本文论述了典型深井降温空调系统的技术特点，提出了我国深井降温系统应用年计算 费用法进行技术经济分析的方法。工程实例的技术经济比较表明，深井降温应用冰冷却系 统比常规矿井空调系统具有更大的优越性。 This paper discusses the technical characteristics of a typical deep well cooling air-conditioning system and puts forward a method for technical and economic analysis of the deep well cooling system in China using annual cost-of-calculation method. Engineering example of the technical and economic comparison shows that deep cooling application of ice cooling system has more advantages than conventional mine air conditioning system.
