Ship ice-temperature cold storage

Abstract

The invention discloses a ship ice-temperature cold storage which comprises a plurality of cold storages and a refrigerating system. Each cold storage comprises an inner coaming and an outer coaming, and an air interlayer is arranged between the inner coaming and the outer coaming. The refrigerating system comprises a refrigerating compressor and a cooling unit, the refrigerating compressor is arranged outside the cold storage, the cooling unit is arranged inside the cold storage and comprises at least one group of air feeders, the air feeders are arranged in the air interlayer at the top of the cold storage, air inlets of the air feeders are communicated with the air interlayer, side plates are arranged between the inner coaming and the outer coaming at the top of the cold storage and enclose a static pressure box, vent holes are formed in the top and the bottom of the inner coaming, and air outlets of the air feeders are positioned in the static pressure box. The ship ice-temperature cold storage is simple in structure, capable of storing various foods, long in preservation cycle, fine in preservation effect and suitable for occasions such as ships requiring long preservation cycle.

Description

technical field [0001] The invention relates to a cold storage, in particular to an ice-temperature cold storage for ships. Background technique [0002] As we all know, many foods such as fish, meat, dairy products, vegetables, and fruits often rot and deteriorate at room temperature. In order to ensure the quality of life of the crew, the low-temperature storage method of the marine cold storage can be used in Maintaining the original quality of food for a longer period of time is an effective method in various types of ships, and it is also an indispensable equipment for various types of ships. At present, multi-temperature cold storage is mostly used in ship cold storage to store different foods. Usually, freezer and cold storage are used. The temperature of the freezer is mostly below -8°C. The disadvantage is that nutrients will be lost when freezing; The temperature is mostly around 3°C-6°C. The disadvantage is that the fresh-keeping time is short, usually about 6 da...

At present, multi-temperature cold storage is mostly used in ship cold storage to store different foods. Usually, freezer and cold storage are used. The temperature of the freezer is mostly below -8°C. The disadvantage is that nutrients will be lost when freezing; The temperature is mostly around 3°C-6°C. The disadvantage is that the fresh-keeping time is short, usually about 6 days, and it is not suitable for ocean-going operations.

In addition, multiple cold stores with different temperatures are used, the refrigeration system has a complex structure, takes up a lot of space, and is difficult to maintain
