4 pipe installation
DELIVERY FAN:
The fan is located just before the
Fan control
The air flows across the batteries before being released into the room.
If the control is installed on the fan coil unit itself, an additional return air sensor, positioned in the flow of inlet air detects
the room temperature. In this case, the temperature measurement is valid only if the flow of inlet air is sufficient to nullify
or reduce stratification phenomena in the room.
WATER BATTERY – MOTORISED
Consists of a water-air exchanger, located internally, across which the inlet air travels.
Finned battery
Hot or cold water, produced by a boiler or a chiller, flows through the exchanger.
There may be a dual battery supply circuit (4-pipes); the 4-pipe configuration may be set up with two motorised valves and
Valve
two independent exchangers, or with a single exchanger (2-pipes). In some cases it is important to be able to measure the
temperature of the water supplied to the battery, which may be done with a water sensor located downstream of the
battery's return and the valve.
