42、let air flow rate is optional for free delivery units and for ducted units with a declared external static pressure lower than 50 Pa at standard fan speed. For testing, the unit shall include an air filter but no any other accessory for air inlet or diffusion or others. Dampers for fresh air intake
43、shall be closed. NOTE 1 No modification such as sealing is made on the unit before testing. NOTE 2 This maximum mechanical open position might differ from the minimum airflow resistance. If the unit includes flaps, they shall be adjusted in a fixed position according to the manufacturer instructions
44、. If this information is not available, their position shall correspond to the maximum mechanical open position, B.2 Testing equipment The air flow measurement equipment consists of a test chamber, an air flow measuring device and an auxiliary fan, all in accordance with ISO 5801. An auxiliary fan s
45、hall be used to control the external static pressure at the fan coil outlet. It shall be designed to overcome pressure losses through the test setup, and equipped with adjustment means such as dampers, pitch control, or speed control to vary the capacity. B.3 Test installation The discharge section
46、of the fan coil unit shall be connected to an air flow measuring device as described in ISO 5801, through a ductwork. In case of several outlet sections, they shall discharge in a common plenum.
