Novel heat pump water heater suitable for ship

Abstract

A novel heat pump water heater suitable for a ship comprises an evaporator, a working medium pump, a motor, a condenser, a screw expander, a compressor, a generator, a circulating pipeline, a liquid storage tank, an electricity storage box and the like. One part uses the waste gas heat source exhausted through an internal combustion engine as a heat source, an organic working medium in the liquid storage box is heated through exhausted high-temperature waste gas, the organic working medium is converted from the liquid state to the gaseous state, then, steam is injected into the expander to do work through a steam pipe, and one part drives the compressor for heating; and the other part drives the electricity storage box for energy storage through the turbine generator so that the compressor can operate normally and conduct heating when the engine stops working. The novel heat pump water heater can sufficiently recycle heat energy in waste gas of the ship internal combustion engine and is high in utilization rate.

Description

Technical field [0001] The invention belongs to the field of heat pump water heaters, and is specifically a heat pump water heater sourced from the heat of exhaust gas from a marine internal combustion engine. Background technique [0002] As the world’s real economy develops better and better, large ships have become indispensable in international transportation. The energy-saving and emission reduction technologies of the shipping industry have attracted great attention from the international community. We all know that the power plants of large ships are mainly The internal combustion engine uses fuel to convert heat energy into kinetic energy to drive the ship. However, the current level of technology cannot fully utilize the thermal energy generated by the internal combustion engine. About 40% of the energy is not fully utilized, and most of the energy is discharged through waste heat. The air pipe is discharged into the atmosphere to fuel the heat energy is not fully utiliz...

[0002] With the development of the world's real economy getting better and better, large ships have become indispensable in international transportation. The energy saving and emission reduction technology of the shipping industry has attracted great attention from the international community. We all know that the power plant of large ships is mainly The internal combustion engine converts heat energy into kinetic energy through fuel oil to drive the ship. However, the current level of technology cannot fully utilize the heat energy generated by the internal combustion engine. About 40% of the energy is not fully utilized, and most of it is exhausted in the form of waste heat. The air pipe is discharged into the atmosphere to remove fuel and heat energy is not fully utilized
