If h<Hc→ L≥ 3,0 m (multi V) / L≥ 1,8 m (single V); if h>Hc or L is lower then recommended contact your Daikin distributor
to evaluate the various possible arrangements.
The minimum distances, reported above, ensure functionality of the chiller in most applications. However, there are specific
situations which include multiple chiller installation; in this case the following recommendations are to be followed:
Multiple chiller installed side by side in a free field with dominant wind
Considering an installation in areas with a dominant wind from a specific direction (as shown in the following fig.):
Chiller N°1: is performing normally without any ambient over-temperature
Chiller N° 2: is working in a warmed ambient. The chiller is working with air recirculating from Chiller 1 and and
recirculation from itself.
Chiller N° 3: is working in an over-temperature ambient due to the recirculating air from the other two chillers.
In order to avoid the hot air recirculation due to dominant winds, the installation where all chillers are aligned to the dominant
wind is preferred (see figure below).
Multiple chiller installed side by side in a compound
In case of compounds with walls of the same height of the chillers or higher, the installation is not recommended. Chiller 2
and chiller 3 work with sensible higher temperature due to the enhanced recirculation. In this case special precautions
must be taken in to account according to the specific installation (eg: louvered walls, install the unit on base frame in order
to increase the height, ducts on the discharge of the fans, high lift fans, etc).
All the above cases are even more sensitive in case of design conditions close to the limits of the unit operating envelope.
NOTE: Daikin cannot be considered responsible in case of malfunctions generated by hot air recirculation or insufficient
airflow as result of improper installation if the above recommendations are ignored.
