6.2 Requirements of arrangement space of the unit
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.
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
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 smoothy.
