The Research Of The Combined Cooling Heating And Power System In Changsha Huanghua International Airport

As the development of economy,energy supply issues are becoming increasingly prominent,They realize the energy,the environment and economical coordinated development has become the inevitable trend.As a new energy supply technology,the system of combined cooling heating and power and it receives much attention in the worldwide,So it has the broad prospect and practical significance.This topic come from CCHP construction projects of Changsha ENN Huanghua International Airport.Base on combined the surrounding environment investigation and theory analysis and design to research the project.Firstly,according to the specific circumstance of huanghua airport,elaborated power access conditions,gas access conditions,control system optimization and energy prices and Changsha Huanghua airport meteorological and hydrological environment conditions,etc.,analysing the Huanghua airport using CCHP system scheme is feasible.Then the paper base on analysis the cooling,heating and power load's variation of T2 terminal to forecast the T3 terminal's cooling,heating and power load.This subject use the CCHP system,one can make full use of electricity,and another,we can make full use of waste heat power to get heating or cooling power and achieve the energy cascade utilization.Second,according to the Huanghua airport project technology and energy characteristics,put forward three kinds of schemes.Through analyse the advantages and disadvantages of each scheme,we can choose a suitable plan.And elaborated the scheme should take which energy saving measures,and the scheme's environmental benefits are analyzed.Through analyse the emissions of pollutions,such as waste water and waste gas are discharged from the station,impact on surrounding environment.And discusses the CCHP system's advantages in the area of environmental protection.Research the several key links of the Huanghua airport project.From the aspect of power access,through analyse led to use two 836kw gas diesel generator respectively access to T3 terminal 2#control room's two section 10kv high voltage bus,it is suitable to adopt the method of grid-connected but not transfer power to the grid.At the same time,the project also has good gas access conditions.And this project put forward the goal of automatic control system,the measures fire fighting.ect.Through stuy huanghua airport gas trigeneration project,illustrates the feasibility of gas trigeneration system,the CCHP system achieve the temperature cascade utilization,on the one hand,improve the energy efficiency and respond to government orders of energy conservation and emission reduction,and also can help the user to save energy costs,has the good economic efficiency.
