摘要

针对地源热泵系统在长周期供暖过程中地温逐年下降，耦合太阳能跨季节蓄热导致全年能效降低的难题，提出了一种新型运行模式——“先蓄热后供热”模式，以提升耦合供暖系统的整体能效。基于温室供暖实验数据，采用TRNSYS软件构建仿真模型，分析了无蓄热、后蓄热和先蓄热3种模式下的地温变化特性和供暖能效。该“先蓄热后供热”模式通过供暖前的太阳能跨季节蓄热，实现太阳能与浅层地热能的高效耦合，在改善地温失衡的同时，显著提升供暖能效，并在20年运行周期内保持稳定。相较于“先供暖后蓄热”模式，该模式的全年能效提升4.4%~4.2%，20年累计节电约1.07×10

kW·h，年均节电534 kW·h，直接节省运行能耗成本4.2%，有效降低了系统能耗、提高了供暖经济性。

Abstract

To address the challenges of the long-term decline of geothermal temperature in ground source heat pump (GSHP) systems and the efficiency reduction caused by the coupling of seasonal solar heat storage (SSHS)

this study proposes a novel operational mode—the 'store-then-supply' (SSHS+GSHP) mode—to enhance the overall efficiency of the coupled heating system. Based on greenhouse heating experimental data

a simulation model was developed using TRNSYS to analyze the geothermal temperature variation and heating efficiency under three different modes: no-storage mode

supply-then-store mode

and store-then-supply mode. The proposed 'store-then-supply' mode leverages seasonal solar heat storage before the heating period

achieving efficie

nt coupling of solar and shallow geothermal energy. This approach not only mitigates geothermal imbalance

but also significantly improves heating efficiency

maintaining a stable performance over a 20-year operational period. Compared with the 'supply-then-store' mode

the proposed mode improves the annual energy efficiency by approximately 4.2% to 4.4%

achieving a cumulative electricity saving of about 1.07 × 10

kW·h over 20 years and an average annual saving of 534 kW·h

directly reducing the operating energy costs by 4.2%

effectively lowering system energy consumption and enhancing heating cost-effectiveness.
