Experimental data from AIT monitoring data December 18, 2015

Extends from BaseClasses.PipeDataBaseDefinition (BaseClass for experimental data from the pipe test bench).

Information

Overview

This record contains data of a real disitrict heating network for week-long period (23-29 Januar 2009) monitored by the Austrian Institut for Technology.

Pipes are layed underground

Column 3: Temperature in point 2 in K

Column 4: Temperature in point 3 in K

Column 5: Temperature in point 4 in K

Column 6: Mass flow rate in point 1 in kg/s

Column 7: Mass flow rate in point 2 in kg/s

Column 8: Mass flow rate in point 3 in kg/s

Column 9: Mass flow rate in point 4 in kg/s

Column 10: Outdoor temperature in K

Test procedure

Information at several points of the district heating network is recorded during a week.
