Air Conditioning Load Calculation


Air Conditioning Load Calculation

air conditioning load calculation

    air conditioning

  • A system for controlling the humidity, ventilation, and temperature in a building or vehicle, typically to maintain a cool atmosphere in warm conditions
  • air conditioner: a system that keeps air cool and dry
  • (Air-conditioned) buses fares cost a little over four times the fare of an ‘Ordinary’ route covering the same distance. Those buses have route numbers starting with A.
  • A system which can generate both temperature controlled cold and warm air via a fan.

    load calculation

  • A load calculation is performed by HVAC professionals to determine the proper size cooling and heating system for your home. It considers factors such as the size of your house, the number of windows and the area’s year-round weather. An accurate estimate is required for optimal performance.
  • A mathematical determination of how much cooling and heating (BTUs) an HVAC system must deliver for occupant safety and comfort.
  • Assessed by a dealer, the calculation factors in a number of criteria in your home (square footage, number of windows, year-round weather concerns) and determines what size components you should include as part of your total comfort system.

air conditioning load calculation – Air Handling

Air Handling Systems Design
Air Handling Systems Design
Designing an air handling system can be a challenging task given the vast arrary of systems options from which to choose. In this highly practical reference, HVAC engineers will find all the information and guidance they need to select the most cost-effective, energy-efficient system to satisfy the design requirements of a specific project. The only book available that focuses exclusively on central air handling systems, this comprehensive book explores the full range of designs for systems commonly in use today in all types of buildings. The author provides detailed information on more than 25 constant volumes, variable volume, and hybrid systems – including single zone, terminal reheat, double duct, dual conduit, and hydronic heat pump systems. In addition, the book fully examines the differences between various system types, evaluates the advantages and disadvantages of each system, reviews basic heating and cooling loads and load variations, discusses the importance of psychrometrics in system design and selection, and outlines techniques for energy conservation and system retrofitting. Of special interest are the many diagrams that clearly illustrate all types of air handling system designs.

Manual N - Commercial Load Calculation
The new fifth edition of Manual N, from the Air Conditioning Contractors of America (ACCA), details the correct HVAC load calculation procedure for small and mid-size commercial buildings. This new edition addresses advances in the commercial construction industry, such as new materials, methods of assembly, and operational requirements. It provides instruction to help contractors and designers satisfy new (and often conflicting) energy, ventilation, and comfort requirements. Manual N is divided into four sections providing both a quick procedure, and a more comprehensive procedure, based on the requirements of your application.
