And the system can run around the clock, which ensures the reliability of the system operation, and also reduces the environmental pollution caused by traditional fossil energy to a certain extent.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to an off-grid multi-energy complementary cooling, heating, electricity and humidity cogeneration system and a method thereof. Background technique [0002] At present, the energy supply in scenarios such as remote islands and ships, due to consideration of the high cost of power grid construction and operation and maintenance, currently mainly relies on the off-grid supply mode of the internal combustion engine as the prime mover. At the same time, in order to reduce the consumption of fossil fuels in internal combustion engines and the pollution problems caused by them, the country is also vigorously advocating the development of multi-energy complementary systems that use more renewable energy in combination with the rich natural resources of wind and light at sea. In the off-grid multi-energy complementary system, since renewable energy still has problems such as instability and...

AI Technical Summary

Problems solved by technology

Due to the coupled processing of temperature and humidity, the humidity load of the air conditioner even accounts for more than 50% of the total load, which intensifies the consumption and waste of energy

On the other hand, the power generation efficiency of conventional internal combustion engines is about 40%, and about 62%-66% of the energy is brought into the atmosphere by the exhaust gas and cooling system, and the remaining heat is not efficiently utilized, which further causes energy waste and thermal pollution. question

In addition, the weather at the seaside changes greatly, so far there is no off-grid multi-energy complementary system that can guarantee all-weather operation and supply cold, hot and electric humidity
