- the inside of the duct 120 and the front chamber 3a cold air suction chamber 125 flows refrigerated air having a temperature lower than that of the refrigerated air circulating in the rear chamber 3b. Therefore, the duct 120 and the front chamber 3a cool air suction chamber 125 are configured to surround the entire periphery with a heat insulating material (not shown). With such a configuration, condensation on the duct 120 and the rear chamber 3b side of the front chamber 3a cold air suction chamber 125 can be prevented. In this way, dew condensation on the ceiling of the rear chamber 3b is prevented and the cargo is prevented from getting wet.
- the heating / mixing chamber 126 includes a drain pan 127 at the bottom. This is because in the heating / mixing chamber 126, the frozen air in the front chamber 3a sucked from the duct 120 and the refrigerated air in the rear chamber 3b sucked by the blower fan 121 are mixed, so that condensed water is generated.
- the drain pan 127 can guide the generated condensed water to the air guide duct 129 and guide the air from the air guide duct 129 to the floor of the container 3. Condensed water led to the floor is drained out of the container 3 drain (not shown) force container. In this way, cargo wetting is prevented in the rear chamber 3b.
- each of the blower fans 121, 122, and 121 is arranged in a row in the width direction of the container 3 as a total of nine fans by arranging three fans with the same diameter in a row. .
- each fan can be made small, and thus the height dimension of the rear chamber unit 130 can be suppressed. In this way, the effective height for loading and unloading is increased in the rear chamber 3b.
- the heater unit 123 shown in FIGS. 24 and 25 is configured such that the heating element 140 and the support member 141 are integrated.
- the operator can easily attach and detach the heater unit 123 at the time of manufacturing or replacement of the heater unit 123. In this way, the heater unit 123 is improved in assembling and maintenance.
- a shutter 128 is provided in front of the blower fan 122 of the duct 120.
- the shutter 128 is composed of a plate-like elastic body, and its shutter The upper part is fixed to the upper side of the duct 120.
- the shutter 128 is configured so that a weight is attached to the lower part and is in close contact with the lower side.
- the shutter 128 can rotate to the blower fan 122 side at the lower part. That is, when the refrigeration air in the front chamber 3a is sucked by the blower fan 122, the shirt 128 is blown up and the front chamber 3a communicates with the front chamber 3a cool air suction chamber 125. When the blower fan 122 is stopped, the shutter 128 is released. The front chamber 3a is closed and is shut off from the front chamber 3a cold air suction chamber 125. In this way, in the duct 120, the refrigerated air in the front chamber 3a is prevented from naturally flowing into the rear chamber 3b except for forced suction by the blower fan 122.
- the present invention can be used for a refrigeration container having a refrigeration unit on the open end of the container.
