Dynamic Simulation of High Temperature Solar Heating and Cooling Systems
Abstract
This paper presents a dynamic model of a solar heating and cooling system (SHC) based on parabolic-through solar collectors (PTC). The SHC system under investigation is based on the coupling of PTC with a double single-stage LiBr-H2O absorption chiller; auxiliary energy for both heating and cooling is supplied by a biomass-fired heater, fed by wood chips. The SHC provides space heating and cooling and domestic hot water for a small university hall. The system was dynamically simulated in TRNSYS. A parametric analysis was also performed, varying climatic conditions as well as parameters regarding the design and the operating mode of the system.
