| Summary: | Cool-storage density is one of the most important parameters for evaluating the performance of refrigerant hydrate. A calorimetric device was set up and a mixing calorimetry method was established to measure the cool-storage density of hydrate slurry according to the law of energy conservation. The cool-storage densities of hydrate slurries formed from R141b/H2O coarse mixture and R141b/H2O microemulsion were measured within 4-12 ℃. The results are 49.6 kJ/kg and 99.1 kJ/kg, which are about 1.5 times and 3 times of that of water, respectively. Volume of storage tank could be reduced significantly by utilizing refrigerant hydrate slurry instead of water. |
