  2. Duct leakage testing - Wikipedia

    en.wikipedia.org/wiki/Duct_leakage_testing

    Duct leakage test in the US. A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow.

  3. Blower door - Wikipedia

    en.wikipedia.org/wiki/Blower_door

    Duct leakage testing of forced air heating/cooling systems - both supply (vents) ducts and return ducts can be tested to determine if and how much they leak air. A duct test can be combined with a blower door test to measure the total leakage to outside, measuring effective leakage to the outside of the house only.

    Circulator Fan Facility capable of testing 96 inch fans. Acoustic Duct Silencer Facility; ISO/IEC 17025 accredited; AMCA International also oversees 40 accredited laboratories and two independent, accredited laboratories located in Taiwan and Singapore. Additional independent AMCA accredited laboratories are under construction in Korea and China.

  5. Ductwork airtightness - Wikipedia

    en.wikipedia.org/wiki/Ductwork_airtightness

    The relationship between pressure and leakage air flow rate is defined by the power law model between the airflow rate and the pressure difference across the ductwork envelope as follows: q L =C L ∆p n. where: q L is the volumetric leakage airflow rate expressed in L.s −1; C L is the air leakage coefficient expressed in L.s −1.Pa −n

  6. 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.

  7. HVAC control system - Wikipedia

    en.wikipedia.org/wiki/HVAC_control_system

    HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the ...

  8. Air Conditioning, Heating and Refrigeration Institute - Wikipedia

    en.wikipedia.org/wiki/Air_Conditioning,_Heating...

    The Air Conditioning, Heating, and Refrigeration Institute (AHRI), formed in 2008 by a merger of the Air-Conditioning and Refrigeration Institute (ARI) and the Gas Appliance Manufacturers Association (GAMA), is a North American trade association of manufacturers of air conditioning, heating, and commercial refrigeration equipment. [1]

  9. Duct (flow) - Wikipedia

    en.wikipedia.org/wiki/Duct_(flow)

    Sealing leaks in air ducts reduces air leakage, optimizes energy efficiency, and controls the entry of pollutants into the building. Before sealing ducts it is imperative to ensure the total external static pressure of the duct work, and if equipment will fall within the equipment manufacturer's specifications.
