Absorption ice slurry generator is proposed for low-level unused energy utilization. Ice slurry is generated by absorption refrigeration cycle using ethanol solution as a refrigerant, and LiBr-water-ethanol mixture as an absorbent. In advance, the saturated pressure of the mixture of 3 components was measured, since it has not been known. Using the measured data, the COP of the ideal cycle of this absorption ice slurry generator was estimated. As a result, we concluded that this system will be useful, because the COP of this cycle is comparable with existing absorption refrigerators. Using double lift cycle, the temperature of evaporator/ice slurry can be decreased below −15°C. Due to this, the use application of the ice slurry will be expanded. Additionally, this cycle is suitable for low-level unused energy utilization, because it can be operated by relatively
