Study Of Configuration Analysis And Integration Application For Building Cooling Heating And Power

BCHP combines the power generation,heating and cooling,which is based on the concept of the energy cogeneration.Its primary energy ratio and safety is much higher than the conventional energy supply mode.It is in favor of environmental protection because its fuel is natural gas which is the most clean energy resource.BCHP system has a smaller generator whose efficiency is smaller than the large generator of the central plant.So in order to make use of its advantage of cogeneration efficiency and local supply,a common step for configuration is put forward according to an example of hotel.The load dynamic simulation software-DeST is used to calculate and make statistics.After that,a prime motor of gas engine ,which is considered the gas supplement and electrical chiller assistant,is contrasted with the conventional energy supply mode from the energy saving effect and economical side.Also,the fuel price has a great impact for its economical side.The way and step for this kind of energy supply system can be extended for the earlier laying and designing stage of BCHP.BCHP which is based on gas engine and smoke-supplement absorption water heating and chilling unit is designed.Besides the waste heat recovery system,this BCHP can run together with the pulic grid,electrical chiller and gas boiler,which has the double energy supply mode.This mode facilitate the user and increase of safety of energy supply.The whole designing flow makes BCHP practical from the academic analysis while it is a meaningful explore in the BCHP engineering application.The local PLC is applied to control the BCHP when the system integration and pipeline design are finished.The sequence and on-off control is realized among the design of outside electrical circuit,analogical data collection,communication and actuator.The whole program is divided to the main program,summar program,winter program,transition...
