混合式地源热泵系统不同控制策略的分析与比较
Analysis and comparison of different control strategies for hybrid ground-source heat pump systems
摘要：
提出了适用于最常见的两种混合式地源热泵系统——冷却塔-地源热泵系统和锅炉-地源热泵系统的控制策略。选取武汉和哈尔滨为代表城市，以某一小型办公楼建筑为研究对象，对两种混合式地源热泵系统在不同控制策略下的运行情况进行了仿真，分析比较了各种控制策略下的热平衡及能耗状况。

Abstract：
Provides control strategies being applicable for two kinds of common hybrid ground-source heat pump systems—the cooling tower-ground source heat pump system and the boiler-ground source heat pump system. Selecting Wuhan and Harbin as representative cities and taking a small-sized office building as study object, simulates the operation conditions of the two systems under different control strategies, and analyses and compares the heat balance and energy consumption.
Keywords:hybrid ground-source heat pump system, cooling tower, boiler, control strategy
