Abrégé
(EN)
An evaporative-cooling condensation type ammonia refrigeration unit with leaked ammonia gas removing means is provided. Recovery of a leaked ammonia gas is conducted taking advantage of a high solubility of ammonia in water, wherein the leaked ammonia gas is dissolved in a cooling water used for an evaporative condenser. The construction of the unit is characterized by including an ammonia absorptive structure in a gas/liquid countercurrent mode provided in a space on the lower side of the evaporative condenser accommodated in an upper chamber.
