PURPOSE:To maintain the temperature of air horizontally uniformly to prevent the deterioration of the quality of cargoes by providing a ventilation device for ventilating air in the inside and outside of a container in the middle of an air passage in a refrigerator to blow off the air uniformly to the left and right directions in the container. CONSTITUTION:A recess 42 is formed at a lower central portion of an inside- outside partition wall 41 in a refrigeration device. And a compressor 3, air- cooled condenser 4, water-cooled condenser 5, and condenser fan 6 are provided in the recess 42. On the other hand, a suction chamber 15, an air passage 16, and a blow-off chamber 18 are formed on the upper side of the recess 42, on either side thereof, and on the lower side thereof respectively. By disposing a ventilation device 40 at the center of an air passage of air in a container, i.e., the suction chamber 15, fresh outside air introduced by the device 40 is caused to be uniformly dispersed and blown off horizontally in the container. Consequently, the temperature of air in the container can be made uniform in the lateral direction of the container, thereby preventing the deterioration of the quality of cargoes. |
