Correlation between meteorlogical data and heat load in a district heating system

Other conference contribution, 1979

A model based on a theoretical analysis of the heat flow in buildings was developed. Outdoor temperature, wind velocity, and solar irraniance are the model parameters. Constants are employed to describe domestic hot-water demand, distribution losses and other variables ascociated with the users. Heat load statistics and metereological data for the years 1969-1976 were processed to provide estimated of these constants for the diatrict heating system of Malmö (1200 MW connected load in July 1978). The model can be used to study the passive solar gain and the influence of wind dependent natural ventilation. Examples of applications are shown.
