PCT No. PCT/JP97/01400 Sec. 371 Date Dec. 11, 1997 Sec. 102(e) Date Dec. 11, 1997 PCT Filed Apr. 23, 1997 PCT Pub. No. WO97/40327 PCT Pub. Date Oct. 30, 1997The condensed water, as condensed by applying the VRC to a regeneration process, and the strong solution, as fed out of a regenerator, are employed as a heat source to preheat a weak solution so that the preheating amount of the weak solution is increased to improve the performance coefficient of a heat pump. At a heating time, moreover, the solution concentration is raised by utilizing the cooling heat of the absorbent liquid for the hating operations and by reserving a portion of the regenerated refrigerant liquid, thereby to provide a heat pump for the cooling/heating operations
