土壤源热泵系统运行策略及优化分析

Operation Strategy and Optimization Analysis of Ground Source Heat Pump System

针对土壤源热泵系统供冷工况运行控制策略多样,系统能耗受策略影响较大,导致实际运行能耗较难达到设计目标的问题,对系统常规运行策略能耗进行了分析。在温差控制策略的基础上,提出基于优先采用低品位热源的原理,对运行控制策略进行节能优化。优化结果表明:供冷工况系统运行能耗较地埋管优先、冷却塔优先、温差控制策略下分别降低3.89%、4.71%、0.82%。

According to multiple control strategy influencing energy consumption on cooling mode and inaccessibility to the design target in ground source heat pump system operating,conventional operation energy consumption of the system is analyzed.On the premise of temperature difference control,operation strategy is optimized based on the principle of low-grade heat source used in preference.The results show that cooling operation energy consumption decreased respectively 3.89%,4.71%,0.82%compared with buried pipe priority operation,cooling tower priority operation,temperature difference control operation.
