Method for testing air leakage in junction boxes
This method applies air pressure to the test object (workpiece), then measures the change in internal pressure to determine leaks. Air leak testing is a common method used by manufacturers. 1 Air leakage between an air distribution system and unconditioned spaces affects the energy losses from the distribution system, the ventilation rate of the building, and the entry rate of air pollutants. 2 The determination of infiltration energy loads and ventilation rates of residences and. Building America-funded research by teams and national laboratories resulted in the development of an ASHRAE standard and a standardized testing method for testing the air leakage of HVAC air handlers and furnace cabinets and has spurred equipment manufacturers to tighten the cabinets they use for. The purpose of this procedure is to document the requirements for field air leak testing of Air Handling Systems Solution and Custom equipment manufactured by Johnson Controls. It is recommended that a custom Factory Leak Test Fan or equivalent is used for leakage testing.
