为寻求规模化猪场环境控制中的节能减排措施,根据地源热泵技术在规模化猪场应用的实例,计算分析其投资的经济可行性和节能减排效果.结果表明,地源热泵系统较燃煤锅炉系统增加了环境控制设备投资,在现行煤电价格体制下,额外静态投资回收期6.4 a.地源热泵系统比传统的燃煤锅炉节能,热泵机组的理论COP大于4.0,一次能源利用效率大于1.28.地源热泵系统的CO2减排量为燃煤锅炉供暖方式排放量的60%.另外,在猪舍夏季降温方面,地源热泵系统较传统的蒸发降温方式节水.地源热泵系统是一种节能减排的规模化猪场环境控制方式.%In order to find energy saving and emission reducing measures in environmental control of scaled pig farms,indices of energy saving and emission reduction were calculated and investment economical feasibility was analyzed based on an example of application of ground-source heat pump to scaled pig farm. The results showed that the investment of equipment of ground-source heat pump system was large than that of coal-fired boiler system; the static capital payback period was 6.4 years in present price system of coal and electricity. Ground-source heat pump system could save more energy than coal-fired boiler system, the coefficient of performance (COP) of the ground-source heat pump was more than 4.0, and the primary energy ratio was more than 1.28. In comparison with coal-fired boiler system,ground-source heat pump system could reduce CO2 by 60％ and save more water than traditional evaporative cooling system. Therefore, it is an energy saving and emission reducing mode of environmental control for scaled pig farms.
