic functioning of the air-conditioning system. Learning Objective This course is intended to provide you with the following specific knowledge and skills: -The concept of total heat of rejection (THR), its derivation and how it applies to the process of air conditioning; -Five prominent methods of heat rejection; -Importance of sub-cooling and super-heat in air-cooled condensers; -Types, rating and selection of air cooled condensers; -Operating principle of wet cooling towers; -Types of cooling towers, cross-flow, counter-flow, induced draft and forced draft; -Capacity control of air cooled and water cooled systems; -Closed circuit fluid coolers v/s evaporative condensers; -Energy performance of air-cooled chiller v/s water cooled systems; -Effectiveness of adiabatic cooling technology; -Benefits and limitations of various heat rejection methods; -The selection of appropriate method on capital costs and environment criteria.
