heating, cooling, dehumidification and filtering of air, but which does not include the source of heating or

cooling

Note 1 to entry: This device includes at least a liquid-to-air heat exchanger and a fan, and may be designed for

free or ducted intake air and/or for free or ducted delivery of supply air.
3.2
total electric power input

total electric power absorbed by the unit, including fan(s) and auxiliary devices but excluding any

electrical resistance heater
3.3
standard fan speed

fan speed setting declared by the manufacturer and used for setting the air flow rate conditions of ducted

units

Note 1 to entry: The fan speed setting can be declared by the manufacturer as a certain wiring, a switch position

or a steering voltage.
3.4

positive pressure difference measured between the air outlet and inlet sections of the unit

4 Measuring instruments

The acoustic instruments shall fulfil the requirements of the acoustic standard used for the test.

Other measurements can be necessary for the tests:
— Electrical: voltage (V), current (A), total electric power input (W);
— Pressure (Pa);
— Rotation speed (min ).

Measurements for the ambient conditions:
— Relative humidity (%);
— Air temperature (°C);
— Atmospheric pressure (kPa).
Table 1 gives the uncertainties allowed for these measurement values.

5 Operation of the unit
The testing conditions are given in EN 1397:2015 except the following:

— The acoustic test shall be performed without connection to water supply, without water staying in

the water circuit, with dry coil surface and an inlet air temperature between 15 °C and 25 °C.

— The control of the relative humidity is not required.

If the unit includes flaps, they shall be adjusted in a fixed position according to the manufacturer

instructions. If this information is not available, their position shall correspond to the maximum

mechanical open position.

NOTE 1 This maximum mechanical open position might differ from the minimum airflow resistance.

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 shall be closed.
NOTE 2 No modification such as sealing is made on the unit before testing.

For ducted units, an external static pressure difference of 50 Pa (±1 Pa) shall be applied to the unit for

the standard fan speed declared by the manufacturer.

If other speeds are tested, the same network curve resistance shall be used. See Figure 1.

If the resistance is obtained by using an auxiliary fan, preliminary tests shall be done to determine the

external static difference for each additional speed.

The unit shall be installed on the hard floor at a minimum of 1 500 mm away from any wall out of any

symmetry axis.
The feet provided by the manufacturer shall be used.

For aerodynamic purpose, the space between the feet shall be closed in the rear part to simulate the wall,

with a rigid and reflective plate, with the same width of the unit and not exceeding its height. See Figure 2.

For low-wall mounting units, the distance to the floor given by the manufacturer shall be respected.

Without information from the manufacturer, this distance shall be 150 mm.

For aerodynamic purpose, the space between the unit and the floor shall be closed in the rear part to
