介绍热源塔结构组成及热泵工作原理,分析热源塔热泵的运行特点.以其办公建筑为工程模型,利用建筑热环境设计模拟工具包(designer's simulation toolkit, DeST)软件建立建筑模型,设置建构物参数和室内设计参数,模拟计算建筑全年逐时负荷,在此基础上,设计选择热源塔热泵和空气源热泵冷、热源方案的主要设备,计算不同方案全年能耗,对比分析对应的初投资和运行费用.研究表明,热源塔热泵的冷热源技术具有运行稳定、初投资低、年综合运行费用低以及能源综合利用效率高等优势,适于在冬季低温高湿地区推广.

We introduce the heat-source tower structure and its working principle and analyze its heat pump characteristics. By using DeST(designer's simulation toolkit)to simulate the year-round hourly cooling and heating loads of a building, we get the indoor parameters. According to these parameters, we select the main equipments of cooling and heating sources for air-conditioning systems of both heat-source tower heat pump and air source heat pump. By calculating the annual energy consumption, initial investment and annual operating cost, we find that the heat-source tower, with more stable operation, lower initial investment and annual operating cost is suitable for popularization in cold winters and in areas with low temperature and high humidity.
