摘　　要：目的提出太阳能与地源热泵联合供暖和交替供暖两种运行方式,解决太阳能和地源热泵各自单独应用时存在的缺陷.方法绘制两种供暖方式的原理图,对太阳能集热器、热泵机组和室内散热器建立数学模型;以沈阳地区为例,进行室外温度、逐时热负荷、太阳能辐射强度和热泵机组运行工况的模拟并且采用静态分析法计算两种供暖方式的经济性.结果两种供暖方式均能稳定的运行,而且就经济性来说交替性供暖在初投资上要比联合供暖高约28.4%,但是交替供暖一个供暖期的运行费用要比联合供暖大约低22.5%.结论将两种供暖方式的理论研究应用于实际工程中是具有可行性的,而且比较适用于热负荷大于冷负荷地区;在5个供暖期后,初投资较高的交替供暖开始显示出它的经济性;结合使用要比单独使用太阳能和地源热泵更具有节能性.The paper aims to propose two heating ways ：joint heating. Alternate heating. Analyze the feasibili- ty and the economics of two heating modes and solve defects of the solar and ground source heat pump sys- tem running alone. Draw two heating ways principle diagram and establish the mathematical model of the so- lar collector,heat pump units and indoor radiator. By taking Shenyang area as an example, simulate outdoor temperature, the heat load, solar radiation intensity and heat pump units running condition and use static anal- ysis method to calculate the economics of two heating ways. This study shows that two kinds of systems can all run stably ,and for economy, alternately heating costs about 28.4% more than joint heating in the initial investment,but the alternately heating running costs about 27 % less than joint heating in a heating period. Theoretical study of the joint heating method to be used in practical engineering is feasible, and the joint heating mode is more suitable for the area that heat load is greater than the cold load. After five heating peri- ods, higher initial investment of alternately heating begins to show its economy; comparing with the solar heat pump and ground source heat pump separately, they are all energy-saving.
