The invention discloses an ice making system capable of recycling heat. The ice making system is applied to recycling the heat generated by a converter valve. The system comprises a heat pump system and an adsorption-type ice making system. The heat pump system is connected with the converter valve and used for improving the heat energy grade of the heat generated by the converter valve to obtainhigh-grade heat energy; the adsorption-type ice making system is connected with the heat pump system and used for conducting ice making according to the high-grade heat energy. By means of the ice making system, the heat of the converter valve is effectively absorbed through the heat pump system for recycling, the situation that the heat is directly discharged into the atmosphere is avoided, and the energy is saved; the heat pump system applies work on this part of heat, the heat energy grade is promoted, the heat of the high-grade heat energy drives the adsorption-type ice making system to run, the cooling capacity is reserved for production and life, and investment in external cooling equipment and production and living air-conditioning equipment of the converter valve is reduced.
