压风空调是煤矿井下避难硐室降温的有效手段。对比避难硐室几种常用的降温措施，该文提出了一种更为有效的降温手段——压风空调。该空调利用涡流温度分离效应，具有成本低、免维护等特点，已在煤矿中广泛应用。%The pressure air conditioning is an effective means of underground refuge room in coal mine cooling. Comparison of several commonly used measures to cool down the refuge chamber, this paper presents a more efficient cooling means -- pressure air conditioning. The air conditioning the use of eddy current temperature separation effect, has the characteristics of low cost, such as maintenance free, has been widely used in the coal mine.
