Abstract: A heating method using air compressor combined with air source heat pump as heat source is proposed, use to meet the annual hot water demand of coal mine workers. Combined with the calculation and analysis of engineering examples, Explain the feasibility of this technology in theory and practical application. This method can recycle a large amount of waste heat of air compressor, combined with air compressor waste heat recovery system and air source heat pump system, it can replace the heating mode of gas boiler. The payback period of the project is only 2.67years, which is a technology worth promoting.
