Abstract

This study investigates the energy savings and thermal efficiency of glazed balconies with integrated heat pump systems for residential heating in cold climates. Furthermore, this study explores the integration of solar-absorbing materials on walls and floors of the balcony to enhance solar heat gain, along with the thermal benefits of a mini-split heat pump during test days. These enhancements are designed to improve energy efficiency, indoor comfort, and temperature regulation. Within the scope of the study, various evaluations such as thermal efficiency, the heat pump coefficient of performance, and temperature differences are made on different days and under different operating conditions. From the results obtained, it was observed that the thermal efficiency of the modified balcony reached 13.9 % when the mini-split heat pumps were not in operation. The COPHP values of the employed heat pump were assessed under various operational conditions. It was determined that the maximum COPHP value could surpass 3, yet the maximum average COPHP between 7:00 and 17:00 h was approximately 2.73. Consequently, this study proposes the exploration of larger sunspaces within substantial structures such as university faculties, libraries, and offices, presenting additional avenues for research. This underscores the potential for a more efficient utilization of a combination of solar energy and heat pump applications.
