Innovative Hybrid Condensing Radiant System for Industrial Heating: An Energy and Economic Analysis

In this paper, an innovative hybrid condensing radiant tubes heating system for industrial building is modelled in three climatic zones of Italy using dynamic simulation software. Radiant are coupled with air–water heat pump, the latter serving air terminals located building. The energy performance optimized by evaluating best nominal power cut-off temperature a bivalent parallel operation, alternative and peak photovoltaic on roof Energy savings between 40% 80% calculated respect to traditional systems, considering different configurations climates. An economic analysis also allows evaluation advantages buildings.
