Claim 2:
3. The absorption refrigerator according to claim 1,
wherein the approximation function includes a first function and a second function,
wherein the plurality of temperature sensors include:
a first sensor configured to detect a regenerator temperature in the regenerator;
a second sensor configured to detect a cooling water inlet temperature being a temperature of a cooling water on an inlet side of the absorber, the cooling water being to be supplied to the condenser via the absorber;
a third sensor configured to detect a cooling water outlet temperature being a temperature of the cooling water on an outlet side of the condenser, the cooling water to be supplied to the condenser via the absorber;
a fourth sensor configured to detect a cold water outlet temperature being a temperature of a cold water to be supplied from the evaporator to an air conditioner; and
a fifth sensor configured to detect a cold water inlet temperature being a temperature of the cold water returning from the air conditioner to the evaporator,

wherein the calculator is configured to:
apply the plurality of second detection results to the first function to obtain the second concentration of a concentrated solution; and
apply the plurality of second detection results to the second function to obtain the second concentration of a diluted solution, and

wherein the controller is configured to execute abnormality determination of a circulation amount of the absorption liquid in accordance with a concentration difference between the concentrated solution and the diluted solution obtained by the calculator.
