  The present invention relates to an absorption refrigerating machine including an evaporator, an absorber, a regenerator, a condenser, and a solution heat exchanger.

Conventionally, if the absorption chiller is, for example, the first type heat pump type, the refrigerant evaporated from the evaporator is absorbed into the concentrated absorbent by the absorber, and the mixed mixture is sent to the regenerator for heating. By doing so, the concentrated absorbent is separated into the refrigerant and the concentrated absorbent is guided to the absorber.
On the other hand, the separated refrigerant is sent to a condenser to be cooled and condensed. The refrigerant thus obtained is sent to the evaporator via the expansion valve and evaporated to cool the cooling water provided for refrigeration (cooling) flowing through the evaporator.

  In such an absorption chiller, conventionally, a first outer plate, a first partition, a first heat transfer plate, a second partition, and a second outer plate are stacked in order to form a stacked body, and the stacked A first compartment that is partitioned by a first outer plate, a first partition, and a first heat transfer plate; and a second partition that is partitioned by a first heat transfer plate, a second partition, and a second outer plate. A configuration is employed in which the first compartment and the second compartment function as an absorber, an evaporator, and a condenser.

A flow chamber was formed, and an absorption liquid flow chamber through which an absorption liquid that absorbs refrigerant vapor flows was formed on the other side in the horizontal direction. For this reason, the refrigerant vapor has been guided from the refrigerant flow chamber to the absorption liquid flow chamber side through a relatively narrow region between the refrigerant flow chamber and the absorption liquid flow chamber.
For this reason, there existed a problem that the flow velocity of refrigerant | coolant vapor | steam became quick and the efficiency of an absorption refrigerating cycle fell.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a refrigerant vapor in an absorption refrigerator comprising at least an absorber and an evaporator from a plurality of compartments formed of a laminate.
