Hot Water Recirculation and Control, a Solution to Reduce Energy Consumption
Journal Title: Analele Universitatii "Eftimie Murgu" Resita. Fascicula de Inginerie - Year 2015, Vol 22, Issue 1
Abstract
For the energy consumption reduction in the buildings sector, EU pro-poses guidelines regarding energy performance. EU Member States must take measures to ensure the conversion of buildings into nearly zero energy buildings, which should also include measures to optimize installations for domestic hot water (DHW). From this point of view the present paper deals with issues regarding hot water recirculation and control aiming to reduce fuel consumption necessary for DHW preparation. To this end the benefits of DHW preparation process optimization were analyzed, in order to ensure a theoretical constant temperature having values in a narrow domain and an efficient thermal fluid distribution in the network for better controlling hot water temperature.
