A combined power and cooling system

Abstract

An embodiment of the invention discloses a power and refrigeration cogeneration system. The power and refrigeration cogeneration system comprises a wave power generation device, an ocean current power generation device, an ocean thermal energy conversion and solar energy combined power generation subsystem and a refrigeration subsystem. The ocean thermal energy conversion and solar energy combined power generation subsystem comprises a solar thermal collector, the wave power generation device is connected with a first water pump of the ocean thermal energy conversion and solar energy combined power generation subsystem, and the solar thermal collector absorbs solar energy to perform superheat treatment on a working medium of the ocean thermal energy conversion and solar energy combined power generation subsystem. The ocean current power generation device is connected with a second water pump of the ocean thermal energy conversion and solar energy combined power generation subsystem. A cold water output end of a first condenser is connected with an input end of a second condenser of the refrigeration subsystem. The power and refrigeration cogeneration system has advantages that the water pumps are powered by wave energy and ocean current energy, and ocean thermal energy and solar energy are adopted for thermal collection and power generation, so that electricity consumption and energy consumption of the power and refrigeration cogeneration system are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of new energy combined power and cooling, and more specifically relates to a combined power and cooling system driven by ocean temperature difference energy and solar energy. Background technique [0002] With the continuous growth of population and rapid economic development, non-renewable energy sources such as coal, natural gas and oil are facing a crisis of exhaustion, while renewable and environmentally friendly energy sources such as ocean energy, solar energy, and wind energy are attracting attention and promotion. Ocean energy in renewable energy is provided by the ocean, which accounts for 70% of the total area of ​​the earth, and solar energy is currently one of the most widely used energy sources. [0003] However, power supply and cooling in island areas still rely on traditional energy sources, the cost of power supply is high, and the power generation capacity is limited. So far, no combined po...
