REHEATER NF
LPHW reheater for local heating of ducted air.
The valve-controlled air reheater NF serves to reheat the supply air and is mounted of the airflow control unit (if installed). By means of a connecting enclosure with circular sockets, connection to a round-profile air distribution duct can be made.
The heating output on the air side (as a function of the airflow volume) and temperature increase on the air side can be determined from the diagram. In addition, it is possible to determine the necessary water flow rate for the heating output as a function of the temperature range between the hot water supply and return flow systems, In the upper part of the diagram, it is possible to read off the acoustic power level and the pressure losses on the air and water sides.
The graphs in the diagram are based on an air inlet temperature of 14 °C and an economical low-temperature heating system giving a water supply temperature of 50 °C
