Abstract

Achieving net-zero emissions in residential heating requires sustainable alternatives to gas-powered systems and effective use of existing gas infrastructure. This study introduces ice-source heat pumps, leveraging the latent heat of fusion for efficient heating combined with innovative water transmission methods.

The system offers advantages such as compact design, cost-effectiveness, and reduced electricity consumption without requiring new piping infrastructure. While slightly less efficient than water-source systems, ice-source heat pumps reduce water consumption by 37.56 times, with minimal thermal losses, making them highly effective during peak cold periods. For an average UK residential unit, the water distribution network capacity required is 2.3 times greater than the potable water network for average monthly use and 4.88 times greater under peak conditions without auxiliary systems.

The feasibility of repurposing gas pipelines after phasing out natural gas was also examined. Results show repurposed pipelines can provide water transfer capacities equal to 39.66 % of the energy previously supplied by natural gas during peak demand, making this approach valuable for non-fuel heating systems.

冰源热泵：利用水和天然气网络为城市地区提供可持续的供暖解决方案

在住宅供暖中实现净零排放需要可持续的天然气动力系统替代品和有效利用现有的天然气基础设施。本研究引入冰源热泵，利用融合的潜热进行高效加热，并结合创新的输水方法。该系统具有设计紧凑、成本效益高、减少电力消耗等优点，无需新建管道基础设施。虽然效率略低于水源系统，但冰源热泵减少了37.56倍的用水量，热损失最小，使其在高峰寒冷时期非常有效。对于一个普通的英国住宅单位，所需的配水网络容量是平均每月使用的饮用水网络的2.3倍，在没有辅助系统的峰值条件下是4.88倍。此外，还研究了在逐步淘汰天然气后重新利用输气管道的可行性。结果表明，在高峰需求期间，重新利用的管道可以提供相当于以前天然气供应能源的39.66%的水输送能力，使这种方法对非燃料加热系统具有价值。
