太阳能辅助地埋管地源热泵复合系统过渡季运行模式

摘要

Compares the efficiency of heat utilization under two operation modes of timing and hourly thermal storage for the thermal storage subsystem of solar-assistod ground-source heat pump (SAGSHP) system in transition season.Provides the methods to determine the main equipment parameters for the two operation modes.Based on the simulation model built on TRNSYS platform,simulates the thermal storage status of the thermal storage subsystem with different solar collectors.According to the simulation results,evaluates the thermal storage efficiency of the two operation modes.%对比了太阳能辅助地埋管地源热泵复合系统在过渡季利用太阳能进行土壤蓄热时,定时蓄热与随时蓄热2种运行模式下蓄热子系统的热利用效率.给出了复合系统过渡季2种模式下蓄热子系统主要设备参数的确定方法.在TRNSYS平台搭建了蓄热子系统仿真模型,模拟了不同太阳能集热器面积下系统的蓄热情况.根据模拟结果对2种蓄热运行模式下子系统的蓄热效率进行了评价.
