Installation device for freezer for food storage on ship and installation method for refrigeration device for food storage on ship

The present invention relates to a mounting device for a freezer for a grain store on a ship and a method for installing a freezer for a grain store on a ship.

Heretofore, in order to preserve the food required by the crew during the voyage, a food bank is provided on the ship, and a freezer for cooling the inside of the store is provided in the grain store. The freezing device for a grain storage on a ship has the same structure as a freezing device installed on a land in a prehub refrigerator or the like, and has a heat source side unit and a utilization side unit including a compressor and a water-cooled condenser. A condensing unit and an expansion valve plate assembled with an expansion mechanism, the heat source side unit being disposed outside the reservoir. The evaporator and the utilization side fan in the utilization side unit are installed in the casing, and the utilization side unit is disposed in the storage. A refrigerant circuit is formed by sequentially connecting a compressor, a water-cooled condenser, an expansion mechanism, and an evaporator, and the refrigerant circulates in the refrigerant circuit to perform a refrigeration cycle, thereby cooling the interior air in the evaporator. In addition, a cooling water pipe is connected to the water-cooled condenser in the heat source side unit to release the heat of condensation to the cooling water.

Japanese Patent Publication No. 10-205981

In the freezer for the grain storage on the conventional ship, since the heat source side unit is disposed at a position far from the utilization side unit, the connection line of the refrigerant circuit across the heat source side unit and the utilization side unit is longer; It is also necessary to install the cooling water pipe, the installation time is increased, and the installation cost is increased. All of the above are problems. Also, it is difficult to secure a space for the heat source side unit in a narrow ship.

In view of this, it is conceivable to provide a refrigeration system in which an air-cooled condenser is used and the heat source side unit and the use side unit are integrally formed. The integrated refrigerating device installed in the land is also an integrated refrigerating device. However, since a large space can be secured above or around the land, the integrated refrigerating device is installed from the outside of the storage to the ceiling or according to the following steps. On the side wall surface (for example, refer to Patent Document 1), that is, an opening is formed in the ceiling surface and the side wall surface of the prefabricated refrigerator, and the utilization side unit of the integrated refrigeration system passes through the opening from the outside of the library and allows it to be located in the library. In this state, the integrated refrigeration unit is attached from the outside of the storage to the ceiling surface or the side wall surface.

However, because of the large load such as the sway caused by the waves, a huge beam is installed in the ship; the ceiling surface and the side wall other than the door corresponding to the entrance and exit in the grain store are almost all constructed by the hull. That is, the iron plate is covered, so that it is not possible to secure a space for installing the integrated refrigeration unit on the ceiling surface of the grain storage in a ship like a land prefabricated refrigerator; because the food storage is set in a limited space inside the ship. Therefore, it is impossible to ensure a wide space on the side of the grain store. As a result, even if the space for the integrated freezer can be secured on the side wall of the grain store, it is difficult to carry out the grain from the outside of the store because the space on the side of the grain store is narrow. Loading and unloading operations of the library and maintenance work of the grain bank from the outside of the library. Therefore, the desired freezer for the grain storage on the ship is a refrigeration device in which the heat source side unit and the use side unit are integrally connected to the inside of the storage of the grain storage.
