摘要：

A heat pump-based mine solution dehumidification and cooling system is used in deep mines, which can not only reduce the temperature and humidity of the working face, but also recycle the low-grade heat energy and improve the utilization rate of energy.Under the condition of long distance air supply, within the range of 10m from the heading face, the equivalent temperature of the air can fall to 24.7 degrees C, the cooling range is 5.6 degrees C, and the relative humidity decreases by 23.79%. Compared with the original cooling system, the COP value of the system can reach 3.43 under the same working conditions, 19% higher than the original cooling equipment.
