Building integrated PV water heating and air conditioning in the special hospital of the SPA Rusanda

摘要

Different types of thermal activation of building structures are increasingly utilized in buildings including BIPV, multifunctional PV facades with controllable daylight/solar gain features and integrating thermal and electrical output. Much of the existing R&D is focused on these facades and structures with the rest of the building, but detailed information is scarce on relevant properties and the performance. This paper presents dynamic analysis and optimization results of PV air-conditioning and PV based sanitary water heating system, which by heat recovery assisted, demonstrates cost effectiveness which significantly surpasses the corresponding values of direct solar thermal conversion systems. The study objective was to propose technical solution for replacing fossil fuel and electricity with solar energy for air conditioning in addition to water heating for different purposes (pools, sanitary water, washing) in the Special hospital of the Spa Rusanda - Melenci. Crucial for the study success was prediction of air-conditioning loads and synergetic relations between energy efficiency, solar radiation intensity stochastic changes, PV system's electricity production and sanitary water consumption dynamics.
