Abstract:

In this study, we examine several performance indicators of heat pumps used in cold regions, especially the amount of COP and SPF given. Heating pumps are gradually gaining a reputation as one of the most efficient solutions that can replace traditional heating equipment. That said, their benefits are yet to be realized where there are extremely unfavorable weather conditions during winter. As this paper has elaborated through the examination of case studies and experimental data, it is thus the objective of this research to establish the feasibility of using the heat pump to maintain very high-efficiency value in a region where demands for space heating are significantly high due to extreme sub-zero temperatures. It focuses on the changes in heat pump systems where the researchers have employed modified vapor injection and variable-speed compressors for better functionality during cold climates. As our evidence shows, these new heat pumps can indeed bring significant energy bottom the Dollar and cut greenhouse gas emissions simultaneously, even in the most adverse circumstances. This places them in ideal grounds to be adopted throughout the wintering countries where conventional heating equipment, whose source is fossil fuel, pollutes the environment and consumes much energy. The findings of this research not only indicate that heat pumps could be an effective heating solution for near-zero buildings in cold climates but also reveal the route map for enhancing the performance of heat pumps, which will help in making heating sustainable in the future.
