3.3 Requirements of arrangement space of the unit
3.3.1 Requirements of arrangement space of the unit
3.3.1.1 To ensure adequate airflow entering the
condenser, the influence of descending airflow caused by
the high-rise buildings around upon the unit should be
taken into account when installing the unit.
3.3.1.2 If the unit is installed where the flowing speed of
air is high, such as on the exposed roof, the measures
including sunk fence and Persian blinds can be taken, to
prevent the turbulent flow from disturbing the air entering
the unit. If the unit needs to be provided with sunk fence,
the height of the latter should not be more than that of
the former; if Persian blinds are required, the total loss of
static pressure should be less than the static pressure
outside the fan. The space between the unit and sunk
fence or Persian blinds should also meet the requirement
of the minimum installation space of the unit.
3.3.1.3 If the unit needs to operate in winter, and the
installation site may be covered by snow, the unit should
be located higher than the snow surface, to ensure that
air flows through the coils smoothly.

NOTE
After installing the spring damper, the total height of the unit will
increase by 135mm or so.
The ports of inlet and outlet pipes should be flange ports, and
flanges should be hubbed slip-on-welding steel pipe flanges.
