Environomic optimization of district heating network systems with both centralized and decentralized heat pumps.

Author(s) : CURTI V., FAVRAT D., SPAKOVSKY M. R. von

Summary

In Switzerland like in many countries, many of the populated areas are located close to lakes or rivers, offering a large potential for the use of heat pumps. Although district heating is an obvious solution, adapting the delivery temperature to the most exigent users is detrimental to overall system performance. The best system configuration could avoid this pitfall by relying on a centralized plant of heat pumps with cogeneration, supplemented by decentralized heat pumps for the more demanding users. Modelisation and optimisation of such systems are developed. Results are shown for various user distributions and fuel and electricity prices. A comparison between the results found with and without taking into account pollution is also presented.
