초록
In this study, a convergence technology that can be linked with photovoltaic thermal (PVT) modules was derived to increase the performance and efficiency of air source heat pumps that are currently most widely used as cooling, heating, and domestic hot water supply equipment in public buildings. The solar energy and air source heat pump convergence technology developed through this study was an indirect supply type outdoor unit heating system that supplied heat energy acquired through a PVT module by increasing the temperature of the air flowing into the outdoor unit when the heat pump heating mode was operating. A bench-scale test device was designed and manufactured to verify the performance of the outdoor unit heating system of an air source heat pump using a PVT module. The performance evaluation confirmed that the heating performance of the air source heat pump was improved compared with that of the conventional air source heat pump without the heating system under the same test conditions. In addition, the heating demonstration was performed by applying the air source heat pump outdoor unit heating system using a PVT module to the air source heat pump installed at the Seodaemun Fire Station Hongeun 119 Safety Center, where an actual public building was remodeled. Consequently, the air source heat pump was heated. The analysis revealed that COP increased by more than 0.5.
