Ship cabin heating system taking fuel cell cooling water as heat source

Abstract

The invention provides a ship cabin heating system taking fuel cell cooling water as a heat source. The ship cabin heating system comprises a fuel cell cooling loop, a heating pipeline and an external water passage, the fuel cell cooling loop is respectively connected with the external water passage and the heating pipeline; a fuel cell and a second convection heat exchanger are arranged in the fuel cell cooling loop, and after the fuel cell operates, discharged heat dissipation water is conveyed into the second convection heat exchanger and the heating pipeline; external water is conveyed into the second convection heat exchanger through the external water channel, exchanges heat with heat dissipation water and then is discharged into the external environment; and after the heat dissipation water conveyed into the heating pipeline supplies heat to the interior of the cabin, the heat dissipation water and the heat dissipation water subjected to heat exchange in the second convection heat exchanger are gathered into one path to be conveyed into the fuel cell. The system is energy-saving and environment-friendly, the waste heat of the cooling water of the fuel cell which is originally directly discharged is used for heating the ship, high-grade electric energy originally used for heating can be saved, fuel consumption is reduced, and the economy of the fuel cell ship is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of marine fuel cell systems, in particular to a heating system for a ship's cabin using fuel cell cooling water as a heat source. Background technique [0002] In recent years, the shipping industry is facing severe energy conservation and emission reduction problems. In order to alleviate the pollution of the atmospheric environment caused by ship emissions and the consumption of fossil energy, my country attaches great importance to the development of green shipping and the development of new energy sources for ships. In the current new energy application technology, fuel cells using hydrogen as fuel have the advantages of low pollution, low noise, and high efficiency, and have broad application prospects in the shipbuilding field. A hydrogen fuel cell is a device that uses the chemical energy of hydrogen to directly convert electrical energy and thermal energy, wherein the thermal energy generated...
