摘要(Abstract)：

针对寒冷地区周边无热网且环境要求较高的建筑对象,提出了利用低谷电驱动的空气源双级耦合热泵蓄能空调系统,介绍了系统的组成和运行原理,分析确定了系统优化目标变量,建立了系统优化数学模型,针对126m2某办公建筑,研究了热泵容量和关闭温度对经济性的影响规律,结果表明:在乌鲁木齐的气候条件下,热泵的最优关闭温度为-20℃,额定制热量为8k W,系统全年平均COP为1.71,系统全年运行费用仅较集中供热和分体空调方案高4%,表明该系统具有一定的应用可行性。
Aim at the buildings with no heating network around and high environmental protection requirements in cold areas,the air source double stage coupled heat pump conditioning system with an energy storage tank driven by the lower price electricity was put forward. The system composition and operation principle were introduced,and then the optimization target variable was determined by analyzing,the mathematical model was set up for system optimization design. Taking the 126m2 office building as the research object,the impact on the economy about capacity and shutdown temperature of the heat pump was studied. The results show that under the climate condition of Urumqi,the optimal shutdown temperature of coupled heat pump is 20℃,rated heating capacity is 8k W,the annual system average coefficient of performance( COP) is 1. 71,and the annual operating cost is 4% higher than the centralized heating and split air conditioning scheme. The above results indicate that the system has certain feasibility.
