PURPOSE: An absorptive freezer is provided to improve the efficiency of a solution heat exchanger by forming multiple tubes in a solution heat exchanger to flow weak solution and concentrated solution and by changing the flow. CONSTITUTION: A weak solution vented from a solution pump(70) flows into a heat exchange space(214) of low temperature via a first pipe(232) formed on the lower part of a first plate(230) and via a weak solution intake hole(220) formed on the outer side of a second housing(210). The weak solution flowed into the heat exchange space of low temperature is sent to a low temperature regenerator(40) via an exchange space(216) of high temperature heat and a weak solution discharge hole(220a) via a second bypass pipe(238). And the concentrated solution in the low temperature regenerator flows into the heat exchange space of high temperature via a second pipe(234) of a first plate(230) and a concentrated solution intake hole(218) and then into the heat exchange space of low temperature formed on the lower part by passing through a first bypass pipe(236) formed on the end. The concentrated solution is sprayed to an absorber(10) by passing through a concentrated solution discharge hole(218a) and mixed with the small part of the weak solution. Thereby, the sufficient heat exchange of the concentrated solution and the weak solution is performed. |
