Abstract: In view of the problems in traditional mine cooling system，high energy consumption and high humidity at working face，combining with the special environment and requirement of deep mine，a temperature and humidity independent control cooling system for deep mine is proposed.Since cold water does not finish dehumidfication task，the system will adopt natural cold sources or high-temperature chiller with high COP to bear high sensible heat load，and the rotary-type dehumidifier to bear latent heat load.Then，the residual heat and waste heat in deep mine are used as the regenerative heat source for dehumidification.The thermodynamic calculation on a case shows that:the temperature and humidity independent control cooling system can be applied in cooling deep mine well.It can effectively improve the deep mining environment，and also lower the energy consumption.It is a worthy popularizing cooling system for deep mine.The energy consumption by a case shows that when the cool source adopts high temperature chiller unit，the regenerative heat source are heated by electricity，and the relative temperature and humidity at working face approaches to be saturated，the energy consumption of the independent control cooling system above is slightly lower than that of the conventional cooling system.Further analysis shows that:the larger moisture load at working surface，the more obvious energy saving of the temperature and humidity independent cooling control system.With the full use of residual heat，waste heat and natural cooling source，the energy consumption will be lowered further.
