Abstract: According to a low automation degree and serious electric power waste status of the equipments applied in the freezing station of the mine freezing sinki ng method, the energy saving control system of the heat exchange was designed and a fuzzy controller was applied to control the brine temperature and flow. Accordin g to the actual heat exchange scale of the freezing project, the equipment operation status was adjusted. The brine pump in the system would apply a frequency conver ted controller to change the revolution speed of the driving electric motor to adjust the brine flow, the compressor group would apply rational on-off compressor group to realize the brine temperature control and could make a supply based on the demands. From the actual application effect, the system with excellent control performance s could expand the equipment service life, could save great electric power and could reduce the electric power consumption cost of the construction enterprises.
