Study guide from Permacharts. Academic support centers in schools often develop study guides for their students, as do for-profit companies and individual students and professors. Once only found at local five and dime stores the internet brought about a new era of online sites with study material.
ASHRAE was founded in 1894 at a meeting of engineers in New York City, formerly headquartered at 345 East 47th Street, and has held an annual meeting since 1895. [4] Until 1954 it was known as the American Society of Heating and Ventilating Engineers (ASHVE); in that year it changed its name to the American Society of Heating and Air-Conditioning Engineers (ASHAE).

The International Mechanical Code (IMC) is a convention concentrating on the safety of heating, ventilation, and air conditioning systems. It is published by the International Code Council (ICC) through the governmental consensus process and is updated on a three-year cycle to include the latest advances in technology and safest mechanical practices.
The Uniform Mechanical Code (UMC) is a model code developed by the International Association of Plumbing and Mechanical Officials to govern the installation, inspection and maintenance of HVAC (heating, ventilating and air-conditioning) and refrigeration systems. It is designated as an American National Standard.
To reduce draft risk at temperatures below 22.5 °C (72.5 °F), air speed due to the HVAC system must be 0.15 m/s (30 ft/min) or below. The vertical air temperature difference between ankle and head is limited to 3 °C (5.4 °F) for seated occupants and 4 °C (7.2 °F) for standing occupants. [6]

However, when designing HVAC systems, many engineers design it for a specific setting and/or purpose. When engineers are designing an HVAC system, they try their best to make it compact while still being able to perform at the highest level and experiment with different ways to make HVAC systems as efficient as possible.
