Abstract

The invention discloses a solar energy and alternative fuel complementary distributed internal combustion engine cooling heating and power system and method. The system comprises a solar energy and alternative fuel complementary reaction energy-accumulating system, a solar fuel internal combustion engine power generation system, a solar fuel flue gas residual heat absorptive lithium bromide refrigerating system, a flue gas residual heat recovery reaction device, a tail gas residual heat recovery heat exchanger and a cylinder jacket water plate heat exchanger. By adopting solar energy and alternative fuel in a complementary manner, conversion from solar energy to chemical energy of fuel is realized; light-converted synthetic gas fuel is stored and coupled with an internal combustion engine combined cooling heating and power system, so that high energy density is achieved, and the volume of an energy-storing device is reduced. Meanwhile, the aim of realizing multiple functions of combined solar cooling, heating and power at low cost and high efficiency is fulfilled, and separate solar cooling, heating and power at a high cost are avoided, so that the problems of difficulty in accumulating energy, high cost and low efficiency in the conventional solar heat utilization are solved effectively.

Description

technical field [0001] The invention relates to the technical fields of multi-energy complementarity and new energy, energy saving and emission reduction, in particular to a distributed internal combustion engine cooling, heating and power system and method that complement solar energy and alternative fuels. Background technique [0002] The use of solar thermal energy for power generation, refrigeration and heating is one of the main measures to achieve the goal of non-fossil energy accounting for about 15% of primary energy consumption in my country by 2020. However, due to the low energy density, discontinuity and difficulty in energy storage of solar energy, the utilization rate of solar energy is low, and the degree of development and utilization is severely limited. Especially for solar thermal power generation, regardless of the trough-type or tower-type solar thermal power generation technology, the technical bottlenecks such as high cost and low efficiency caused by...
