【摘要】 以热负荷为主的北方地区,冬季土壤温度较低,若完全采用地源热泵来供暖,则地热换热器和机组的初投资均比较高,连续运行的效率也较低。提出利用风力发电机产生的电能构成风能集热器作为地源热泵供暖的辅助能源的构想。白天完全依靠地源热泵供暖,夜间利用风能集热器辅助加热,使地热换热器与风能集热器串联运行。通过分析比较,该方案比完全用地源热泵供暖更经济。更多还原

【Abstract】 In the northern,the temperature of soil is very low and heating load is dominant.If the peak load of heating was supplied by ground exchanger,the ground-source heat pump heating efficiency is low.Therefore the wind energy can be utilized as assisted source.In day,the heat is supplied by ground exchanger,and by ground exchanger and wind collector in night.The results show that the program is more economical.更多还原
