Air Source Screw Water Chiller Unit – Installation Operation and Maintenance Manual
20
In areas where strong monsoon exists, if the unit's heat exchanger faces the direction from which the
monsoon comes, the air flow will occur when the monsoon wind velocity is higher than the fan blowing
velocity, as the dashed arrow shown in the following figure.
Monsoon
As a result, the cooled air flow will be cooled by another heat exchanger again. The refrigerating capacity
will reduce and the unit can be faulty. Although air-cooled screw water chiller units have been designed to
reduce the possibility of such circumstances, avoid installing the heat exchanger directly to the monsoon
direction during unit installation.
If the heat exchanger must be installed facing to the monsoon direction due to geological limitations, a
windbreak must be installed.
