AI Technical Summary
Technical Problem
这种方法缺乏理论依据，在极度潮湿或干燥的矿井环境中，误差巨大，使总冷负荷计算不足，所选空冷器制冷量无法将空气处理到设计要求的温湿度状态点，造成降温除湿效果不达标；若是采用简化粗略的潜热负荷处理方法，又可能导致对负荷的计算不准确，所选空冷器制冷量过大，不仅增加了初期设备投资，更会导致设备在部分工况下频繁启停或低效运行，浪费大量电能
Benefits of technology
本发明通过确定空冷器进、出口空气状态及矿井风流体积流量；然后基于焓湿学原理，计算空气处理过程的焓差，从而精确得到包含显热和潜热两部分的总冷负荷；最后根据此总冷负荷值，考虑安全余量后对空冷器进行选型；
