摘　　要：分析了寒冷地区高层建筑供暖空调的特点,提出了四种可供高层建筑使用的、以空气为低位热源的双级耦合热泵系统。选择一幢写字楼,以空气源热泵+热泵型水冷VRF系统为例,通过建立数学模型,模拟分析了该系统在寒冷地区代表城市的运行特性,并与传统的低温空气源热泵系统进行了经济性比较。Analyses the particularity of heating and air conditioning systems of high rise buildings in cold areas and puts forward four kinds of double coupling heat pump systems with the air as low-level heat source to be used. Simulates and analyses the operation performance of the double coupling system with air- source heat pump and VRF water-source heat pump in an office building by establishing its mathematic model. Compares the economic efficiency between the system and the conventional low temperature air- source heat pump system.
