<p>PURPOSE:To enlarge the capacity of an abosrptive freezer having a water cooling system, by using an aqueous solution containing an absorbent composition based on a Li-salt consisting of lithium bromide and lithium iodide as the absorbing liquid of the absorptive freezer. CONSTITUTION:An aqueous solution containing an absorbent composition based on a Li-salt consisting of 70-99mol% lithium bromide and 30-1mol% lithium iodide is used as the absorbing liquid of an absorptive cooling and heating machine. That is, a recirculation ratio in the case of a water cooling system can be made small and the shape of an apparatus can be made small while the electric power of a pump and fabrication cost can be lowered. In addition, the crystallization and the clogging of a conc. liquid line due to accidental stoppage during freezing operation can be avoided and diluting operation carried out when operation is finished can be eliminated. Because the absorbent composition has such characteristics that the vapor pressure thereof becomes high in a high temp. range, the conservation of a fuel required in regeneration and the lowering of corrosion in a high temp. part are enabled by lowering a regeneration temp.</p> |
