Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0021] see figure 2 , Automatic temperature control variable flow ship central cooling system, including fresh water cooling pipeline and seawater cooling pipeline.

[0022] The fresh water cooling pipeline includes a low-temperature fresh water cooling pump 1, cooling equipment 2, a central cooler 3, a low-temperature fresh water cooling pump 1, cooling equipment 2, and the central cooler 3 forming a fresh water circulation pipeline. The equipment to be cooled 2 includes a main engine, a generator, an air conditioner, an air compressor and intermediate bearings, etc., and mainly consumes cold energy in the fresh water cycle. The low-temperature fresh water cooling pump 1 is used as power to drive the entire fresh water circulation system to r...

Abstract

The invention relates to an automatic temperature-control variable flow type central cooling system for a ship, comprising a fresh water cooling pipeline and a seawater cooling pipeline, wherein the fresh water cooling pipeline comprises a low-temperature fresh water cooling pump, a device needing to be cooled and a central cooler which constitute a closed circulation pipeline; the seawater cooling pipeline comprises an open circulation pipeline consisting of a seawater cooling pump and a central cooler; and circulating fresh water flowing through the central cooler is cooled by sea water. The central cooling system is characterized in that the seawater cooling pump is connected with an automatic control unit which can control the seawater flow according to the cooling quantity of the device needing to be cooled. Through the automatic temperature-control variable flow type central cooling system for the ship, under the working condition of non-full load operation of a marine engine system of the ship, the underdeck system energy consumption and the exhaust gas discharge are effectively decreased, the operating cost of the ship is reduced and the concept of environmental friendliness is realized in the meantime.

Description

technical field [0001] The invention relates to the technical field of circulation systems for ships, in particular to a central cooling system for ships. Background technique [0002] At present, the power source of the central cooling system of marine turbines, such as cooling water pumps, etc., after calculation and selection, the flow and pressure generally remain stable during the working process. [0003] see figure 1 , the traditional fresh water cooling pipeline is a closed cycle, driven by the low-temperature fresh water cooling pump 1′, and the low-temperature fresh water (the temperature is T1 at this time) passes through the host, generator, air conditioner, air compressor and intermediate bearings and other cooling equipment 2 After the equipment absorbs heat, the water temperature rises (the temperature is T2 at this time), and the fresh water brings the heat to the central cooler 3' for heat exchange with the cooling seawater, and then the temperature decreas...
