Description

Technical Field

[0001] The utility model relates to the technical field of ship cabin refrigeration, in particular to a mobile coil refrigeration fan and a ship cooling system. Background Art

[0002] Each type of ship is equipped with an air conditioning system. When the ship is moored at the dock, if the ship-borne air conditioning system is used for cooling, it will not only consume a lot of energy and cost, but also require special duty personnel. In addition, the operation of the ship-borne air conditioning system during the docking period will accelerate the wear of these equipment, increase the frequency of repair and maintenance, and the service life will be out of sync with other equipment on the ship, which will shorten the service life when sailing at sea. Especially during the dock repair period of the ship, the air conditioning system cannot be started due to the lack of cooling water, the cabin temperature is too high, and the workers' work efficiency is very low. More importantly, various electronic equipment cannot be started normally, and they cannot be debugged and repaired. The humid air will corrode the equipment more seriously. Therefore, the failure rate of electronic equipment will not only not decrease, but will increase. If the various electronic equipment are debugged after the ship is out of the dock and the air conditioning system starts working, it will cause the ship's electromechanical and maintenance to be out of sync, extending the maintenance cycle. For this reason, the dock has a shore-supplied refrigeration station, which relies on the external circulation of chilled water to output cooling capacity.

[0003] Due to factors such as ship space, power, and navigation characteristics, the use of air conditioning systems on ships is limited in different locations. The temperature is greatly affected by the environment and is difficult to control. In addition, ships generally do not have interfaces for connecting to shore-supplied chilled water. This makes it impossible to directly use shore-supplied chilled water to cool and dehumidify the cabins of ships.

[0004] At present, no effective solution has been proposed for the problems existing in related technologies such as the high energy consumption cost of using shipboard air-conditioning systems to provide cooling in ship spaces. Utility Model Content

[0159] The air temperature is lowered by the heat exchange element 131 and then transported to the ship cabin through the gas exchange element 121. At the same time, the liquid in the second pipe element 132 and the third pipe element 133 takes away the heat generated by the heat exchange element 131 under the action of the circulation element 141.

[0160] After the equipment is used, the first liquid discharge element 135 is opened to discharge the accumulated liquid in the second pipe element 132 and the third pipe element 133 to avoid water freezing and thus causing damage to the equipment.

[0161] The advantage of the utility model is that by integrating a gas exchange unit, a heat exchange unit and a circulation unit inside the shell unit, the mobile coil refrigeration fan can be connected to the refrigeration station at the dock to cool the ship space, thereby solving the problem of high energy consumption cost of using the shipboard air-conditioning system to supply cooling to the ship space.

[0178] In some embodiments, the number of the moving units 180 is 4. The 4 moving units 180 are arranged in an array at the bottom of the frame element 111 .

[0179] In some of the embodiments, the moving unit 180 is a pulley with a brake structure.

[0180] In some of the embodiments, the mobile unit 180 may be a universal wheel or a fixed wheel.

[0181] The advantage of this embodiment is that, by providing a moving unit, manual movement is facilitated when position adjustment within a small range is required.

[0182] Example 4

[0183] This embodiment relates to a ship cooling system of the utility model.
