英国の住宅暖房における空気熱源ヒートポンプ（ASHP）に、潜熱・顕熱蓄熱を統合したシステムの技術経済性と環境性を評価。ASHP単体と比較し、蓄熱統合によりエネルギー消費を最大33%削減、LCOHを低減、CO2排出を大幅削減できることを示した。

English

This study evaluates the techno-economic and environmental performance of integrating thermal energy storage (PCM and water-based) with air-source heat pumps for UK residential heating. Results show significant reductions in energy consumption (up to 33%), lower levelized cost of heating, and reduced carbon emissions compared to standalone ASHP and gas boilers.

📄 Abstract（原文）

Air source heat pumps (ASHPs) are increasingly deployed in the United Kingdom as a low -carbon alternative to conventional gas boilers for residential heating. However, large-scale deployment of ASHPs may contribute to increased peak electricity demand during winter operation, resulting in higher operational costs and additional pressure on electricity networks. This study investigates the integration of thermal energy storage with ASHP systems, incorporating latent heat storage using phase change materials (PCM) and sensible heat storage (SHS) using water. A detached residential building under UK temperate climatic conditions is modelled to evaluate the performance of ASHP-LHS i.e. PCM and ASHP-SHS systems, compared with a standalone ASHP and a gas boiler. A comprehensive techno-economic and environmental assessment is conducted, including energy consumption, levelizised cost of heating (LCOH), and carbon emissions. The results show that for the model scenario, ASHP-SHS and ASHP-LHS systems reduce energy consumption by 21.62% and 33.23%, respectively, compared to a standalone ASHP. The LCOH decreases from £0.122/kWh (gas boiler) to £0.1012/kWh for the ASHP-LHS system. Carbon emissions are reduced from 4.94 tCO₂/year (gas boiler) to 1.46 tCO₂/year for ASHP-LHS. The findings demonstrate that integrating thermal energy storage has the entailed to significantly improves heat pump performance, offering a cost-effective and low-carbon solution for residential heating in the United Kingdom.
