气动风机制冷系统被用来解决矿井热害问题,但是其效果不明显,提出带风冷器、套管式换热器气动制冷风机系统优化方案,利用热力学理论,结合T-s图,理论分析此方案的优越性,并通过实验验证达到了预期效果。 Pneumatic fan refrigeration system is used to solve the problem of thermal damage in mines, but its effect is not obvious. A scheme of pneumatic cooling fan system with air cooler and bushing heat exchanger is proposed. Based on the theory of thermodynamics and Ts map, the scheme is analyzed theoretically The superiority, and achieved the expected result through the experiment.
