Marine salt water cooling system with cold bridge preventing function and mounting method thereof

Abstract

The invention discloses a marine salt water cooling system with a cold bridge preventing function and a mounting method thereof. Sealed outer shells are arranged outside a salt water cooling compressor unit, a cooling salt water pump, a mixed salt water pump, a salt water lightering pump and an air cooler correspondingly; a controller is further included; a pipeline comprises an inner pipe and anouter pipe which are concentrically arranged; air holes are formed in the outer shells and the outer pipe correspondingly, and solenoid valves are arranged in the air holes; and the salt water coolingcompressor unit, the cooling salt water pump, the mixed salt water pump, the salt water lightering pump, the air cooler and the solenoid valves are connected with the controller. The mounting methodof the marine salt water cooling system comprises the steps: mounting of salt water cooling system equipment, laying of the pipeline, and pouring of a secondary refrigerant. According to the system, avacuum negative pressure environment is set outside the equipment and the pipeline so as to avoid the cold bridge phenomenon outside the salt water cooling system, thus the salt water cooling systemhas a good heat preservation effect, and then a cargo hold better keeps fresh for cargoes such as fruit juice; and the mounting method of the system is simple, and industrial application and implementation of the marine salt water cooling system are facilitated.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a marine salt water cooling system with the function of preventing cold bridges and an installation method thereof. Background technique [0002] The juice carrier is a low-temperature fresh-keeping carrier with independent cargo tanks in the cargo hold. The ship is like a "refrigerator" that moves at sea, and its cargo hold needs to maintain a low temperature environment. In order to prevent oxidation and bacterial contamination of fruit juice during transportation, it is necessary to control the temperature in the cargo hold within the range of 0-10°C for a long time. In order to insulate and insulate the cargo area of ​​the traditional liquid transport cargo ship, the external environment is often used to cool the tank, and the cooling and exchange of the cargo is carried out in the form of internal circulation. However, the marine brine cooling system in the prior art ha...

Problems solved by technology

In order to insulate and insulate the cargo area of ​​the traditional liquid transport cargo ship, the external environment is often used to cool the tank, and the cooling and exchange of the cargo is carried out in the form of internal circulation. On the one hand, because the temperature of the refrigerant in the pipeline is lower than zero, there will be a "cold bridge phenomenon" outside the pipeline or equipment, which will reduce the performance of the pipeline or equipment or even fail to guarantee normal operation
