Multi-energy complementary ship cold and hot water system

Abstract

The invention belongs to the technical field of ship waste heat utilization, energy conservation and emission reduction, and particularly relates to a multi-energy complementary ship cold and hot water system which can meet ship cold and hot water supply under various operation working conditions of a ship and comprises a smoke loop, a steam loop, a cylinder sleeve water loop, a cooling water loop, a chilled water loop, a heat pump working medium loop and a domestic water loop. The smoke loop and the heat pump working medium loop belong to heating loops and are used for making domestic hot water by utilizing heat in smoke of a marine main engine and a generator set or heat of solar energy. The steam loop and the cylinder sleeve water loop belong to refrigeration loops and are used for meeting the cold load requirement of a ship. And the chilled water loop is mainly used for cooling a ship cabin. And meanwhile, the heat pump working medium loop can also play a role in cooling the cabin.In the actual operation process of the ship, the smoke loop, the steam loop, the cylinder sleeve water loop, the chilled water loop and the ship heat pump working medium heating loop supplement one another to meet the cold and hot load requirements of the ship under various working conditions.

Description

technical field [0001] The invention belongs to the technical field of ship waste heat utilization, energy saving and emission reduction, and specifically relates to a multi-energy complementary ship cold and hot water system, which can meet the ship's cold and hot water supply under various operating conditions of the ship. [0002] technical background [0003] The shipping industry is an important pillar supporting the development of human society, and ocean transportation occupies the most important position in international logistics. About 90% of the world's cargo transportation is carried by ships. With the gradual deepening of global economic integration, my country has become one of the world's shipping powers. A large amount of fossil energy consumption has caused serious environmental pollution, and has also reduced the economy of ships. Today, when issues such as shortage of energy resources and serious environmental pollution are of global concern, how to save en...

AI Technical Summary

Problems solved by technology

First of all, the flue gas passing through the exhaust gas turbocharger of the main engine is directly used to produce domestic hot water, so that the heat in the exhaust gas is not fully utilized, resulting in a certain degree of energy waste

Secondly, when the ship sails in the low-latitude sea area for a long time, due to the high sea temperature, the heat taken away by the sea water is reduced, and the effect of the refrigeration circuit becomes poor, which leads to the inability to meet the cooling demand of the ship's cabin
