Single-/double-effect absorption refrigerators that use exhaust heat from fuel cells apply the characteristics of exhaust heat recovered from fuel cells to achieve highly efficient operation. When absorption refrigerators using fuel cell exhaust heat are operated continuously throughout the year, the cooling capacity changes significantly depending on the temperature of the coolant water. Cooling capacity deteriorates with summer operating conditions as compared to winter operating conditions. We thus examined the possibility of improving performance by adding a gas-burning function to supplement the reduced cooling capacity. As a result, we confirmed that we were able to improve the cooling performance as desired.
