HVAC components may be designed for ceiling, wall or floor mounting, and for use in supply or exhaust air applications. Grille, diffuser, and other HVAC component testing Closed-blade air leakage tests (at high temperatures).Closed-blade air leakage tests (ambient air).Testing can be undertaken in accordance with Singapore standards, UL, AMCA, BS, ISO, and Australian standards. Vipac's Air Distribution & Acoustic Laboratory provides a highly specialised facility for the design, development, and performance testing of all types of dampers (such as fire / smoke dampers, pressure relief dampers, VCD and NRD). To develop and verify dampers to an adequate standard, extensive performance testing is required. Quality dampers minimise property damage and save lives as they’re a crucial element of preventing the spread of fire and smoke. Smoke and fire dampers in action Damper testing Duct (silencer), including general domestic ventilation, cooling / heating, and industrial useįor further information, please click on one of the below areas of testing.VAV (variable air volume) terminals (singular and multiple outlets).Grille, diffusers, and other HVAC component testing.Louvres and vents (design, development, and performance testing).Fans (design, development, and performance testing).Water penetration, discharge coefficient, and wind load testing of weather louvres.Silencer insertion loss (static and dynamic).Measurements of flow, pressure drop and throw.Leakage testing of smoke and fire dampers.Sound testing (sound power determination).Air diffusion (10☌ to 45☌) and occupant comfort testing (ADPI, PMV and PPD).Testing to ASHRAE, ARI, ADC, AMCA, ISO, BSI, and Australian standards.Conforming to ISO 3741, it’s also connected to a second reverberation chamber (5.2 m x 5.2 m x 5.2 m), allowing for the testing of insertion and transmission loss. Air can be supplied at temperatures between 7☌ and 50☌ for non-isothermal testing. ![]() With a “quiet air supply,” the lab can produce measured flow rates from 10L/s to 3.500 L/s, at static pressure up to 1kPa. ![]() Flow visualisation and video recording of smoke patterns can also be readily undertaken. It’s large enough to allow airflow patterns to be modelled in three-dimensional space. Our Air Distribution & Acoustic Laboratory, measuring 9 m x 4.2 m, can be used to conduct full-scale mock-ups of various Heating, Ventilation and Air-Conditioning (HVAC) systems. This ensures our acoustic test chambers are independently audited, and that international best quality practices are followed. ![]() Vipac’s labs are NATA accredited to ISO/IEC 17025 and the quality system is certified to AS/NZS ISO 9001:2015 by BSI.
