Technical Field

Background
Cogeneration (also known as Cogeneration, english: combined heat and power, abbreviated as CHP) utilizes heat engines or power stations to simultaneously generate electricity and useful heat. Triple cogeneration (Trigeneration) or cooling, heat and power cogeneration (CCHP) refers to the simultaneous generation of electricity and useful heat and cooling from fuel burning or solar collectors.
Cogeneration is a thermodynamically efficient use of fuel. In individual power production, some of the energy must be discarded as waste heat, but in cogeneration, some of this heat energy is put into use. The heat emitted by all thermal power plants during power generation can be released to the environment through cooling towers, flue gases or by other means. In contrast, cogeneration captures some or all of the by-products for heating, either very close to the plant, or as hot water for heating living areas, especially in scandinavia and eastern europe, in the temperature range of about 80 to 130 ℃. This is also known as "combined heat and power distributed heating" (abbreviated CHPDH). Small cogeneration plants are an example of decentralized power generation. The heat of the by-product at moderate temperatures (100-.
The Combined Cooling Heating and Power (CCHP) is a poly-generation total energy system which is established on the basis of the concept of cascade utilization of energy and integrates the processes of refrigeration, heat supply (heating and hot water supply) and power generation, and aims to improve the utilization efficiency of energy and reduce the emission of carbide and harmful gas. In the prior art, the side heat of a user and the electric load of the user greatly change along with factors such as seasons, weather, festivals and holidays, so that a domestic distributed energy system operates inefficiently for a long time. Therefore, it is necessary to establish a combined cooling heating and power gas power generation system by mutual conversion between heat and electricity, so as to realize flexible and adjustable heat-power ratio at the supply side, comprehensively consider energy utilization efficiency, improve the total energy efficiency of the combined generation system to the maximum extent, realize comprehensive complementary utilization of renewable energy, meet the product requirements of different users, and improve comprehensive cascade utilization of waste heat resources.
