2. Testing, adjusting, balancing - Wikipedia

   en.wikipedia.org/wiki/Testing,_adjusting,_balancing

   In heating, ventilation, and air conditioning (HVAC), testing, adjusting and balancing (TAB) are the three major steps used to achieve proper operation of heating, ventilation, and air conditioning systems. TAB usually refers to commercial building construction and the specialized contractors who employ personnel that perform this service.

   AMCA was formed in 1955 from several earlier trade associations which could be tracked back to the fan-testing requirements of the US Navy in 1923. It is a nonprofit organization that issues over 60 publications and standards, including testing methods, a Certified Ratings Program (CRP), application guides, educational texts, and safety guides.

   The HVAC industry was historically regulated by the manufacturers of HVAC equipment, but regulating and standards organizations such as HARDI (Heating, Air-conditioning and Refrigeration Distributors International), ASHRAE, SMACNA, ACCA (Air Conditioning Contractors of America), Uniform Mechanical Code, International Mechanical Code, and AMCA ...

7. Cooling load temperature difference calculation method

   en.wikipedia.org/wiki/Cooling_load_temperature...

   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 ...

8. Demand controlled ventilation - Wikipedia

   en.wikipedia.org/wiki/Demand_controlled_ventilation

   However, such spaces are not always fully occupied; in these cases, energy is wasted as the HVAC system processes more OA than is necessary for the space occupants. [3] Demand control ventilation is an attractive alternative to standard design in these situations because DCV systems only supply the outdoor airflow necessary to serve the ...

9. HVAC control system - Wikipedia

   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.
