Système de chauffage urbain géothermique fournissant deux niveaux de température d’eau chaude pour les radiateurs et le chauffage radiant par le sol.
A geothermal district heating system supplying two kinds of hot water temperature for radiators and radiant floor heating.
Résumé
With the rapid development of radiant floor heating in residential buildings, high‐temperature water for radiators and low‐temperature water for radiant floor heating are needed simultaneously. As a renewable energy solution, the geothermal district heating system(GDHS) is used. In this paper, a GDHS supplying dual‐temperature hot water for radiators and radiant floor heating is proposed based on absorption heat pumps(AHP‐GDHS). The mathematical model of AHP is verified and the AHP‐GDHS system is constructed for design application. The influence of geothermal water supply temperature and heating load ratio of radiators on the performance of AHP‐GDHS are explored. Finally, GDHS using heat exchangers for dual temperature supply(HX‐GDHS) is compared with AHP‐GDHS. Results show that AHP‐GDHS has advantages in terms of energy utilization and the payback period is 3.77 years. The proposed GDHS which can supply two kinds of hot water temperatures will benefit the district heating system which exists different heating terminals.
