+7/+12 Fan Air Handling Unit

 

The air handling unit is generally designed to exchange heat with the water (+7/+12) it receives from the cold water producer (chiller) through the fan coil. The power plant can directly absorb and cool hot air, or it can transfer water from the power plant and cool and heat the areas where necessary. The +7/+12 range is generally used for cooling purposes.
When necessary, the same plant can also be used for heating by passing hot water through it for heating purposes.
Likewise, fan coils are devices designed to fulfill both processes by feeding them with cold or hot water.
