Available in all digital devices Snapshot About The Book Refrigeration And Air Conditioning Book Summary: This textbook offers a comprehensive and wide-ranging introduction to theoretical principles and practical aspects of refrigeration and air conditioning systems. Written by an outstanding teacher with 30 years of distinguished career at the Indian Institute of Technology Kharagpur, this work created by late Dr. Arora is intended to lead students to a deeper understanding and a firm grasp of the basic principles of this fast-growing and exciting subject area. This text is ideally suited for undergraduate education in mechanical engineering programmes and specialized postgraduate education in thermosciences. The book is designed to typically appeal to those who like a more rigorous presentation. The text begins by reviewing, in a simple and precise manner, the physical principles of three pillars of Refrigeration and Air Conditioning, namely thermodynamics, heat transfer, and fluid mechanics. Following an overview of the history of refrigeration, subsequent chapters provide exhaustive coverage of the principles, applications and design of several types of refrigeration systems and their associated components such as compressors, condensers, evaporators, and expansion devices. Refrigerants too, are studied elaboratively in an exclusive chapter. The second part of the book, beginning with the historical background of air conditioning in Chapter 15, discusses the subject of psychrometrics being at the heart of understanding the design and implementation of air conditioning processes and systems, which are subsequently dealt with in Chapters 16 to It also explains the design practices followed for cooling and heating load calculations. Each chapter contains several worked-out examples that clarify the material discussed and illustrate the use of basic principles in engineering applications.

Some texts also cite acid, moisture and heat-caused sludge contamiantion in the system. Any condition that sends liquid refrigerant into the compressor motor can damage valves. We explain below that low head pressure at the compressor motor can in turn cause reduced lubrication in the motor and increased wear as well as permanent compressor damage.

An early sign of this wear may be reduced high side pressure and reduced cooling capacity of the system. An overheating compressor motor can in turn cause damage resulting in wear and low head pressures.

Refrigeration and Air Conditioning by Arora

On commercial systems and maybe some residential systems the reduced head pressure can cause refrigerant oil migration or more specifically, the system may be unable to push oil through the cooling coil the evaporator coil until it accumulates as a bolus of oil that suddenly returns in one shot tothe compressor.

The effects of poor oil return to the compressor include first reduced cooling capacity and later damage to the compressor motor. If the liquid line is not warm on your system you may face these problems. A-1 Compressors Smaller air conditioners or refrigeration equipment whose design does not include a refrigerant accumulator are at increased risk of damage from overcharge, liquid slugging, or oil circulation problems.

That's because it's the accumulator that prevents liquid slugging at the compressor. Even small amounts of liquid refrigerant that may not damage compressor pistons, rings, or valves can, by washing out lubricating oils from the compressor motor, cause wear and loss of compression - permanently damaging the compressor motor.

Patent 6,,, issued December 4, Excerpts from this patent description: An air conditioning servicing system utilizes a number of sensors which monitor various operating parameters of a malfunctioning air-conditioning system. These operating parameters are provided to a hand held computer along with an identifier of the malfunctioning air-conditioning system.

The hand held computer contains the normal operating parameters for a plurality of air-conditioning systems. Finally, they help designers avoid mistakes that could reduce the value of a skylight design.

The use of skylights continues to grow, both because they enliven building interiors and because they can save energy and money through daylighting.

Multi-Evaporator System

Skylighting skylights plus daylight controls can be a solid asset for almost any building, and help to satisfy human needs for building owners and occupants. When properly designed, skylights can make a number of major contributions to the built environment: Skylights provide high quality lighting conditions to building interiors Skylights reduce the use of electric lighting, to save energy and reduce peak electric loads, when combined with effective photosensor control systems Skylights provide visual and thermal comfort for building occupants Skylights increase safety and security with highly reliable daytime lighting Skylights provide emergency smoke vents DOWNLOAD NOW File-upload OR Media1fire OR Hulkload Email ThisBlogThis!
