27、be designed in such a way that all requirements on adjustment of set values, stabiiity criteria and uncertainties of measurement according to this European Standard can be fulfilled. Ducted air systems shall be sufficiently air tight to ensure that the measured results are not significantly infiuenc
28、ed by exchanges of air with the surroundings. 4.2.1.2 Test room fw the airside The size of the test room shall be selected such that any resistance to air flow at the air inlet and air outlet orifices of the test object is avoided The air flow through the room shall not be capable of initiating any
29、short circuit between these two orifices and therefore the velocity of the air flows through the room at these two locations shall not exceed 1,5 m/s when the test object is switched off. The air velocity in the room shall also not be greater than the mean velocity through the unit inlet. Uniess oth
30、erwise stated by the manufacturer, the air inlet and outlet orinces shall not be less than 1 m distant from the surfaces of the test room; this also applies to any measuring ducts. Any direct heat radiation by heating devices in the test room onto the unit or onto the temperature measuring points sh
31、ail be avoided. 4.2.1.3 Setting the tmkrnal static pressure dgfme on the air side for appliances with duct conmtion For appliances with duct connection, the maximum external pressure difference available at the nominal flow raie specified by the manufacturer is preferably set on the air outlet side
32、of the unit when the rehgerating system does not operate.

33、available at the nominal flow rate specified by the manufacturer is preferably set on the outlet side of the unit, this also sets the water flows.
