土壤直接供冷空调系统模拟研究

Simulation Study of Soil Direct Cooling Air-conditioning System

针对空调夏季耗电高的问题,提出以土壤作为冷源直接供冷空调的思想。采用有限元理论,研究土壤直接供冷空调系统土壤温度变化规律,给出系统蓄冷、取冷阶段土壤温度场在不同埋深时的温度变化趋势,确定土壤取冷结束后土壤热平衡的能力,分析结果对实际应用具有一定的理论指导作用。

Aimed at high consumption of electric of air conditioning system in summer, an idea of direct cooling air-conditioning using soil as cooling source was advanced. Adopting finite element method, soil temperature variety law of direct cooling air-conditioning system was studied. Variety trend of soil temperature in different deepness of storing and extracting cooling period were given. Ability of soil thermal balance after extracting cooling period was determined. The result has some theoretical function for oractice use.
