摘要
浅层地温能是一种经济、清洁的新型能源,我国可供开发利用浅层地温资源潜力巨大。文中提出了浅层地温潜力的评价方法,并结合我国浅层地温能开发利用的情况,对我国31个省、市、自治区(284个地级市)进行了浅层地温资源潜力评价,其总量为7.0×1011kWh/a,在此基础上,依据能量均衡原理,对可利用的潜在浅层地温能进行了可装备空调面积计算,其总量为1.7×104km2/a,则可供1.3亿人取暖,4.3亿人制冷,每年节约2.3亿吨标准煤,减少6.1亿tCO2、198万tSO2以及173万tNxOy温室气体排放,对于节约供暖(或制冷)成本,减少温室气体排放,缓解全球气候变暖具有重要的意义。
Shallow geothermal energy is one of the economic and clean energies.It was showed that about 7.0×1011 kWh of shallow geothermal energy could be used for heating and cooling each year,evaluated by reservoir assessment method in 31 provinces,municipalities and autonomous regions of China.According the energy conservation principle,it the whole shallow geothermal energy was used for air-conditions,then the area for heating with of air-condition could be about 0.4×104km2/a,which could be used for heating for 1.3 ×104 persons.And for refrigeration 4.3×104 persons.It could reduce about 2.3×108 tons standard coal used by human,about 6.1×108 tons CO2,1.98×106 tons SO2 and 1.73×106 tons NxOy discharged,which could reduce the trend of global warming.
