Abstract

Optimal supply strategies are a promising and inexpensive way to improve energy e ffi ciency and to reduce expenditure in district network energy supply. These strategies aim to reduce heat losses by modifying the supply temperature within its working boundaries. Through supply temperature adjustment and network ’ s thermal mass it is possible to modify the energy stored in the network and to use it as an active energy storage. In this work, scenarios with variable and fi xed supply temperature are compared during four weeks representing the di ff erent seasons. The simulations are carried out using an energy management system. Results of both scenarios for a district heating and cooling network placed in the Mediterranean region are presented and discussed
