摘要

为有效解决日光温室大棚中地源热泵（GSHP）系统运行导致的土壤温度逐年降低和太阳能辅助地源热泵系统（SAGSHP）导致的夏季土壤温度过高的问题

提出一种SAGSHP跨季节分区蓄热模式

将地埋管分为4个区域

采用TRNSYS-18软件

通过对不同跨季节分区蓄热运行模式的仿真模拟

得到最佳分区蓄热策略。结果表明：最佳模式为春季过渡与供冷季1/2区域连接太阳能蓄热

秋季过渡与供暖季全区连接太阳能蓄热

同时秋季过渡季1/2区域供暖或供冷

其余时间段全区供暖或供冷。最佳模式土壤温度在10 a内保持稳定

热泵机组在夏季运行时其性能系数（COP）降低最为缓慢

机组运行稳定性高于传统SAGSHP系统

10 a内系统运行的性能系数（SCOP）平均每年高于GSHP系统57%、高于传统SAGSHP系统5.4%

且最佳模式系统运行SCOP逐年升高

第10年最佳模式系统运行SCOP高于GSHP系统70.6%、高于传统SAGSHP系统10.4%。

Abstract

To effectively address the issues of soil temperature decreasing annually in ground source heat pump （GSHP） systems and excessive soil temperature in summer caused by solar-assisted ground source heat pump （SAGSHP） systems in solar greenhouses

this paper proposes a cross-seasonal partitioned thermal storage mode for SAGSHP systems. The buried pipes are divided into four zones

and TRNSYS-18 simulation is used to model different seasonal operation modes

leading to the optimal partitioned thermal storage strategy. Results show that the optimal mode involves connecting half of the solar thermal storage during the spring transition and cooling seasons

and the entire area during the autumn transition and heating seasons. Additionally

during the autumn transition season

half of the zone provide heating or cooling

while the entire area is used for heating or cooling during other periods. In this optimal mode

soil temperature remains stable over ten years

the Coefficient of Performance（） decrease in summer is minimized

and the system's operational stability is higher than traditional SAGSHP systems. Over ten years

the System Coefficient of Performance （） is on average 57% higher than GSHP systems and 5.4% higher than that of traditional SAGSHP systems. In the tenth year

the is 70.6% higher than GSHP systems and 10.4% higher than that of traditional SAGSHP systems. This study provides a reliable strategy for the efficient and stable operation of greenhouse GSHP systems.
