Application of simulation in design and operationof refurbished buildings and heating systems

摘要

This paper gives an introduction into the simulationrnof the thermic behaviour of a modernized buildingrnincluding the calculation of both single and two pipernheating by a new TYPE57 for simulation of heatingrnpipe systems within the program TRNSYS. The datarnsimulated are compared with measurements. Thernoccupancy behaviour and the kind of decentralrncontrol have a decisive influence on heat consump-tionrnwithin a building.
