ENERGY AND COMFORT - A NEW-TYPE FOR TRNSYS

Two subroutines have been developed which permit users of the TRNSYS p rogramme to calculate the parameters of ambiental comfort (PMV and PPD ). The first subroutine deals with the calculation of the view factors inside a room for all the values of the spatial coordinates and, thus , permits the average radiant temperature to be calculated in every po sition. The second subroutine. has been developed in accordance with t he indications of the ISO 7730 standard. Both subroutines have been va lidated and then interfaced to TRNSYS. The integrated programme has be en utilised to compare the performances of different heating systems i n terms of energy consumption and comfort, maintaining the temperature of the interior constant for different climatic conditions.
