InfoFLUX, developed by ANIT (Italian National Association for Thermal and Acoustic Insulation), allows the calculation of the thermal conductance, from which the thermal transmittance value U is derived. This is a physical quantity that is used to calculate the thermal losses through a surface (e.g. an external wall). The lower its value, the lower the thermal losses will be.
For each measurement point, the InfoFLUX program performs thermal conductance calculations using two methods: “method of flowing averages” (ISO 9869: 1994) and “black box method” which processes the values with a statistical method, this method allows to obtain the result in a shorter time than the “sliding averages” method.
The program needs as input an ASCII file containing the values of:
- N.2 Temperature in contact with the external wall
- N.1 Temperature in contact with the internal wall
- N.1 Thermal flow through the wall
