Research on technology of mobile air conditioning room in mines

HU Han-hua GU De-sheng (School of Resources and Safety Engineering,Central South University,Changsha 410083,China)  
In the technology of the mobile air conditioning room(MACR),the heat barrier is used to isolate work- ers from the hot environment and the cooling air is supplied for the mobile air-conditioning room by the turbine- typed air cooler whose cooling source and ventilating power come from cooling energy and potential energy stored in the water in constant temperature zone.The experiments show that when the environment temperature is 32℃and the water of 18℃is supplied at the speed of 1.6 m~3/h,the dry-bulb air temperature in MACR can be cooled to 24℃below in 10 min.The air temperature can still be maintained at 28℃below after 30 min without the air cooler working.
