Claim 1:
2. The absorption refrigerator according to claim 1,
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 configured 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 being configured 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 configured 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 further configured to apply the plurality of second detection results to the approximation function in order to obtain the second concentration of concentrated solution, and
wherein the controller is configured to control, in accordance with the second concentration of the concentrated solution obtained by the calculator, an opening degree of a refrigerant proportional valve configured to control an amount of a refrigerant supplied from the condenser to the evaporator.
