A METHOD FOR OPTIMIZING THE POWER USAGE IN A DISTRIC HEATING SYSTEM.

摘要

The present invention concerns a method of optimizing the power usage of district heating systems. A district heating system has a central unit (1), such as a power plant or an intake from a larger system, and a number of local units (2), normally different buildings. The local units (2) pick up heat from water delivered by the central unit (1), by means of heat exchangers (9, 10). The present system has means for monitoring and control of the central unit (1) and the local units (2). The data picked up by the means for monitoring and control are used for the optimizing of the power usage. The power outtake of the district heating system is regulated by reduced flow into one selected local unit (2) during a short time period.
