Abstract
This master’s thesis investigates the impact of cold climate weather patterns on the thermal performance of two novel designs of extruded photovoltaic thermal (PVT) collectors, optimized for integration with low-temperature heat pumps. The study aims to provide a comprehensive understanding of how different weather conditions, including condensation, rainfall, frost formation, and snow, affect the thermal output of these systems. The thesis compares two PVT designs, one with fins and another without, to determine the optimal configuration for maximizing efficiency under varying cold climate conditions. The methodology involved a detailed literature review, the design and execution of experiments in an outdoor laboratory, and the analysis of thermal performance data categorized by weather patterns. The results indicate significant differences in performance between the finned and non-finned designs, as well as a strong impact on the thermal performance of the PVT as a result of the different weather patterns. This research fills a critical gap in the understanding of PVT performance in cold climates and provides insights into the appropriate control strategies for heat pumps to enhance system efficiency. The findings offer a valuable contribution to the development of more efficient renewable energy systems in regions with harsh winter conditions.Description
