Application of Multi-functional Refrigerating Unit in Mine Cooling and Waste Heat Recovery |
|
| Abstract: | According to the needs of underground cooling,ice-making condensation heat recovery and water source heat pump system standby unit selection in the Wutongzhuang Coal Mine,the use of multiple-operating condition of heat pump type refrigerating unit as the refrigeration of underground local cooling well ice-making system was proposed,ice-making and heating in summer and heating in winter were achieved,and then the working principle of the system and process flow were discussed,coefficient of performance evaluation about " cooling and heating" for multi-functional refrigerant unit is proposed,and the unit performance for different working conditions were comparatively analyzed.Finally the running test showed that the system meeted the different working conditions in normal operation. |
| Keywords: | multi-function heat pump refrigeration unit mine cooling waste heat resource |
