【摘要】 自上世纪九十年代起,空气源热泵机组在中国南方得到了广泛的应用,但是当在北方地区使用时,冬季较低的室外温度将导致机组运行效率的降低,因此必须对空气源热泵机组在中国北方的应用进行经济性分析。本文建立了空调冷热源系统的热经济学模型,在此模型和能耗计算的基础上,计算分析了空气源热泵系统和其他冷热源系统在西安地区应用的年度总成本,结果表明空气源热泵在中国北方地区的使用有较好的前景。更多还原

【Abstract】 Air source heat pump has been widely used in south China since 1990s. Due to the reduction of performance efficiency of air source heat pump in north China brought by comparatively low outdoor temperature in winter, the economics of air source heat pump used in north China should be analyzed. In this paper, a thermoeconomic model of heating/cooling system, which was the subsystem of building air conditioning system, was established. Based on the thermoeconomic model and the energy consumption calculation, the annual total cost of air source heat pump system and other heating/cooling system in Xi’an city, China, was calculated and analyzed. Results shown that the utilization of air source heat pump has a bright future in northern China.更多还原
