Analysis Of Compound Cooling Heating And Power’s Gas Load

The energy conservation and improvement of energy efficiency are the most importantissues of China’s energy strategy and also the only way for China’s sustainable development.The research on distributed energy systems has been paid more attention.The so-called "distributed energy" refers to the energy utilization system distributed on theclient, which is based on generation technology of cold, heat and electricity[1]. The systemprovides power, steam, hot water and cold air conditioning (or air) as well as some otherenergy services for a certain area of users with large electrical grid and gas pipeline networkoperating together.The distributed energy system has many disadvantages, which is close to the user and isconducive to security of energy supply, environmental protection, the energy cascadeutilization and high efficiency of primary energy use etc. So it have been governments,business, energy, science and technology workers attention.Firstly, the power equipment (natural gas internal combustion engines, gas turbines) ofCCHP are analyzed, especially heat recovery equipment.Secondly, the main form of CCHP is introduced and outlined, following the configurationprinciple.Three typical public commercial buildings (an office building, a hotel and a building ofhospital) are selected as the target architectures. The annual hourly electric and cooling loadof the target building can be calculated out by the use of simulation software eQUEST. Thenthe different system options, the form of combination and the type of units can be decided.Finally, the gas load of the target building can be calculated by the heat to electrical powermethod and the electrical power to heat method, and then it be analyzed.
