ASHRAE's Handbook Committee maintains an Authors and Revisers Guide, which can be obtained freely via the Handbook portion of the ASHRAE Web site. While each new or revised chapter manuscript is to be reviewed for technical content by each TC voting and corresponding member before publication, there are often many other pre- and post ...
The CLTD/CLF/SCL (cooling load temperature difference/cooling load factor/solar cooling load factor) cooling load calculation method was first introduced in the 1979 ASHRAE Cooling and Heating Load Manual (GRP-158) [1] The CLTD/CLF/SCL Method is regarded as a reasonably accurate approximation of the total heat gains through a building envelope ...
DOAS air handling unit with heat recovery wheel and passive dehumidification. A dedicated outdoor air system (DOAS) is a type of heating, ventilation and air-conditioning system that consists of two parallel systems: a dedicated system for delivering outdoor air ventilation that handles both the latent and sensible loads of conditioning the ventilation air, and a parallel system to handle the ...
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.
HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers).
Free Air Conditioners for people 65 and older. If you or someone you know is 65 years or older and in need of an air conditioner, the Bishop Sullivan Center’s Project ElderCool can also be ...
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 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.
