A marine waste heat-driven ammonia absorption refrigeration system and method belong to the field of marine energy conservation and absorption refrigeration technology. The system uses the low-temperature waste heat of the cylinder liner water (65℃-95℃) of the marine diesel engine as the driving heat source, employing a novel ammonia-salt working fluid pair. It forms an absorption refrigeration circuit consisting of a generator, condenser, throttle valve, evaporator, absorber, solution pump, and solution heat exchanger, and is equipped with a waste heat supply circuit and a cooling capacity output circuit, simultaneously providing cooling for the ship's air conditioning and refrigeration systems. The salt solute used in this invention has high solubility in ammonia and is non-volatile. The ammonia gas obtained from the solution heating and desorption is of high purity, eliminating the need for a distillation device. The system is compact, small in size, and low in cost, making it suitable for the space-constrained environment of ships. By replacing electric compression refrigeration with absorption refrigeration and using environmentally friendly ammonia refrigerant instead of high GWP refrigerants, it significantly reduces marine fuel consumption and carbon emissions. The system operates safely and stably, with high energy efficiency and waste heat utilization, meeting the needs of maritime emission reduction and ship refrigeration.
