CCHP Distributed energy One of, with energy conservation , improve the environment, increase the power supply and other comprehensive benefits, which are urban air pollution control and improve energy integration Utilization It is one of the necessary means in line with the national sustainable development strategy. Implemented on January 1, 1998《 Energy Conservation Law of the People's Republic of China 》Article 39 clearly states that "the state encourages the development of the following general Energy saving technology Develop the technology of thermal energy cascade utilization, heat, electricity and cold cogeneration, and improve the comprehensive utilization rate of thermal energy. In September 2004, the National Development and Reform Commission issued the Distributed energy system Report on Issues ", supporting small Distributed energy System development, promote the development of China's distributed energy system. In 2006, the National Development and Reform Commission, together with the Ministry of Finance Ministry of Construction And other relevant departments have prepared the Opinions on the Implementation of Ten Key Energy Conservation Projects during the Eleventh Five Year Plan, clearly proposing that "distributed construction Cogeneration And combined heat, power and cooling; Research and improve the standards and policies related to natural gas distributed cogeneration ". The triple supply system can fully utilize the heat energy of natural gas, and the comprehensive energy utilization efficiency can reach more than 90%. At the same time, it can reduce the Heating cost , spread part of the cost to the electricity bill, and reduce the operation Cost burden Compared with conventional systems, the excess initial investment cost can be recovered within 5 years by saving operating costs. Because of its outstanding advantages in energy conversion efficiency, triple generation has a prominent position in the energy field of most countries in the world.
The cold, heat and power cogeneration system uses gas as the energy source to meet the demand of cold, heat and electricity by utilizing the hot water and high-temperature exhaust gas generated Energy supply System, usually by Generator Set 、 lithium bromide Refrigeration device 、 Heat exchanger The triple supply makes full use of the heat energy of gas, greatly improving the comprehensive utilization efficiency of energy.
