As the Xingtai Mine thermal power plant was suspended, and there is no available heat source around the mine, in order to solve the problem of workers bathing, the pressure machine waste heat, air source heat pump as a heat source, electric heating as an auxiliary heat source plan was given. water tank capacity, thermal storage capacity, system operation control order, affect system efficiency and stability. The equipment selection, design scheme and system operation control system were introduced, through the data acquisition and calculation, the waste heat of the air compressor is the most preferential utilization of heat energy, and the air can be secondary, so as to minimize the use of electric heating. The system saves operating costs and achieves good operating results.
